Switch medication from Aripiprazole LA to Partial agonist.[1]
[2]
Partial agonist is a collection of antipsychotic drugs having similar properties with respect to switching. A switch to member of the 'partial agonist' group from anotherdrug should be read as partial agonist-anotherdrug. Similarly, a switch from a member of the 'partial agonist' group to anotherdrug should be read as anotherdrug-partial agonist.
