What is the central focus of the Purple Book?

The central focus of the Purple Book is bioequivalence evaluations. This important resource is designed to provide guidance on the evaluation of biological products, especially regarding biosimilars. It outlines the criteria that must be met in order to establish that a biosimilar is comparable to its reference product in terms of safety, purity, and potency.

Understanding bioequivalence is crucial because it ensures that alternative products can be substituted for their reference counterparts without compromising the treatment quality and outcomes for patients. This resource plays a pivotal role in fostering confidence among healthcare providers and patients in the safe use of these products, which is critical for effective health care delivery.

In contrast, vaccine guidelines are covered in other resources, while heavy metal properties and animal health guidelines fall outside the scope of the Purple Book's purpose and content.
