概要
Darunavir, particularly when boosted, inhibits CYP3A4 and increases avanafil exposure. This raises the risk of marked hypotension, syncope, visual effects and priapism.
この相互作用をわかりやすく説明すると
Avanafil and Darunavir are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Avanafil belongs to Genitourinary; Darunavir belongs to Anti Virals.
なぜ起こるのか
CYP3A4 inhibition reduces first-pass and systemic metabolism of avanafil.
対処法
Avoid avanafil with darunavir regimens; consider another agent for erectile dysfunction with dose-limited, monitored use.
