Zenegra 50 mg is a medication that contains Sildenafil Citrate, which is the same active ingredient found in Viagra. It is primarily used to treat erectile dysfunction (ED) in men. By improving blood flow to the penis, Zenegra helps men achieve and maintain an erection when sexually stimulated. Sildenafil is a PDE5 inhibitor, which works by blocking the enzyme PDE5 that restricts blood flow to the penis. This action allows for increased blood flow, making it easier to achieve and maintain an erection when sexually aroused. https://www.genericday.com/zenegra-50-mg.html
