Effects of Zevitra 40mg
Vardenafil, the main ingredient in Zhewitra, works by inhibiting PDE-5 (phosphodiesterase type 5), an enzyme that inhibits erections.
An enzyme called PDE-5 breaks down cyclic guanosine monophosphate, which is necessary for erection.
When cyclic guanosine monophosphate is degraded, an erection cannot occur, a condition known as ED (erectile dysfunction).
