Abstract:
Weight gain remains a well recognized yet difficult to treat adverse effect of many anti-psychotic drugs including agents of the first and second generation. The weight gain liabilities of antipsychotic drugs are partly associated with their ability to increase appetite. Most behavioral interventions for weight control remain of limited efficacy, possibly because they do not specifically target the neuroendocrine factors regulating appetite. Identifying new weight management interventions directly acting on the biochemical and neuroendocrine mechanisms of anti-psychotic induced weight gain may help to improve the efficacy of behavioral weight management programs. Such potentially specific strategies include (1) using diets which do not increase appetite despite calorie restriction; (2) countering thirst as an anticholinergic side-effect; (3) discouraging cannabis use and (4) adding metformin to a behavioral intervention. In view of our currently rather limited treatment repertoire it seems timely systematically to explore such novel options.
Insights
Antipsychotic medications often cause weight gain by increasing appetite. New strategies targeting appetite regulation, like specific diets or metformin, may improve weight management for patients on these drugs.
Area of Science:
- Pharmacology
- Neuroendocrinology
- Behavioral Science
Background:
- Weight gain is a common and challenging side effect of first and second-generation antipsychotic medications.
- Antipsychotic-induced weight gain is linked to increased appetite, making behavioral interventions less effective.
- Current weight management options for patients on antipsychotics are limited.
Purpose of the Study:
- To explore novel interventions for managing antipsychotic-induced weight gain.
- To identify strategies that specifically target the neuroendocrine mechanisms regulating appetite.
- To improve the efficacy of behavioral weight management programs in this patient population.
Main Methods:
- Review of potential interventions targeting appetite regulation.
- Consideration of dietary approaches that do not increase appetite.
- Evaluation of strategies to manage anticholinergic side effects like thirst.
- Assessment of the role of discouraging cannabis use.
- Exploration of metformin as an adjunct therapy.
Main Results:
- Novel strategies may enhance weight management efficacy.
- Dietary modifications, managing thirst, and discouraging cannabis use are potential avenues.
- Metformin may be a beneficial addition to behavioral interventions.
Conclusions:
- Systematic exploration of novel weight management options is timely.
- Targeting specific neuroendocrine factors offers a promising approach.
- Improving treatment options for antipsychotic-induced weight gain is crucial for patient care.
