Viagra is not only a drug to treat impotence; this is also effectively used to treat pulmonary arterial hypertension. This was developed and marketed by the pharmaceutical company called Pfizer. The drug Sildenafil Citrate present in Viagra excites the enzymes hosphodiesterase5 in your body. The enzymes in turn relax the blood vessels in penis. When you are slowly sexually excited, blood flows in greater volume through the veins to the corpora cavernosa causing erection. The erection by Viagra is not a forced erection. Without excitation your penis will not erect.
Cialis is another medicine of the same category of Viagra. The recommended dosage is 10 mg and 20 mg. Levitra comes in dosage of 5 mg, 10 mg and 20 mg. among all these medicines Viagra is the most popular and preferred medicine because it has been able to treat millions without any difficulty.
No other medicine has been so much successful like Viagra in treating impotency. PDE-5 is only specific to penis and thus Viagra becomes specific for this enzyme in the penis to cause erection. The side effects which come about due to ingestion of Viagra are due to minimum cross chemical reaction. Sildenafil acts by restraining the cGMP specific phosphodiesterase type 5, which is an important enzyme that regulates the blood flow to penis. It then engrosses in the release of nitric oxide in the corpora cavernosa of the penis. The nitric oxide binds with the receptors of protein guanylate cyclase which results in increased levels of cyclic cGMP. Once this happens there is muscle relaxation and increased blood flow to the area to cause erection.
