Sildenafil is an oral medication called a phosphodiesterase-5 PDE5 inhibitor approved for the treatment of pulmonary arterial hypertension. Sildenafil (Revatio) was approved in 2005 based on a 12-week study that showed improvements in six minute walk distance. 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.

As you would expect, the higher dose has more side effects. In my practice, when I start sildenafil I do so at the 20mg three times daily dose.

That warning came from late-breaking results of the SIOVAC trial that were presented at the European Society of Cardiology meeting in Barcelona, Spain.
