Penegra 50 mg contains Sildenafil citrate, a medication used to treat erectile dysfunction (ED) in men. Its main action occurs by relaxing the blood vessels in the penis during sexual stimulation. Normally, sexual arousal triggers the release of a chemical called nitric oxide, which increases levels of cyclic GMP (cGMP) in the smooth muscles of the penis. This causes the blood vessels to dilate, allowing blood to fill the erectile tissue and produce an erection.
Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down cGMP. By blocking PDE5, PENEGRA 50 MG allows cGMP to accumulate, prolonging the dilation of blood vessels and supporting a firm erection.
The medication does not cause an erection on its own; sexual stimulation is required for it to work. After taking Penegra 50 mg, effects usually appear within 30–60 minutes and can last 3–5 hours.
Common side effects include headache, flushing, indigestion, nasal congestion, dizziness, and visual changes. Rarely, it may cause prolonged erections or sudden vision or hearing loss, requiring immediate medical attention.
In summary, Penegra 50 mg enhances natural erectile response by increasing blood flow to the penis during sexual arousal, helping men with ED achieve and maintain an erection.
