Viagra Sildenafil belongs to a group of medicines that delay the enzymes (phosphodiesterases or PDE) from working too quickly. Viagra Sildenafil acts as a PDE type-5 inhibitor. Viagra Sldenafil helps in achieving erection via a complex chain of events, involving signals from the nervous system and the release of chemical messengers within the tissues of the penis.
cGMP, one of the chemical messengers released by Viagra Sildenafil, causes the blood vessels in the penis to widen by relaxing a thin layer of muscle found in the blood vessel walls. This allows more blood to enter the penis, which ultimately results in a rigid erection. cGMP is normally broken down by another chemical in the body called phosphodiesterase type 5. Viagra Sildenafil works by preventing the action of phosphodiesterase type 5, thus stopping the breakdown of cGMP. This means that the blood vessels remain dilated for a longer time, improving blood flow to the penis and maintaining an erection. However, Viagra Sildenafil is not an aphrodisiac and it does not increase your sex drive.
Viagra Sildenafil is not affected by race, age or duration of erectile dysfunction.Viagra has been effective in a broad range of patients with erectile dysfunction, including those with chronic illness (such as MS), a history of coronary artery disease, hypertension, other cardiac disease, peripheral vascular disease, type 1 or 2 diabetes mellitus, mental depression, spina bifida, and spinal cord injury.
