Study Notes

Good Manufacturing Practices (GMP)

  • GMP is a concern of the World Health Organization (WHO) since its inception.
  • The setting of global standards for food, biological, pharmaceutical, and similar products is required in Article 2 of the WHO Constitution.
  • The first WHO draft text on GMP was prepared in 1967.
  • The draft was submitted to the Twenty-first World Health Assembly under the title "Draft requirements for good manufacturing practice in the manufacture and quality control of drugs and pharmaceutical specialties" and was accepted.
  • The revised text was discussed by the WHO Expert Committee on Specifications for Pharmaceutical Preparations in 1968 and published as an annex to its twenty-second report.
  • The text was reproduced in 1971 in the Supplement to the second edition of The International Pharmacopoeia.
  • In 1969, the World Health Assembly recommended the first version of the WHO Certification Scheme on the Quality of Pharmaceutical Products Moving in International Commerce.
  • The 1992 revised draft requirements for GMP was presented in three parts: Quality assurance, GMP components/subsystems, and top management and production/quality control responsibilities.
  • GMP components/subsystems include hygiene, validation, self-inspection, personnel, premises, equipment, materials, and documentation.

Terms in GMP

  • Active pharmaceutical ingredient (API): Any substance or mixture of substances used in the manufacture of a pharmaceutical dosage form, becoming the active ingredient.
  • Authorized person: The person recognized by the national regulatory authority for ensuring each batch of finished product meets release requirements.
  • Batch (or lot): A defined quantity of starting material, packaging material, or product processed in a single process to maintain homogeneity.
  • Calibration: Establishing the relationship between measured values and a standard for weighing, recording, and controlling.
  • Clean area: An area with defined environmental control designed to minimize particulate and microbial contamination.
  • Contamination: The introduction of undesired impurities (chemical or microbiological) or foreign matter during production, sampling, packaging, storage, or transport.
  • Manufacture: All operations from material purchase to finished product distribution.
  • Marketing authorization (product license, registration certificate): A legal document defining the product's composition, formulation, and pharmacopoeial specifications.
  • Master formula: A document specifying starting materials, quantities, packaging materials, procedures, and precautions for a given product.
  • Production: All operations involved in preparing a pharmaceutical product from receipt to completion.
  • Qualification: Proving a process, system, or equipment meets expectations.
  • Quality assurance: All arrangements to ensure the quality of pharmaceutical products for intended use.
  • Quality control: The GMP part responsible for sampling, specifications, testing, and release procedures to ensure quality.
  • Specification: A list of detailed requirements used to evaluate quality during manufacture.
  • Standard operating procedure (SOP): A written procedure for tasks not necessarily specific to a product.
  • Starting material: Any substance used in the production of a pharmaceutical product, excluding packaging materials.
  • Validation: Proving that a procedure, process, equipment, material, activity, or system produces expected results.

Qualification and Validation

  • Each pharmaceutical company identifies qualification and validation for controlled aspects of operations.
  • A validation master plan documents qualification and validation protocols.
  • Validation establishes that premises, utilities, equipment, and processes meet GMP requirements.
  • Validation includes design, installation, operation, process, and performance aspects.
  • An ongoing validation program should maintain quality standards.
  • Validation is a defined GMP process involving documented studies.
  • Processes and procedures should be established according to validation results.
  • Validation of analytical methods, systems, and cleaning procedures are critically important.

Contract Production and Analysis

  • Contract production and analysis must be correctly defined, agreed, and controlled to avoid quality issues.
  • All contract arrangements, including proposed changes, must comply with the marketing authorization.
  • The contract giver can audit the contract accepter's facilities.
  • Final approval for release, in contract analysis, must be given by the authorized person.
  • The contract giver is responsible for assessing the competence and checking compliance with requirements.
  • The contract accepter avoids adversely affecting product quality.
  • A written contract defines responsibilities, detailing the procedures for releasing batches for sale and ensuring compliance with the marketing authorization.
  • Manufacturing, analytical, distribution records, and samples should be available to the contract giver.
  • The contract should specify handling procedures for starting materials, intermediate / bulk products, and finished products.

Assignment

  • Assignment questions include joint responsibilities of production and quality control heads and definitions of contract manufacturing and contract analysis.
