Résumé
Cobicistat is a strong CYP3A4 inhibitor and also inhibits OATP1B1/1B3 and P-gp. It can substantially increase exposure to amlodipine and atorvastatin, raising risks of hypotension, edema and statin myopathy.
Ce que signifie cette interaction, en termes simples
Amlodipine-atorvastatin and Cobicistat can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Amlodipine-atorvastatin belongs to Cardiovascular; Cobicistat belongs to Miscellaneous.
Pourquoi elle survient
Strong CYP3A4 and transporter inhibition by cobicistat reduces clearance of both amlodipine and atorvastatin.
Conduite à tenir
Use a lower amlodipine dose with blood pressure monitoring, and limit atorvastatin to the lowest effective dose per labeling, or choose a statin with less interaction such as rosuvastatin or pravastatin at low dose.
