Expression of concern

The following article ‘Winstanley, P. The contribution of clinical pharmacology to antimalarial drug discovery and development. British Journal of Clinical Pharmacology 2003; 55: 464–8’ was an invited review based on a lecture, published online on 20 May 2003 on the Wiley Online Library. This article is a similar, but updated, version of an article previously published in The Lancet Infectious Diseases, ‘Winstanley, P. (2001), Modern chemotherapeutic options for malaria. The Lancet Infectious Diseases, 1: 242–50’. The Editor of BJCP is satisfied that, while the reduplication of text from the earlier article was not good practice, there is a difference between the earlier and later work. The author, editor and publisher apologize for this failure to follow normal publication practice.
