非甾体抗炎药的胃肠道损伤__培训课件.pptVIP

Conclusions: This study provides both biochemical and direct evidence of macroscopic injury to the small intestine in 68%–75% of volunteers resulting from 2 weeks’ ingestion of slow-release diclofenac ARAMIS —关节炎、风湿病及衰老医学信息系统。 3项随机试验的安全性综合分析结果表明西乐葆的上消化道耐受性明显优于双氯芬酸。 2项OA患者试验的综合结果表明，西乐葆治疗第6周的上消化道症状累积性证据（如腹痛、恶心和消化不良）较双氯芬酸少37%（ P=0.002 ）。西乐葆的上消化道症状累积性证据与安慰剂无显著区别。RA患者的分析报告结果也相似：RA患者服用西乐葆的总体上消化道耐受性明显优于双氯芬酸（ P=0.013 ）。 Reference: 1.

CELEBREX was associated with a 7-fold decrease in the percentage of patients with endoscopic upper GI ulcers compared with ibuprofen (2.6% vs 17.9%, respectively; P=.056). The difference in incidences of erosions was similar. Naproxen resulted in a significantly increased incidence of ulcers compared with placebo (25% vs 2.5%; P.01). T
