 Amlodipine/Atorvastatin (Caduet)
Atorvastatin inhibits HMG-CoA reductase, which is the rate limiting enzyme in the liver that converts HMG-CoA to mevalonate, a precursor of cholesterol.
Amlodipine is converted to inactive metabolites (90%) in the liver, while atorvastatin is hepatically metabolized via the CYP3A4 enzyme into active metabolites, which is responsible for 70% of the circulating inhibitory activity of HMG-CoA reductase.
Atorvastatin is a known CYP3A4 inhibitor, thus increased effects occur with concurrent administration of cyclosporine, fibrates, niacin, erythromycin, and azole antifungals.

Consequently, for a patient with such a reaction to atorvastatin and for whom the lipid-lowering effects of an HMG-CoA-reductase inhibitor are necessary, other statins could be cautiously used.
