Fildena 150mg  inhibits a PDE-5 enzyme that helps prevent the absence of cGMP caused by the PDE-5 enzyme. This medication helps relax the constricted blood vessels around the genitals when a man is successfully s*xually aroused and his body releases nitric oxide. It causes enough blood flow to complete and maintain a rigid erection for satisfaction and pleasure in a full orgasm session for erectile dysfunction.Most of the time, doctors recommend that you take the Fildena tablet in the right amount for an hour before having s*xual intercourse. If patients feel like taking the p*ll, they can take it anywhere.
