Metabolic syndrome is primarily associated with which class of antipsychotics?

• A. Mood stabilizers
• B. First-Generation Antipsychotics (FGAs)
• C. Antidepressants
• D. Second-Generation Antipsychotics (SGAs)

Answer: (D)

Second-generation antipsychotics carry a higher risk of metabolic syndrome, which includes weight gain, increased waist circumference, dyslipidemia, hypertension, and impaired glucose tolerance. This tendency stems from their pharmacologic profile, especially blockade of histamine H1 and serotonin 5-HT2C receptors, which can boost appetite and alter how the body handles insulin and lipids. Among this class, olanzapine and clozapine are known to have the strongest metabolic effects, while others like risperidone and quetiapine carry moderate risk and aripiprazole, ziprasidone, and lurasidone tend to have lower risk. In contrast, mood stabilizers and antidepressants are not as closely tied to metabolic syndrome as a class, and first-generation antipsychotics, while they can cause weight gain in some cases, are generally less associated with the full metabolic syndrome picture than SGAs. Regular monitoring of weight, waist circumference, glucose, and lipid levels is important when using SGAs.
