Viagra Professional (Sildenafil) is an enhanced formula of the most popular drug that is utilized by men who are suffering from symptoms of sexual disorders in general, and erectile dysfunction (ED) specifically. Sildenafil is the prototype drug that belongs to the PDE5 blocker medication family (phosphodiesterase type 5 inhibitors), and its biochemical structure and pharmaceutical function is very similar to other drugs in this group, such as Tadalafil or Avanafil. Viagra Professional has gained a huge popularity and recognition among male ED sufferers when the effects of the PDE5 enzyme were discovered and studied pharmaceutically. This enzyme is present in the penis, but may also be found in considerable amounts in the lungs, which is why Viagra Professional is sometimes prescribed off label as drug treatment for the symptoms of pulmonary hypertension due to its ability to widen and relax the blood vessels in the lungs.
Viagra Professional (Sildenafil) is also prescribed on a less frequent basis for females with sexual disorders and problems of sexual arousal, and it works in such cases through an enhancement of the blood flow in the pelvic region. After intake in the form of the pill, which is the classical form of Viagra Professional administration, it starts working in about 30 minutes and the effectiveness lasts for up to five hours, averaging about three hours of beneficial physiological effects in terms of a better erection.

How does Viagra Professional function in the human body to restore the normal physiologic response of a man to achieve an erection?
The brain will transmit a nerve signal after sexual arousal, which will be received by the blood vessels in the penis through a release of nitric oxide (NO), which functions as a chemical messenger between the nerves and the blood vessels. An enzyme is activated, and high amounts of cyclic GMP are produced. Cyclic GMP is the central compound in the chain of events leading to a healthy erection since it directly interacts with the muscles in the walls of the blood vessels, causing them to relax, which translates into a widening of the the blood vessels. This blood vessel dilation is what determines the erection, and makes a healthy sexual act possible. Unfortunately, the PDE5 enzyme quickly intervenes and destroys high quantities of cGMP, which ends the erectile response.
However, through the administration of Viagra Professional, men suffering from ED can experience a more potent and prolonged erection through the inhibition of the PDE5 enzyme, which makes cyclic GMP increasingly available for blood vessel dilation in the penis. Side effects are mostly mild, such as slight abdominal discomfort or headaches, and may occur in rare cases. Report more serious side effects to your physician and take Viagra Professional only as prescribed by a medical professional.
