概要

Rifampin is a strong inducer of CYP enzymes and P-glycoprotein and substantially lowers exposure to velpatasvir, voxilaprevir and sofosbuvir. This can cause loss of antiviral efficacy and treatment failure.

この相互作用をわかりやすく説明すると

Rifampin and Sofosbuvir-velpatasvir-voxilaprevir 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.

エビデンスレベル: High

なぜ起こるのか

Rifampin induces CYP3A4, CYP2B6, CYP2C8 and P-glycoprotein, increasing clearance and decreasing absorption of the antiviral components.

対処法

Do not use together; complete or replace rifampin with an alternative (such as rifabutin if appropriate, with expert advice) before starting therapy.
