Which combination of antipsychotics has the highest overall liability for metabolic abnormalities?

• A. Clozapine and Olanzapine
• B. Quetiapine and Risperidone
• C. Ziprasidone and Aripiprazole
• D. Haloperidol and Lurasidone

Answer: (A)

Metabolic side effects from antipsychotics vary by drug, with some causing more weight gain, insulin resistance, and lipid abnormalities than others. Clozapine and olanzapine have the strongest association with these metabolic issues, largely because their receptor effects promote increased appetite and changes in glucose and lipid metabolism. When both agents with the highest metabolic risk are used together, their effects tend to add up, producing the greatest overall liability for metabolic problems. In contrast, agents like ziprasidone and aripiprazole are known for a comparatively lower metabolic risk, and haloperidol has minimal metabolic impact among typical antipsychotics. Lurasidone has a relatively favorable metabolic profile as well, though no antipsychotic is completely risk-free. So, pairing two drugs with the strongest metabolic risk results in the highest likelihood of metabolic abnormalities. Monitoring of weight, glucose, and lipids is essential when using these medications.
