Full Prescribing Info
Atorvastatin calcium.
Each film-coated tablet contains Atorvastatin (as Calcium) 20 mg or 40 mg.
Pharmacology: Pharmacokinetics: Atorvastatin is rapidly absorbed from the gastro-intestinal tract. It has low absolute bioavailability of about 12% due to presystemic clearance in the gastro-intestinal mucosa and/or first-pass metabolism in the liver, its primary site of action. Atorvastatin is metabolized by cytochrome P450 3A4 to a number of compounds which are also active inhibitors of HMG-CoA reductase. The mean plasma elimination half-life of atorvastatin is about 14 hours although the half-life of inhibitory activity for HMG-CoA reductase is approxiamately 20 to 30 hours due to the contribution of the active metabolites. It is 98% bound to plasma proteins. Atorvastatin is excreted as metabolites, primarily in the bile.
Treatment of hypercholesterolaemias and combined (mixed) hyperlipidaemia.
Dosage/Direction for Use
Initial dose is 10 or 20 mg once daily which may be adjusted at intervals of 4 weeks up to a maximum of 80 mg daily.
Special Precautions
Atorvastatin should not be given to patients with acute liver disease or unexplained persistent raised serum-aminotransferase concentrations or to those with porphyria. It should be avoided during pregnancy since there is a possibility that it could interfere with fetal sterol synthesis. It should be used with caution in patients with severe renal impairment.
