Hypothermia in an Adolescent Due to Probable Drug-Drug Interaction Involving Clobazam

J Pediatr Pharmacol Ther. 2019 Mar-Apr;24(2):156-159. doi: 10.5863/1551-6776-24.2.156.

Abstract

We report on a 16-year-old female who developed hypothermia as a result of a drug-drug interaction that produced supratherapeutic serum concentrations of clobazam. Although clobazam and its active metabolite (N-desmethylclobazam) are metabolized by cytochrome 2C19 (CYP2C19), literature suggests that clobazam-associated drug interactions involving this isoenzyme are not clinically relevant because of its wide therapeutic index. This report describes clobazam-associated hypothermia due to supratherapeutic serum concentrations of clobazam that resulted from the combination of 2 CYP2C19 inhibitors.

Keywords: CYP2C19; clobazam; drug interaction; hypothermia; omeprazole; oxcarbazepine; pediatric.
