Effects of Silvitra

Sildenafil and vardenafil, the main ingredients in Silvitra, work by suppressing 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).
