Feeding and drinking interactions after acute butyrophenone administration
Pharmacology, Biochemistry, and Behavior
|October 1, 1977
Summary
This study investigated how droperidol, haloperidol, and spiroperidol affect feeding and drinking behaviors in rats. These butyrophenones altered food and water intake, particularly in deprived or desalivated conditions, suggesting a role for brain catecholamines.
Area of Science:
- Neuropharmacology
- Behavioral Neuroscience
- Physiology
Background:
- Butyrophenones like droperidol, haloperidol, and spiroperidol are known to influence central nervous system functions.
- Understanding their precise effects on motivated behaviors such as feeding and drinking is crucial for neuropharmacological research.
Purpose of the Study:
- To investigate the dose-dependent effects of droperidol, haloperidol, and spiroperidol on feeding and drinking behaviors in rats.
- To explore the influence of physiological states (food/water deprivation, salivation) and specific feeding stimuli on drug-induced behavioral changes.
Main Methods:
- Administration of various doses of droperidol, haloperidol, and spiroperidol to rats across multiple experimental paradigms.
- Assessment of feeding and drinking responses following food or water deprivation.
- Evaluation of drug effects in desalivated rats and in response to insulin- and 2-deoxyglucose-induced feeding.
Main Results:
- All three butyrophenones exhibited similar effects, generally decreasing drinking at all doses and altering feeding in a dose-dependent manner.
- Feeding and drinking attenuation in desalivated rats was dose-dependent, with normal responses observed when wet mash was provided.
- Haloperidol attenuated, but did not abolish, insulin- and 2-deoxyglucose-induced feeding in sated rats.
Conclusions:
- Butyrophenones significantly impact feeding and drinking behaviors, with effects modulated by physiological state and food/water availability.
- Findings suggest a role for central catecholamines and activation processes in the regulation of feeding and drinking behaviors influenced by these drugs.
