Tadalista 20 is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by increasing blood flow to the penis, allowing men to achieve and maintain an erection when sexually aroused. Tadalista 20 is specifically prescribed for men who have difficulty getting or maintaining an erection sufficient for sexual intercourse. It does not enhance sexual desire but helps with the physiological processes necessary for an erection.
