Tadalafil, the active ingredient in Tadalista, inhibits the enzyme phosphodiesterase type 5 (PDE5). This enzyme restricts blood flow to the penis. By blocking PDE5, tadalafil helps relax the muscles in the blood vessels of the penis, leading to improved blood flow and an erection in response to sexual stimulation. Tadalista is known for its long-lasting effects, with the medication remaining active for up to 36 hours, which is why it's often referred to as the "weekend pill."
