About
Cenforce 100 mg contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. When a man is sensually aroused, the body releases nitric oxide into the penile tissues, which activates an enzyme called cGMP. This enzyme causes the blood vessels in the male organ to dilate, allowing more blood to flow into the area and generating an erection. PDE5 is an enzyme that breaks down cGMP, containing the blood vessels from dilating and making it difficult for a man to attain or sustain an erection.
