The active ingredient in Malegra 50 Mg, sildenafil citrate, is a PDE5 inhibitor. It works by relaxing the blood vessels in the penis, enabling increased blood flow during sexual arousal. As a result, it helps men achieve a firm erection. Unlike some other ED treatments, sildenafil only works in the presence of sexual stimulation. It has a fast onset of action, typically within 30-60 minutes after ingestion, and can last up to 4-6 hours.
