Men with erectile dysfunction can be cured of their condition by taking silagra online, which relaxes the smooth muscles of the blood vessels and enhances blood flow in the anatomy. During intercourse, a man's erection depends on his body for two to three hours. The chemical phosphodiesterase type 5 is suppressed by the sildenafil citrate salt found in Silagra.  The PDE5 enzyme also degrades cyclic GMP, a chemical messenger.  Moreover, by relaxing the smooth artery muscle walls, this message usually causes the phallus' arteries to enlarge.  Additionally, this exercise increases the volume of blood in the leg, resulting in a firmer erection.  The arteries stay dilated for a considerable amount of time since the tablet also inhibits the PDE-5 enzyme.
