text: European Union legislation from 2001 required harmonisation of the BP with the European Pharmacopoeia (EP), as well as the adoption of International Nonproprietary Names through directives (2001/82/EC and 2001/83/EC, as amended, and 2003/63/EC). Across the EU has meant that, with the notable exception of adrenaline/epinephrine, BANs are now the same as the INNs. For example, the old BAN methicillin was replaced with the current BAN meticillin, matching the INN.
  This has resulted in an interesting situation in other countries that use BANs. While the British Pharmacopoeia and BANs are the official pharmacopoeia/names defined by legislation in many of these countries, the former BANs often continue to be used, purportedly because of the difficulty of changeover.  Despite the importance of the BP, there appears to be little or no movement in the direction of changing these names. In Australia, the Australian Approved Names are generally the same as BANs, but a few exceptions remain.
