Viagra has achieved a great popularity over the years as being among the most effective remedies for erectile dysfunction (ED) in men, which is the leading cause of poor sexual life and psychological issues related to sex. Erectile dysfunction (ED) has psychological roots, but it manifests itself through the inability to achieve a satisfactory erection that would facilitate sexual intercourse. While the psychological problems take a long time to solve through relaxation techniques, psychotherapy and other interventions aimed to increasing a man’s confidence in his sexual capacity and diminish anxiety, pharmaceutical remedies such as Viagra have been successfully utilized to eliminate the physical symptoms of erectile dysfunction and restore the male sexual ability. Once the physical signs of ED are dramatically reduced, the psychological recovery comes considerably faster. Viagra has been formulated from the active substance called Sildenafil, which is a pharmaceutical substance that is classified as a phosphodiesterase enzyme type 5 inhibitor (PDE5 inhibitor). Viagra (Sildenafil) have also been successfully prescribed and used by patients who have other diseases where its blood vessel dilation properties may be useful, such as pulmonary hypertension. However, ED remains the major reason Viagra is prescribed to millions of men around the world, and it successfully achieved its mission over the years.

How does Viagra (Sildenafil) function in the male body to achieve the recovery of the sexual drive and erection?
An erection starts with a signal originating in the brain regions that process sexual stimuli, from where it travels to the penis through nerves. The nerve endings communicate with the specialized blood vessels in the penis, which are able to dilate considerably and receive great amounts of blood, through nitric oxide (NO) as a chemical messenger. NO stimulates the production and accumulation of cyclic GMP, which is the main chemical compound that works with the blood vessels and causes them to dilate significantly. The widening of the blood vessels is what causes the cavernous chambers to fill with increasing quantities of blood until the penis exhibits an erection, which facilitates the healthy sexual act. The ED symptoms may be linked to the activity of the phosphodiesterase type 5 enzyme (PDE5), which is normally present in all men. It is responsible for the breakdown of cyclic GMP when the amounts are excessive, which typically ends the erection. While the PDE5 enzyme is a normal and healthy presence that allows for the regulation of cyclic GMP levels, its activity may facilitate erectile dysfunction symptoms in some men. Viagra (Sildenafil) was formulated to inhibit the phosphodiesterase type 5 enzyme in a manner that allows increasing amounts of cyclic GMP to become available for a proper erectile response. The potential side effects of Viagra administration are usually minor and rare, consisting of possible headaches or abdominal discomfort. However, you are encouraged to report any unpleasant effects that may occur after taking Viagra and discuss ED treatment options with your doctor.
