By harmonizing the gold standard of WHO GMP with India's enhanced Schedule M, the Indian pharmaceutical industry is poised to become a global leader, delivering safe, trusted, and world-class medicines worldwide.

Introduction
Good Manufacturing Practices (GMP) are the foundation of quality in the pharmaceutical industry. They ensure that every medicine is consistently safe, effective, and of high quality. This commitment to excellence protects public health and builds trust in medicines worldwide.
Globally, the World Health Organization (WHO) provides comprehensive GMP guidelines. The most important ones are TRS 986 Annex 2 for general GMP and TRS 1044 Annex 2 for sterile medicines. These guidelines are international benchmarks, especially important for companies that export medicines.
In India, GMP standards are outlined in Schedule M of the Drugs and Cosmetics Rules, 1945. A major update on December 28, 2023, by the Department of Health and Family Welfare, brought Indian GMP standards much closer to the WHO framework. While this update aligns India with global best practices, companies still need to follow specific Indian compliance rules.
For pharmaceutical companies in India or those exporting from India, understanding the differences between WHO GMP and Indian GMP is crucial. It's not just about following the rules; it's essential for competing in the market and being ready for global trade. Walter Healthcare offers expert guidance and solutions to help companies comply with both sets of regulations.
This blog post will simplify these complex rules by looking at their similarities, highlighting key differences, explaining how to put them into practice, and detailing the steps to get certified. Our goal is to provide a practical comparison that helps your pharmaceutical operations achieve and maintain the highest quality standards.
Understanding Good Manufacturing Practices
Good Manufacturing Practice (GMP) is a quality system that guarantees products are consistently manufactured and controlled to established standards. Its purpose is to mitigate risks inherent in pharmaceutical production that cannot be entirely removed through final product testing.
GMP goes beyond final product testing by preventing errors, contamination, and quality failures throughout every stage of production. It applies to:
Strategically sourcing and meticulously handling raw materials
Innovatively designing facilities and state-of-the-art equipment
Empowering personnel through comprehensive training and upholding impeccable hygiene standards
Maintaining meticulous documentation and robust record-keeping
Implementing rigorous process validation and stringent quality control
Ensuring the safest packaging, precise labeling, and efficient distribution
History of GMP
The concept of Good Manufacturing Practice was not developed overnight; rather, it has evolved over decades, with different public health crises, regulatory reforms, and global harmonization efforts and their responses. This is a chronological history of Good Manufacturing Practice (GMP), detailing its evolution through public health crises, regulatory shifts, and international cooperation, all supported by official references.
Roadmap of GMP

This U.S. legislation was the first major step in fighting tainted and misleading food and drugs, beginning formal drug regulation. While it didn't set manufacturing standards, it started a crucial public conversation about controlling what was being consumed.
1930s- Tragedy Drive
1937- The Sulfanilamide Disaster (USA) The tragic deaths of over 100 people, many of them children, due to a sulfanilamide preparation dissolved in diethylene glycol (DEG), marked a critical juncture in global drug safety. This event unequivocally demonstrated that assumptions cannot be relied upon in drug safety and underscored the vital importance of stringent oversight in drug production.
In response, the U.S. enacted the Federal Food, Drug, and Cosmetic Act in 1938. This legislation mandated that drug manufacturers prove the safety of their products before bringing them to market.
1960s- Global Drug Disasters Shape Modern GMP
Initially sold for morning sickness and as a sedative, thalidomide caused a global disaster with over 10,000 babies born with severe birth defects. This tragedy highlighted the need for strict regulatory oversight and rigorous safety standards in the pharmaceutical industry.
1962- Kefauver-Harris Amendments (USA)
In response to the thalidomide tragedy, the U.S. enacted the Kefauver-Harris Amendments to the Food, Drug, and Cosmetic Act. These amendments established crucial requirements, including:
Mandatory proof of both safety and efficacy is required before a product can be marketed.
Rigorous regulation of clinical trials.
The groundwork for GMP (Good Manufacturing Practice) requirements in manufacturing.
Late 1960s- The Birth of GMP
The WHO published the first draft of GMP within its Technical Report Series (TRS No. 37), introducing the first draft of Good Manufacturing Practices, a pivotal move towards global drug quality and international harmonization of requirements.
1970s- 2000s- Global Expansion of GMP
1970s- Adoption by National Authorities
The U.S. FDA adopted GMP regulations (later called cGMP -current GMP).
The European Economic Community (EEC) issued directives requiring pharmaceutical manufacturers in Europe to follow GMP.
WHO began assisting member states in adopting GMP into their national laws.
WHO published “Good Manufacturing Practices for Pharmaceutical Products: Main Principles” in TRS 908, Annex 4, which became a global reference point for national regulators.
2009- Strengthening the WHO GMP
WHO TRS 986 (2009), Annex 2. This unified document set the standard for international GMP, highlighting:
Quality management systems
Documentation control
Process validation
Risk-based approaches
2017- Sterile Products Guidance
WHO TRS 1044 (2017), Annex 2: Given the intricate nature of sterile manufacturing (think injections and ophthalmic products), the WHO has revised its GMP guidance for sterile pharmaceuticals, bringing it into close alignment with the EU GMP Annex 1.
GMP in India- Evolution of Schedule M

India’s regulatory framework was established under the Drugs and Cosmetics Act 1940 and Rules, 1945, with the minimal initial manufacturing standards.
1988- Schedule M GMP Introduction
Mandating the basic requirements in terms of premises, equipment, and documentation for the very first time, India introduced GMP under Schedule M.
A significant amendment, notified on December 11, 2001, updated Schedule M to better align with WHO Good Manufacturing Practices (GMP), thereby making GMP a mandatory requirement for all pharmaceutical manufacturing facilities in India.
India made a monumental move on December 28th, 2023, with the G.S.R. 912(E) notification. This landmark update introduces a revamped Schedule M, ushering in:
Pharmaceutical Quality System (PQS), perfectly aligned with ICH Q10 standards.
Risk Management Principles, mirroring the robust guidelines of ICH Q9.
Present condition
GMP is a global standard, adopted by over 100 countries, either directly via WHO guidelines or indirectly by aligning with regulations from the U.S. FDA, EMA, or PIC/S (Pharmaceutical Inspection Convention and Pharmaceutical Inspection Co-operation Scheme). It forms the essential basis for regulatory compliance in the pharmaceutical industry, ensuring that patients consistently receive medicines that are safe, effective, and of high quality.
What is WHO GMP
WHO GMPs are global standards for pharmaceutical quality, safety, and consistency. It's a system focused on preventing risks during production, rather than solely relying on end-product testing, to ensure products are consistently produced and controlled according to quality standards.

Why WHO GMP required
The World Health Organization (WHO) introduced Good Manufacturing Practices (GMP) in 1968 through its Technical Report Series (TRS No. 37). The need arose from:
Public Health Tragedies
Tragedies like the 1937 Sulfanilamide disaster in the USA and the 1961 Thalidomide disaster in Europe demonstrated that unsafe medications can lead to widespread deaths and lasting health problems.
These events underscored that ensuring quality requires preventing errors, contamination, and unsafe practices during manufacturing, rather than relying solely on testing finished products.
Lack of Global Harmonization
Previously, each country, if it had any regulations, adhered to different standards. Developing nations often lack manufacturing regulations, posing risks to patients and hindering international trade.
The WHO established GMP to set a global standard for medicine quality, particularly for member states without well-developed regulatory systems.
Global Public Health Needs
WHO GMP was created to guarantee that safe, effective, and high-quality medicines are available globally, especially in low- and middle-income nations.
It serves as the foundation for national GMP regulations, such as India's Schedule M, EU GMP, and PIC/S standards.
