Resumo
Lonafarnib is a sensitive CYP3A4 substrate, and diltiazem as a moderate CYP3A4 inhibitor can substantially increase its exposure. This raises the risk of lonafarnib toxicity, including gastrointestinal effects, renal and hepatic toxicity, and QT-related concerns. Labeling advises against use with moderate or strong CYP3A4 inhibitors.
O que esta interação significa em palavras simples
Diltiazem and Lonafarnib 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.
Diltiazem belongs to Cardiovascular; Lonafarnib belongs to Miscellaneous.
Por que acontece
Diltiazem inhibits CYP3A4, reducing the metabolic clearance of lonafarnib.
O que fazer
Avoid the combination and select a non-CYP3A4-inhibiting alternative to diltiazem. If unavoidable, follow labeling dose-reduction guidance and monitor closely for toxicity.
