Penegra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps increase blood flow to the penis during sexual stimulation. This improved blood flow supports the ability to achieve and maintain a firm erection. The 100 mg dose is typically prescribed for men who do not respond adequately to lower doses (such as 25 mg or 50 mg). It should be taken about 30 to 60 minutes before sexual activity, and its effects can last for up to 4–5 hours.
