Having saved US consumers over $1.5 trillion in the past decade, generic drugs are one of the most cost-effective interventions in our entire health care system. Using generic drugs instead of brand-name drugs, when a generic is available, has been shown to increase medication adherence and improve health outcomes for chronic conditions.
Importantly, generic drugs offer these advantages without sacrificing quality; the Food and Drug Administration’s bioequivalency standards are met and often exceeded by generic-name manufacturers, and no randomized controlled trials—the gold standard of medical evidence—have identified clinically significant variations in outcomes between brand-name and FDA-approved interchangeable generic drugs.
However, to perform the tests the Food and Drug Administration (FDA) requires before approving a generic drug, manufacturers need access to one vital component: the brand-name product. Samples of the brand-name version of a drug can be used as a comparator to demonstrate the similarity of the molecular structure, or even the clinical outcomes from the generic product. Physico-chemical details about the brand-name drug, such as its molecular structure, stability, and cross-reactions, can be even more helpful in ensuring that the generic version adheres to the highest quality standards.
