Good Manufacturing Practices (GMPs)

Good Manufacturing Practices (GMPs)

CGMPs provide systems that assure proper design, monitoring, and control of manufacturing processes and facilities. 

Good Manufacturing Practices (GMPs) are the basic manufacturing and environmental conditions required to produce pharmaceutical products. They ensure that ingredients, products, and packaging materials are handled safely and that pharmaceutical products are processed in a suitable environment.

CGMP regulations assure the identity, strength, quality, and purity of drug products by requiring that manufacturers of medications adequately control manufacturing operations.

CGMP establishes strong quality management systems obtains appropriate quality raw materials, establishes robust operating procedures, detects and investigates product quality deviations, and maintains reliable testing laboratories.

GMPs address the hazards associated with personnel and the environment during pharmaceutical product manufacturing and packing. They provide a foundation for any pharmaceutical product’s safety, quality, purity, and effectiveness. 

As per ISPE – GMP regulations require a quality approach to manufacturing, enabling companies to minimize or eliminate instances of contamination, mix-ups, and errors.  This protects the consumer from purchasing a product that is not effective or even dangerous. Failure of firms to comply with GMP regulations can result in very serious consequences including recall, seizure, fines, and jail time.

HVAC SYSTEM AND TEST FOR HVAC QUALIFICATION

GMPs Address:

Environment Condition control (premises): location, design, and construction of the building and its interior, equipment, water supply

Personnel practices and behavior: personal hygiene, hand washing, clothing/footwear /headwear, injuries and wounds, evidence of illness, access, and traffic patterns, and chemical use.

Receiving, handling, storage, and Distribution: Written procedure for inspection of transport vehicles; loading, Unloading, and storage practices; inspection procedures for incoming products; shipping conditions; returned and defective products; allergen control; chemical storage; waste management.

Pest control: monitoring procedures for the exterior and interior of the building and the use of pesticides for pest Control and fumigation.

Sanitation: cleaning and sanitizing procedures and pre-operational assessment.

Equipment maintenance: procedures describing preventive maintenance and calibration of all the equipment and instruments that can affect product quality and safety. (like- thermometers, thermocouples, metal detectors, scales, and pH meters).

Recall and traceability: procedures that ensure final products are coded and labeled properly; Incoming materials; in-process and outgoing materials are traceable; recall system is in place and tested for effectiveness (procedures for mock recalls).

Water safety: water quality and safety. Monitoring procedures for raw water, purified water, Water for Injection and steam, and water treatment procedures that ensure it is potable for use in product manufacturing and cleaning.

Change Control

Components of GMPs:

GMP has two main components:

Written programs and implementation. Both are essential for the success of your product quality and safety.

Written programs are all the policies and procedures required to meet the standards listed in each GMP program. These include:

Policies and procedures (Like- standard operating procedures (SOPs), and standard testing procedures (STPs))

Monitoring procedures record keeping (Like – how records are kept and handled)

Implementation OF (GMPs)

Involves conducting the activities required to meet the standards and monitoring them.

To ensure the policies and procedures in your program are performed as described, you need to train your staff in these procedures. Ensure:

Training involves everyone in the facility and meets all employees’ requirements

Training is recorded (ex: who was trained, by whom, date, and type of training)

Staff is retrained when you modify your programs

To monitor your procedures:

Review procedures and record your observations (Like like-environmental controls checklist, and monitor personnel practices).

Review records to ensure they are completed properly and that appropriate corrective actions are documented.

Inspect and test for effectiveness (Like- perform microbial testing on cleaned and sanitized food contact surfaces to check the effectiveness of your cleaning and sanitizing procedures).

OBJECTIVE OF (GMPs)

Guarantee high-quality products to the consumer. Delivering products free of all possible contamination.

GENERAL REQUIREMENTS

Avoid risks and possibilities of a mix-up at all stages of Mfg., labeling Pkg and testing

AHUs, the comfort of the personnel working, and regular monitoring of temp & humidity, Particle Count, DOP testing, etc.

Proper drainage system which prevents backflow. Avoid open channels and if provided must be able to clean and disinfect.

Building & Facilities

  1. Design and construction features.
  2. Lighting.
  3. Ventilation, air filtration, air heating, and cooling.
  4. Plumbing.
  5. Sewage and refuse.
  6. Washing and toilet facilities.
  7. Sanitation.
  8. Maintenance

Good Manufacturing Practices

A basic principle of GMP is that quality cannot be tested into a batch of the product but must be built into each batch of the product during all stages of the manufacturing process.

It is designed to minimize the risks involved in any pharmaceutical production that cannot be eliminated through testing the final product.

Ten Principles of GMP

  1. Design and construct the facilities and equipment properly
  2. Follow written procedures and Instructions
  3. Document work
  4. Validate work
  5. Monitor facilities and equipment
  6. Write step-by-step operating procedures and work on instructions
  7. Design, develop and demonstrate job competence
  8. Protect against contamination
  9. Control components and product-related processes
  10. Conduct planned and periodic audits

Do and Don’t of GMP

Hygiene

All employees working in direct contact with food, food contact surfaces, and food packaging must conform to hygienic practices. This protects against food contamination by microorganisms or unwanted material.

Hygiene and Communicable Diseases

  • clothing
  • hair
  • personal habits
  • hand washing
  • personal effects and jewelry
  • illness and disease
  • injuries
  • visitors
  • training

GMPs

Employees Shall be –

  • Bathe daily
  • No perfume, aftershave, or fragrant creams
  • No jewelry
  • No false nails or nail polish
  • Fingernails should be trimmed short
  • Use metal-detectable bandages covered with gloves
  • No eating, drinking, or chewing gum

Hand washing

All employees must wash their hands thoroughly:

  • when they enter food-handling areas
  • before starting work
  • after handling contaminated materials
  • after breaks
  • after using toilet facilities

Personnel 

  • Do not leave gloves, masks, etc. lying around while on break or at shift end.
  • Crates, boxes, containers, or buckets must not be placed directly on the floor.
  • Store brooms and dust pans at the stations provided.

Why GMP is important

  • A poor quality medicine may contain toxic substances that have been unintentionally added.
  • A medicine that contains little or none of the claimed ingredients will not have the intended therapeutic effect.

Some of the main risks are –

  • Unexpected contamination of products, causing damage to health or even death.
  • Incorrect labels on containers could mean that patients receive the wrong medicine.
  • Insufficient or too much active ingredient, resulting in ineffective treatment or adverse effects.
