Resumo
Riociguat combined with a PDE5 inhibitor such as tadalafil produces additive systemic vasodilation and symptomatic hypotension. In a pulmonary hypertension trial this combination showed no favorable benefit and raised safety concerns, and labeling prohibits it.
O que esta interação significa em palavras simples
Riociguat 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.
Riociguat belongs to Cardiovascular; Tadalafil belongs to Genitourinary.
Por que acontece
Riociguat stimulates soluble guanylate cyclase to produce cGMP while tadalafil prevents its breakdown, causing additive vasodilation.
