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).

Sildenafil and vardenafil inhibit the enzyme PDE-5 , which has the effect of dilating blood vessels near the penis and relaxing the muscles in the tissue called the corpus cavernosum inside the penis.

As a result, blood vessels dilate and muscles relax, allowing more blood to flow into the corpora cavernosa within the penis, promoting an erection.
