title: FCE 20700, a cytoprotective PGE2 derivative, does not interfere with the antiinflammatory activity of indomethacin.
abstract: A study was made of the interaction between FCE 20700 (11-deoxy-13,14-didehydro-16(S)-methyl-PGE2 methylester) at a fixed dose of 250 mcg/kg and the ulcerogenic and antiinflammatory effect of indomethacin (I) on rat carrageenin paw edema. The combination tested showed the same antiinflammatory effect as I alone: potency ratio FCE 20700 + I/I was 1.03, demonstrating the lack of interaction between the two compounds. Moreover the gastric lesions in FCE 20700 + I treated rats were markedly reduced, allowing the dosage of I to be increased by about three times without increasing its ulcerogenic effect.
