INTRODUCTION: Pulmonary arterial hypertension (PAH) is characterized by an increase in pulmonary vascular resistance, which can lead to right heart failure and death. Endothelin-1 binding ETA and ETB receptors seem to play a critical role in the pathogenesis and progression of the disease, and oral endothelin receptor antagonists (ERAs) have been shown to be an effective treatment. Bosentan and ETA-selective ambrisentan are the ERAs currently available for PAH treatment.
AREAS COVERED: On the basis of the analysis of the literature, this paper addresses the efficacy and safety of ambrisentan in the treatment for PAH.
EXPERT OPINION: Ambrisentan has shown an efficacy comparable with other ERAs. Compared with bosentan, ambrisentan seems to have a better safety profile with regards to hepatic safety and drug-drug interactions. On the other hand, ambrisentan shows a higher rate of other adverse events, such as nasal congestion and peripheral edema. Ambrisentan is a viable option for PAH treatment. However, there is still a need for more robust data about long-term mortality, treatment in non-PAH pulmonary hypertension (PH) (such as PH due to left heart disease and PH due to chronic hypoxic lung diseases) and combination therapy.
