Why are BUD studies important?
Extended BUDs

What is the advantage of having extended BUD?

The BUD is the date or time, after which a compounded preparation can no longer be used, administered or stored, and is determined from the date the preparation is compounded.

USP <795>, NAPRA and APF have set forth guidelines for establishing beyond-use-dating of compounded preparations
Compounders should take into consideration the properties of the API(s), any excipients, the type of dosage form as well as container closure and storage conditions
Establishing the BUD of a compounded preparation should be based on concrete scientific data
The correct way to obtain an evidence-based BUD is by conducting a stability-indicating study
In the absence of supporting stability data, pharmacists refer to USP, NAPRA or APF guidelines

BUD stability studies help to ensure the integrity of the compounded preparation is maintained using validated, stability-indicating methods
They diminish potential risks that can affect patients, such as degradation of the active which can affect potency as well as safety due the formation of by-products over time, which can potentially be dangerous to the user
A stability-indicating study determines whether a preparation is able to maintain its strength and properties throughout its period of preparation, storage and use and to protect itself from degradation over time
These studies also allow compounders to extend the dating of compounded preparations beyond the default guidelines
In compliance with PCAB requirements for extending BUDs

Benefit the patient by:
- Increasing the accessibility of medically necessary treatments (ex. patients living far from a pharmacy or on vacation)
- Reducing prescription renewal frequency and in turn reducing costs
- Offering more peace of mind in receiving a compounded preparation
Benefit the pharmacy by:
- Improving pharmacy workflow
- Reducing costs by reducing labor (due to improved workflow), compounding larger batches and saving on shipping
- Providing the opportunity to prepare stock solutions

BUDs are much larger than they seem:

Stability-Indicating Studies are the gold standard for BUDs.
Expand the questions to see the bigger picture.

What is a stability-indicating study?

A stability-indicating study consists of a validated, quantitative, analytical procedure used to detect how the stability of a drug changes over time.
Stability-indicating assays can use techniques such as HPLC, MS, LC-MS/MS
A stability study includes:
- Method development
- Method validation
- Forced degradation study

Forced-degradation

Exposing the compound to extreme conditions (heat/humidity/uv radiation/acids/bases)
Separating the drug from degradant
Determining quality and durability of a compounded preparation

How do you determine you have a good stability-indicating study?

Stability-indicating assays
Validated methods
Statistical analysis
Independent & objective results
Published and peer-reviewed (bonus!)
Bracketed (bonus!)

What is a bracketed study?

The study of two concentrations of a specific API or formulation in the same base, container closure system and under the same storage conditions
The only variable is the difference in concentration of the drug – all other factors remain consistent throughout both studies
Any concentration within the bracket can receive the extended BUD if all parameters are kept the same (eg., concentration of levigating agent, base, container closure, storage condition, etc.)

In keeping up with industry trends and the ever-changing regulatory landscape, we have reformulated:

"We are committed to staying ahead of international standards when providing products for our clients. We are also heavily invested in providing our pharmacists with a databank of studies and formulas to convert these products into the best quality care for their patients."
- Andrew Rowe, Senior Vice President at Medisca.
