Vidalista is a brand name for a medication primarily used to treat erectile dysfunction (ED) in men. Its active ingredient is Tadalafil, a PDE-5 inhibitor, which is the same active ingredient found in Cialis. Tadalafil works by increasing blood flow to the penis, allowing men to achieve and maintain an erection when sexually aroused. Tadalafil, the active ingredient in Vidalista, works by inhibiting the phosphodiesterase type-5 (PDE-5) enzyme. PDE-5 breaks down cyclic GMP (cGMP), which is a molecule that helps relax the smooth muscles and dilates the blood vessels in the penis.
