Sildenafil Produces Significant Haemodynamic Response in Patients With Pulmonary Arterial Hypertension Treated With Bosentan: Presented at ESC
A single oral dose of sildenafil has beneficial haemodynamic effects when added to bosentan in patients with PAH pulmonary arterial hypertension (PAH), according to study results presented here at the European Society of Cardiology (ESC) Congress.
Use of the phosphodiesterase type 5 inhibitor sildenafil raised no clinically relevant safety concerns and resulted in significant reductions in pulmonary vascular resistance (PVR) and total pulmonary resistance (TPR) in the international, multicentre, open-label, non-comparative, prospective Combination Bosentan and Sildenafil in PAH (COMPASS-1) study
"Within the last 10 years, there has been a remarkable improvement in the treatment of pulmonary arterial hypertension, and there have been many different medical treatments developed," said the study's principal investigator for Germany, Ekkehard Gruenig, MD, Associate Professor and Head, Pulmonary Hypertension Unit, Thorax Clinic, University of Heidelberg, Heidelberg, Germany
