What is the Origin of Beyond-Use Date (BUD)?

This term is a fundamental component of pharmaceutical compounding standards, primarily established by regulatory bodies like the United States Pharmacopeia (USP) in its chapters dedicated to compounded preparations. The concept was introduced to provide clear, evidence-based standards for the shelf life of medications prepared extemporaneously that lack extensive manufacturer stability testing.

What is the Mechanism of Beyond-Use Date (BUD)?

The assignment of the BUD is a professional judgment process involving the assessment of several key factors, including the inherent chemical stability of the active pharmaceutical ingredients (APIs), the physical properties of the formulation vehicle, and the designated storage conditions. Potential degradation, microbial growth, or physical separation of the compounded hormonal product dictates the established date. This mechanism ensures that the patient receives a product that retains its prescribed potency and quality throughout the entire course of treatment.

Beyond-Use Date (BUD)

Meaning

The Beyond-Use Date (BUD) is the assigned date after which a compounded pharmaceutical preparation, such as a personalized hormonal cream or injection, should no longer be used, signifying the period during which it is expected to remain stable. This date is determined by the compounding pharmacist based on specific stability data and regulatory guidelines, unlike the manufacturer’s expiration date. The BUD is a crucial measure for maintaining patient safety and ensuring the therapeutic efficacy of customized hormonal medicine.
