Abstract. Aim The treatment of patients with pulmonary arterial hypertension remains a challenge. We set out to investigate the use of sildenafil, a selective. 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. 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. 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. Madrid, Spain—The prescribing of sildenafil to treat residual hypertension in patients with valvular heart disease should raise a red flag for pharmacists. That warning came from late-breaking results of the SIOVAC trial that were presented at the European Society of Cardiology meeting in Barcelona, Spain. At a Hot Line LBCT Session at the ESC Congress, Hospital General Universitario Gregorio Marañon–led researchers reported that off-label use of the drug led to worse clinical outcomes, including twice the risk of hospitalization, compared with placebo.“Valvular disease is considered the next cardiac epidemic because of its strong association with age and the rapid aging of the population worldwide,” said principal investigator Javier Bermejo, MD, Ph D. “The only established treatment is repair or replacement of the valve surgically or percutaneously. But symptoms often remain or reappear in the long-term. Residual pulmonary hypertension is the most important risk factor for death and disability after successful correction of the valvular lesion.”Increased blood pressure in the pulmonary artery might persist after valve treatment, according to the study, which points out that sildenafil—which usually is used to treat erectile dysfunction—is frequently prescribed off-label in patients with retrograde pulmonary hypertension. Conducted in 17 public hospitals and coordinated by the Spanish Network Centre for Cardiovascular Research (CIBERCV), the SIOVAC trial looked at whether sildenafil can improve long-term outcomes in patients with residual pulmonary hypertension after correction of a valvular lesion.
