Biological Activity

Riociguat is an oral stimulator of soluble guanylate cyclase (sGC) used in the treatment of pulmonary hypertension.

In Vitro

Riocigua stimulates the recombinant sGC concentration dependently from 0.1 to 100 μM with a two-fold to 73-fold effect by an NO-independent but haem-dependent mechanism[1]. Riociguat inhibits platelet function in washed platelets but not in whole blood, and exerts no direct effects on contractility and relaxation of cardiac myocytes[2].

In Vivo

Riociguat (10 mg/kg/d, p.o.) partially reverses the pulmonary arterial hypertension, the right heart hypertrophy and the structural remodelling of the lung vasculature in chronic treatment of hypoxic mice and MCT-injected rats[1].
