概要

Nitrates increase cGMP via nitric oxide and sildenafil blocks its breakdown, causing profound vasodilation. This can lead to severe, potentially fatal hypotension.

この相互作用をわかりやすく説明すると

Amyl nitrite and Sildenafil 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

Do not use together. Nitrates should be avoided for at least 24 hours after sildenafil.
