Pharmacokinetics and pharmacodynamics of famotidine in patients with reflux oesophagitis

Summary The pharmacokinetics, pharmacodynamic effect and clinical efficacy of famotidine were studied in 10 patients with reflux oesophagitis Grades I and II. For the pharmacokinetic studies the patients received 20 mg famotidine i. v.The half-life of famotidine was 3.8 h, the total plasma clearance was 297 ml·min^–1, and a steady state volume of distribution of 1.21·kg^–1 was found. For pharmacodynamic assessment, intraoesophageal pH-metry was performed without and after acute treatment with famotidine 20 mg i. v. and following 3 weeks of oral famotidine 80 mg b. d. The resultant percentage total acid exposure time (pH<4 within 24 h) were 23.9%, 19.0% and 19.2% (median), respectively (NS). At the end of 6 weeks of oral therapy, symptomatic and endoscopic improvement had occurred in 9 and 5 patients, respectively.Our study shows that the pharmacokinetics of famotidine in patients with reflux oesophagitis is comparable to that in healthy volunteers and peptic ulcer patients. The clinical response to the treatment appeared comparable to that found after other H₂-receptor antagonists.

目的：评价法莫替丁（高舒达）、羟氨苄青霉素、替硝唑三联疗法对幽门螺杆菌（Ｈｐ）相关性消化性溃疡的疗效。方法：将８５例Ｈｐ阳性的十二指肠和／或胃溃疡患者随机分为２组：①法莫替丁组，４２例，每次口服法莫替丁２０ｍｇ、羟氨苄青霉素１０００ｍｇ、替硝唑５００ｍｇ，均每日２次，；②兰索拉唑（达克普隆）组４３例，每次口服兰索拉唑３０ｍｇ、羟氨苄青霉素１０００ｍｇ、替硝唑５００ｍｇ，也均为每日２次，进行对照观察。均２周为１疗程，疗程结束达４周时复查Ｈｐ。结果：兰索拉唑组有３例因过敏性皮疹终止治疗，余下４０例用于统计学分析。法莫替丁组和兰索拉唑组Ｈｐ根除率分别为８８．１％和９０．０％；十二指肠溃疡和／或胃溃疡的愈合率分别为９０．５％和９２．５％。结论：法莫替丁组的Ｈｐ根除率和溃疡愈合率与兰索拉唑组相比较，两组间的差异无显著性（Ｐ＞０．０５）。表明两种三联疗法对根除Ｈｐ和治疗消化性溃疡均有良好效果，均是可供选择的治疗方案。但前者有副作用较少，价格较低廉的优点     

Effect of exogenous administration of transforming growth factor-beta and famotidine on the healing of duodenal ulcer under the impact of indomethacin

BACKGROUND: Non-steroidal anti-inflammatory drugs delay ulcer healing and cause refractory peptic ulcers in humans. OBJECTIVE: To study the effects of growth factors on experimental duodenal ulcer healing in indomethacin-treated rats. METHODS: Duodenal ulcers were induced in male Wistar rats by the serosal application of 75% acetic acid for 10 s. Rats were then treated with indomethacin (2 mg/kg/day; s.c.), transforming growth factor beta (15 ng locally injected subserosally at the ulcer site) or famotidine (5 mg/kg/day; p.o.), vehicle or combinations of treatments. On day 5, 8 or 12, rats were sacrificed and the ulcer area planimetrically measured under a dissecting microscope. Macroscopic area, microscopic diameter, collagen content and mucosal regeneration were assessed in histological preparations. Gastric secretion was assessed also in the pylorus-ligated rat-model. Data expressed as median and ranges were analyzed by non-parametric test. RESULTS: Indomethacin delayed ulcer healing but transforming growth factor-beta and famotidine improved ulcer healing and reversed the effects of indomethacin. Maximal differences were observed on day 8. Transforming growth factor-beta was associated with an increase in epithelial and granulation tissue cell proliferation. Famotidine induced a profound inhibition of gastric secretion and increased collagen secretion but it did not affect cell proliferation. CONCLUSIONS: Transforming growth factor-beta and famotidine accelerate ulcer healing delayed by indomethacin.
