Drug bulletins are specialised periodicals providing comparative information and advice on the prescribing and use of medicines. Doctors and pharmacists are the primary audience for most drug bulletins. Some bulletins, however, are read by a broader range of health professionals, including nurses and community health workers, and a few reach the general public. The aim is to provide practical, reliable information about medicines and promote more rational, informed decisions about their use. Although the main focus of most bulletins is on improving individual prescribing decisions, many also deal with broader policy issues.
