The medicine contains a salt known as sildenafil citrate the names from which the medicine is being sold in the market are Viagra and Revatio and some other brand names are also available in the market but the most known are the Viagra and the revatio. British scientists were the first who researched on the salt got some of the results and then a company known as Pfizer brought this medicine to the market. Viagra is basically medicine which is used for the erectile malfunctioning and pulmonary arterial hypertension.
As well as erectile dysfunction, sildenafil citrate is also effective in the rare disease pulmonary arterial hypertension (PAH). It relaxes the arterial wall, leading to decreased pulmonary arterial resistance and pressure. This, in turn, reduces the workload of the right ventricle of the heart and improves symptoms of right-sided heart failure. Because PDE-5 is primarily distributed within the arterial wall smooth muscle of the lungs and penis, sildenafil acts selectively in both these areas without inducing vasodilation in other areas of the body. Pfizer submitted an additional registration for sildenafil to the FDA, and sildenafil was approved for this indication in June 2005. The preparation is named Revatio, to avoid confusion with Viagra, and the 20-milligram tablets are white and round. Sildenafil joins bosentan and prostacyclin-based therapies for this condition.
Viagra’s primary function was the treatment of erectile malfunctioning and due to excellent results in the field of erectile malfunctioning Viagra is now the basic treatment of erectile malfunctioning in all conditions and for all type of patients except the diabetic patients.
The basic function of Viagra is that it inhibits an enzyme cGMP-specific phosphodiesterase type 5 which regulates the blood flow in the penis. Viagra was available in the market from 1998. Before 1998 the researches were being made by the company Pfizer but it originally came in the market in 1998.
People on antidepressants may feel sexual malfunctioning either due to their illness or due to their treatment a recent research has showed that Viagra will increase the sexual activity in this case. Viagra is available in many qualities and many types due to its adverse use all over the world. Viagra medicine is now a day’s very much famous all around the world due to which many local companies are now producing Viagra tablets.
Due to the restrictions in the sale of Viagra medicine or not to be given to every person there is a lot of trouble for the people but no worries WWW.MAYSIRIS.COM
