ABSTRACT
OBJECTIVE:To compare Paliperidone sustained-release tablet and Paliperidone palmitate injection in the treatment of schizophrenia in respects of medium-term and long-term efficacy,safety,insight,medication compliance and social function of patients,so ad to provide reference for drug selection in the clinic.METHODS:Eighty-four schizophrenia patients selected from our center during Mar.2015-Jun.2016 were divided into Paliperidone sustained-release tablet group (group H,44 cases) and Paliperidone palmitate injection group (group Z,40 cases).Group H was given Paliperidone sustained-release tablet orally with initial dose of 3 mg/d,gradually increasing to 9 mg/d 2 weeks later according to disease condition;the drug dose was adjusted and ranged 3-12 mg/d according to disease condition.Group Z was given Paliperidone palmitate injection intramuscularly,150 mg on 1st day,100 mg on 8th day,and then given injection once a month,drug dose was adjusted according to disease condition (75,100,150 mg).Treatment course of 2 groups lasted for 12 months.Before treatment,1,2,3,6,9,12 months after treatment,Positive and Negative Syndrome Scale (PANSS) was used to evaluate therapeutic efficacy;Scale to Assess Unawareness of Mental Disorder (SAUMD) was used to evaluate the cognition of patients to disease;Medication Adherence Rating Scale (MARS) was used to evaluate medication compliance;Personal and Social Performance Scale (PSP) was used to evaluate patient's social function.The occurrence of ADR was observed during treatment.RESULTS:3,2 patients withdrew from group H,Z during treatment.Before treatment,there was no statistical significance in PANSS,SAUMD,MARS,PSP scores between 2 groups (P＞0.05).1,2,3,6,9,12 months after treatment,PANSS and SAUMD scores of 2 groups were decreased significantly,while MARS and PSP scores were increased significantly,compared to before treatment,with statistical significance (P＜0.05).9,12 months after treatment,PANSS and SAUMD scores of group Z were decreased significantly,while MARS and PSP scores were increased significantly,compared to group H,with statistical significance (P＜0.05).There was no statistical significance in the occurrence of ADR between 2 groups (P＞0.05).CONCLUSIONS:For schizophrenia,Paliperidone palmitate injection is better than Paliperi done sustained-release tablet in respects of medium-term and long-term efficacy,patient's insight,medication compliance,social function recovery;the longer the time,the more prominent the superiority.There is no significant difference in safety between them.
