Good manufacturing practice
Good manufacturing practices (GMP) are the practices required in order to conform to the guidelines recommended by agencies that control authorization and licensing for manufacture and sale of food, drug products, and active pharmaceutical products. These guidelines provide minimum requirements that a pharmaceutical or a food product manufacturer must meet to assure that the products are of high quality and do not pose any risk to the consumer or public. Good manufacturing practices, along with good agricultural practices, good laboratory practices and good clinical practices, are overseen by regulatory agencies in the United States, Canada, Europe, China, and other countries.
Good manufacturing practice guidelines provide guidance for manufacturing, testing, and quality assurance in order to ensure that a food or drug product is safe for human consumption. Many countries have legislated that food,and pharmaceutical and medical device manufacturers follow GMP procedures and create their own GMP guidelines that correspond with their legislation.
All guidelines follow a few basic principles:
-Manufacturing facilities must maintain a clean and hygienic manufacturing area.
-Controlled environmental conditions in order to prevent cross contamination of food or drug product from adulterants that may render the product unsafe for human consumption.
-Manufacturing processes are clearly defined and controlled. All critical processes are validated to ensure consistency and compliance with specifications.
-Manufacturing processes are controlled, and any changes to the process are evaluated. Changes that have an impact on the quality of the drug are validated as necessary.
-Instructions and procedures are written in clear and unambiguous language. (Good Documentation Practices)
-Operators are trained to carry out and document procedures.
-Cross contamination with unlabelled major allergens is prevented.
-Records are made, manually or by instruments, during manufacture that demonstrate that all the steps required by the defined procedures and instructions were in fact taken and that the quantity and quality of the food or drug was as expected. Deviations are investigated and documented.
-Records of manufacture (including distribution) that enable the complete history of a batch to be traced are retained in a comprehensible and accessible form.
-The distribution of the food or drugs minimizes any risk to their quality.
-A system is available for recalling any batch from sale or supply.
-Complaints about marketed products are examined, the causes of quality defects are investigated, and appropriate measures are taken with respect to the defective products and to prevent recurrence.
Practices are recommended with the goal of safeguarding the health of consumers and patients as well as producing good quality food, medicine, medical devices, or active pharmaceutical products. In the United States, a food or drug may be deemed "adulterated" if it has passed all of the specifications tests, but is found to be manufactured in a facility or condition which violates or does not comply with current good manufacturing guideline. Therefore, complying with GMP is mandatory in all pharmaceutical manufacturing, and most food processing. GMP guidelines are not prescriptive instructions on how to manufacture products. They are a series of general principles that must be observed during manufacturing. When a company is setting up its quality program and manufacturing process, there may be many ways it can fulfil GMP requirements. It is the company's responsibility to determine the most effective and efficient quality process. The quality is built into the product and GMP is the most essential part of ensuring this product quality.
