KAMAGRA-100 Chewable Tabs KAMAGRA-100 Chewable Tabs contain Sildenafil Citrate formulated as chewable tablets for rapid oral absorption without requiring water. Sildenafil is a potent selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). During sexual stimulation, nitric oxide (NO) is released in the corpus cavernosum, activating guanylate cyclase and increasing intracellular levels of cGMP. Sildenafil inhibits PDE5, preventing the enzymatic degradation of cGMP in the vascular smooth muscle of the penis and facilitating sustained cGMP accumulation. Increased cGMP levels induce smooth muscle relaxation and arterial vasodilation within the erectile tissue, enhancing blood flow to the corpus cavernosum and enabling a natural erectile response. KAMAGRA-100 Chewable Tabs are packaged as a combipack containing 4 distinct fruit flavors and are indicated for the treatment of erectile dysfunction (ED) in adult males.
