GMP Requirements in Pharmaceuticals | Complete Compliance Guide

A key responsibility of the pharmaceutical sector is ensuring that they manufacture safe, effective and consistently produced medicines. Pharmaceutical companies achieve this through their compliance with Good Manufacturing Practices (GMP), which are regulatory frameworks, principles and guidelines used to regulate the manufacture, testing and distribution of drug products.

Many different countries around the world have regulatory authorities that enforce GMP regulations including the FDA, WHO and EMA. These authorities hold pharmaceutical manufacturers to high standards to safeguard the health and safety of patients.

This article outlines what are the requirements for GMP in pharmaceuticals and how organizations can successfully implement GMP requirements in their organizations.

What is GMP in Pharmaceuticals?

Good Manufacturing Practices (GMPs) are a set of standards to ensure that every product is manufactured and checked to the same level of quality on an ongoing basis.
All methods of producing goods through GMPs include:

• Raw Material
• Equipment
• Personnel
• Documentation
• Facilities
• Production Process

The purpose of GMPs is to reduce the potential risk of producing a product without testing as the only way to ensure that the product is of high quality and safe.

Why GMP is Important

There are many reasons why compliance with a GMP is so critical:

• Protecting patients from harm by providing safe to use products
• Ensuring consistent quality from batch to batch
• Preventing errors and contamination of the final product
• Giving the consumer and regulators confidence in the products
• Minimizing the possibility of receiving penalties e.g., product recalls and regulatory penalties

Without implementing GMPs, you run a high risk of producing non-compliant medicines.

Key GMP Requirements in Pharmaceuticals

1. Quality Management System (QMS)

GMP compliance is heavily reliant on having a solid QMS.
The QMS consists of:

• Deviation Management
• Corrective and Preventative Action
• Change Control
• Complaint Handling
• Risk Management

Guidelines like ICH Q10 Pharmaceutical Quality System stress the need for an integrated quality system. When a QMS functions well, it allows for continual improvement while also enforcing effective control over all quality-related activities.

2. Personnel & Training

Personnel are the most important part of GMP.
Requirements for personnel include:

• Qualified and trained personnel
• Defined role & duty expectations
• On-going training to remain up-to-date
• Good hygiene & gowning techniques

Employees need to understand GMP principles as well as adhere to procedures consistently. Failure to properly train your personnel will cause errors, contamination and compliance issues.

3. Premises & Equipment

The design, maintenance and operation of facilities and equipment must be such that they do not introduce contamination into the product and do not compromise the quality of the product.
Key items include:

• Facilities with proper layouts and separation of areas
• Facilities that are clean and properly maintained
• Qualified Equipment (IQ, OQ and PQ)
• Regular calibration and maintenance of equipment

Good design of a facility will enhance the efficiency of the workflow and will minimize errors.

4. Documentation and Records Management

An essential aspect of GMPs is the documentation of all operations. One of the key principles for GMPs is that “All work/activities shall be documented”.
Common types of documents include:

• SOPs (Standard Operating Procedures)
• Batch manufacturing records
• Logbooks
• Validation reports

The records must also adhere to the ALCOA+ principles:

• Attribute
• Legible
• Contemporary
• Original
• Accurate

Having proper documentation will assure as well as provide traceability and accountability, for all work completed.

5. Production and Process Controls

Manufacturing processes must be documented/defined in addition to documented evidence that they have been validated and controlled. Documentation required for this includes:

• Approved manufacturing procedures
• In-Process controls
• Verifying and monitoring of critical parameters
• Preventing cross-contamination

The documentation provides evidence of how well the process continues to consistently produce products which meet product specifications.

6. Quality Control (QC)

Quality Control (QC) ensures that all aspects of raw materials, intermediate materials and/or products meet all recognized standards or specifications of the type of product involved.
Examples of QC activities include:

• Sampling/testing
• Analytical method validation
• Performing stability studies
• Performing OOS (Out of Specification) investigations

QC Laboratories are to be set up such that they do not have any possible ties with the manufacturing areas.

7. Validation and Qualification

Validation and qualification are two parts of the same process that are used to verify that processes or systems continue to work the way they should. There are many different types of validations, which include Process Validation, Cleaning Validation, Analytical Method Validation and Computer System Validation.

There are also equipment qualification (IQ, OQ and PQ), receiving data for part when you buy something new. Validation verifies your reliability and consistency.

8. Material Management

Materials and packaging materials must be managed properly to make sure that your finished product is of a high quality. Examples of how to control material and packaging materials include:

• Vendor qualification
• Incoming material testing
• Properly stored as defined by the manufacturer
• Inventory control

Traceable and well labelled as defined by company policies

9. Cleaning and Sanitation

If cleaning procedures are not clearly defined, it will cause contamination. To help in controlling this, the following is required:

• Defined Cleaning Procedures
• Using Cleaning Agents as defined by the Manufacturer
• Validation of Cleaning Procedures - completed after every use
• Regular Monitoring of cleaning procedures - done frequently when cleaning is done.

If these things are followed, the manufacturing facility will be a clean and sanitary environment.

10. Handling of Deviations and CAPA

All deviations should be recorded, investigated and acted upon.
A CAPA system will:

• Identify the root cause
• Implement corrective actions
• Prevent reoccurrence

An effective CAPA system supports a quality system.

11. Complaints and Recalls

Companies must have processes for managing complaints and recalls.
This includes:

• Investigating all customer complaints
• Evaluating the impact of product quality
• Defective product recall process

Taking timely action will protect the patient's health and build trust.

12. Self-Inspections and Internal Audits

Conducting regular self-inspections will allow you to identify nonconformities with GMPs.
Internal audits should:

• Include all departments
• Be conducted at least annually
• Include sufficient corrective actions

Self-inspections assist to prepare the facility for a regulatory audit.

Regulatory Framework for GMP

Current regulations governing Good Manufacturing Practice (GMP) will be provided by the respective governmental entities with jurisdiction over the area.
The major forms of guidance applicable to GMP according to the FDA include the following:

• Current Good Manufacturing Practice by the FDA
• WHO guidelines for GMP
• EU guidelines for Good manufacturing practices

These forms of guidance will provide the appropriate detailed requirements for both pharmaceutical manufacturing and quality systems.

Common GMP Violations

The most common violations of GMP's outline of procedures are:

• Inadequate documentation
• Inadequate training
• Lacking process validation
• Integrity of data issues
• Inadequate investigating

Each of these examples of noncompliance can result in the issuance of a warning letter or product recall and even the closing of a facility.

Best Practices for GMP Compliance

Companies that produce pharmaceuticals should establish and maintain a strong quality culture with their personnel involved in GMP compliance through the following practices:

• Training programs are held on a continual basis
• Conducting risk assessments based on their individual organizational requirements and implementing a digital information system to manage all data related to GMP
• Using KPI monitoring processes to relay the results of their science throughout the company

The most essential factor to continuously being in compliance with GMP is continued improvement.

Future Trends in GMP

Global Manufacturing Practices (GMP) are changing with technology. The following are trends that will shape these changes:

• Automation and robotics
• Digitized quality systems (eQMS)
• Real-time monitoring via sensors
• Utilizing data analytics and artificial intelligence

These tools will allow companies to have greater efficiency and compliance within their GMP operation.

The base of pharmaceutical production is based upon good manufacturing practices (GMPs); to provide a product that is safe, of good quality and effective.

Pharmaceutical companies can accomplish and maintain GMP compliance through the implementation of robust quality systems with documentation, validating productive processes and educating all personnel.

In an extremely regulated environment, adhering to GMPs is not only required by law; it is also a commitment to providing a product that ensures patients are provided with safe and effective products.
