Sildenafil Citrate, the active ingredient in Kamagra Polo, is identical to the active ingredient in the brand-name Viagra product. Sildenafil Citrate belongs to a class of pharmaceuticals known as PDE-5 inhibitors, and it is one of the medications in this class. The PDE-5 enzyme (which is responsible for degrading cGMP) is blocked in Kamagra Polo tablets to increase the relaxation and vasodilation of the smooth muscles of the genitals (the widening of blood vessels).
