Viamax 25mg Tablet

Uses of Viamax 25mg Tablet

• Improves blood flow and oxygen supply to the penis

How does Viamax 25mg Tablet work?

Viamax 25mg Tablet works by inhibiting specific enzymes known as PDE5, which would otherwise restrict blood flow to the penis. By doing so, it promotes the relaxation of the blood vessels that supply the penis, leading to increased blood flow and improved oxygen supply. This mechanism ultimately helps in achieving and maintaining an erection.

Pharmacology

Sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor, combats impotence by blocking the actions of cyclic Guanosine Monophosphate (cGMP) degradation. By inhibiting PDE5, which is responsible for breaking down cGMP in the corpus cavernosum, Sildenafil promotes smooth muscle relaxation and increased blood flow. This enhances the effects of nitric oxide (NO), ultimately aiding in the treatment of erectile dysfunction.
