Under section 21 of the Act, we are not required to provide information in response to a request if it is already reasonably accessible to you. The information you requested is available for 2005 from The Health and Social Care Information Centre (http://www.ic.nhs.uk/pubs/prescostanalysis2005) and for 2004 and previous years from the Department of Health (http://www.dh.gov.uk/PublicationsAndStatistics/Publications/PublicationsStatistics/PublicationsStatisticsArticle/fs/en?CONTENT_ID=4115886&chk=%2Bmewp3).
