Irritation of gastrointestinal mucosa by new glycosyl derivative of diclofenac in comparison with diclofenac in rats.
We have obtained new glycosyl derivative of diclofenac 3 and studied its ulcerogenic effect in the gastrointestinal system. Diclofenac as free acid 1 and its derivative 3 were administered to rats per os in a single dose 20 mg/kg and in 5 doses of 5 mg/kg. Single dose of derivative 3 caused less irritation than 1; after multiple administration no irritating effect of derivative 3 was seen.
