The active ingredient in Vigora 100 mg, Sildenafil, is an essential component in treating erectile dysfunction. When a man is ****ually stimulated, the body releases nitric oxide, leading to the relaxation of blood vessels in the ****. This relaxation allows increased blood flow, resulting in an erection. However, in cases of ED, the PDE5 enzyme breaks down cyclic guanosine monophosphate (cGMP), which disrupts the process. Sildenafil inhibits PDE5, enhancing the accumulation of cGMP and facilitating the natural process of achieving an erection.
