Zenegra 100 Mg is a medication designed to treat erectile dysfunction by improving blood flow to the penis during sexual stimulation. It contains sildenafil citrate, a potent vasodilator that enhances erectile function by inhibiting the enzyme phosphodiesterase type 5 (PDE5), thus promoting the release of nitric oxide in the corpus cavernosum of the penis. This mechanism of action facilitates smooth muscle relaxation and increased blood flow, resulting in a firm and lasting erection.
