Adding aripiprazole to risperidone.
- Risperidone is principally metabolized by CYP2D6 to an active metabolite 9-OH-risperidone (paliperidone).
- Aripiprazole is metabolized by CYP2D6 and CYP3A4 to an active metabolite.
- The combination of these 2 antipsychotics seems to be irrational from a pharmacotherapeutical point of view.
- Agents with anticholinergic properties may have additive effects when used in combination.
