PGD3 is produced by the metabolism of EPA via the COX pathway.1 It is equipotent to PGD2 in decreasing systemic blood pressure in rats and in decreasing intraocular pressure in rabbits.2,3,4 However, it is 3-5 times more potent than PGD2 in the inhibition of ADP-induced human platelet aggregation.2
