Résumé

Strong CYP3A4 inducers markedly lower nirmatrelvir concentrations, risking loss of antiviral efficacy against SARS-CoV-2 and resistance. Labeling contraindicates the combination with inducers.

Ce que signifie cette interaction, en termes simples

Enzalutamide and Nirmatrelvir 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.

Enzalutamide belongs to Endocrine; Nirmatrelvir belongs to Anti Virals.

Niveau de preuve: High

Pourquoi elle survient

Enzalutamide induces CYP3A4, accelerating nirmatrelvir clearance.

Conduite à tenir

Do not use together; consider an alternative COVID-19 therapy such as remdesivir. Induction persists after stopping enzalutamide, so allow a washout before starting nirmatrelvir.
