Penegra 50 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by relaxing blood vessels and increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection suitable for sexual activity. The 50 mg dose is considered a standard or intermediate dose, often prescribed when a lower dose (25 mg) is not sufficient.
