Malegra is a prescription medicine used to treat erectile dysfunction (ED) in adult men. Its active ingredient is sildenafil citrate, a PDE5 inhibitor that improves blood flow to the pill during sexual stimulation, helping achieve and maintain an erection. Sildenafil relaxes the smooth muscles in blood vessels, especially in the genital area. This increases blood flow during sexual arousal. It does not increase sexual desire and only works when there is sexual stimulation. https://www.genericday.com/malegra.html
