概要
Atazanavir inhibits CYP3A4 and raises amlodipine exposure, and boosted regimens with ritonavir or cobicistat also raise atorvastatin exposure. This increases the risk of hypotension, edema and statin myopathy.
この相互作用をわかりやすく説明すると
Amlodipine-atorvastatin and Atazanavir 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; Atazanavir belongs to Anti Virals.
なぜ起こるのか
Inhibition of CYP3A4 (and OATP with boosters) reduces clearance of amlodipine and atorvastatin.
対処法
Use a reduced amlodipine dose, with separate agents, and monitor blood pressure and ECG for PR prolongation. Keep atorvastatin at the lowest effective dose and watch for muscle symptoms.
