Zenegra 100 Mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate 100 mg, which belongs to a group of medicines called PDE5 inhibitors. Sildenafil helps increase blood flow to the penis during sexual stimulation, supporting the ability to achieve and maintain an erection. Zenegra 100 Mg works by blocking the PDE5 enzyme, which helps maintain higher levels of cyclic guanosine monophosphate (cGMP). This relaxes blood vessels and improves blood circulation in the penile area during sexual arousal. https://www.genericday.com/zenegra-100-mg.html
