Today we will talk about one of the best friends of the elderly men who still have the fire in their bed, and if we talk about sildenafil citrate, or better known as Viagra, Revatio and others, is a drug used to treat dysfunction erectile and pulmonary arterial hypertension. It was originally developed by British scientists and then marketed by the pharmaceutical company Pfizer. It acts by inhibiting specific phosphodiesterase type 5 cyclic GMP, an enzyme that promotes degradation of cGMP, which regulates the blood flow in the penis. Since its availability in 1998, sildenafil has been the main treatment for erectile dysfunction, its main competitors in the market are vardenafil (Levitra) and tadalafil (Cialis).

It could be said that Sildenafil citrate is a potent vasodilator whose best known use is for the treatment of erectile dysfunction. Its use has been standardized for the treatment of this problem in all areas, including diabetes. For most men, the recommended dose is 50 mg. Based on effectiveness and tolerance, the dose may be increased to a recommended maximum of 100 mg or decreased to 25 mg. The frequency of the maximum recommended dose is once daily. Be sure to tell your doctor about all the medicines you take and any other medical conditions you may have, as the dose may need to be adjusted. The most common is the consumption of 50-100 mg 30 minutes before intercourse. The dose for the treatment of pulmonary arterial hypertension is 20 mg three times a day.
