Study Notes

CGMP for Finished Pharmaceuticals

CGMP regulations were established by the Food and Drug Administration (FDA)
These regulations ensure premium standards for drug product quality.

Definitions

Active Pharmaceutical Ingredient (API): Any ingredient intended to furnish pharmacological activity or other direct effects in the diagnosis, mitigation, prevention, or cure of a disease.
Component: Any ingredient used in a drug product.
Drug Products: Finished form that contains active drug & inactive ingredients.
Quality Control: The regulatory process through which the industry measures and compares the actual industry performance with the set standards.
Quality Control Unit: A department in the industry made to ensure the quality of the drug formed.
Quarantine Area: A specified area for ingredients to be placed/stored before acceptance testing and qualification for use.

Organization & Personnel

The personnel section deals with the responsibilities of quality control.
Employees and consultants in the quality control unit have the authority to accept or reject a drug product formed.
Packaging and labeling may affect drug product quality.

Buildings & Facilities

Regulations in this section include design, structural features, and functional aspects of buildings and facilities for drug manufacturing.
The place for drug manufacturing must be clean.
Other factors to consider include water quality standards, security, materials used in ceilings, and floors, lighting and walls.
Production storage, handling of waste, heat, humidity, and ventilation must be present in the building.

Equipment

Each piece of equipment must be appropriate size and at the appropriate position for its intended use.
Standard operating procedures must be written for cleaning each piece of equipment.
Automated equipment must be calibrated daily.

Production & Process Control

Written procedures are required to control production processes to ensure the drug product has correct identity, strength, and quality and purity.
Any deviation from the written procedures must be recorded and justified.
Automated equipment should be controlled and validated / calibrated regularly.

Packaging & Labeling Control

Procedures are required to receive, identify, package, and label drug products.
Labeling for each drug variation (strength, dosage form, or quantity of contents) must be separated.
Materials must be stored only by authorized personnel.
Labeling and packaging must be withheld for use until the packaging is approved and released by the quality control unit.
The quantities issued must be reconciled and investigated.
Each label must meet the requirements for the product batch number and expiration date.

Expiration Dating

To ensure that the drug product meets the applicable standards of purity, strength, and quality at the time of use, it must have an expiration date.

Laboratory Controls

Laboratory controls are the requirements for the establishment of standards, sampling plans, test procedures, and other mechanisms for the specification of the drug product which applies to each batch.
The specifications include provision for sample testing intervals, sample storage, stability testing, and special testing requirements for certain dosage forms, including parenterals, ophthalmics, and controlled-release products.

Records & Reports

Control and distribution records for production must be maintained for at least one year.
This includes equipment cleaning, maintenance logs, raw materials, and product containers and closures and labels.
Complete master production control records for each batch must be kept.

Manufacturing of Sterile Products

Sterilization is the process of killing bacteria, all other forms of living organisms, and their spores.
Sterilization methods include physical methods (dry heat, moist heat, radiation) and chemical methods (ethylene oxide, formaldehyde, hydrogen peroxide).

Physical Methods of Sterilization

Dry Heat: Used to sterilize items, but requires more time and high temperature.
Substances Sterilized: Liquid paraffin, fixed oils, petroleum, propylene glycol, and powders.
Moist Heat: Most reliable method for sterilization. Bacteria are destroyed at relatively low temperatures.
Used for sterilization of equipment and instruments.
Mechanism: Destroys microbes by denaturation and coagulation of proteins.

Methods for Dry Sterilization

Flaming: A simple method for sterilization using a hot part of a bunsen burner flame for short periods.
Hot Air Oven: Sterilization in a chamber of metal, heated electrically, and controlled by a thermostat

Incineration

A method to dispose of contaminated materials to ash.
Used to dispose of biohazard and medical waste.

Moist Heat Sterilization

The most reliable method of sterilization, using moist heat (boiling water).
The mechanism kills microorganisms by coagulation and protein denaturation.
Microorganisms are killed at relatively low temperatures.
Methods include Autoclaving (pressure steam sterilization)

Methods for Moist Sterilization (autoclaving)

Autoclaving uses steam under pressure to sterilize items.

Heating with Bactericide

A method of sterilization where bactericide is added to the suspension and the sealed containers are heated for a controlled time.

Sterilization by Radiation

A method of cold sterilization, using radiation to kill microorganisms.
A widely used method of sterilization for medical equipment and items.

Gamma Rays

Very penetrating radiation.
Used to sterilize disposable medical equipment, syringes, and needles.

UV Light

Used for sterilization of surfaces and transparent objects.
Effective for sterilizing biological safety cabinets.

Electron Beam Processing

A high-dose radiation method used for medical devices.

Chemical Sterilization

Chemicals are used when heat is not suitable.
Examples include ethylene oxide, ozone, formaldehyde, hydrogen peroxide, and chlorine bleach.
Ethylene oxide is highly flammable and takes longer than heat sterilization.

Preservatives

Agents used to inhibit the growth of microorganisms in foods.
They should be non-toxic if consumed.

Antimicrobial Agents

Chemicals that kill or inhibit the growth of microorganisms.
Antiseptics are applied to the skin and mucous membranes, while disinfectants are applied to inanimate objects.

Prions

Highly resistant to chemical sterilization.
Treatment with aldehyde increases prion resistance.

Control of Microbial Contamination

Steps to prevent microbial contamination including risk assessment and hazard analysis of critical control points (HACCP)
Environmental cleanliness and hygiene
Quality of starting materials
Water quality and storage processes
