Master Formula Record (MFR) MCQs With Answer

Introduction: Master Formula Record (MFR) is a cornerstone document in pharmaceutical manufacturing that defines the composition, stepwise procedures, in-process controls, equipment, and packaging instructions necessary to produce a defined pharmaceutical product consistently and in compliance with GMP. This blog presents focused MCQs with answers designed for M.Pharm students studying Documentation & Regulatory Writing. The questions probe deeper into practical and regulatory aspects of MFRs: content expectations, tolerances, scaling, change control, record keeping, and interactions with QA/QC. Use these MCQs to test your understanding of how a robust MFR supports product quality, traceability, and regulatory compliance in a manufacturing environment.

Q1. What is the primary purpose of a Master Formula Record (MFR)?

• Sales forecasts for the next quarter

Correct Answer: Batch size, complete ingredients with quantities, manufacturing steps, in-process controls and packaging instructions

Q3. How does a Master Formula Record (MFR) differ from a Batch Manufacturing Record (BMR)?

• MFR is used only for packaging while BMR is for manufacturing
• MFR is the authorised template/specification; BMR is the executed record capturing actual values for a particular batch
• MFR contains only supplier data and BMR contains only QC results
• There is no difference; they are interchangeable terms

Correct Answer: MFR is the authorised template/specification; BMR is the executed record capturing actual values for a particular batch

Q4. In an MFR context, what is the definition of theoretical yield?

• The maximum quantity expected based on formulation calculations assuming no losses
• The actual weight measured at packaging
• The minimum acceptable product quantity after packaging
• The weight of empty containers used

Correct Answer: The maximum quantity expected based on formulation calculations assuming no losses

Q5. Why are yield tolerances specified in the MFR?

• To allow unlimited product loss during manufacture
• To define acceptable deviation limits between theoretical and actual yields and trigger investigations when exceeded
• To set marketing prices
• To identify preferred suppliers

Correct Answer: To define acceptable deviation limits between theoretical and actual yields and trigger investigations when exceeded

Q6. What are in-process controls (IPCs) as specified in an MFR?

• Final release laboratory tests only
• Routine checks and measurements at defined manufacturing stages to monitor critical quality attributes and process performance
• Administrative audits of production staff
• Financial controls for procurement

Correct Answer: Routine checks and measurements at defined manufacturing stages to monitor critical quality attributes and process performance

Q7. When scaling an MFR to a different batch size, which principle must be applied?

• Proportionally adjust ingredient quantities and validate critical process parameters and equipment suitability for the new scale
• Change only the batch number and leave quantities unchanged
• Multiply all times by two irrespective of equipment
• Remove all in-process controls to simplify production

Correct Answer: Proportionally adjust ingredient quantities and validate critical process parameters and equipment suitability for the new scale

Q8. Who is primarily responsible for approving the Master Formula Record in a GMP environment?

• Sales manager
• Quality Assurance (QA) department
• External auditor only
• Cleaning crew supervisor

Correct Answer: Quality Assurance (QA) department

Q9. How should changes to a Master Formula Record be controlled?

• By informal verbal consent between operators
• Through a formal change control procedure documenting rationale, impact assessment, approvals and revision history
• By editing the document without trace of previous versions
• By sending an email to a single person without approval

Correct Answer: Through a formal change control procedure documenting rationale, impact assessment, approvals and revision history

Q10. What information does a batch number in the MFR/BMR typically provide?

• Unique identification allowing traceability of manufacturing date, site and specific production run
• Only the product price
• Employee salary details
• Marketing region code only

Correct Answer: Unique identification allowing traceability of manufacturing date, site and specific production run

Q11. Which of the following items would NOT normally be included in an MFR?

• Stepwise manufacturing instructions and critical parameters
• List of raw materials and their specifications
• Detailed employee performance appraisals
• Packaging and labelling instructions

Correct Answer: Detailed employee performance appraisals

Q12. How should Critical Process Parameters (CPPs) be presented in the MFR?

• As vague suggestions without target ranges
• With defined target values or ranges, monitoring frequency and acceptance criteria
• Omitted entirely to avoid over-specification
• Only in a separate confidential file not linked to the MFR

Correct Answer: With defined target values or ranges, monitoring frequency and acceptance criteria

Q13. What is the correct way to reference cleaning requirements in an MFR?

• Include validated cleaning procedure references and clear instructions for equipment cleaning and verification; keep validation reports as separate documents
• Do not mention cleaning at all
• List only the cleaning chemicals without procedures
• Require cleaning only after every ten batches with no documentation

Correct Answer: Include validated cleaning procedure references and clear instructions for equipment cleaning and verification; keep validation reports as separate documents

Q14. Why is a revision history section important in an MFR?

• To hide previous mistakes
• To track document changes, reasons, approval signatures and ensure use of the correct current version
• To list all operators who read the document
• To store marketing materials

Correct Answer: To track document changes, reasons, approval signatures and ensure use of the correct current version

Q15. How should actual weights and volumes be recorded in the BMR derived from an MFR?

• Approximate values without operator identification
• Exact measured values to specified precision with date/time and operator initials or signature
• Only the theoretical values as per the MFR
• As a range without specification

Correct Answer: Exact measured values to specified precision with date/time and operator initials or signature

Q16. What is the purpose of label reconciliation as specified by the MFR or related procedures?

• To ensure the number of labels printed, issued and applied matches production and to detect any missing or extra labels
• To determine label artwork colors
• To decide the marketing slogan for the product
• To count employee badges

Correct Answer: To ensure the number of labels printed, issued and applied matches production and to detect any missing or extra labels

Q17. What should an MFR specify regarding sampling and testing of a batch?

• Sampling locations, sample sizes, tests to be performed, acceptance criteria and timing in accordance with approved SOPs and specifications
• Only final product tests, excluding in-process sampling
• That testing is optional
• Only the name of the testing laboratory without details

Correct Answer: Sampling locations, sample sizes, tests to be performed, acceptance criteria and timing in accordance with approved SOPs and specifications

Q18. Under what conditions is reprocessing of a batch acceptable according to good documentation practice described in an MFR?

• Reprocessing is allowed without documentation whenever convenient
• Only when permitted in the MFR/SOP, justified, authorized and documented with a full impact assessment and QA approval
• Reprocessing should never be allowed under any circumstance
• When production staff decide informally during a shift

Correct Answer: Only when permitted in the MFR/SOP, justified, authorized and documented with a full impact assessment and QA approval

Q19. Which statement best explains the relationship between MFR and specifications?

• MFR is unrelated to product specifications
• MFR operationalizes product specifications by providing steps, materials and controls needed to meet the defined specifications
• Specifications are optional details in the MFR
• MFR replaces the need for any specifications
