Final answer:
The Beyond-Use Date (BUD) for nonaqueous and solid formulations is the date indicates when a compounded preparation is no longer safe to use. For nonaqueous liquid and solid formulations, the BUD is not later than 6 months or the soonest expiration date of any active pharmaceutical ingredient, whichever comes first.
Step-by-step explanation:
Beyond-Use Dates (BUD) for Nonaqueous & Solid Formulations
A Beyond-Use Date (BUD) is the date after which a compounded preparation should not be used and is to be discarded. This date is typically determined by the pharmacist and is based on factors such as the nature of the drug, the type of dosage form, and the container in which it is dispensed. For nonaqueous liquid and solid formulations, the BUD is generally not later than the time remaining until the earliest expiration date of any API or 6 months, whichever is earlier, after being compounded. Nonaqueous formulations are those that do not contain water, such as an ointment or gel, whereas solid formulations refer to forms such as tablets or capsules.
