Switch medication from Olanzapine to Partial antagonist.[4] [5]
Partial antagonist is a collection of antipsychotic drugs having similar properties with respect to switching. A switch to member of the 'partial antagonist' group from anotherdrug should be read as partial antagonist-anotherdrug. Similarly, a switch from a member of the 'partial antagonist' group to anotherdrug should be read as anotherdrug-partial antagonist.
