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.
我们已获得双氯芬酸3的新糖基衍生物，并研究了其在胃肠道系统中的致溃疡作用。将游离酸形式的双氯芬酸1及其衍生物3以20mg/kg的单剂量和5mg/kg的5个剂量经口给予大鼠。衍生物3的单剂量引起的刺激比1小；多次给药后未观察到衍生物3的刺激作用。
