Biochem/physiol Actions

Potent, highly selective and orally available agonist for the PGI2 receptor (IP receptor); nonprostanoid IP receptor agonist
Selexipag is a potent, highly selective and orally available nonprostanoid agonist for the PGI2 receptor (IP receptor). Selexipag is readily hydrolyzed to the active metabolite ACT-333679 (MRE-269), which is also a potent and selective agonist at IP receptors. In contrast to the prostacyclin analogs iloprost and beraprost, selexipag and metabolite ACT-333679 does not contract gastric fundus up to mM concentrations.
