Viagra Professional is a more powerful formula of the popular erectile dysfunction drug Viagra, which contains a high-potency concentration of Sildenafil. The drug is recommended mainly for erectile dysfunction (ED), which consists in difficulties with supporting an erection as part of sexual intercourse. However, Sildenafil is once in a while used off label as treatment for conditions, such as pulmonary hypertension or a diminished sexual libido in women. All these treatment modalities involving Sildenafil are based on its ability to induce a considerable dilation of blood vessels, which is the main beneficial property of the drug. Viagra Professional shares similar chemicals properties with other drugs that compose the phosphodiesterase inhibitor class or PDE5 inhibitors, such as Cialis or Vardenafil. Although these ED remedies work through a similar mechanism, Viagra is considered the most notorious representative of PDE5 inhibitors.
How does Viagra Professional help male ED sufferers?
Before the discovery of Viagra, which marked the start of a new era in erectile dysfunction treatment, ED was mostly treated through psychotherapy and herbal remedies. Although these may be effective to some degree in restoring the confidence of a man in his sexual abilities, these treatment methods are far less effective than ED medication. Viagra Professional (Sildenafil) is a high-potency drug that inhibits the PDE5 enzyme in the penis veins. Sexual arousal caused by visual stimuli is transmitted from the brain through the nerves to the veins of the penis. These veins are modified in chamber-like structures that can hold impressive amounts of blood, which is the way an erection is accomplished. After the nerves release nitric oxide (NO), the cells in the blood vessels start to synthesize and release cyclic GMP, which induces a prolonged dilation of blood vessels located in the cavernous bodies. The veins dilate, and thus more blood is allowed to enter the penis, which is the mechanism of an erectile response. However, the PDE5 enzyme is there to destroy the cyclic GMP and finish its influence on the blood vessels, which may disrupt an erection in some susceptible men.
Possible side effects
Viagra Professional through its active ingredient Sildenafil blocks the PDE5 enzyme, and so considerable stimulation through cyclic GMP continues to take place. The erection is sustained by the elevated cyclic GMP levels and the “silenced” PDE5 enzyme in the cavernous bodies. Rarely, one may experience temporary unwanted effects like headaches, nausea or a stuffy nose due to the potent blood vessel dilation properties of Viagra Professional. Talk to your physician and benefit from adequate monitoring during your treatment course with Sildenafil, and also report any undesirable effects that may rarely accompany Sildenafil intake.
