概要

Griseofulvin may considerably lower lapatinib exposure, which could compromise anticancer efficacy. Lapatinib is a CYP3A4 substrate whose levels fall markedly with inducers.

この相互作用をわかりやすく説明すると

Griseofulvin and Lapatinib 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.

Griseofulvin belongs to Anti Fungals; Lapatinib belongs to Oncology.

エビデンスレベル: Moderate

なぜ起こるのか

Griseofulvin-mediated CYP3A4 induction increases lapatinib clearance.

対処法

Prefer a non-inducing antifungal. If unavoidable, lapatinib dose escalation as per labeling for strong inducers should be considered with close monitoring of response and toxicity.
