The British Journal of Pharmacology (BJP) has published a new set of guidelines for reporting research involving animals, known as the 'ARRIVE' guidelines (Animals in Research: Reporting In Vivo Experiments). These guidelines aim to improve the reporting of animal studies, ensuring that experiments are conducted with ethical standards and that the results can be replicated. The guidelines were developed by the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) and are supported by several organizations, including the International Committee of Medical Journal Editors and the Council of Science Editors. The BJP and its parent organization, the British Pharmacological Society (BPS), emphasize the importance of clear and explicit reporting in scientific publications. They highlight that the guidelines are not just for pharmacology but apply to all fields of research involving animals. Key aspects relevant to pharmacology include the ethical treatment of animals, the use of anesthesia and analgesia, and the importance of detailed reporting to ensure reproducibility. BJP requires articles to comply with UK laws and ethical standards for animal experimentation. The journal encourages authors to follow the ARRIVE guidelines and provides advice on ethical and animal welfare issues. The BJP also invites feedback on the guidelines to further refine them and incorporate them into the Instructions to Authors. The ARRIVE guidelines are part of a broader effort to reduce the reliance on animal models and to promote more ethical and efficient research practices. The BJP and BPS are actively involved in discussions and symposiums on these topics, aiming to encourage informed debate and improve the quality of animal research.The British Journal of Pharmacology (BJP) has published a new set of guidelines for reporting research involving animals, known as the 'ARRIVE' guidelines (Animals in Research: Reporting In Vivo Experiments).
