Tadact 20 mg contains tadalafil, which is a medication primarily used to treat erectile dysfunction (ED) in men. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to sildenafil (Viagra) and vardenafil (Levitra), which works by increasing blood flow to the penis during sexual stimulation, helping men to achieve and maintain an erection.
