"Quality means doing it right when no one is looking." - Henry Ford
While Henry Ford hailed from a motor manufacturing company, this quote on quality applies to other industries as well, including the most regulated industry in the world - the pharmaceutical sector.
And when we talk about pharmaceutical manufacturing, it is indispensable to mention Good Manufacturing Practices (GMP).
In this article, we'll discuss all the basics you need to know about GMP in the Pharmaceutical Industry. So, without further ado, let's get started.
What is GMP?
Good Manufacturing Practices are the backbone of quality assurance in the pharmaceutical industry. They establish the operational conditions and requirements necessary to produce high-quality pharmaceutical products consistently.
The WHO defines GMP as:
"GMP is that part of quality assurance which ensures that products are consistently produced and controlled to the quality standards appropriate to their intended use and as required by the marketing authorization."
Thus, GMP 'standards' are considered as a benchmark for building quality into pharmaceutical products.
GMP was introduced to minimize quality, safety, and efficacy-related risks involved in any pharmaceutical production that cannot be eliminated through testing the final product alone. The spectrum of these risks spans from unexpected contamination of products to incorrect labels on containers, which requires rigorous production and testing environments.
Good Manufacturing Practice isn't limited to the manufacturing area only but covers all aspects of production - from the starting materials, premises, and equipment to the training and personal hygiene of staff. This can be ensured by having detailed, written procedures in place for each process that can affect the quality of the finished product.
Next, there must be systems in place to provide documented proof that correct procedures are consistently followed at each step in the manufacturing process - every time a product is made.
Compliance with GMP is a mandatory aspect of pharmaceutical manufacturing, and adherence to these standards is considered a fundamental aspect of good practice. Regulatory authorities all around the world conduct inspections to verify the compliance of manufacturing companies with GMP standards and guidelines. These inspections ensure that pharmaceutical products are produced and controlled according to quality standards appropriate for their intended use.
Evolution of GMP
The evolution of Good Manufacturing Practices (GMP) within the pharmaceutical industry has been shaped by historical events and regulatory milestones that emphasize the need for adopting standardized manufacturing practices.
In the early 20th century, the lack of regulatory oversight in drug manufacturing led to several public health disasters, notably the Elixir Sulfanilamide incident in 1937, where an improperly tested solvent in a sulfanilamide preparation led to over 100 deaths. This tragedy highlighted the dire need for regulatory oversight and quality control in pharmaceutical manufacturing, leading to the enactment of the Federal Food, Drug, and Cosmetic Act in the United States, which laid the groundwork for modern pharmaceutical regulations.
However, GMP as a standard still wasn't introduced until 1968 when the WHO released their first draft guidance. Soon WHO GMP became a key component of pharmaceutical manufacturing - a few years after the thalidomide tragedy that took place in the late 1950s and early 1960s.
Thalidomide was a drug used to treat nausea in pregnant women between 1950-1960. Unfortunately, thalidomide treatment resulted in severe birth defects in children born around the 1960s. To date, the thalidomide tragedy is considered one of the biggest disasters resulting from poor GMP and regulatory oversight. The thalidomide tragedy catalyzed the global pharmaceutical community towards adopting stringent manufacturing standards. The aftermath of this tragedy saw the introduction of stringent drug approval processes and the foundation of GMP as a set of principles to ensure product safety and efficacy.
