Malegra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. Sildenafil (the active ingredient in Malegra 100 mg) is a PDE5 inhibitor. PDE5 is an enzyme found in the smooth muscles of the penis that breaks down cGMP, a molecule that relaxes the smooth muscles and allows increased blood flow.
