Malegra 100 mg, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. This effect is achieved by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By blocking PDE5, sildenafil enhances the effects of nitric oxide—a natural chemical the body produces to relax muscles in the penis and increase blood flow.
