Penegra 100 mg is a prescription medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual arousal, helping to achieve and maintain an erection. Unlike some other ED treatments, Penegra does not induce sexual desire; it enhances the physical response when sexual stimulation occurs.
