Tadagra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, tadalafil increases blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. Tadagra 20 mg is specifically indicated for the treatment of erectile dysfunction in men, which is the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It is not intended for use in women or individuals under 18 years of age.
