The invention relates to the use of derivatives of E-type prostaglandins as EP2 agonists, in general, and, in particular as ocular hypotensives. The PGE derivatives used in accordance with the invention are represented by the following formula I:
wherein the hatched segment represents an &agr; bonds, the solid triangle represents a &bgr; bond, the wavy segments represent &agr; or &bgr; bond, dashed lines represent a double bond or a single bond, X is selected from the group consisting of hydrogen and halogen radicals, R3 is heteroaryl or a substituted heteroaryl radical, R1 and R2 are independently selected from the group consisting of hydrogen or a lower alkyl radical having up to six carbon atoms, or a lower acyl radical having up to six carbon atoms, R is selected from the group consisting of CO2R4, CONR42, CH2OR4, CONR4SO2R4, P(O)(OR4) and
wherein R4 is selected from the group consisting of H, phenyl and lower alkyl having from one to six carbon atoms and n is 0 or an integer of from 1 to 4.
