What is a pde5 inhibitor

Ruben_miller02 Jan, 2025Health

PDE-5 inhibitors are a class of medications commonly used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). These drugs work by inhibiting the enzyme phosphodiesterase type 5 (PDE-5), which plays a role in the breakdown of cyclic guanosine monophosphate (cGMP). This molecule helps relax the smooth muscles and allows for better blood flow, particularly in the blood vessels of the penis or the lungs.
