Résumé

Tipranavir, given with ritonavir, strongly inhibits CYP3A4 and can substantially increase eletriptan concentrations. This raises the risk of excessive vasoconstriction and cardiovascular events.

Ce que signifie cette interaction, en termes simples

Eletriptan and Tipranavir 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.

Eletriptan belongs to Central Nervous System; Tipranavir belongs to Anti Virals.

Niveau de preuve: Moderate

Pourquoi elle survient

Inhibition of CYP3A4 metabolism of eletriptan, with ritonavir-boosting enhancing the effect.

Conduite à tenir

Avoid eletriptan within 72 hours of tipranavir/ritonavir. Use an alternative acute migraine therapy with less CYP3A4 dependence.
