Controlled trial of cimetidine in upper gastrointestinal haemorrhage
Insights
Oral cimetidine did not significantly prevent acute upper gastrointestinal bleeding recurrence in a double-blind trial. This study assessed cimetidine
Area of Science:
- Gastroenterology
- Clinical Pharmacology
Background:
- Acute upper gastrointestinal hemorrhage is a significant clinical concern, often stemming from peptic ulcers.
- Effective preventative strategies for bleeding continuation or recurrence are crucial for patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of oral cimetidine in preventing the continuation or recurrence of acute upper gastrointestinal hemorrhage.
- To assess the role of cimetidine in patients with bleeding peptic ulcers and other upper GI sources.
Main Methods:
- A double-blind, placebo-controlled trial involving 101 patients with acute upper gastrointestinal hemorrhage.
- Patients received either oral cimetidine (800 mg loading dose, then 400 mg six-hourly) or a placebo.
- Endoscopic evaluation was used to identify the source of bleeding in 96% of participants.
Main Results:
- Bleeding continued or recurred in 21.5% of patients receiving cimetidine versus 24% receiving placebo.
- Peptic ulcer was the primary source of bleeding, identified in 70% of cases.
- No statistically significant advantage of cimetidine was observed when analyzed by patient age or bleeding severity.
Conclusions:
- Oral cimetidine demonstrated no significant benefit in preventing the continuation or recurrence of acute upper gastrointestinal hemorrhage in this study population.
- Further research may be needed to explore alternative or adjunctive therapies for managing upper GI bleeding.
Abstract:
One hundred and one patients were studied in a double-blind controlled trial to assess the role of oral cimetidine in preventing the continuation or recurrence of acute upper gastrointestinal haemorrhage from various sources, chiefly peptic ulcer. The dose of cimetidine was 800 mg on entering the study followed by 400 mg six hourly. The source of bleeding was identified endoscopically in 96% of patients, peptic ulcer comprising 70%. Bleeding continued or recurred in 11 of 51 (21.5%) of patients on cimetidine and in 12 of 50 (24%) of patients on placebo. Analysis of the effect of cimetidine according to age or severity of bleeding showed no significant advantage for the drug.
