RT Journal Article SR Electronic T1 Are antipsychotic drugs the right treatment for challenging behaviour in learning disability?: The place of a randomised trial JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 338 OP 343 DO 10.1136/jme.27.5.338 VO 27 IS 5 A1 Richard Ashcroft A1 Bill Fraser A1 Michael Kerr A1 Zahir Ahmed YR 2001 UL http://jme.bmj.com/content/27/5/338.abstract AB People with learning disability sometimes display challenging behaviour. This can be managed by use of antipsychotic medication or behavioural therapy or both. There is no solid evidence, however, that these therapies are safe and effective. A randomised controlled trial of antipsychotic medication has been proposed to deliver such evidence. However, this presents difficult issues in the ethics of research with learning disabled people. In particular, is a trial the most efficient and fairest way to evaluate practice in this area? This paper reviews the clinical situation, gives the rationale for the trial, and analyses the ethical arguments for and against such a trial.
