Tadalista 5 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a PDE5 inhibitor that helps improve blood flow to the penis by relaxing blood vessels. This increased blood circulation makes it easier to achieve and maintain an erection during sexual activity. Tadalista 5 mg works by enhancing the effects of cGMP, a chemical that controls how blood vessels open and close. When a man is sexually aroused, nitric oxide is released, triggering cGMP production and allowing more blood to flow into the penis, resulting in an erection. This medicine only works when the user is sexually stimulated.
