PGI₃ is synthesized from EPA by COX and PGI synthase. PGI₃ has a short in vivo half-life and is hydrolyzed to Δ¹⁷-6-keto PGF_1α. The platelet and vascular activity of PGI₃ is equivalent to that of PGI₂.^1,2

Prostaglandin I3 sodium is an inhibitor of platelet aggregation with vasodilatory effects[1].
