How does Vidalista selectively inhibit phosphodiesterase type 5 (PDE5) in the corpus cavernosum?
Vidalista, also known as Tadalafil, selectively inhibits phosphodiesterase type 5 (PDE5) in the corpus cavernosum by specifically targeting this enzyme. PDE5 is responsible for breaking down cyclic guanosine monophosphate (cGMP), which plays a crucial role in regulating blood flow to the penis. When PDE5 is inhibited, cGMP levels increase, leading to smooth muscle relaxation and vasodilation in the corpus cavernosum, which enhances blood flow into the penis and facilitates an erection.
