In the initial study, there was not a clear difference between 20mg three times a day and higher doses. In a subsequent study that followed patients for years, the majority of patients increased their dose to 80mg three times daily and had lasting benefit. In 2012, generic Revatio became available as Sildenafil. Most experts that treat PAH believe that over time patients generally do better on the higher dose (80mg) rather than the 20mg dose.

Inhibitors of phosphodiesterase type 5 (PDE5), such as sildenafil, relax blood vessels. These have shown that sildenafil causes a modest reduction in blood pressure, even when taken with other blood pressure-lowering drugs, providing reassurance on safety when taken as a single dose for erectile dysfunction. However, these studies do not offer any insight into the potential of PDE5 inhibition in the long-term treatment of hypertension. We will address this question by investigating the effects of regular administration of sildenafil on blood pressure. It may also be postulated that, because of its mechanism of action, sildenafil will also improve the function of the endothelium, the single layer of cells that lines all blood vessels.

It acts to dilate (widen) the walls of the arteries, increasing blood flow and reducing the strain on the heart. c GMP acts to relax and widen the artery muscles, leading to vasodilation (widening of the arteries) and a reduction in blood pressure. This increases circulation through the lungs, which helps transport oxygen around the body and reduces the burden on the heart. , was a double-blind, placebo-controlled, randomized clinical trial with 278 patients.
