Generic medicines are medicines marketed without a brand name.
The April 2005 Drug Tariff introduced a new Category M of generic medicines under Part VIII, which applies to some medicines previously in Category A. The basic prices of Category M medicines reflect the average manufacturers' market prices after discount rather than the Category A system of basket prices before discount. Under these two voluntary Schemes (M and W) backed by section 261 of the National Health Service Act 2006, data will be provided by scheme members to quarterly revise Category M prices. Scheme M will apply to manufacturers and Scheme W will apply to wholesalers.
