    Notes: The ability of ranitidine to protect the human gastric mucosa against aspirin-induced damage was investigated by timed measurements of blood loss collected by gastric washing. Ranitidine (150 mg) 1 h or 5 h before 900 mg aspirin (5 doses of each) over 48 h reduced subsequent mean bleeding from 7.7 μi/10 min to 2.6 μl/10 min or 3.4 μl/10 min, respectively. Both regimens were antisecretory at the time of aspirin administration, as judged by a rise in the pH of the aspirated washings. The prolonged protection against aspirin-induced bleeding achieved with twice daily dosing with ranitidine has dinical potential in the management of patients taking anti-inflammatory drugs.

    Notes: The effects of bedtime 70 μg and twice daily 35 μg doses of enprostil on 24-hour intragastric acidity were investigated in nine duodenal ulcer patients in remission. Median nocturnal acidity decreased significantly by 30% with 35 μg twice daily, and by 48% with 70 μg at bedtime. In a clinical trial using bedtime dosing, 102 duodenal ulcer patients randomly received either ranitidine 300 mg or enprostil 70 μg. More ulcers healed after 4 and 8 weeks treatment with ranitidine than with enprostil (76% ranitidine vs 52% enprostil, at 4 weeks p= 0.0065 and 94%vs 68%, respectively at 8 weeks, P= 0.0007). However, 6 months after cessation of treatment there was no material difference in overall outcome. Despite combining mucosal protection with acid inhibition enprostil treatment conferred no advantage over simple acid inhibition.

    Notes: Summary Famotidine, a new H2-receptor antagonist was tested for drug interactions using 14C-aminopyrine and antipyrine. Elimination of these model drugs was studied before and during 8 days of famotidine dosing in 8 healthy volunteers. Famotidine 40 mg b.d. did not inhibit aminopyrine 14CO2 half-life or antipyrine clearance although an unexpected mild enzyme inducing effect could not be excluded. It is unlikely that famotidine will inhibit hepatic drug metabolism during routine clinical use as the daily dose is expected to be 40 mg/day but interactions should be looked for if more prolonged or larger doses are used.
