Pharmacokinetic Interactions between Valproic Acid and Lorazepam (PIVOtAL Study): A Review of Site-Specific PracticesKeywords: valproic acid, lorazepam, pharmacokinetics, drug-drug interaction, uridine 5′-diphosphate-glucuronosyltransferases acide valpro？que, lorazépam, pharmacocinétique, interaction médicament-médicament, uridine 5′-diphosphate glucuronosyltransférases Abstract: Coadministration of lorazepam and valproic acid is identified by tertiary references as causing a major drug interaction that requires therapy modification and dosage adjustments. The proposed mechanism involves inhibition of lorazepam glucuronidation via direct inhibition of uridine 5′-diphosphate-glucuronosyltransferase enzymes by valproic acid. However, the clinical significance of this interaction is unclear
