Tadarise 10 Tablet works by inhibiting the action of the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis. Increased levels of cGMP lead to relaxation of the smooth muscles and dilation of the blood vessels in the penis, resulting in improved blood flow and the ability to achieve and maintain an erection.
