Objective: In 2001, the Korean College of Neuropsychopharmacology and the Korean Society for Schizophrenia Research developed the Korean Medication Algorithm Project for Schizophrenia (KMAP-SPR) through an expert consensus of opinion, and updated in 2006. This study constitutes the third revision of the KMAP-SPR.
Methods: A 30-item questionnaire was used to obtain the consensus of experts regarding pharmacological treatment strategies for schizophrenia. The review committee included 69 Korean psychiatrists.
Results: The current schizophrenia algorithm consists of 5 stages. Atypical antipsychotics monotherapy was recommended at Stage 1. Stage 2 is the use of typical or atypical antipsychotic drugs which were not used at Stage 1. Clozapine is the Stage 3 treatment for schizophrenia. Stage 4 consists of the combination of clozapine and other drugs such as antipsychotics, mood stabilizer and antidepressant. Stage5 is the combined treatment of the antipsychotics other than clozapine, mood stabilizer, antidepressant and electroconvulsive therapy. According to clinician’s decision, long-acting injectable antipsychotics can be prescribed at any stage.
Conclusion: Compared to previous versions, it is recommended to use clozapine earlier in treatment-refractory schizophrenia in the KMAP-SPR 2019. Also, the use of long-acting injectable antipsychotics were available at any stage.
