It is well-known that antiepileptics influence drug-metabolizing enzymes . It has also been demonstrated in vitro that antiepileptics influence the metabolism of anesthetics. Particularly, carbamazepine has been reported to promote benzodiazepine metabolism by activating cytochrome P-450 (CYP). Valproate has been demonstrated to influence glucuronic acid conjugation and inhibit propofol metabolism, but, to our knowledge, no study has clinically demonstrated its influence. Thus, we hypothesized that oral valproate influences propofol pharmacokinetics and subsequently reduces the propofol dose required during anesthesia. The objective of our study was to investigate the clinical influence of oral valproate on the propofol dose required for sedation during dental treatment in patients with mental retardation. The clinical endpoint was set as the avoidance of complications assumed to be caused by the overdose of an anesthetic, propofol, or a delay in the recovery from anesthesia.
