Vidalista 5 mg tablets work primarily through the active ingredient Tadalafil, a potent phosphodiesterase type 5 (PDE5) inhibitor. In the treatment of erectile dysfunction (ED), Tadalafil increases blood flow to the penis by inhibiting the PDE5 enzyme, which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP).
Elevated levels of cGMP lead to the relaxation of smooth muscle cells in the blood vessel walls, allowing for increased blood flow into the penile tissues. This process facilitates the achievement and maintenance of an erection when sexually stimulated.
