Proprietary Name Guidances
FDA has issued two guidances on developing proprietary names for human drug products. One guidance covers prescription drug products and the other covers non-prescription products. The documents say they describe best practices to help minimize proprietary name-related medication errors and otherwise avoid the adoption of proprietary names that contribute to violations of the Federal Food, Drug, and Cosmetic Act and its regulations.
They also describe the framework the agency uses to evaluate proposed proprietary names that is available for sponsors to use before a product bearing the proprietary name is marketed. The guidances do not address the designation of established names or proper names.
FDA says that using the best practice recommendations and other assessment tools addressed in the guidance is not mandatory and their application does not dictate specific outcomes. “Assessments of a proprietary name are necessarily fact-specific and, therefore, FDA’s determinations are made on a case-by-case basis, considering the totality of the information,” the agency says.
