nicardipine hydrochloride

Dosage Form: injection
Cardene I.V.®

(nicardipine hydrochloride)

Rx only



Cardene Injection Description


Cardene ® (nicardipine HCI) is a calcium ion influx inhibitor (slow channel blocker or calcium channel blocker). Cardene ® I.V. for intravenous administration contains 2.5 mg/mL of nicardipine hydrochloride. Nicardipine hydrochloride is a dihydropyridine derivative with IUPAC (International Union of Pure and Applied Chemistry) chemical name (±)-2-(benzyl-methyl amino) ethyl methyl 1,4-dihydro-2,6-dimethyl-4-(m-nitrophenyl)-3,5- pyridinedicarboxylate monohydrochloride and has the following structure: Nicardipine hydrochloride is a greenish-yellow, odorless, crystalline powder that melts at about 169°C. It is freely soluble in chloroform, methanol, and glacial acetic acid, sparingly soluble in anhydrous ethanol, slightly soluble in n-butanol, water, 0.01 M potassium dihydrogen phosphate, acetone, and dioxane, very slightly soluble in ethyl acetate, and practically insoluble in benzene, ether, and hexane. It has a molecular weight of 515.99. Cardene ® l.V. is available as a sterile, non-pyrogenic, clear, yellow solution in 10 mL ampuls for intravenous infusion after dilution. Each mL contains 2.5 mg nicardipine hydrochloride in Water for Injection, USP with 48.00 mg Sorbitol, NF, buffered to pH 3.5 with 0.525 mg citric acid monohydrate, USP and 0.09 mg sodium hydroxide, NF. Additional citric acid and/or sodium hydroxide may have been added to adjust pH.




Cardene Injection - Clinical Pharmacology



Mechanism of Action


Nicardipine inhibits the transmembrane influx of calcium ions into cardiac muscle and smooth muscle without changing serum calcium concentrations. The contractile processes of cardiac muscle and vascular smooth muscle are dependent upon the movement of extracellular calcium ions into these cells through specific ion channels. The effects of nicardipine are more selective to vascular smooth muscle than cardiac muscle. In animal models, nicardipine produced relaxation of coronary vascular smooth muscle at drug levels which cause little or no negative inotropic effect.



Pharmacokinetics and Metabolism


Following infusion, nicardipine plasma concentrations decline tri-exponentially, with a rapid early distribution phase (α−half-life of 2.7 minutes), an intermediate phase (β-half-life of 44.8 minutes), and a slow terminal phase (γ-half-life of 14.4 hours) that can only be detected after long-term infusions. Total plasma clearance (Cl) is 0.4 L/hr•kg, and the apparent volume of distribution (Vd) using a non-compartment model is 8.3 L/kg. The pharmacokinetics of Cardene ® l.V. are linear over the dosage range of 0.5 to 40.0 mg/hr.


Rapid dose-related increases in nicardipine plasma concentrations are seen during the first two hours after the start of an infusion of Cardene ® I.V. Plasma concentrations increase at a much slower rate after the first few hours, and approach steady state at 24 to 48 hours. On termination of the infusion, nicardipine concentrations decrease rapidly, with at least a 50% decrease during the first two hours post-infusion. The effects of nicardipine on blood pressure significantly correlate with plasma concentrations.


Nicardipine is highly protein bound (>95%) in human plasma over a wide concentration range.


Cardene ® I.V. has been shown to be rapidly and extensively metabolized by the liver. After coadministration of a radioactive intravenous dose of Cardene ® I.V. with an oral 30 mg dose given every 8 hours, 49% of the radioactivity was recovered in the urine and 43% in the feces within 96 hours. None of the dose was recovered as unchanged nicardipine.


Nicardipine does not induce or inhibit its own metabolism and does not induce or inhibit hepatic microsomal enzymes. The steady-state pharmacokinetics of nicardipine are similar in elderly hypertensive patients (>65 years) and young healthy adults.



Hemodynamics


Cardene ® I.V. produces significant decreases in systemic vascular resistance. In a study of intra-arterially administered Cardene ® I.V., the degree of vasodilation and the resultant decrease in blood pressure were more prominent in hypertensive patients than in normotensive volunteers. Administration of Cardene ® I.V. to normotensive volunteers at dosages of 0.25 to 3.0 mg/hr for eight hours produced changes of <5 mmHg in systolic blood pressure and <3 mmHg in diastolic blood pressure.


An increase in heart rate is a normal response to vasodilation and decrease in blood pressure; in some patients these increases in heart rate may be pronounced. In placebo-controlled trials, the mean increases in heart rate were 7 ± 1 bpm in postoperative patients and 8 ± 1 bpm in patients with severe hypertension at the end of the maintenance period. Hemodynamic studies following intravenous dosing in patients with coronary artery disease and normal or moderately abnormal left ventricular function have shown significant increases in ejection fraction and cardiac output with no significant change, or a small decrease, in left ventricular end-diastolic pressure (LVEDP). There is evidence that Cardene ® increases blood flow. Coronary dilatation induced by Cardene ® I.V. improves perfusion and aerobic metabolism in areas with chronic ischemia, resulting in reduced lactate production and augmented oxygen consumption. In patients with coronary artery disease, Cardene ® I.V., administered after beta-blockade, significantly improved systolic and diastolic left ventricular function. In congestive heart failure patients with impaired left ventricular function, Cardene ® I.V. increased cardiac output both at rest and during exercise. Decreases in left ventricular end-diastolic pressure were also observed. However, in some patients with severe left ventricular dysfunction, it may have a negative inotropic effect and could lead to worsened failure.


“Coronary steal” has not been observed during treatment with Cardene ® I.V. (Coronary steal is the detrimental redistribution of coronary blood flow in patients with coronary artery disease from underperfused areas toward better perfused areas.) Cardene ® I.V. has been shown to improve systolic shortening in both normal and hypokinetic segments of myocardial muscle. Radionuclide angiography has confirmed that wall motion remained improved during increased oxygen demand. (Occasional patients have developed increased angina upon receiving oral nicardipine. Whether this represents coronary steal in these patients, or is the result of increased heart rate and decreased diastolic pressure, is not clear.)


In patients with coronary artery disease, Cardene ® I.V. improves left ventricular diastolic distensibility during the early filling phase, probably due to a faster rate of myocardial relaxation in previously underperfused areas. There is little or no effect on normal myocardium, suggesting the improvement is mainly by indirect mechanisms such as afterload reduction and reduced ischemia. Cardene ® I.V. has no negative effect on myocardial relaxation at therapeutic doses. The clinical benefits of these properties have not yet been demonstrated.



Electrophysiologic Effects


In general, no detrimental effects on the cardiac conduction system have been seen with Cardene ® I.V. During acute electrophysiologic studies, it increased heart rate and prolonged the corrected QT interval to a minor degree. It did not affect sinus node recovery or SA conduction times. The PA, AH, and HV intervals* or the functional and effective refractory periods of the atrium were not prolonged. The relative and effective refractory periods of the His-Purkinje system were slightly shortened.


* PA = conduction time from high to low right atrium; AH = conduction time from low right atrium to His bundle deflection, or AV nodal conduction time; HV = conduction time through the His bundle and the bundle branch-Purkinje system.



Hepatic Function


Because the liver extensively metabolizes nicardipine, plasma concentrations are influenced by changes in hepatic function. In a clinical study with oral nicardipine in patients with severe liver disease, plasma concentrations were elevated and the half-life was prolonged (see “Precautions”). Similar results were obtained in patients with hepatic disease when Cardene ® I.V. (nicardipine hydrochloride) was administered for 24 hours at 0.6 mg/hr.



Renal Function


When Cardene ® I.V. was given to mild to moderate hypertensive patients with moderate degrees of renal impairment, significant reduction in glomerular filtration rate (GFR) and effective renal plasma flow (RPF) was observed. No significant differences in liver blood flow were observed in these patients. A significantly lower systemic clearance and higher area under the curve (AUC) were observed.


When oral nicardipine (20 mg or 30 mg TID) was given to hypertensive patients with impaired renal function, mean plasma concentrations, AUC, and Cmax were approximately two-fold higher than in healthy controls. There is a transient increase in electrolyte excretion, including sodium (see “Precautions”).


Acute bolus administration of Cardene ® I.V. (2.5 mg) in healthy volunteers decreased mean arterial pressure and renal vascular resistance; glomerular filtration rate (GFR), renal plasma flow (RPF), and the filtration fraction were unchanged. In healthy patients undergoing abdominal surgery, Cardene ® I.V. (10 mg over 20 minutes) increased GFR with no change in RPF when compared with placebo. In hypertensive type ll diabetic patients with nephropathy, oral nicardipine (20 mg TID) did not change RPF and GFR, but reduced renal vascular resistance.



Pulmonary Function


In two well-controlled studies of patients with obstructive airway disease treated with oral nicardipine, no evidence of increased bronchospasm was seen. In one of the studies, oral nicardipine improved forced expiratory volume 1 second (FEV1) and forced vital capacity (FVC) in comparison with metoprolol. Adverse experiences reported in a limited number of patients with asthma, reactive airway disease, or obstructive airway disease are similar to all patients treated with oral nicardipine.



Effects in Hypertension


In patients with mild to moderate chronic stable essential hypertension, Cardene ® I.V. (0.5 to 4.0 mg/hr) produced dose-dependent decreases in blood pressure, although only the decreases at 4.0 mg/hr were statistically different from placebo. At the end of a 48-hour infusion at 4.0 mg/hr, the decreases were 26.0 mmHg (17%) in systolic blood pressure and 20.7 mmHg (20%) in diastolic blood pressure. In other settings (e.g., patients with severe or postoperative hypertension), Cardene ® I.V. (5 to 15 mg/hr) produced dose-dependent decreases in blood pressure. Higher infusion rates produced therapeutic responses more rapidly. The mean time to therapeutic response for severe hypertension, defined as diastolic blood pressure ≤95 mmHg or ≥25 mmHg decrease and systolic blood pressure ≤160 mmHg, was 77 ± 5.2 minutes. The average maintenance dose was 8.0 mg/hr. The mean time to therapeutic response for postoperative hypertension, defined as ≥15% reduction in diastolic or systolic blood pressure, was 11.5 ± 0.8 minutes. The average maintenance dose was 3.0 mg/hr.



Indications and Usage for Cardene Injection


Cardene ® I.V. is indicated for the short-term treatment of hypertension when oral therapy is not feasible or not desirable. For prolonged control of blood pressure, transfer patients to oral medication as soon as their clinical condition permits (see “Dosage and Administration”).



Contraindications


Cardene® I.V. is contraindicated in patients with advanced aortic stenosis because part of the effect of Cardene® I.V. is secondary to reduced afterload. Reduction of diastolic pressure in these patients may worsen rather than improve myocardial oxygen balance.



Warnings



Use in Patients with Angina


Increases in frequency, duration, or severity of angina have been seen in chronic oral therapy with oral nicardipine. Induction or exacerbation of angina has been seen in less than 1% of coronary artery disease patients treated with Cardene ® I.V. The mechanism of this effect has not been established.



Use in Patients with Heart Failure


Titrate slowly when using Cardene ® I.V., particularly in combination with a beta-blocker, in patients with heart failure or significant left ventricular dysfunction because of possible negative inotropic effects.



Intravenous Infusion Site


To reduce the possibility of venous thrombosis, phlebitis, local irritation, swelling, extravasation, and the occurrence of vascular impairment, administer drug through large peripheral veins or central veins rather than arteries or small peripheral veins, such as those on the dorsum of the hand or wrist. To minimize the risk of peripheral venous irritation, change the site of the drug infusion every 12 hours.



Precautions



General


Blood Pressure: In administering nicardipine, close monitoring of blood pressure and heart rate is required. Nicardipine may occasionally produce symptomatic hypotension or tachycardia. Avoid systemic hypotension when administering the drug to patients who have sustained an acute cerebral infarction or hemorrhage.


Use in Patients with Impaired Hepatic Function: Since nicardipine is metabolized in the liver, consider lower dosages and closely monitor responses in patients with impaired liver function or reduced hepatic blood flow.


Use in Patients with Impaired Renal Function: When Cardene ® I.V. was given to mild to moderate hypertensive patients with moderate renal impairment, a significantly lower systemic clearance and higher area under the curve (AUC) was observed. These results are consistent with those seen after oral administration of nicardipine. Titrate gradually in patients with renal impairment.



Drug Interactions


Beta Blockers


In most patients, Cardene ® I.V. can safely be used concomitantly with beta-blockers. However, titrate slowly when using Cardene ® I.V. in combination with a beta-blocker in heart failure patients.


Cimetidine


Cimetidine has been shown to increase nicardipine plasma concentrations with oral nicardipine administration. Frequently monitor response in patients receiving both drugs. Data with other histamine-2 antagonists are not available.


Cyclosporine


Concomitant administration of oral nicardipine and cyclosporine results in elevated plasma cyclosporine levels. Closely monitor plasma concentrations of cyclosporine during Cardene ® I.V. administration, and reduce the dose of cyclosporine accordingly.


In Vitro Interaction


The plasma protein binding of nicardipine was not altered when therapeutic concentrations of furosemide, propranolol, dipyridamole, warfarin, quinidine, or naproxen were added to human plasma in vitro.



CARCINOGENESIS, MUTAGENESIS, IMPAIRMENT OF FERTILITY


Rats treated with nicardipine in the diet (at concentrations calculated to provide daily dosage levels of 5, 15, or 45 mg/kg/day) for two years showed a dose-dependent increase in thyroid hyperplasia and neoplasia (follicular adenoma/carcinoma). One- and three-month studies in the rat have suggested that these results are linked to a nicardipine-induced reduction in plasma thyroxine (T4) levels with a consequent increase in plasma levels of thyroid stimulating hormone (TSH). Chronic elevation of TSH is known to cause hyperstimulation of the thyroid. In rats on an iodine deficient diet, nicardipine administration for one month was associated with thyroid hyperplasia that was prevented by T4 supplementation. Mice treated with nicardipine in the diet (at concentrations calculated to provide daily dosage levels of up to 100 mg/kg/day) for up to 18 months showed no evidence of neoplasia of any tissue and no evidence of thyroid changes. There was no evidence of thyroid pathology in dogs treated with up to 25 mg nicardipine/kg/day for one year and no evidence of effects of nicardipine on thyroid function (plasma T4 and TSH) in man. There was no evidence of a mutagenic potential of nicardipine in a battery of genotoxicity tests conducted on microbial indicator organisms, in micronucleus tests in mice and hamsters, or in a sister chromatid exchange study in hamsters. No impairment of fertility was seen in male or female rats administered nicardipine at oral doses as high as 100 mg/kg/day (human equivalent dose about 16 mg/kg/day, 8 times the maximum recommended oral dose).



Pregnancy Category C


There are no adequate and well-controlled studies of nicardipine use in pregnant women. However, limited human data in pregnant women with preeclampsia or pre-term labor are available. In animal studies, no embryotoxicity occurred in rats with oral doses 8 times the maximum recommended human dose (MRHD) based on body surface area (mg/m2), but did occur in rabbits with oral doses at 24 times the maximum recommended human dose (MRHD) based on body surface area (mg/m2). Cardene ® I.V. should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Hypotension, reflex tachycardia, postpartum hemorrhage, tocolysis, headache, nausea, dizziness, and flushing have been reported in pregnant women who were treated with intravenous nicardipine for hypertension during pregnancy. Fetal safety results ranged from transient fetal heart rate decelerations to no adverse events. Neonatal safety data ranged from hypotension to no adverse events.


Adverse events in women treated with intravenous nicardipine during pre-term labor include pulmonary edema, dyspnea, hypoxia, hypotension, tachycardia, headache, and phlebitis at site of injection. Neonatal adverse event include acidosis (pH<7.25).


In embryofetal toxicity studies, nicardipine was administered intravenously to pregnant rats and rabbits during organogenesis at doses up to 0.14 times the MRHD based on body surface area (mg/m2) (5 mg/kg/day) (rats) and 0.03 times the MRHD based on body surface area (mg/m2) (0.5 mg/kg/day) (rabbits). No embryotoxicity or teratogenicity was seen at these doses. Embryotoxicity, but no teratogenicity was seen at 0.27 times the MRHD based on body surface area (mg/m2) (10 mg/kg/day) in rats and at 0.05 times the MRHD based on body surface area (mg/m2) (1 mg/kg/day) in rabbits.


In other animal studies, pregnant Japanese White rabbits received oral nicardipine during organogenesis, at doses 8 and 24 times the MRHD based on body surface area (mg/m2) (50 and 150 mg/kg/day). Embryotoxicity occurred at the high dose along with signs of maternal toxicity (marked maternal weight gain suppression). New Zealand albino rabbits received oral nicardipine during organogenesis, at doses up to 16 times the MRHD based on body surface area (mg/m2) (100 mg nicardipine/kg/day). While significant maternal mortality occurred, no adverse effects on the fetus were observed. Pregnant rats received oral nicardipine from day 6 through day 15 of gestation at doses up to 8 times the MRHD based on body surface area (mg/m2) (100 mg/kg/day). There was no evidence of embryotoxicity or teratogenicity; however, dystocia, reduced birth weights, reduced neonatal survival, and reduced neonatal weight gain were noted.



Nursing Mothers


Nicardipine is minimally excreted into human milk. Among 18 infants exposed to nicardipine through breast milk in the postpartum period, calculated daily infant dose was less than 0.3 mcg and there were no adverse events observed. Consider the possibility of infant exposure when using nicardipine in nursing mothers.


In a study of 11 women who received oral nicardipine 4 to 14 days postpartum, 4 women received immediate-release nicardipine 40 to 80 mg daily, 6 received sustained-release nicardipine 100 to 150 mg daily, and one received intravenous nicardipine 120 mg daily. The peak milk concentration was 7.3 mcg/L (range 1.9 – 18.8), and the mean milk concentration was 4.4 mcg/L (range 1.3 – 13.8). Infants received an average of 0.073% of the weight-adjusted maternal oral dose and 0.14% of the weight-adjusted maternal intravenous dose.


In another study of seven women who received intravenous nicardipine for an average of 1.9 days in the immediate postpartum period as therapy for pre-eclampsia, 34 milk samples were obtained at unspecified times and nicardipine was undetectable (<5 mcg/L) in 82% of the samples. Four women who received 1 to 6.5 mg/hour of nicardipine had 6 milk samples with detectable nicardipine levels (range 5.1 to 18.5 mcg/L). The highest concentration of 18.5 mcg/L was found in a woman who received 5.5 mg/hour of nicardipine. The estimated maximum dose in a breastfed infant was <0.3 mcg daily or between 0.015 to 0.004% of the therapeutic dose in a 1 kg infant.



Pediatric Use


Safety and efficacy in patients under the age of 18 have not been established.



Use in the Elderly


The steady-state pharmacokinetics of nicardipine are similar in elderly hypertensive patients (>65 years) and young healthy adults.


Clinical studies of nicardipine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, use low initial doses in elderly patients, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.



ADVERSE EXPERIENCES


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.


Two hundred forty-four patients participated in two multicenter, double-blind, placebo-controlled trials of Cardene ® I.V. Adverse experiences were generally not serious and most were expected consequences of vasodilation. Adverse experiences occasionally required dosage adjustment. Therapy was discontinued in approximately 12% of patients, mainly due to hypotension, headache, and tachycardia.


The table below shows percentage of patients with adverse events where the rate is >3% more common on Cardene ® I.V. than placebo.

Sinus node dysfunction and myocardial infarction, which may be due to disease progression, have been seen in patients on chronic therapy with orally administered nicardipine.



Overdosage


Several overdosages with orally administered nicardipine have been reported. One adult patient allegedly ingested 600 mg of nicardipine [standard (immediate-release) capsules], and another patient, 2160 mg of the sustained-release formulation of nicardipine. Symptoms included marked hypotension, bradycardia, palpitations, flushing, drowsiness, confusion and slurred speech. All symptoms resolved without sequelae. An overdosage occurred in a one-year-old child who ingested half of the powder in a 30 mg nicardipine standard capsule. The child remained asymptomatic.


Based on results obtained in laboratory animals, lethal overdose may cause systemic hypotension, bradycardia (following initial tachycardia) and progressive atrioventricular conduction block. Reversible hepatic function abnormalities and sporadic focal hepatic necrosis were noted in some animal species receiving very large doses of nicardipine.


For treatment of overdosage, implement standard measures including monitoring of cardiac and respiratory functions. Position the patient so as to avoid cerebral anoxia. Use vasopressors for patients exhibiting profound hypotension.



Cardene Injection Dosage and Administration


Cardene ® I.V. is intended for intravenous use. Titrate dose to achieve the desired blood pressure reduction. Individualize dosage depending on the blood pressure to be obtained and the response of the patient.


The time course of blood pressure decrease is dependent on the initial rate of infusion and the frequency of dosage adjustment. With constant infusion, blood pressure begins to fall within minutes. It reaches about 50% of its ultimate decrease in about 45 minutes.



Preparation


WARNING: AMPULS MUST BE DILUTED BEFORE INFUSION


Dilution: Cardene ® I.V. is administered by slow continuous infusion at a CONCENTRATION OF 0.1 MG/ML. Each ampul (25 mg) should be diluted with 240 mL of compatible intravenous fluid (see below), resulting in 250 mL of solution at a concentration of 0.1 mg/mL.


Cardene ® I.V. has been found to be compatible and stable in glass or polyvinyl chloride containers for 24 hours at controlled room temperature with:


Dextrose (5%) Injection, USP

Dextrose (5%) and Sodium Chloride (0.45%) Injection, USP

Dextrose (5%) and Sodium Chloride (0.9%) Injection, USP

Dextrose (5%) with 40 mEq Potassium, USP

Sodium Chloride (0.45%) Injection, USP

Sodium Chloride (0.9%) Injection, USP


Cardene ® I.V. is NOT compatible with Sodium Bicarbonate (5%) Injection, USP or Lactated Ringer’s Injection, USP.


THE DILUTED SOLUTION IS STABLE FOR 24 HOURS AT ROOM TEMPERATURE.


Inspection: As with all parenteral drugs, Cardene ® I.V. should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Cardene ® I.V. is normally light yellow in color.



Dosage


Dosage as a Substitute for Oral Nicardipine Therapy


The intravenous infusion rate required to produce an average plasma concentration equivalent to a given oral dose at steady state is shown in the following table:


      Oral Cardene® Dose      Equivalent l.V. Infusion Rate

              20 mg q8h                        0.5 mg/hr = 5mL/hr

              30 mg q8h                        1.2 mg/hr = 12 mL/hr

              40 mg q8h                        2.2 mg/hr = 22 mL/hr


Dosage for Initiation of Therapy in a Patient not receiving oral nicardipine


Initiate therapy at 50 mL/hr (5.0 mg/hr). If desired blood pressure reduction is not achieved at this dose, the infusion rate may be increased by 25 mL/hr (2.5 mg/hr) every 5 minutes (for rapid titration) to 15 minutes (for gradual titration) up to a maximum of 150 mL/hr (15.0 mg/hr), until desired blood pressure reduction is achieved.


Following achievement of the blood pressure goal utilizing rapid titration, decrease the infusion rate to 30 mL/hr (3 mg/hr).



Drug Discontinuation and Transfer to Oral Antihypertensive Agents


Discontinuation of infusion is followed by a 50% offset action in about 30 minutes.


If treatment includes transfer to an oral antihypertensive agent other than oral nicardipine, initiate therapy upon discontinuation of Cardene ® I.V.


If oral nicardipine is to be used, administer the first dose 1 hour prior to discontinuation of the infusion.

HumaLog Mix 75/25 Vials


Pronunciation: IN-su-lin LIS-pro
Generic Name: Insulin Lispro Protamine/Insulin Lispro
Brand Name: HumaLog Mix 50/50 and HumaLog Mix 75/25


HumaLog Mix 75/25 Vials are used for:

Treating diabetes mellitus.


HumaLog Mix 75/25 Vials are a combination of an intermediate-acting and a fast-acting form of the hormone insulin. It works by helping your body to use sugar properly. This lowers the amount of glucose in the blood, which helps to treat diabetes.


Do NOT use HumaLog Mix 75/25 Vials if:


  • you are allergic to any ingredient in HumaLog Mix 75/25 Vials

  • you are having an episode of low blood sugar

Contact your doctor or health care provider right away if any of these apply to you.



Before using HumaLog Mix 75/25 Vials:


Some medical conditions may interact with HumaLog Mix 75/25 Vials. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you drink alcoholic beverages or smoke

  • if you have kidney or liver problems; nerve problems; adrenal, pituitary or thyroid problems; or diabetic ketoacidosis

  • if you use 3 or more insulin injections per day

  • if you are fasting, have high blood sodium levels, or are on a low salt diet

Some MEDICINES MAY INTERACT with HumaLog Mix 75/25 Vials. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Beta-blockers (eg, propranolol), clonidine, guanethidine, lithium, or reserpine because they may increase the risk of high or low blood sugar or may hide the signs and symptoms of low blood sugar, if it occurs

  • Angiotensin-converting (ACE) inhibitors (eg, enalapril), disopyramide, fenfluramine, fibrates (eg, clofibrate, gemfibrozil), fluoxetine, monoamine oxidase inhibitors (MAOIs) (eg, phenelzine), oral medicine for diabetes (eg, glipizide, metformin, nateglinide), pentamidine, propoxyphene, salicylates (eg, aspirin), somatostatin analogs (eg, octreotide), or sulfonamide antibiotics (eg, sulfamethoxazole) because the risk of low blood sugar may be increased

  • Corticosteroids (eg, prednisone), danazol, diuretics (eg, furosemide, hydrochlorothiazide), estrogen, hormonal contraceptives (eg, birth control pills), isoniazid, niacin, phenothiazines (eg, chlorpromazine), progesterones (eg, medroxyprogesterone), somatropin, sympathomimetics (eg, albuterol, epinephrine, terbutaline), or thyroid hormones (eg, levothyroxine) because they may decrease HumaLog Mix 75/25 Vials's effectiveness, resulting in high blood sugar

This may not be a complete list of all interactions that may occur. Ask your health care provider if HumaLog Mix 75/25 Vials may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.


How to use HumaLog Mix 75/25 Vials:


Use HumaLog Mix 75/25 Vials as directed by your doctor. Check the label on the medicine for exact dosing instructions.


  • An extra patient leaflet is available with HumaLog Mix 75/25 Vials. Talk to your pharmacist if you have questions about this information.

  • Use HumaLog Mix 75/25 Vials within 15 minutes before a meal, unless directed otherwise by your doctor.

  • If you will be using HumaLog Mix 75/25 Vials at home, a health care provider will teach you how to use it. Be sure you understand how to use HumaLog Mix 75/25 Vials. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.

  • Carefully rotate the vial as directed before each injection. This will ensure that the contents are evenly mixed. This combination insulin should look uniformly cloudy or milky.

  • Do not use HumaLog Mix 75/25 Vials if it contains particles or clumps, is discolored, or if the vial is cracked or damaged.

  • Do NOT dilute HumaLog Mix 75/25 Vials or mix it with other insulin. Do NOT use it in an insulin pump.

  • Use the proper technique taught to you by your doctor. Inject deep under the skin, NOT into a vein or muscle.

  • Injection sites within an injection area (abdomen, thigh, upper arm) must be rotated from one injection to the next.

  • Be sure you have purchased the correct insulin. Insulin comes in a variety of containers, including vials, cartridges, and pens. Make sure that you understand how to properly measure and prepare your dose. If you have any questions about measuring and preparing your dose, contact your doctor or pharmacist for information.

  • HumaLog Mix 75/25 Vials begins lowering blood sugar within minutes after an injection. The effect may last for up to 24 hours.

  • Keep this product, as well as syringes and needles, out of the reach of children and pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.

  • It is very important to follow your insulin regimen exactly. Do NOT miss any doses. Ask your doctor for specific instructions to follow in case you should ever miss a dose of insulin.

Ask your health care provider any questions you may have about how to use HumaLog Mix 75/25 Vials.



Important safety information:


  • HumaLog Mix 75/25 Vials may cause dizziness, drowsiness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use HumaLog Mix 75/25 Vials with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

  • Do not drink alcohol without discussing it with your doctor. Drinking alcohol may increase the risk of developing high or low blood sugar.

  • Do not use more than the recommended dose, use HumaLog Mix 75/25 Vials more often than prescribed, or change the type or dose of insulin you are using without checking with your doctor.

  • Any change of insulin should be made cautiously and only under medical supervision. Changes in purity, strength, brand (manufacturer), type (regular, NPH, lente), species (beef, pork, beef-pork, human), and/or method of manufacture may require a change in dose.

  • Illness, especially with nausea and vomiting, may cause your insulin requirements to change. Even if you are not eating, you will still require insulin. You and your doctor should establish a sick day plan to use in case of illness. When you are sick, test your blood/urine frequently and call your doctor as instructed.

  • Tell your doctor or dentist that you take HumaLog Mix 75/25 Vials before you receive any medical or dental care, emergency care, or surgery.

  • If you will be traveling across time zones, consult your doctor concerning adjustments in your insulin schedule.

  • Carry an ID card at all times that says you have diabetes.

  • An insulin reaction resulting from low blood sugar levels (hypoglycemia) may occur if you take too much insulin, skip a meal, or exercise too much. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.

  • Developing a fever or infection, eating significantly more than prescribed, or missing your dose of insulin may cause high blood sugar (hyperglycemia). High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If not treated, loss of consciousness, coma, or death may occur. If these symptoms occur, tell your doctor right away.

  • Check with your doctor if you notice a depression in the skin or skin thickening at the injection site. You may need to change your injection technique.

  • Proper diet, regular exercise, and regular testing of blood sugar are important for best results when using HumaLog Mix 75/25 Vials.

  • Lab tests, including fasting blood glucose levels and hemoglobin A1c levels, may be performed while you use HumaLog Mix 75/25 Vials. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

  • Use HumaLog Mix 75/25 Vials with caution in the ELDERLY; if low blood sugar occurs, it may be more difficult to recognize in these patients.

  • HumaLog Mix 75/25 Vials should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.

  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using HumaLog Mix 75/25 Vials while you are pregnant.

P4E1


Generic Name: epinephrine and pilocarpine ophthalmic (ep ih NEF rin and pie low CAR peen)

Brand Names: E-Pilo-1, E-Pilo-2, E-Pilo-4, E-Pilo-6, P1E1, P2E1, P3E1, P4E1, P6E1


What is P4E1 (epinephrine and pilocarpine ophthalmic)?

Epinephrine ophthalmic reduces congestion in the eye by constricting blood vessels in the eye. It also enlarges the pupil, and it reduces the amount of fluid in the eye in two ways: It reduces the production of fluid inside the eye, and it increases the amount of fluid that drains from the eye.


Pilocarpine ophthalmic also reduces pressure in the eye by increasing the amount of fluid that drains from the eye. In addition, pilocarpine causes the pupil to become smaller and reduces its response to light or dark conditions.


Together, epinephrine and pilocarpine are used to lower increased pressure in the eye that may be caused by conditions such as open-angle glaucoma and ocular (eye) hypertension (high pressure).

Epinephrine and pilocarpine ophthalmic is not commercially available in the United States.


Epinephrine and pilocarpine ophthalmic may also be used for purposes other than those listed in this medication guide.


What is the most important information I should know about P4E1 (epinephrine and pilocarpine ophthalmic)?


Contact your doctor immediately if you notice any decrease in vision or an increase in "floaters" in your visual field. Rarely, pilocarpine ophthalmic may cause retinal detachment. Retinal detachment can lead to blind spots, floaters in your visual field, and even blindness. Your doctor will want to check your retina before you use this medication to determine if you have an increased risk of retinal detachment.


Do not touch the dropper to any surface, including the eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in the eye.

Apply light pressure to the inside corner of the eye (near the nose) after each drop to prevent the fluid from draining down the tear duct.


Use caution when driving, operating machinery, or performing other hazardous activities. Epinephrine and pilocarpine ophthalmic may cause blurred or decreased night vision. If you experience blurred or decreased vision, avoid these activities.

What should I discuss with my healthcare provider before using P4E1 (epinephrine and pilocarpine ophthalmic)?


Epinephrine and pilocarpine ophthalmic should not be used to treat narrow- or shallow-angle glaucoma.


Rarely, pilocarpine ophthalmic may cause retinal detachment. Tell your doctor if you have any type of retinal disease, if you have had a retinal tear, if you are nearsighted, or if you have had cataract surgery. These conditions may increase the risk of retinal detachment.


Before using this medication, tell your doctor if you have



  • heart failure,




  • high or low blood pressure,




  • ever had a heart attack,




  • asthma,




  • a stomach ulcer or stomach spasms,




  • epilepsy,




  • hyperthyroidism (an overactive thyroid),




  • blockage of your urinary tract or difficulty urinating, or




  • Parkinson's disease.



You may not be able to use epinephrine and pilocarpine ophthalmic, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.


If you wear contact lenses, remove them before applying epinephrine and pilocarpine ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication.


It is not known whether epinephrine and pilocarpine ophthalmic will be harmful to an unborn baby. Do not use epinephrine and pilocarpine ophthalmic without first talking to your doctor if you are pregnant or could become pregnant during treatment. It is not known whether epinephrine and pilocarpine passes into breast milk. Do not use epinephrine and pilocarpine ophthalmic without first talking to your doctor if you are breast-feeding a baby.

How should I use P4E1 (epinephrine and pilocarpine ophthalmic)?


Use epinephrine and pilocarpine ophthalmic eye drops exactly as directed by your doctor. If you do not understand these instructions, ask your doctor, pharmacist, or nurse to explain them to you.


Wash your hands before and after using the eye drops.

If you wear contact lenses, remove them before applying epinephrine and pilocarpine ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication.


To apply the eye drops:



  • Tilt the head back slightly and pull down on the lower eyelid. Position the dropper above the eye. Look up and away from the dropper. Squeeze out a drop and close the eye. Apply gentle pressure to the inside corner of the eye (near the nose) for about 1 minute to prevent the liquid from draining down the tear duct. If you are using more than 1 drop in the same eye, repeat the process with about 5 minutes between drops. Repeat the process in the other eye if needed.



Epinephrine and pilocarpine ophthalmic is usually used once or twice a day. Follow your doctor's instructions.


Do not touch the dropper to any surface, including the eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in the eye. Do not use any eye drop that is discolored or has particles in it. Store epinephrine and pilocarpine ophthalmic at room temperature away from moisture and heat. Keep the bottle properly capped.

What happens if I miss a dose?


Apply the missed dose as soon as you remember. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and apply the next one as directed. Do not use a double dose of this medication.


What happens if I overdose?


The symptoms of an epinephrine and pilocarpine ophthalmic overdose are unknown. Sweating, nausea, vomiting, diarrhea, watering mouth, and tearing eyes may occur. If you suspect an overdose, or if the drops have been ingested, call an emergency room or poison control center for advice.


What should I avoid while using P4E1 (epinephrine and pilocarpine ophthalmic)?


Use caution when driving, operating machinery, or performing other hazardous activities. Epinephrine and pilocarpine ophthalmic may cause blurred or decreased night vision. If you experience blurred or decreased vision, avoid these activities. Do not touch the dropper to any surface, including your eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in your eye.

If you wear contact lenses, remove them before applying epinephrine and pilocarpine ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication.


Do not use other eye medications during treatment with epinephrine and pilocarpine ophthalmic except under the direction of your doctor.


P4E1 (epinephrine and pilocarpine ophthalmic) side effects


Contact your doctor immediately if you notice any decrease in vision or an increase in "floaters" in your visual field. Rarely, pilocarpine ophthalmic may cause retinal detachment. Retinal detachment can lead to blind spots, floaters in your visual field, and even blindness. Your doctor will want to check your retina before you use this medication to determine if you have an increased risk of retinal detachment.


If you experience any of the following serious side effects, stop using epinephrine and pilocarpine ophthalmic and seek emergency medical attention or contact your doctor immediately:

  • an allergic reaction (swelling of the lips, face, or tongue; difficulty breathing; shortness of breath; or hives);




  • high blood pressure (severe headache, blurred vision, or flushed skin); or

Folic Acid




Folic Acid Tablet USP

Folic Acid Description


Folic Acid, N-[p-[[(2-amino-4-hydroxy-6-pteridinyl) methyl]-amino]benzoyl]-L-glutamic acid, is a B complex vitamin containing a pteridine moiety linked by a methylene bridge to para-aminobenzoic acid, which is joined by a peptide linkage to glutamic acid. Conjugates of Folic Acid are present in a wide variety of foods, particularly liver, kidneys, yeast, and leafy green vegetables. Commercially available Folic Acid is prepared synthetically. Folic Acid occurs as a yellow or yellowish-orange crystalline powder and is very slightly soluble in water and insoluble in alcohol. Folic Acid is readily soluble in dilute solutions of alkali hydroxides and carbonates, and solutions of the drug may be prepared with the aid of sodium hydroxide or sodium carbonate, thereby forming the soluble sodium salt of Folic Acid (sodium folate). Aqueous solutions of Folic Acid are heat sensitive and rapidly decompose in the presence of light and/or riboflavin; solutions should be stored in a cool place protected from light.


The structural formula of Folic Acid is as follows:


C19H19N7O6 M.W. 441.40



Each tablet, for oral administration, contains 1 mg Folic Acid.


Folic Acid Tablets USP 1 mg contain the following inactive ingredients: microcrystalline cellulose, colloidal silicon dioxide, lactose monohydrate, sodium starch glycolate and stearic acid



Folic Acid - Clinical Pharmacology


Folic Acid acts on megaloblastic bone marrow to produce a normoblastic marrow.


In man, an exogenous source of folate is required for nucleoprotein synthesis and the maintenance of normal erythropoiesis. Folic Acid is the precursor of tetrahydroFolic Acid, which is involved as a cofactor for transformylation reactions in the biosynthesis of purines and thymidylates of nucleic acids. Impairment of thymidylate synthesis in patients with Folic Acid deficiency is thought to account for the defective deoxyribonucleic acid (DNA) synthesis that leads to megaloblast formation and megaloblastic and macrocytic anemias.


Folic Acid is absorbed rapidly from the small intestine, primarily from the proximal portion. Naturally occurring conjugated folates are reduced enzymatically to Folic Acid in the gastrointestinal tract prior to absorption. Folic Acid appears in the plasma approximately 15 to 30 minutes after an oral dose; peak levels are generally reached within 1 hour. After intravenous administration, the drug is rapidly cleared from the plasma. Cerebrospinal fluid levels of Folic Acid are several times greater than serum levels of the drug. Folic Acid is metabolized in the liver to 7,8-dihydroFolic Acid and eventually to 5,6,7,8-tetrahydroFolic Acid with the aid of reduced diphosphopyridine nucleotide (DPNH) and folate reductases. TetrahydroFolic Acid is linked in the N5 or N10 positions with formyl, hydroxymethyl, methyl, or formimino groups. N5-formyltetrahydroFolic Acid is leucovorin. TetrahydroFolic Acid derivatives are distributed to all body tissues but are stored primarily in the liver. Normal serum levels of total folate have been reported to be 5 to 15 ng/mL; normal cerebrospinal fluid levels are approximately 16 to 21 ng/mL. Normal erythrocyte folate levels have been reported to range from 175 to 316 ng/mL. In general, folate serum levels below 5 ng/mL indicate folate deficiency, and levels below 2 ng/mL usually result in megaloblastic anemia.


After a single oral dose of 100 mcg of Folic Acid in a limited number of normal adults, only a trace amount of the drug appeared in the urine. An oral dose of 5 mg in 1 study and a dose of 40 mcg/kg of body weight in another study resulted in approximately 50% of the dose appearing in the urine. After a single oral dose of 15 mg, up to 90% of the dose was recovered in the urine. A majority of the metabolic products appeared in the urine after 6 hours; excretion was generally complete within 24 hours. Small amounts of orally administered Folic Acid have also been recovered in the feces. Folic Acid is also excreted in the milk of lactating mothers.



Indications and Usage for Folic Acid


Folic Acid is effective in the treatment of megaloblastic anemias due to a deficiency of Folic Acid (as may be seen in tropical or nontropical sprue) and in anemias of nutritional origin, pregnancy, infancy, or childhood.



Contraindications


Folic Acid is contraindicated in patients who have shown previous intolerance to the drug.



Warnings


Administration of Folic Acid alone is improper therapy for pernicious anemia and other megaloblastic anemias in which vitamin B12 is deficient.



Precautions



General


Folic Acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurologic manifestations remain progressive.


There is a potential danger in administering Folic Acid to patients with undiagnosed anemia, since Folic Acid may obscure the diagnosis of pernicious anemia by alleviating the hematologic manifestations of the disease while allowing the neurologic complications to progress. This may result in severe nervous system damage before the correct diagnosis is made. Adequate doses of vitamin B12 may prevent, halt, or improve the neurologic changes caused by pernicious anemia.



Drug Interactions


There is evidence that the anticonvulsant action of phenytoin is antagonized by Folic Acid. A patient whose epilepsy is completely controlled by phenytoin may require increased doses to prevent convulsions if Folic Acid is given. Folate deficiency may result from increased loss of folate, as in renal dialysis and/or interference with metabolism (e.g., Folic Acid antagonists such as methotrexate); the administration of anticonvulsants, such as diphenylhydantoin, primidone, and barbiturates; alcohol consumption and, especially, alcoholic cirrhosis; and the administration of pyrimethamine and nitrofurantoin. False low serum and red cell folate levels may occur if the patient has been taking antibiotics, such as tetracycline, which suppress the growth of Lactobacillus casei.



Carcinogenesis, Mutagenesis, Impairment of Fertility


Long-term studies in animals to evaluate carcinogenic potential and studies to evaluate the mutagenic potential or effect on fertility have not been conducted.



Pregnancy


Teratogenic Effects


Pregnancy Category A


Folic Acid is usually indicated in the treatment of megaloblastic anemias of pregnancy. Folic Acid requirements are markedly increased during pregnancy, and deficiency will result in fetal damage (see INDICATIONS AND USAGE). Studies in pregnant women have not shown that Folic Acid increases the risk of fetal abnormalities if administered during pregnancy. If the drug is used during pregnancy, the possibility of fetal harm appears remote. Because studies cannot rule out the possibility of harm, however, Folic Acid should be used during pregnancy only if clearly needed.



Nursing Mothers


Folic Acid is excreted in the milk of lactating mothers. During lactation, Folic Acid requirements are markedly increased; however, amounts present in human milk are adequate to fulfill infant requirements, although supplementation may be needed in low-birth-weight infants, in those who are breast-fed by mothers with Folic Acid deficiency (50 mcg daily), or in those with infections or prolonged diarrhea.



Adverse Reactions


Allergic sensitization has been reported following both oral and parenteral administration of Folic Acid.


Folic Acid is relatively nontoxic in man. Rare instances of allergic responses to Folic Acid preparations have been reported and have included erythema, skin rash, itching, general malaise, and respiratory difficulty due to bronchospasm. One patient experienced symptoms suggesting anaphylaxis following injection of the drug. Gastrointestinal side effects, including anorexia, nausea, abdominal distention, flatulence, and a bitter or bad taste, have been reported in patients receiving 15 mg Folic Acid daily for 1 month. Other side effects reported in patients receiving 15 mg daily include altered sleep patterns, difficulty in concentrating, irritability, over activity, excitement, mental depression, confusion, and impaired judgment. Decreased vitamin B12 serum levels may occur in patients receiving prolonged Folic Acid therapy.


In an uncontrolled study, orally administered Folic Acid was reported to increase the incidence of seizures in some epileptic patients receiving phenobarbital, primidone, or diphenylhydantoin. Another investigator reported decreased diphenylhydantoin serum levels in folate-deficient patients receiving diphenylhydantoin who were treated with 5 mg or 15 mg of Folic Acid daily.



Overdosage


Except during pregnancy and lactation, Folic Acid should not be given in therapeutic doses greater than 0.4 mg daily until pernicious anemia has been ruled out. Patients with pernicious anemia receiving more than 0.4 mg of Folic Acid daily who are inadequately treated with vitamin B12 may show reversion of the hematologic parameters to normal, but neurologic manifestations due to vitamin B12 deficiency will progress. Doses of Folic Acid exceeding the Recommended Dietary Allowance (RDA) should not be included in multivitamin preparations; if therapeutic amounts are necessary, Folic Acid should be given separately.



Folic Acid Dosage and Administration


Oral administration is preferred. Although most patients with malabsorption cannot absorb food folates, they are able to absorb Folic Acid given orally. Parenteral administration is not advocated but may be necessary in some individuals (e.g., patients receiving parenteral or enteral alimentation). Doses greater than 0.1 mg should not be used unless anemia due to vitamin B12 deficiency has been ruled out or is being adequately treated with a cobalamin. Daily doses greater than 1 mg do not enhance the hematologic effect, and most of the excess is excreted unchanged in the urine.


The usual therapeutic dosage in adults and children (regardless of age) is up to 1 mg daily. Resistant cases may require larger doses.


When clinical symptoms have subsided and the blood picture has become normal, a daily maintenance level should be used, i.e., 0.1 mg for infants and up to 0.3 mg for children under 4 years of age, 0.4 mg for adults and children 4 or more years of age, and 0.8 mg for pregnant and lactating women, but never less than 0.1 mg/day. Patients should be kept under close supervision and adjustment of the maintenance level made if relapse appears imminent. In the presence of alcoholism, hemolytic anemia, anticonvulsant therapy, or chronic infection, the maintenance level may need to be increased.
