Atorvastatin, lovastatin, simvastatin, and rosuvastatin are metabolized by the CYP3A4 metabolic pathway. Fluvastatin is metabolized by CYP2C9. Pravastatin is not metabolized by the CYP P450 system.
Drug-drug:
- Risk of myopathy with lovastatin is ↑ by strong CYP3A4 inhibitors, including ketoconazole, itraconazole, posaconazole, voriconazole protease inhibitors, clarithromycin, erythromycin, nefazodone, and cobicistat-containing products; concurrent use contraindicated.
- Risk of myopathy with simvastatin is ↑ by cyclosporine, gemfibrozil, danazol, erythromycin, clarithromycin, protease inhibitors, nefazodone, ketoconazole, itraconazole, voriconazole, posaconazole, and cobicistat-containing products; concurrent use contraindicated.
- Risk of myopathy with pitavastatin is ↑ by cyclosporine; concurrent use contraindicated.
- Bioavailability and effectiveness may be ↓ by cholestyramine and colestipol.

- Risk of myopathy with pitavastatin is ↑ by erythromycin, rifampin, colchicine, fibrates, or large doses of niacin; avoid concurrent use with gemfibrozil; use ↓ doses with erythromycin, rifampin, and niacin.
- Risk of myopathy with pravastatin is ↑ by cyclosporine, fibrates, colchicine, erythromycin, clarithromycin, azithromycin, or large doses of niacin; avoid concurrent use with gemfibrozil; consider lower dose with niacin.
- Risk of myopathy with rosuvastatin is ↑ by atazanavir/ritonavir, capmatinib, colchicine, cyclosporine, darolutamide, dasabuvir/ombitasvir/paritaprevir/ritonavir, elbasvir/grazoprevir, enasidenib, febuxostat, fibrates, fostamatinib, glecaprevir/pibrentasvir, lopinavir/ritonavir, niacin (large doses), regorafenib, sofosbuvir/velpatasvir, tafamidis, teriflunomide, and ticagrelor; avoid concurrent use with gemfibrozil; use ↓ doses with atazanavir/ritonavir, capmatinib, cyclosporine, darolutamide, dasabuvir/ombitasvir/paritaprevir/ritonavir, elbasvir/grazoprevir, enasidenib, fostamatinib, glecaprevir/pibrentasvir, lopinavir/ritonavir, regorafenib, sofosbuvir/velpatasvir, tafamidis, and teriflunomide.
