[Psychotropics and weight gain]

Area of Science:

• Pharmacology
• Endocrinology
• Psychiatry

Background:

• Obesity and weight overload are significant global health concerns.
• Weight gain is a frequent and problematic side effect of numerous psychotropic medications.
• Managing psychotropic-induced weight gain is crucial for patient adherence and overall health outcomes.

Purpose of the Study:

• To review and discuss the weight gain potential of various psychotropic drug classes.
• To identify specific medications most associated with significant weight gain.
• To provide a comparative overview of weight gain liability across different psychotropic categories.

Main Methods:

• Literature review of psychotropic medications and their association with weight changes.
• Analysis of clinical data and studies on drug-induced weight gain.
• Categorization of drugs based on their propensity to cause weight gain.

Main Results:

• Atypical antipsychotics, particularly clozapine and olanzapine, exhibit the highest likelihood of inducing weight gain.
• Tricyclic antidepressants, mirtazapine, and most mood stabilizers are also associated with notable weight gain.
• Older antipsychotics appear to cause less weight gain compared to newer agents.
• Selective serotonin reuptake inhibitors (SSRIs) may cause initial weight loss, followed by moderate long-term weight gain.

Conclusions:

• The choice of psychotropic medication should consider its potential for weight gain.
• Atypical antipsychotics require careful monitoring for weight-related side effects.
• Further research into mechanisms and management strategies for psychotropic-induced weight gain is warranted.
