Adding risperidone to valproic acid.

Infobord.png General information
  • Valproic acid is principally metabolized by CYP2C9, CYP2C19, CYP2A6 and UDP-glucuronosyltransferases. Valproic acid is an inhibitor of the enzymes CYP2C9, epoxide-hydroxylase and UDP-glucuronosyltransferases.
  • Risperidone is principally metabolized by CYP2D6 to an active metabolite 9-OH-risperidone (paliperidone).
  • Risperidone is principally metabolized by CYP2D6 to an active metabolite.

  • Coadministration with risperidone may alter the serum concentrations of valproic acid, although data are conflicting.
  • Start according to the general dosing advice. Monitoring of the pharmacologic response and serum valproate levels is recommended.[6]
Letopbord.png Cave
  • Dose-related generalised oedema is reported. [7]
  • Antipsychotics lower the seizure threshold and may antagonise the anticonvulsant effect of valproate. [8]
