概要

Phenobarbital is an inducer of CYP3A4 and P-gp and can markedly lower concentrations of sofosbuvir, velpatasvir and voxilaprevir. This can lead to HCV treatment failure.

この相互作用をわかりやすく説明すると

Phenobarbital 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

Phenobarbital induces CYP3A4, CYP2B6 and P-gp, which increases clearance of the HCV drugs.

対処法

Do not coadminister; switch to a non-inducing anticonvulsant, or defer HCV treatment.
