Vigora 100 mg is a prescription medication used to treat erectile dysfunction (ED). The active ingredient in Vigora is Sildenafil Citrate, which is also found in other well-known ED treatments. Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Its primary function is to enhance blood flow to the penis, helping achieve and maintain an erection during sexual activity. When you are sexually aroused, the body releases nitric oxide, which activates an enzyme called guanylate cyclase.
