Viagra 50mg tablet is better known as the Vgr 50 blue pill. It is an effective medicine used for the treatment of erectile dysfunction (ED) in men. Erectile dysfunction is a condition where a man is unable to achieve or maintain an erection adequate for sexual intercourse. The mechanism of action of the Vgr 50 tablet involves the inhibition of the PDE5 enzyme, which leads to increased blood flow to the penis during sexual stimulation.
