Tadalista is a brand of medication that contains the active ingredient Tadalafil. It is primarily used to treat erectile dysfunction (ED) in men. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis when a man is sexually aroused, enabling him to achieve and maintain an erection. Tadalista is prescribed to men who have difficulty getting or maintaining an erection sufficient for sexual activity. It is not a cure for ED but can help improve erectile function when used as directed.
