Amdova® is a combination product containing Amlodipine Besilate BP equivalent to 5 mg Amlodipine, a calcium channel blocker and Atorvastatin calcium INN equivalent to 10 mg Atorvastatin, a statin (HMG-CoA reductase inhibitor). Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Atorvastatin calcium is a synthetic lipid-lowering agent. It is an inhibitor of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA). This enzyme catalyzes the conversion of HMG-CoA to mevatonate, an early and rate limiting step in the synthesis of cholesterol.
Amlodipine: The usual initial antihypertensive oral dose is 5 mg once daily with a maximum dose of 10 mg once daily. Elderly individuals or patients with hepatic insufficiency may be started on 2.5 mg once daily dose and this dose may be used when adding Amlodipine to other antihypertensive therapy. Dosage should be adjusted according to each patient’s need. The recommended dose for chronic stable or vasospastic angina is 5-10 mg, with the lower dose suggested in the elderly and in patients with hepatic insufficiency.
Atorvastatin: Adults: The patient should be placed on a standard cholesterol-lowering diet before receiving Atorvastatin and should continue on this diet during treatment with Atorvastatin Hypercholesterolemia (Heterozygous Familial and Nonfamilial) and Mixed Dyslipidemia (Fredrickson Types IIa and IIb): The recommended starting dose of Atorvastatin is 10 mg daily. The dosage range 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. Homozygous Familial Hypercholesterolemia: The dosage of Atorvastatin in patients with homozygous FH is 10 to 80 mg daily. Patients with renal insufficiency: Renal disease has no influence on the plasma concentrations or lipid effects of Atorvastatin; thus no adjustment of dose is required. Hemodialysis is not expected to significantly enhance the clearance of Atorvastatin since the drug is extensively bound to plasma proteins. Patients with hepatic dysfunction: In patients with moderate to severe hepatic dysfunction, the therapeutic response to Atorvastatin is unaffected but exposure to the drug is greatly increased.
