- © 2022 Elsevier LtdPulmonary arterial hypertension (PAH) is a severe clinical condition that significantly affects patients¿ quality of life and survival. Since the emergence of prostanoids 45 years ago, different drugs acting on vasoconstriction/vasodilation mechanisms have been developed for the treatment of PAH. Current evidence shows that better results occur when combined therapy is initiated up-front with periodic and systematized evaluations for escalation and switching. Among these strategies, riociguat has a relevant role, supported by the results of several clinical studies. This document issues recommendations by a panel of experts who analysed and discussed the indications and limitations for riociguat in PAH in different institutions of the Mexican health system.
