WHAT IS BMR ( BATCH MANUFACTURING RECORD )?
Batch manufacturing record is a
written document of the batch that is prepared during the pharmaceutical
manufacturing process. It contains actual data of the batch manufacturing and
whole manufacturing process step by step.
There are several stages of the
pharmaceutical tablet manufacturing process. All stages are included in the
batch manufacturing record from issuance of the raw material to the final
packaging. Every batch has a separate BMR having the batch history of batch
production. Documents and the proofs are attached in the BMR during the
manufacturing process.
A good Batch Manufacturing Record format
should contain following parts:
1. Batch Record:
Very first page of the BMR has all records about the batch as batch number,
batch size, composition, master formula record referred, weight of the batch,
shelf life, storage conditions, manufacturing license number, manufacturing
date, expiry date, date of starting and date of completion.
2. General Instruction for Manufacturing: Health and safety instructions to the operators and the
manufacturing chemist are written those should be followed during the
manufacturing process regarding the material and equipments used during
manufacturing.
3. Equipment Cleaning Record: Checklist of the cleaning of all equipments is prepared;
those are used in the manufacturing of the batch including the previous
product, batch and date of cleaning. Cleaning of the equipments should be
checked by the quality assurance.
4. Bill of Materials:
List of the raw material should have the quantity of the materials with their
AR numbers. Weights of the materials should be verified by quality assurance.
If tablets are coated then coating material should be included.
5. Manufacturing Process: Manufacturing process should be written step by step in
easy language. Milling, sifting, drying, lubrication, compression, coating and
packing having all instruction with process time should be written. Checklist
for line clearance should also be attached before starting every process.
After completion of the every stage, tablets must be checked
for the compliance of the specification of that stage. Results should be
attached with the batch manufacturing record.
6. Yield:
Yield of the batch should be calculated at the end of every stage to calculate
the process loss. Final yield should be calculated at the end of the
manufacturing that should not be less than 99.00%.
7. Abbreviations:
List of the abbreviations used in the document should be made to understand the
BMR easily.
8. History of Chances: At the end, the document should have a list of the changes
in the document including the revision number and the date of the change.
