10. Q1A:-STABILITY TESTING OF NEW
API$FPP
Stress testing
Selection of batches
Container and closure systems
Storage conditions
11. Stress testing of API in solution
Storage conditions Testing period*
pH ± 2, room temperature 2 weeks
pH ± 7, room temperature 2 weeks
pH ± 10-12, room temperature 2 weeks
H2O2, 0.1-2% at neutral pH,
room temperature
24 hours
12. Stress testing of FPPs in solid state
Storage conditions Testing period*
40°C, 75 % RH; open storage** 3 months
50-60 °C, ambient RH; open
storage
3 months
** For API1-API2, or API-excipient, or FPP without packing material,
typically a thin layer of material is spread in a Petri dish. Open storage is
recommended, if possible.
13. 3.11.3 Selection of Batches
At the time of submission data from stability studies should be
provided for batches of the same formulation and dosage form in
the container closure system proposed for marketing.
Stability data on three primary batches are to be provided. The
composition, batch size, batch number and manufacturing date of
each of the stability batches should be documented and the
certificate of analysis at batch release should be attached.
Where possible, batches of the FPP should be manufactured by
using different batches of the API.
14. Illustrative data of API stability batches
Batch number
Date of manufacture
Site of manufacture

15. Illustrative data of capsule/tablet stability
batches
Batch number
Date of manufacture
Site of manufacture
Batch size (kg)
Batch size (number of
units)
Primary packing materials
Date of initial analysis
Batch number of the API
16. photo stability testing
A systematic approach to photostability testing
is recommended covering, as appropriate,
studies such as:
i) Tests on the drug substance;
ii) Tests on the exposed drug product outside of
the immediate pack;
and if necessary ;
iii) Tests on the drug product in the immediate
pack;
and if necessary ;
iv) Tests on the drug product in the marketing
Pack
17. Bracketing and matrixing designs
Bracketing:-As defined in the glossary to the parent
guideline, bracketing is the design of a stability
schedule such that only samples on the extremes of
certain design factors (e.g., strength,
container size and/or fill) are tested at all time points as
in a full design. The design assumes that the stability of
any intermediate levels is represented by the stability of
the extremes tested.
18. Matrixing
As defined in the glossary of the parent guideline, matrixing is
the design of a stability schedule such that a selected subset of
the total number of possible samples for all factor combinations
would be tested at a specified time point. At a subsequent time
point, another subset of samples for all factor combinations
would be tested. The design assumes that the stability of each
subset of samples tested represents the stability of all samples at
a given time point. The differences in the samples for the same
drug product should be identified as, for example, covering
different batches, different strengths, different sizes of the same
container closure system etc
19. STABILITY PROTOCOL AND REPORT
1. Batches tested
2. General information
3. Container/closure system
4. Literature and supporting data
5. Stability-indicating analytical methods
6. Testing plan
7. Test parameters
8. Test results
9. Other requirements (post-approval commitments)
10. Conclusions
Result sheets must bear date and responsible person
signature / QA approval
20. Stability results
A storage statement should be proposed for the
labeling (if applicable), which should be based on the
stability evaluation of the API.
A re-test period should be derived from the stability
information, and the approved retest date should be
displayed on the container label.
An API is considered as stable if it is within the
defined/regulatory specifications when stored at
30±2oC and 65±5% RH for 2 years and at 40±2oC
and 75±5%RH for 6 months.
