Chlordiazepoxide and stress tolerance in rats
Pharmacology, Biochemistry, and Behavior
|March 1, 1987
Summary
Chlordiazepoxide reduced stress ulcers in rats initially. However, stopping the drug during chronic stress led to stomach erosions, indicating withdrawal effects contrary to stress adaptation.
Area of Science:
- Pharmacology
- Neuroscience
- Gastroenterology
Background:
- Chronic stress is a known risk factor for developing gastric ulcers.
- Pharmacological interventions are often explored to mitigate stress-induced pathologies.
- Understanding drug withdrawal effects in the context of chronic stress is crucial.
Purpose of the Study:
- To investigate the effect of chlordiazepoxide on acute stress-induced gastric ulcers in rats.
- To examine the impact of chlordiazepoxide withdrawal during chronic stress exposure on gastric pathology.
- To explore the interplay between stress adaptation and drug withdrawal.
Main Methods:
- Rats were subjected to restraint stress to induce gastric ulcers.
- Chlordiazepoxide or vehicle was administered intraperitoneally.
- Drug administration was varied during acute and repeated stress sessions.
- Gastric pathology was assessed to quantify ulcer severity and erosions.
Main Results:
- Chlordiazepoxide administration attenuated acute restraint stress-induced gastric ulcers.
- Withholding chlordiazepoxide during repeated restraint sessions resulted in significant stomach erosions.
- Vehicle-treated control rats exhibited adaptation to chronic stress, showing reduced gastric pathology.
Conclusions:
- Chlordiazepoxide exhibits protective effects against acute stress ulcers.
- Abrupt cessation of chlordiazepoxide during chronic stress can precipitate gastric pathology, suggesting withdrawal-induced erosions.
- These findings highlight the importance of considering drug withdrawal in the context of stress adaptation and management.
