Tadalista is a prescription medication used to treat erectile dysfunction (ED) in men. Its active ingredient is tadalafil, a long-acting phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation. Tadalafil in Tadalista inhibits the PDE5 enzyme, allowing for prolonged blood vessel relaxation and improved erectile response when aroused.
