Adding olanzapine to risperidone.
General information- Risperidone is principally metabolized by CYP2D6 to an active metabolite 9-OH-risperidone (paliperidone).
- Olanzapine is principally metabolized by CYP1A2 and CYP2D6.
Start olanzapine- The combination of these 2 antipsychotics seems to be irrational from a pharmacotherapeutical point of view.
Cave- Agents with anticholinergic properties may have additive (side)effects when used in combination. [6]
