Maxgun Sublingual Spray contains sildenafil citrate, which belongs to a class of medicines known as phosphodiesterase type 5 (PDE-5) inhibitors. Its mechanism of action involves a series of physiological processes that occur naturally during sexual arousal.
Sexual stimulation leads to the release of nitric oxide (NO) from nerve endings and endothelial cells in the penile tissues. Nitric oxide activates the enzyme guanylate cyclase, which increases the production of cyclic guanosine monophosphate (cGMP).
cGMP plays a crucial role by relaxing the smooth muscles within the blood vessel walls of the penis. This relaxation causes vasodilation, or widening of the blood vessels, allowing increased blood flow into the erectile tissues, particularly the corpus cavernosum.
Under normal circumstances, the enzyme PDE-5 breaks down cGMP, which reduces blood flow and ends the erection. Sildenafil citrate inhibits the PDE-5 enzyme, preventing the breakdown of cGMP. As a result, cGMP levels remain elevated, smooth muscle relaxation is maintained, and blood flow to the penile tissues continues.
With ongoing sexual stimulation, this sustained blood flow helps achieve and maintain an erection suitable for sexual activity. Once sexual stimulation ends, cGMP levels gradually decrease, and the erection subsides naturally.
