Sildenafil citrate, the active ingredient in Kamagra Chewable tablets, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5) in the corpus cavernosum of the penis. This inhibition leads to an increase in the levels of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscles and increases blood flow to the penis, resulting in an erection. https://www.genericday.com/kamagra-chewable-tablet.html
