Malegra 50 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate as the active ingredient, the same substance found in Viagra. Sildenafil is a PDE5 inhibitor that helps to increase blood flow to the pill during sexual stimulation, allowing men with ED to achieve and maintain an erection. Sildenafil works by blocking the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cGMP (cyclic guanosine monophosphate). https://www.genericday.com/malegra-50-mg.html
