Malegra is a prescription medicine used to treat erectile dysfunction (ED) in adult men. It contains Sildenafil, a well-known drug that helps improve blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection. Sildenafil in Malegra works by blocking the enzyme Phosphodiesterase type 5. This enzyme normally breaks down cGMP, a chemical that relaxes smooth muscles in blood vessels. When PDE5 is inhibited, cGMP levels increase, leading to relaxation of blood vessels and improved blood flow to erectile tissues during sexual arousal. This supports a stronger and more sustained erection, but only when sexual stimulation is present.
