Ultimo aggiornamento
Per operatori sanitari — solo a scopo di riferimento. Questa pagina è una sintesi breve, non è un parere medico e non sostituisce il RCP ufficiale né il giudizio clinico. Verificare sempre prima di prescrivere o dispensare.
Il contenuto clinico di questa pagina è disponibile solo in inglese.
Sintesi
Tadalafil markedly enhances the blood pressure lowering effect of rectal nitroglycerin. Severe hypotension may occur and the risk lasts well beyond the dose because of tadalafil's long half-life.
Cosa significa questa interazione in parole semplici
Nitroglycerin rectal 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.
Perché avviene
Additive cGMP-mediated vasodilation from nitric oxide donation and PDE5 inhibition.
Cosa fare
Avoid combination; keep nitrates at least 48 hours away from tadalafil. Use non-nitrate therapy within that window.
