[Antihistaminergic antipsychotics cause weight gain]
1Klinik für Psychiatrie und Psychotherapie, Universitätsklinikum der RWTH Aachen, Aachen.
Antipsychotic medications can cause significant weight gain, impacting patient health and treatment adherence. This weight gain is linked to specific receptor interactions, particularly with histamine H1 receptors, influencing appetite signals in the brain.
Area of Science:
- Pharmacology
- Neuroscience
- Endocrinology
Context:
- Weight gain is a significant side effect of antipsychotic medications.
- This adverse effect poses risks for metabolic and cardiovascular health.
- It negatively impacts patient adherence to antipsychotic therapy.
Purpose:
- To explore the mechanisms behind weight gain induced by antipsychotics.
- To investigate the role of histamine H1 and serotonin receptors.
- To understand the hypothalamic adenosine monophosphate-activated protein kinase (AMPK) pathway in antipsychotic-associated weight gain.
Summary:
- Different antipsychotics exhibit varying effects on body weight.
- These differences are primarily attributed to their affinity for histaminergic H1 and serotonergic receptors.
- Antipsychotics causing substantial weight gain increase hypothalamic AMPK activity, which integrates appetite signals.
Impact:
- Provides insight into the neurobiological basis of antipsychotic-induced weight gain.
- May inform the development of antipsychotics with a lower risk of weight gain.
- Highlights the importance of monitoring metabolic health in patients on antipsychotic therapy.
