The active ingredient in Kamagra Chewable, sildenafil, is a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme found in the smooth muscles of the penis, and it plays a key role in the breakdown of cyclic GMP, a molecule that helps relax these muscles and increase blood flow. When a man is ****ually aroused, nitric oxide is released in the penis, triggering the production of cyclic GMP. Sildenafil works by inhibiting PDE5, which allows cyclic GMP to accumulate and promote sustained blood flow to the penis, resulting in an erection.
