title: Severe amlodipine intoxication treated by hyperinsulinemia euglycemia therapy.
abstract: The objective of this study was to report a use of hyperinsulinemia euglycemia therapy in severe amlodipine intoxication. Intoxication with 420 mg of amlodipine caused severe hypotension in a 20-year-old female patient. The patient was initially treated with fluids, calcium gluconate, and epinephrine without effect. She was then given hyperinsulinemia euglycemia therapy. We observed a rise in blood pressure (BP) approximately 30 min after insulin was given and the BP was subsequently responsive to epinephrine. The patient was weaned from pressors 5 h after insulin therapy. The trachea was extubated 24 h after ingesting amlodipine, and the patient was transferred for psychiatric treatment 3 days later. This possible positive inotropic effect of insulin therapy in patients with calcium channel blocker intoxication supports previous findings. It is suggested that hyperinsulinemia euglycemia therapy may be considered as a first-line therapy in amlodipine intoxication.
