Malegra 100 mg contains sildenafil citrate, a medication used to treat erectile dysfunction (ED) in adult men. It works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain a firm erection suitable for sexual activity. Sildenafil belongs to a class of medicines called PDE5 inhibitors. It works by blocking the PDE5 enzyme, which allows levels of cGMP to increase. This relaxes blood vessels in the penile tissue and improves circulation. https://www.genericday.com/malegra-100-mg.html
