Tadalista 20 mg is a generic version of tadalafil, primarily used to treat erectile dysfunction (ED) in men. Manufactured by Fortune Healthcare, it functions by enhancing blood flow to the penis during sexual arousal, facilitating the achievement and maintenance of an erection. Tadalafil, the active ingredient in Tadalista, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the smooth muscles in the blood vessels of the penis, allowing increased blood flow during sexual stimulation, thereby facilitating an erection.
