اس تعامل کا آسان لفظوں میں مطلب

Clarithromycin and Ivacaftor 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.

شواہد کی سطح: Moderate

ایسا کیوں ہوتا ہے

Clarithromycin is a strong CYP3A4 inhibitor that reduces the metabolism of ivacaftor, a sensitive CYP3A substrate.

Reduce ivacaftor to the labeled dose for use with strong CYP3A inhibitors (a reduced frequency, such as once or twice weekly depending on the formulation and age). Consider azithromycin as an alternative macrolide with minimal CYP3A inhibition.
