The main active ingredient of Viagra is sildenafil, a Phosphodiesterase type-5 (PDE5) inhibitor. PDE5 inhibitors function to stop the PDE5 enzyme from regulating the blood molecules, which may make it more difficult for you to get and maintain an erection. By inhibiting and delaying PDE5, viagra is able to relax blood vessel walls and facilitate easier blood flow in order to initiate and maintain an erection. visit at bestonlinepharmacy
