Tadalista 20mg is a medication primarily used to treat erectile dysfunction (ED) in men, a condition characterized by the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. The active ingredient in Tadalista is Tadalafil, a potent and long-acting phosphodiesterase type 5 (PDE5) inhibitor, which works by enhancing blood flow to the penis during sexual stimulation. Tadalista 20mg does not increase sexual desire or act as an aphrodisiac—it only works in response to sexual arousal.
