 A long-acting antipsychotic(LAI) is effective in treating schizophrenic patients by stabilizing the blood level. The single LAI dose may be insufficient and may be combined with oral medication, but there is also a risk of recurrence due to low adherence. At our hospital, combination therapy of two types of sustained-release injections were given to 8 patients. The CP conversion value of the oral drug was reduced from an average of 1100.9 to 543.8 by the combined use of LAI, and 4 patients did not take the oral antipsychotic drug. Of the 8 cases, 7 were discharged and 6 were living in the community without being readmitted.

 The problem of side effects is large, and the target is already high-dose multidrug therapy, and ECT and clozapine cannot be selected. It was suggested that the combination therapy may be effective in supporting discharge and maintaining community life.
