When a man gets an erection, certain processes happen in his organism. With sexual stimulation, the nitric oxide releases. This substance activates an enzyme cGMP which is responsible for the muscle relaxation in the penis. Once the muscles are relaxed, the blood starts flowing into the penis. The penis expands and an erection occurs.
In a person who experiences ED or impotence the erectile process is impaired. The negative effect is caused by an enzyme called PDE type 5 which affects cGMP and does not allow muscle relaxation and blood inflow. Viagra inhibits PDE type 5 and thus facilitates the erectile process.
The medicine works only with sexual stimulation as the nitric oxide releases only when a man is sexually excited.
Vitro studies of sildenafil have shown that it is selective for PDE type 5, but may have certain effect on other PDEs if used in higher doses. Thus the use of Viagra in the right dose not higher than recommended is important.
