In a double blind placebo controlled clinical evaluation of maintenance therapy in chronic schizophrenic female outpatients, thiordazine in single daily doses not exceeding 375 mg./day for 6 months was shown to be effective maintenance treatment compared with PL, thereby establishing the sensitivity of the experiment. Pimozide was also shown to be effective in a single oral dose not exceeding 16 mg./day and comparable overall to the standard drug. The experimental design was based on the anticipated retrogression of PL treated subjects during the 6-month study period, which was reflected in 5 of 9 (56%) "treatment failures" in the PL group compared to 2 of 14 (14%) and 2 of 12 (17%) in the THI and PIM groups, respectively. In addition, in some instances improvement over baseline evaluations was noted in both drug groups, particularly on global impression. Though some items of the BPRS exhibited Drug: PL differences, the scale in general was felt to be rather insensitive for this kind of study. Social adjustment ratings on a special scale completed by the patients and families alike, were also found to be insensitive to treatment differences. Side effects most often seen with THI were sedation, EKG and liver function abnormalities. Headache and restlessness occurred most often with PIM. Extrapyramidal symptoms and insomnia were seen most often with PIM and PL equally.

This research compared the long-term efficacy and safety of iloperidone with those of haloperidol in individuals with schizophrenia. Data were pooled from 3 prospective multicenter studies, each with 6-week stabilization followed by 46-week double-blind maintenance phases. Patients were randomized to iloperidone 4 to 16 mg/d or haloperidol 5 to 20 mg/d. Patients included in this analysis completed the initial 6-week phase with at least 20% reduction in Positive and Negative Syndrome Scale (PANSS) total score at weeks 4 and 6, had 7-item Clinical Global Impressions of Change (CGI-C) scores less than 4, received 1 or more doses of long-term phase medication, and had 1 or more efficacy/safety assessments during the long-term phase. The primary efficacy variable was time to relapse, defined as a 25% or more increase in PANSS total score, including at least a 10-point change; discontinuation because of lack of efficacy; aggravated psychosis with hospitalization; or 2-point increase in the 7-item CGI-C after week 6. Of 1644 patients randomized and 1326 completing the 6-week phase, 473 (iloperidone, n = 359; haloperidol, n = 114) were included in the long-term efficacy analysis, and 489 (iloperidone, n = 371; haloperidol, n = 118) in the safety analysis. Iloperidone was equivalent to haloperidol in time to relapse. The most common adverse events were insomnia (18.1%), anxiety (10.8%), and schizophrenia aggravated (8.9%) with iloperidone, and insomnia (16.9%), akathisia (14.4%), tremor (12.7%), and muscle rigidity (12.7%) with haloperidol. The Extrapyramidal Symptoms Rating Scale scores improved with iloperidone and worsened with haloperidol. Metabolic changes were minimal for both groups. Mean changes in Fridericia's QT interval correction were 10.3 msec (iloperidone) and 9.4 msec (haloperidol) at end point. Iloperidone demonstrated long-term efficacy equivalent to haloperidol and a favorable long-term safety profile, potentially making this agent a suitable option as maintenance therapy for schizophrenia.

Objectives. The aim of this non-randomized, single-arm, multi-center, 9-month extension study was to evaluate the maintained efficacy and tolerability of long-acting risperidone injection when we switched to it from previous oral antipsychotics in symptomatically stable patients with schizophrenia or other psychotic disorders. Methods. A total of 98 patients who had completed a previous 12-week acute phase study were included. Efficacy and tolerability were assessed with the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression (CGI), Global Assessment of Functioning (GAF), and Extrapyramidal Symptom Rating Scale (ESRS). Results. The remission rate of 77.6% (76/98) at baseline and 57.1% (56/98) at the end of the study. Of patients who were in remission at baseline, 65.8% (50/76) maintained their remission state until the end. The symptom worsening rate was relatively low (11.1%), and there was no aggravation in mean PANSS total and subscale scores. Spontaneous treatment-emergent adverse events (TEAE) were reported by 21 (21.4%) patients, and most commonly reported adverse events were extrapyramidal symptoms (N=6, 6.1%) and insomnia (N=4, 4.1%). Extrapyramidal symptoms were significantly improved. Conclusions. Switching to long-acting risperidone injection from oral antipsychotics was a safe and well-tolerated strategy for maintaining clinical stability in symptomatically stable patients with schizophrenia.
