Extended Stability Studies for BUD Justification
Extended stability studies supporting beyond-use date justification.
Scientific Evidence for Defensible BUD Decisions.
Extended stability studies provide the scientific evidence needed to evaluate the quality, potency, purity and performance of compounded preparations throughout their proposed storage period.
Our stability programs are designed to generate scientifically sound data that can support Beyond-Use Date justification while considering formulation, packaging, storage conditions and applicable regulatory expectations.
- Support BUD Justification
- Evaluate Product Stability
- Generate Defensible Stability Data
Comprehensive Stability Evaluation
Comprehensive stability evaluation designed to support scientifically justified BUD decisions and applicable compounding quality requirements.
Scientifically Designed Stability Programs
Each stability program is structured around the intended formulation, container-closure system, storage condition and proposed BUD to generate meaningful and interpretable stability data.
Study Protocol Development
Development of appropriate stability protocols defining test parameters, sampling intervals, storage conditions and acceptance criteria.
Storage Condition Selection
Evaluation under appropriate long-term, accelerated or other relevant storage conditions.
Sampling Schedule
Planned sampling intervals designed to characterise product performance throughout the proposed stability period.
Stability Acceptance Criteria
Scientifically appropriate criteria established for evaluating changes in critical quality attributes.
Chemical Stability & Potency Evaluation
Chemical stability testing helps determine whether the active pharmaceutical ingredient and other relevant components remain within established quality requirements throughout the proposed BUD period.
Assay & Potency
Quantitative assessment of active ingredient concentration over the stability period.
Degradation Products
Monitoring of relevant degradation products and chemical changes during storage.
pH Evaluation
Monitoring of pH changes that may indicate formulation instability or degradation.
Related Substances
Evaluation of relevant impurities and related substances using appropriate analytical methods.
Comprehensive Product Stability Assessment
Stability evaluation extends beyond chemical potency. Physical characteristics and, where applicable, microbiological quality are assessed to provide a broader understanding of product performance during storage.
Appearance & Physical Characteristics
Monitoring of colour, clarity, precipitation, phase separation and other visible changes.
Particulate & Dosage Form Evaluation
Assessment of relevant physical attributes according to the dosage form and study design.
Microbiological Quality
Applicable microbiological testing to evaluate product quality during the proposed storage period.
Container-Closure Assessment
Consideration of packaging and container-closure systems that may influence product stability.
Stability Data to Support Beyond-Use Date Decisions
Stability results can be evaluated against predefined acceptance criteria to establish the scientific basis for a proposed Beyond-Use Date, subject to the applicable standards, formulation characteristics and study design.
Trend Evaluation
Assessment of analytical results over time to identify meaningful changes in critical quality attributes.
Specification Assessment
Comparison of observed results with predefined acceptance criteria and applicable requirements.
BUD Data Interpretation
Scientific interpretation of stability findings in relation to the proposed storage period and formulation.
Supporting Documentation
Organised stability data and study outputs to support quality documentation and BUD justification.
Supporting Applicable Compounding Standards & Expectations
Stability programs can be structured to support documentation and scientific evaluation relevant to USP <795>, USP <797>, USP <800> and applicable FDA expectations, as appropriate to the product and intended use.
