Silvitra ( https://www.topqualityrx.com/silvitra.aspx ) is a medically proven remedy that is composed of a medication known as Vardenafil, which is approved by the Food and Drug Administration (FDA). Pharmacologically, Vardenafil is a medicine that is classified under a group of drugs called PDE5-inhibitor. This medicine looks after promoting an adequate amount of blood in a penile organ for erection, regardless of cause and medical condition.    

The body’s naturally secreting enzyme known as PDE5 (phosphodiesterase type five) is reduced after the oral administration of Silvitra (Vardenafil). This action further increases the levels of cyclic Guanosine Monophosphate and Nitric Oxide that elevate the blood flow in the spongy erectile tissues. This allows the reproductive tool to experience rigidity for a longer duration so men can complete the act of copulation satisfactorily. The effect of this drug is for nearly five hours; hence, he can experience an erection after very sexual stimulation and perform coition for a sufficient amount of time.
