The development of pharmacopoeial standards receives input from relevant industries, hospitals, academia, professional bodies and governmental sources, both within and outside the UK. The British Pharmacopoeia Laboratory provides analytical and technical support to the "British Pharmacopoeia". Its major functions are:  The current edition of the "British Pharmacopoeia" is available from The Stationery Office Bookshop. Detailed information and guidance on various aspects of current pharmacopoeial policy and practice is provided in supplementary chapters of the "British Pharmacopoeia". This includes explanation of the basis of pharmacopoeial specifications, and information on the development of monographs including guidance to manufacturers. British Approved Names (BANs) are devised or selected by the British Pharmacopoeia Commission (BPC), and published by the Health Ministers, on the recommendation of the Commission on Human Medicines, to provide a list of names of substances or articles referred to in Section 100 of the Medicines Act 1968. BANs are short, distinctive names, for substances; where the systematic chemical or other scientific names are too complex for convenient general use. As a consequence of Directive 2001/83/EC, as amended, the British Approved Names, since 2002, may be assumed to be the recommended International Non-proprietary Name (rINN), except where otherwise stated. A World Health Organization (WHO) INN identifies a pharmaceutical substance or active pharmaceutical ingredient by a unique name that is globally recognised, and in which no party can claim any proprietary rights. A non-proprietary name is also known as a generic name. There are equivalent pharmacopoeia in many other countries, such as U.S. (the "United States Pharmacopoeia"), Japan ("Japanese Pharmacopoeia"), and China ("Pharmacopoeia of the People's Republic of China"), and the World Health Organization maintains "The International Pharmacopoeia". The "British National Formulary" (BNF) and its related publications contains information on prescribing, indications, side effects and costs of all medication drugs available on the National Health Service (NHS).
