概要

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.

この相互作用をわかりやすく説明すると

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.

エビデンスレベル: High

なぜ起こるのか

Additive cGMP-mediated vasodilation from nitric oxide donation and PDE5 inhibition.

対処法

Avoid combination; keep nitrates at least 48 hours away from tadalafil. Use non-nitrate therapy within that window.
