Résumé

Tipranavir, given with ritonavir, inhibits CYP3A4 and P-glycoprotein and can substantially increase colchicine concentrations. This raises the risk of severe or fatal colchicine toxicity, especially in renal or hepatic impairment.

Ce que signifie cette interaction, en termes simples

Colchicine 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.

Colchicine belongs to Genitourinary; Tipranavir belongs to Anti Virals.

Niveau de preuve: Moderate

Pourquoi elle survient

Ritonavir-boosted tipranavir inhibits CYP3A4 and P-glycoprotein, decreasing colchicine clearance.

Conduite à tenir

Avoid in patients with renal or hepatic impairment. Otherwise use an alternative if possible, or reduce the colchicine dose per labeling and monitor closely for toxicity.
