Zenegra 50 mg is a medication that contains sildenafil citrate, which is the active ingredient in popular erectile dysfunction (ED) treatments like Viagra. Zenegra 50 mg works by increasing blood flow to the penis, helping men with ED achieve and maintain an erection during sexual activity. Sildenafil, the active ingredient, is a PDE5 inhibitor. It works by blocking the enzyme phosphodiesterase type 5 (PDE5), which helps relax the blood vessels in the penis. This results in increased blood flow, facilitating an erection when combined with sexual arousal.
