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) [https://www.who.int/medicines/services/inn/en/ 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.
