Vidalista 20 mg belongs to the class of drugs known as PDE 5 inhibitors. The Tadalafil in it works by blocking the PDE-5 enzyme, so blood may flow freely to the penis.
The cGMP enzyme, responsible for the constriction and dilation of blood vessels, is destroyed by PDE 5. This is because the tadalafil in Vidalista 20 prevents PDE 5 from doing its job, thereby preventing cGMP degradation. Therefore, nitric oxide levels are increased, and the body is better able to synthesise cGMP. This ensures that the penis receives adequate blood supply. As blood flow to the penis rises, pressure is generated. Because of this, erections will occur.
