CHPA supports the U.S. Food and Drug Administration's (FDA) federal regulations ensuring and enforcing product quality for over-the-counter (OTC) medicine and dietary supplement manufacturers.
CHPA member companies continuously monitor the quality and manufacturing processes of their OTC medicines and dietary supplements. Federal regulations issued by FDA provide the regulatory framework for ensuring product quality, starting with the ingredients in these products and continuing through manufacturing, distribution, and the product’s expiration date. Compliance with federal regulations is evaluated by FDA via regular manufacturing facility inspections. Individual states may also have laws and regulations that impact manufacturing and set standards for product quality. A number of organizations also provide guidelines or standards for ensuring product quality. Taking all these laws and regulations into consideration, a manufacturer develops internal standard operating procedures to document their processes and ensure consistently high-quality products are produced for the marketplace.
Due to the wide variety of changes that may be encountered after an OTC monograph drug is marketed, it is impossible to address stability requirements for all changes in this guideline. However, guidance from the examples provided here can be used in the decision-making process.
The Product Quality Research Institute (PQRI) is a non-profit consortium of that generates and shares timely, relevant, and impactful information to advance drug product quality and development. PQRI provides a unique forum to focus critical thinking, conduct research, exchange information, and propose methodology or guidance to pharmaceutical companies, regulators, and standard-setting organizations.
