Tadagra 20 mg is a tablet that contains tadalafil 20 mg, a phosphodiesterase‑5 (PDE5) inhibitor used mainly to treat erectile dysfunction (ED) in adult men. It works by relaxing blood vessels in the pill so that blood flow increases, helping a man achieve and maintain an erection when sexually stimulated. The medicine typically starts working within about 30–60 minutes and its effect can last up to 36 hours, which is longer than many sildenafil‑based ED drugs. https://www.genericday.com/tadagra-20-mg.html
