How does Viagra 100 MG Tablet Work?

Viagra is a PDE-5 inhibitor that contains Sildenafil as its active ingredient. The medicine works through the following mechanism:

Cyclic Guanosine Monophosphate (or cGMP) is a cyclic nucleotide derived from guanosine triphosphate, which is responsible for signal transducing.
Phosphodiesterase – 5 (PDE-5) is an enzyme that is responsible for regulating the localization, duration, and amplitude of cyclic nucleotide signaling within subcellular domains.
Sildenafil, being Phosphodiesterase – 5 Inhibitor, inhibits PDE-5 so as to block the degradative action of cGMP.
cGMP diffuses into the vascular smooth muscle cells adjacent to the endothelium. Here, it stimulates a cGMP-dependent protein kinase that activates another enzyme known as myosin light chain phosphatase. This, in turn, dephosphorylates the myosin light chains to relax the smooth muscles present in the walls of blood vessels in the penis.
When used to treat pulmonary arterial hypertension, this medicine simply works by decreasing the blood pressure in the pulmonary blood vessels.
