What is the working mechanism of the generic viagra medication?
The basic ingredient that is the Sildenafil citrate inhibits the work of the PDE5 inhibitors. These PDE 5 enzymes actually reduce the CGMP enzymes in the blood. Once these PDE5 inhibitors are blocked the brain allows the release of nitric oxide in the blood and this, in turn, boosts the growth of the cGMP enzymes. This then relaxes the blood vessels and the blood reaches the penis. Once the penis is filled with blood erection occurs.
