Penegra 50 mg, which contains the active ingredient Sildenafil, is a medication commonly used to treat erectile dysfunction (ED) by enhancing blood flow to the penis. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE-5), which can lead to increased blood flow into the penile tissues when sexual arousal occurs. This increased blood flow helps men achieve and maintain an erection during sexual activity.
