Amlodipine Besylate And Atorvastatin Calcium

Description

11 DESCRIPTION Amlodipine besylate and atorvastatin calcium tablets combine the calcium channel blocker amlodipine besylate USP with the HMG CoA-reductase inhibitor atorvastatin calcium. The amlodipine besylate USP is chemically described as 3-ethyl-5-methyl (4RS)-2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate benzenesulphonate. Its molecular formula is C 20 H 25 ClN 2 O 5

What Is Amlodipine Besylate And Atorvastatin Calcium Used For?

1 INDICATIONS AND USAGE Amlodipine besylate and atorvastatin calcium tablets are indicated in patients for whom treatment with both amlodipine and atorvastatin is appropriate. Amlodipine Amlodipine besylate and atorvastatin calcium tablets are a combination of amlodipine besylate, a calcium channel blocker, and atorvastatin calcium, a HMG CoA-reductase inhibitor, indicated in patients for whom treatment with both amlodipine and atorvastatin is appropriate. Amlodipine is indicated for the treatment of hypertension, to lower blood pressure (1.1). Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. Amlodipine is indicated for the treatment of Coronary Artery Disease (1.2). Atorvastatin is indicated as an adjunct therapy to diet for prevention of cardiovascular disease (1.3) and hyperlipidemia (1.4). 1.1 Hypertension Amlodipine is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including amlodipine. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive...

Dosage and Administration

2 DOSAGE AND ADMINISTRATION Amlodipine besylate and atorvastatin calcium Dosage of amlodipine besylate and atorvastatin calcium must be individualized on the basis of both effectiveness and tolerance for each individual component in the treatment of hypertension/angina and hyperlipidemia. Select doses of amlodipine and atorvastatin independently. Amlodipine besylate and atorvastatin calcium may be substituted for its individually titrated components. Patients may be given the equivalent dose of amlodipine besylate and atorvastatin calcium or a dose of amlodipine besylate and atorvastatin calcium with increased amounts of amlodipine, atorvastatin, or both for additional antianginal effects, blood pressure lowering, or lipid-lowering effect. Amlodipine besylate and atorvastatin calcium may be used to provide additional therapy for patients already on one of its components. Amlodipine besylate and atorvastatin calcium may be used to initiate treatment in patients with hyperlipidemia and either hypertension or angina. Amlodipine The usual initial antihypertensive oral dose of amlodipine is 5 mg once daily, and the maximum dose is 10 mg once daily. Pediatric (age > 6 years), small adult, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg once daily and this dose may be used when adding amlodipine to other antihypertensive therapy. Adjust dosage according to blood pressure goals. In general, wait 7 to 14 days between titration steps. Titration may proceed more rapidly, however, if clinically warranted, provided the patient is assessed frequently. Angina: The recommended dose of amlodipine for chronic stable or vasospastic angina is 5 to 10 mg, with the lower dose suggested in the elderly and in patients with hepatic insufficiency. Most patients will require 10 mg for adequate effect. Coronary Artery Disease : The recommended dose range of amlodipine for patients with CAD is 5 to 10 mg once daily. In clinical studies, the majority of patients required 10 mg [see Clinical Studies ( 14.4 ) ]. Pediatrics: The effective antihypertensive oral dose of amlodipine in pediatric patients ages 6 to 17 years is 2.5 mg to 5 mg once daily. Doses in excess of 5 mg daily have not been studied in pediatric patients [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14.1 ) ]. Atorvastatin (Hyperlipidemia) Hyperlipidemia and Mixed Dyslipidemia: The recommended starting dose of atorvastatin is 10 or 20 mg once daily. Patients who require a large reduction in LDL-C (more than 45%) may be started at 40 mg once daily. The dosage range of atorvastatin is 10 to 80 mg once daily. Atorvastatin can be administered as a single dose at any time of the day, with or without food. The starting dose and maintenance doses of atorvastatin should be individualized according to patient characteristics such as goal of therapy and response. After initiation and/or upon titration of atorvastatin, lipid levels should be analyzed within 2 to 4...

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: Myopathy and Rhabdomyolysis [see Warnings and Precautions ( 5.1 ) ] Liver enzyme abnormalities [see Warnings and Precautions ( 5.3 ) ] Most common adverse reaction (3% greater than placebo) to amlodipine is edema ( 6.1 ). Most common adverse reactions leading to atorvastatin discontinuation were myalgia and diarrhea ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy’s Laboratories, Inc. at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience 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. Amlodipine besylate and atorvastatin calcium Amlodipine besylate and atorvastatin calcium has been evaluated for safety in 1,092 patients in double-blind placebo-controlled studies treated for co-morbid hypertension and dyslipidemia. In general, treatment with amlodipine besylate and atorvastatin calcium was well tolerated. For the most part, adverse reactions have been mild or moderate in severity. In clinical trials with amlodipine besylate and atorvastatin calcium, no adverse reactions peculiar to this combination have been observed. Adverse reactions are similar in terms of nature, severity, and frequency to those reported previously with amlodipine and atorvastatin. The following information is based on the clinical experience with amlodipine and atorvastatin. Amlodipine Amlodipine has been evaluated for safety in more than 11,000 patients in U.S. and foreign clinical trials. In general, treatment with amlodipine was well tolerated at doses up to 10 mg daily. Most adverse reactions reported during therapy with amlodipine were of mild or moderate severity. In controlled clinical trials directly comparing amlodipine (N=1,730) at doses up to 10 mg to placebo (N=1,250), discontinuation of amlodipine because of adverse reactions was required in only about 1.5% of patients and was not significantly different from placebo (about 1%). The most commonly reported side effects more frequent than placebo are dizziness and edema. The incidence (%) of side effects that occurred in a dose-related manner are as follows: 2.5 mg N=275 Amlodipine 5 mg N=296 10 mg N=268 Placebo N=520 Edema 1.8 3 10.8 0.6 Dizziness 1.1 3.4 3.4 1.5 Flushing 0.7 1.4 2.6 0 Palpitations 0.7 1.4 4.5 0.6 Other adverse reactions that were not clearly dose related but were reported at an incidence greater than 1% in placebo-controlled clinical trials include the following: Amlodipine (%) (N=1730) Placebo (%) (N=1250) Fatigue 4.5 2.8 Nausea 2.9 1.9 Abdominal Pain 1.6 0.3 Somnolence 1.4 0.6 Edema, flushing, palpitations, and somnolence appear to be more common in women than in men. The following events occurred in <1% but >0.1% of patients treated with amlodipine in controlled clinical trials or under conditions of open trials or marketing experience where a causal relationship is uncertain; they are listed to alert the physician to a possible relationship: Cardiovascular: arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, peripheral ischemia, syncope, tachycardia, vasculitis. Central and Peripheral Nervous System: hypoesthesia, neuropathy peripheral, paresthesia, tremor, vertigo. Gastrointestinal: anorexia, constipation, dysphagia, diarrhea, flatulence, pancreatitis, vomiting, gingival hyperplasia. General: allergic reaction, asthenia, 2 back pain, hot flushes, malaise, pain, rigors, weight gain, weight decrease. Musculoskeletal System: arthralgia, arthrosis, muscle cramps, 2 myalgia. Psychiatric: sexual dysfunction (male 2 and female), insomnia, nervousness, depression, abnormal dreams, anxiety, depersonalization. Respiratory System: dyspnea, 2...

Drug Interactions

7 DRUG INTERACTIONS Data from a drug-drug interaction study involving 10 mg of amlodipine and 80 mg of atorvastatin in healthy subjects indicate that the pharmacokinetics of amlodipine are not altered when the drugs are co-administered. The effect of amlodipine on the pharmacokinetics of atorvastatin showed no effect on the C max : 91% (90% confidence interval: 80 to 103%), but the AUC of atorvastatin increased by 18% (90% confidence interval: 109 to 127%) in the presence of amlodipine, which is not clinically meaningful. No drug interaction studies have been conducted with amlodipine besylate and atorvastatin calcium and other drugs, although studies have been conducted in the individual amlodipine and atorvastatin components, as described below: Amlodipine Increased Risk of Myopathy and Rhabdomyolysis ( 2 , 5.1 , 7.3 , 12.3 ) Cyclosporine, tipranavir plus ritonavir, glecaprevir plus pibrentasvir Avoid atorvastatin Clarithromycin, itraconazole, saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir, elbasvir plus grazoprevir,letermovir Do not exceed 20 mg atorvastatin daily Nelfinavir Do not exceed 40 mg atorvastatin daily Lopinavir plus ritonavir, simeprevir, fibric acid derivatives, erythromycin, azole antifungals, lipid-modifying doses of niacin, colchicine Consider the risk/benefit of concomitant use with atorvastatin Other Lipid-Lowering Medications: Increased risk of myopathy (7) . Rifampin should be simultaneously co-administered with atorvastatin ( 7.4 ). Oral Contraceptives: Norethindrone and ethinyl estradiol may be increased ( 7.5 ). Digoxin: Patients should be monitored appropriately ( 7.5 ). 7.1 Impact of Other Drugs on Amlodipine CYP3A Inhibitors Co-administration with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction. Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment [see Clinical Pharmacology ( 12.3 ) ]. CYP3A Inducers No information is available on the quantitative effects of CYP3A inducers on amlodipine. Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers. Sildenafil Monitor for hypotension when sildenafil is co-administered with amlodipine [see Clinical Pharmacology ( 12.2 ) ]. 7.2 Impact of Amlodipine on Other Drugs Immunosuppressants Amlodipine may increase the systemic exposure of cyclosporine or tacrolimus when co-administered. Frequent monitoring of trough blood levels of cyclosporine and tacrolimus is recommended and adjust the dose when appropriate [see Clinical Pharmacology ( 12.3 ) ]. Atorvastatin The risk of myopathy during treatment with statins is increased with concurrent administration of fibric acid derivatives, lipid-modifying doses of niacin, cyclosporine, or strong CYP3A4 inhibitors (e.g., clarithromycin, HIV and HCV protease inhibitors, and itraconazole)...

Contraindications

4 CONTRAINDICATIONS

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Amlodipine besylate and atorvastatin calcium tablets are contraindicated in women who are pregnant. Atorvastatin Atorvastatin is contraindicated for use in pregnant women since safety in pregnant women has not been established and there is no apparent benefit of lipid lowering drugs during pregnancy. Because HMG-CoA reductase inhibitors decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, atorvastatin may cause fetal harm when administered to a pregnant woman. Amlodipine besylate and atorvastatin calcium tablets should be discontinued as soon as pregnancy is recognized [see Contraindications ( 4 ) ]. Limited published data on the use of atorvastatin are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage. In animal reproduction studies in rats and rabbits there was no evidence of embryo-fetal toxicity or congenital malformations at doses up to 30 and 20 times, respectively, the human exposure at the MRHD of 80 mg, based on body surface area (mg/m 2 ). In rats administered atorvastatin during gestation and lactation, decreased postnatal growth and development was observed at doses ≥6 times the MRHD ( see Data ). Amlodipine The limited available data based on post-marketing reports with amlodipine use in pregnant women are not sufficient to inform a drug-associated risk for major birth defects and miscarriage. There are risks to the mother and fetus associated with poorly controlled hypertension in pregnancy ( see Clinical Considerations ). In animal reproduction studies, there was no evidence of adverse developmental effects when pregnant rats and rabbits were treated orally with amlodipine maleate during organogenesis at doses approximately 10 and 20 times MRHD, respectively. However for rats, litter size was significantly decreased (by about 50%) and the number of intrauterine deaths was significantly increased (about...

8.3 Females and Males of Reproductive Potential Contraception Atorvastatin may cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with amlodipine besylate and atorvastatin calcium [see Use in Specific Populations ( 8.1 )] .

Overdosage

10 OVERDOSAGE There is no information on overdosage with amlodipine besylate and atorvastatin calcium in humans. Amlodipine Overdosage might be expected to cause excessive peripheral vasodilation with marked hypotension and possibly a reflex tachycardia. In humans, experience with intentional overdosage of amlodipine is limited. Single oral doses of amlodipine maleate equivalent to 40 mg amlodipine/kg and 100 mg amlodipine/kg in mice and rats, respectively, caused deaths. Single oral amlodipine maleate doses equivalent to 4 or more mg amlodipine/kg or higher in dogs (11 or more times the MRHD on a mg/m 2 basis) caused a marked peripheral vasodilation and hypotension. If overdose should occur with amlodipine, initiate active cardiac and respiratory monitoring. Perform frequent blood pressure measurements. Should hypotension occur,provide cardiovascular support including elevation of the extremities and administration of fluids. If hypotension remains unresponsive to these conservative measures, consider administration of vasopressors (such as phenylephrine) with specific attention to circulating volume and urine output. As amlodipine is highly protein bound, hemodialysis is not likely to be of benefit. Atorvastatin There is no specific treatment for atorvastatin overdosage. In the event of an overdose, the patient should be treated symptomatically, and supportive measures instituted as required. Because of extensive drug binding to plasma proteins, hemodialysis is not expected to significantly enhance atorvastatin clearance.
