ABSTRACT

OBJECTIVE: Refractory schizophrenia (SZ) affects approximately 30% of people with SZ. Clozapine (CLZ) is the gold standard treatment; however, there are still patients who are non-responsive or partially responsive to treatment. Although a lack of evidence exists in reality, these patients are treated with a combination of agents in addition to CLZ. Therefore, this article reviews the prevalence of the augmentation of CLZ with additional agents. METHOD: This study was cross-sectional; physicians in a region of Australia in May 2011 were contacted to provide details of their patients on CLZ and any additional agents. The data set consists of 84 patients. RESULTS: The majority of the patients 84.5% were taking at least one additional agent. Of those taking additional agents, they derived from the following classes' antipsychotics (72%), antidepressants (30%), mood stabilisers (17%), antimetabolic agents (13%), benzodiazepines (7%), anticholinergics (4%) and miscellaneous agents (12.5%). CONCLUSION: It is apparent that CLZ is routinely augmented with other agents despite the lack of an evidence base. However, concerning was the lack of augmentation with antimetabolic agents despite the paucity of literature reporting the detrimental impact of antipsychotic treatment upon patients metabolic indices. The findings are discussed in the context of the current recommendations and empirical literature.

ABSTRACT

OBJECTIVE: Approximately 30% of individuals diagnosed with schizophrenia suffer from treatment-resistant or refractory schizophrenia. The gold standard for treatment of refractory schizophrenia is clozapine. However, a significant number of patients cease clozapine therapy; therefore this study explores patient's motives for cessation. METHOD: The motives for cessation and duration of clozapine treatment from a retrospective database of 151 patients with schizophrenia or schizo-affective disorder who had ceased clozapine once or more were reviewed, with the motives for cessation coded. The general motives for cessation were non-compliance, own decision, medical, poor response and other. In addition, the medical reasons for cessation were further codified: cardiac complications, neutropenia, fevers, other side effects and pregnancy. RESULTS: The majority of patients ceased clozapine owing to non-compliance with medical protocols or citing their own decision. Approximately half ceased after a period of 6 months or less. Seventeen per cent of patients ceased owing to medical reasons, with the largest proportions discontinuing treatment because of other side effects or neutropenia. CONCLUSION: Future research should seek to further investigate why patients decide to be non-compliant and formulate their own decision to cease treatment, as this will facilitate strategies to promote adherence amongst these two groups that are potentially the most amenable to change.
