The neurotransmitter responsible for erections is nitric oxide (NO). Nitric oxide plays a crucial role in the process of achieving and maintaining an erection by relaxing the smooth muscles in the walls of blood vessels in the penis, allowing them to dilate and increase blood flow to the erectile tissues.

Cenforce 100 Mg contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the action of the enzyme PDE5, which normally breaks down cyclic guanosine monophosphate (cGMP). cGMP is a signaling molecule that helps to relax the smooth muscles and widen the blood vessels in the penis, leading to increased blood flow and erection.

Therefore, while Cenforce 100 mg doesn't directly affect the production or release of nitric oxide, it enhances the effects of nitric oxide by preventing the breakdown of cGMP, leading to improved erectile function.
