Suhagra 50MG contains Sildenafil which belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It is used to treat adult men with erectile dysfunction, also known as impotence. It happens when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Erectile dysfunction (ED) is the inability of men to attain and maintain an erect penis with sufficient rigidity to allow sexual intercourse. Sildenafil 50mg Tablets works by helping to relax the blood vessels in the penis, allowing blood to flow into the penis when you get sexually excited.
