How does Zhewitra-20 (Vardenafil) work:

Zhewitra-20 (Vardenafil) is used to treating impotence (erectile dysfunction). This engorgement occurs when the blood vessels delivering blood to the penis increase in size and increase the delivery of blood to the penis. Zhewitra-20 (Vardenafil) acts by blocking an enzyme called phosphodiesterase-5, or PDE-5. This helps the smooth muscles in the penis to relax, which effectively increases blood flow. Zhewitra-20 (Vardenafil) will not give a man an erection spontaneously, it will only help a man to get an erection if he is sexually stimulated.
