RESUMEN
Quetiapine is an atypical antipsychotic that is frequently used to manage delirium in geriatric patients. Acute pancreatitis associated with quetiapine has rarely been reported. A 70-year-old male presented with severe abdominal pain a few hours after taking a dose of quetiapine prescribed for delirium. Despite the lack of risk factors of pancreatitis in his medical history, the patient had a slight increase of serum lipase and amylase levels. His general condition improved on discontinuation of quetiapine. A month later, quetiapine was readministered for the recurrence of delirium. Subsequently, the patient developed the same symptom with a significant increase in serum pancreatic enzyme levels, confirming that quetiapine induced the pancreatitis. We reported the first case of quetiapine-induced pancreatitis in Korea, together with a review of the literature.
