Cumulative dose-effect curves in a conflict test with incremental shock
Psychopharmacology
|January 1, 1982
Summary
This study evaluated drug effects in a conflict test. Anxiolytics like chlordiazepoxide increased conflict responses, while non-anxiolytics such as morphine decreased them, confirming prior findings.
Area of Science:
- Pharmacology
- Behavioral Neuroscience
- Drug Action
Background:
- The Geller-Seifter conflict test is a standard model for assessing anxiolytic and anxiogenic drug effects.
- Previous studies utilized a one-dose-per-session design to evaluate drug efficacy.
Purpose of the Study:
- To generate cumulative dose-effect curves for several psychoactive drugs in a conflict test.
- To compare the effects of anxiolytics and non-anxiolytics using a cumulative dosing paradigm.
Main Methods:
- Utilized a Geller-Seifter conflict test with incremental shock.
- Administered cumulative doses of chlordiazepoxide, diazepam, meprobamate, pentobarbital, morphine, and d-amphetamine.
Main Results:
- Anxiolytic drugs (chlordiazepoxide, diazepam, meprobamate, pentobarbital) significantly increased responses under conflict conditions at certain doses.
- Non-anxiolytic drugs (d-amphetamine, morphine) demonstrated dose-related decreases in conflict responses.
- The findings aligned with results from traditional one-dose-per-session experimental designs.
Conclusions:
- Cumulative dosing in the Geller-Seifter conflict test effectively differentiates anxiolytic from non-anxiolytic drug profiles.
- This method provides consistent results with established experimental paradigms for drug evaluation.
