    Study Notes

    Good Manufacturing Practices (GMP)

    • GMP is a system to consistently produce and control products (drugs) according to quality standards.
    • It minimizes risks that can't be eliminated during testing, such as contamination.
    • Risks include incorrect labels, wrong medicine, insufficient/too much active ingredients, and contamination.
    • GMP applies to all production steps, beginning with materials, premises and equipment to staff training.
    • Detailed, written procedures for each GMP-related process are critical.
    • Documentation of consistent procedures at every stage of production is crucial.
    • WHO established GMP guidelines.
    • Many countries have formulated their own GMP requirements.

    Early Beginnings of GMP

    • Early 1900s saw house calls, home remedies, ointments, and "miracle elixirs."
    • No regulations existed until 1902.
    • Exposure of unsanitary meatpacking plants (1905) by Upton Sinclair increased public awareness.
    • The 1906 Pure Food and Drug Act, created the earliest regulations requiring truthful labelling.

    1941 Initiation of GMP

    • Sulfathiazole tablets contaminated with phenobarbital led to 300 deaths/injuries (1941).
    • FDA enforced revisions of manufacturing and quality control.
    • Thalidomide tragedy (thousands of birth defects) strengthened regulations regarding human experimentation and drug approval.

    GMP Guidelines

    • Components like personnel, premises, equipment, sanitation & hygiene, documentation, quality control, and complaints are crucial.

    Areas to be Covered

    • Personnel (Experienced, Adequate Number, Job Descriptions, Trained)
    • Health (Diseases, Open Lesions)
    • Premises (Location, Design, Construction, Hygiene)
    • Equipment (Location, Material, Calibration, Cleaning)
    • Sanitation & Hygiene (Written Procedures, Practices, Clothing)
    • Warehousing Area
    • Reference Samples
    • Validation and process validation
    • Labels And Other Printed Materials
    • Quality Control

    Personnel

    • Qualified and experienced personnel.
    • Sufficient staff numbers.
    • Well-defined job descriptions and training.
    • Health checks (disease, open lesions) are essential.
    • Personnel should be trained on GMP principles that affect them.
    • Personnel must be qualified with appropriate education and responsibilities in writing.
    • Should practice good sanitation and health habits
    • Personnel should wear suitable clothing for manufacturing activities
    • Avoiding direct contact with intermediates or active ingredients
    • Restrictions on smoking, eating, drinking, chewing and storage of food.
    • Those suffering from infections/diseases should not engage in activities.

    Premises

    • Location: Minimizes cross-contamination risks. Addresses geography, climate and economic factors. Minimizes risk from neighbours.
    • Design: Maximum protection against insects, birds, and animals. Designated areas (production, quality control, weighing, storage, ancillary).
    • Construction: Prevent cross-contamination, dust control, easily cleanable surfaces, proper air supply, use of HEPA filters (High-Efficiency Particulate Air filters), smooth impervious surfaces (floors, walls, and ceilings).
    • Hygiene considerations: Prohibit eating, drinking, and smoking in production areas.

    Equipment

    • Equipment must be appropriate for its intended use (appropriate range, precision, and accuracy)
    • Non-reactive materials for equipment surfaces that come into contact with drugs.
    • Minimizes risks of contamination from lubricants, dust, and other foreign materials.
    • Layout should facilitate easy cleaning and prevent cross-contamination.
    • Maintenance records are kept.

    Sanitation

    • Written procedures, hygiene, health and clothing practices.
    • Waste disposal procedures.
    • Practices not permitted (eating, smoking, unhygienic practices).
    • Clothing requirements (grade D and grade C).
    • Sanitation regulation demands written sanitation programs developed and overseen by qualified personnel.
    • Cleaning procedures, cleaning intervals, and disinfection (product application, dilution, and equipment).
    • Procedures for waste material and debris, pest control, rodenticides, insecticides, and fumigation.

    Verification, Qualification, and Validation

    • Operational methods and procedures in manufacturing and testing are validated to ensure intended functionality.
    • Validation activities conducted according to approved protocols and appropriate guidance.
    • Process validation builds product quality, safety, and effectiveness into the final product.

    Process Validation

    • Commercial processes are based on knowledge gained during development and scale-up.
    • Process qualification confirms the process's ability to produce reproducible products.
    • Process verification ensures continuous process control throughout routine production.

    Method Validation

    • Each method used to analyze the drug substance (product identity, strength, purity, and potency) must have associated validation.

    Key GMP Concepts

    • Applicability of GMPs for production of innovator and generic drugs.
    • GMP requirements for marketed products and clinical trial supplies including placebos.
    • Maintaining product quality cannot be tested into, it must be built in through facility, equipment design, and production.
    • GMPs (Good Manufacturing Practices) are continually updated or changing.

    Storage Areas

    • Storage capacity for various drug materials (starting, packaging, intermediates, bulk, quarantined, released, rejected, recalled).
    • Clean, dry, well-lit, and temperature-controlled storage.
    • Receiving and dispatch areas to protect materials from weather.
    • Special storage for temperature-sensitive or high-risk materials (narcotics, radioactives, highly active materials).
    • Separate areas for rejected, recalled, or returned materials.
    • Separate sampling areas.

    Quality Control Areas

    • Separate quality control labs from production areas with appropriate space.
    • Adequate storage for samples, standards, solvents, and records.
    • Separate areas for instruments to reduce external contamination.

    Ancillary Areas

    • Separate rest, refreshment, and facilities for cleaning/changing.
    • Dedicated maintenance workshop or storage areas for tools and parts away from main production.
    • Animal housing well-separated.

    Working areas are well-lit

    Heating, ventilating, and air conditioning systems.
