Tadalista CT 20 mg contains Tadalafil, which works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 plays a role in regulating blood flow in the penis by breaking down a substance called cGMP. This substance is essential for relaxing the smooth muscles and widening the blood vessels in the penis during sexual arousal. When PDE5 is inhibited by Tadalafil, cGMP levels remain elevated, leading to increased blood flow and enabling an erection in response to sexual stimulation.
