Résumé
Tadalafil strongly potentiates nitrate-induced vasodilation, which can cause severe and possibly fatal hypotension. Its long half-life means the interaction persists for days.
Ce que signifie cette interaction, en termes simples
Nitroglycerin po and Tadalafil 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.
Pourquoi elle survient
Nitrate-derived nitric oxide raises cGMP while tadalafil blocks PDE5 degradation, causing excessive vasodilation.
Conduite à tenir
Do not co-administer; avoid nitrates for at least 48 hours after a tadalafil dose. Use non-nitrate options and monitor closely if a nitrate is needed urgently.
