Malegra Pro 100 mg is a medication primarily used to treat erectile dysfunction (ED). It contains sildenafil citrate, which is the same active ingredient found in Viagra. Sildenafil is a PDE5 inhibitor, and it works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. When a man is sexually stimulated, sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down a substance that helps relax the blood vessels in the penis.
