This document discusses batch manufacturing records (BMRs), which are necessary quality and GMP documentation used to trace the complete manufacturing cycle of a batch or lot of a product. A BMR contains information about the batch including the batch number, size, composition, manufacturing record, weight of drug, shelf life, and storage conditions. It also includes general manufacturing instructions, a cleaning record of equipment used, a bill of materials listing raw materials, step-by-step manufacturing process details, yield calculations, a list of abbreviations, and a history of changes made to the document. A good BMR format contains all of this essential information.
