Study hypothesis
Antipsychotic (neuroleptic) drugs remain central to the treatment of the symptoms of schizophrenia. Conventional drugs are effective in 70% of patients but have frequent neurological side effects. The atypical antipsychotics are a new class of drugs with a lower risk of these side effects and, in the case of clozapine, better efficacy. The cost of these new drugs is 20-30 times that of conventional drugs. There are currently no reliable data about their comparative effectiveness and cost-effectiveness in NHS settings in which to guide practice. If their use continues to expand, the annual drugs budget for schizophrenia in England will increase from £32 million to £240 million. A 4-centre, prospective, randomised, controlled trial is proposed, to evaluate the relative effectiveness of the new drugs compared to conventional drugs and to clozapine in a sample of 702 people with schizophrenia who are resistant to or intolerant of usual treatment. The trial will aim to demonstrate important differences in quality of life and other outcomes at 1 year, assess value for money and identify cost-effective management strategies.
