Aurogra is a medication used for the treatment of erectile dysfunction. The action mechanism of Aurogra lies in the chemical content of this drug. The main ingredient is sildenafil citrate. This drug blocks PDE5. The condition of erectile failure arises when there is minimum or no blood flow in the male organ. This occurs due to PDE5 enzymes. These enzymes decrease the elasticity of arteries that transport blood to the reproductive organ of man. Aurogra prevents the enzymes to do the same, thereby maintain smoother blood flow at the time of intimacy. This drug is effective for nearly four hours after consumption.
