The gastric antisecretory effects of clofibrate in the rat.

The object of this study was to explore the effect of clofibrate on gastric secretion. The volume and the total acid output of Shay-treated rats (pyloric ligation) was studied after intragastric, intraduodenal, intramuscular and intraperitoneal administration of clofibrate. The experimental model was a factorial (3 X 4) random block design. The treatment factor had 3 levels: water, oil and clofibrate. The route of administration factor had 4 levels: intragastric, intraduodenal, intraperitoneal and intramuscular. The data were analyzed by analysis of variance. Compared to the control group (water and oil) the intraduodenally and intraperitoneally administered clofibrate produced a statistically significant (p less than 0.001) reduction in the volume and total acid output. The intragastric and intramuscular groups did not show a statistically significant reduction on the gastric secretion. It is concluded that clofibrate acts systemically rather than locally to reduce gastric secretion.
