Novel symmetrical secondary phosphoric acid esters having the general formula ##SPC1## Wherein the substituent R is positioned in meta or para position relative to the phosphoric acid ester group; processes for the preparation of said esters; and compositions containing said esters. The esters are i.a. useful as selective inhibitors of prostaglandins and compounds with prostaglandin activities. They also selectively antagonize the slow reacting substance (SRS).
