The anti-inflammatory activity and the eicosanoid generation in rat gastric mucosa after a single oral dose of S-(+)-2(4-fluorophenyl)-alpha-methyl-5-benzoxazolacetic acid (flunoxaprofen, 10 mg/kg) or indomethacin (5 mg/kg) were compared. The two compounds, at the dose used, show a similar degree of anti-inflammatory activity (50% inhibition of carrageenan-induced oedema in rat paw). Moreover flunoxaprofen does not modify the formation of 6-keto-PGF1 alpha by rat gastric mucosa in vitro while indomethacin causes 50% inhibition of gastric cyclooxygenase activity. This biochemical change induced by indomethacin is associated with gastric lesions. Chronic treatment of rats with flunoxaprofen (5 or 50 mg/kg p.o. for 15 days) shows an anti-inflammatory activity in the range of 60-70% inhibition in the rat paw oedema test without gastric mucosa damages and prostaglandin synthesis inhibition.

Abstract
The anti-inflammatory activity and the eicosanoid generation in rat gastric mucosa after a single oral dose of S-(+)-2(4-fluorophenyl)-alpha-methyl-5-benzoxazolacetic acid (flunoxaprofen, 10 mg/kg) or indomethacin (5 mg/kg) were compared. The two compounds, at the dose used, show a similar degree of anti-inflammatory activity (50% inhibition of carrageenan-induced oedema in rat paw). Moreover flunoxaprofen does not modify the formation of 6-keto-PGF1 alpha by rat gastric mucosa in vitro while indomethacin causes 50% inhibition of gastric cyclooxygenase activity. This biochemical change induced by indomethacin is associated with gastric lesions. Chronic treatment of rats with flunoxaprofen (5 or 50 mg/kg p.o. for 15 days) shows an anti-inflammatory activity in the range of 60-70% inhibition in the rat paw oedema test without gastric mucosa damages and prostaglandin synthesis inhibition.
