It works by inhibiting the actions of PDE type-5 enzyme and improves blood flow towards the private organs of men to the penile and relaxes blood vessels in the penile, cause erection during intimacy session. This medication helps men to get erection only if he is sexually stimulated.

Mechanism of action:

The physiologic mechanism of erection is a natural process which involves the release of nitric oxide in the corpus cavernosum at the time of sexual stimulation. Nitric oxide helps in the activation the enzyme called guanylate cyclase, which result in the increase level of cyclic guanosine monophosphate (cGMP) and provide smooth muscle relaxation in the corpus cavernosum that are located on the either side of the penile and allow the flow of blood to it. Penegra enhance the effect of nitric oxide by stopping the activity of phosphodiesterase type-5, which is accountable for degradation of cGMP in corpus cavernosum. Sexual stimulation will release nitric oxide; inhibition of PDE-5 by Penegra will increase in the amount of cGMP in the corpus cavernosum and result in smooth muscle relaxation, flow of blood to the corpus cavernosum. In the absence of sexual stimulation, sildenafil won't work.
