Cenforce 100 mg works by improving blood flow to the penis, which helps treat erectile dysfunction (ED). The active ingredient in Cenforce 100 mg is sildenafil citrate, a type of phosphodiesterase type 5 (PDE5) inhibitor. Here’s how it works:

1. Inhibition of PDE5: Sildenafil blocks the enzyme PDE5, which is responsible for breaking down cyclic GMP (cGMP). This enzyme is found in the smooth muscle cells of blood vessels in the penis.
2. Increased cGMP Levels: When PDE5 is inhibited, the levels of cGMP increase. This molecule plays a crucial role in relaxing the smooth muscles of the blood vessels, allowing them to dilate.
3. Improved Blood Flow: The dilation of blood vessels increases blood flow to the penis during sexual stimulation. This helps achieve and maintain an erection that is firm enough for sexual activity.
4. Effectiveness: Cenforce 100 mg is effective only when there is sexual arousal. It doesn’t automatically cause an erection but enhances the natural response to sexual stimulation.

By improving blood flow to the penis, Cenforce 100 mg helps men with ED experience improved erectile function and better overall sexual performance.
