Vialis

What is Vialis?
Sildenafil, commonly known by the trade name Viagra is an oral medication used for the treatment of erectile dysfunction (ED). Pfizer commercially released Viagra in 1996 officially making it the first drug ever approved by the FDA for the treatment of ED. Since its inception many other brands of Sildenafil have come to the market place taking the once held monopoly away from Pfizer as well as several other ED medications composed of different drugs, Cialis (Tadalafil) being the most notable and largest competition for Viagra.The function of Viagra is relatively simple – it relaxes the muscle and increases the blood flow to the penis. An erection is nothing more than blood flow to the penis. When blood flow is weak so is the erection. If we increase blood flow we increase the strength of the erection and the ability to maintain it.The specifics of action involve the binding of nitric oxide to the guanylate cyclase receptors, which increases cGMP levels. This produces a smooth muscle relaxation, which in turn opens the pathway for increased blood flow. Viagra belongs to the class of drugs known as cGMP Specific Phosphodiesterase type 5 or PED5.Important note: Viagra as well as other PED5 medications cannot cause or promote an erection without sexual stimulation. They do not have an effect on libido. The subject must be sexually aroused to obtain an erection. In the case of Viagra the problem for the subject is that the desire is there but the erection is not found. Viagra should reverse this issue if blood flow is the cause.
