Malegra is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate, the same ingredient found in medications like Viagra. Sildenafil works by relaxing the muscles in the blood vessels and increasing blood flow to the penis, helping men achieve and maintain an erection during sexual activity. Malegra works by inhibiting the enzyme PDE5, which normally breaks down cGMP, a substance that helps relax smooth muscles and dilate blood vessels in the penis.
