Tadalista 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a PDE5 inhibitor, which works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Tadalafil, the active ingredient in Tadalista 40 mg, works by inhibiting the PDE5 enzyme that breaks down cGMP (a molecule that helps relax smooth muscle tissue in the penis). https://www.flatmeds.com/product/tadalista-40-mg/
