Pharmacology
Sotatercept-csrk is an activin signaling inhibitor that binds to activin A and other TGF-beta superfamily ligands, improving the balance between pro-proliferative and anti-proliferative signaling to modulate vascular proliferation in pulmonary arterial hypertension.
Sildenafil is a selective inhibitor of cGMP-specific PDE-5 in pulmonary vascular smooth muscle; by blocking PDE-5-mediated cGMP degradation, it elevates cGMP levels resulting in relaxation and vasodilation of the pulmonary vascular bed in patients with PAH.
