Stability Study, Scope:
[][]This procedure is applicable for
[][]Development of New Product.
[][]Reformulation of existing products.
[][]Routine study of commercial batches.
[][]Change of specification of raw and primary packing material.
[][]Process change.
[][]Change of batch size.
[][]Rework reprocess and investigational batches.
of all pharmaceutical products at XX Pharmaceuticals limited.
Definitions / Abbreviation:
Stability Studies:
[][]Long-term and accelerated (and intermediate) studies undertaken on Development and/or production batches according to a prescribed stability protocol to establish the shelf-life of an finished pharmaceuticals product.
Accelerated Testing:
[][]Studies designed to increase the rate of chemical degradation or physical change of an active substance or pharmaceutical product by using exaggerated storage conditions as part of the formal stability studies.
Long Term Testing:
[][]Stability studies under the recommended storage condition for the re-test period or shelf life proposed (or approved) for labeling.
Development-scale Batch:
[][]A batch of an FPP manufactured by a procedure fully representative of and simulating that to be applied to a full production-scale batch. For example, for solid oral dosage forms, a Development scale is generally, at a minimum, one-tenth that of a full production scale or 100 000 tablets or capsules, whichever is the larger; unless otherwise adequately justified.
Specification:
[][]A list of tests, references to analytical procedures, and appropriate acceptance criteria, which are numerical limits, ranges or other criteria for the tests described. It establishes the set of criteria to which an FPP should conform to be considered acceptable for its intended use.
Release Specification:
[][]The combination of physical, chemical, biological, and microbiological tests and acceptance criteria that determine the suitability of an FPP at the time of its release.
Shelf-life Specification:
[][]The combination of physical, chemical, biological, and microbiological tests and acceptance criteria that an FPP should meet throughout its shelf life.
Shelf-life:
[][]The period of time during which an FPP, if stored correctly, is expected to comply with the specification as determined by stability studies on a number of batches of the API or FPP. The shelf-life is used to establish the expiry date of each batch.
Expiry Date:
[][]The date given on the individual container (usually on the label) of a product up to and including which the API and FPP are expected to remain within specifications, if stored correctly. It is established for each batch by adding the shelf-life to the date of manufacture.
Bracketing:
[][]The design of a stability schedule such that only samples at the extremes of certain design factors, e.g. strength and package size, 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.
Matrixing:
[][]The design of a stability schedule such that a selected subset of the total number of possible samples for all factor combinations is tested at a specified time point. At a subsequent time point, another subset of samples for all factor combinations is tested. The design assumes that the stability of each subset of samples tested represents the stability of all samples at a given time point.
Container Closure System:
[][]The sum of packaging components that together contains and protects the dosage form. This includes primary packaging components and secondary packaging components, if intended to provide additional protection to the pharmaceutical product.

[][]Failure to meet the acceptance criteria for appearance, physical attributes and functionality test
[][]Also, as appropriate for the dosage form:
[][]Failure to meet the acceptance criterion for pH; or
[][]Failure to meet the acceptance criteria for dissolution for 12 dosage units.
Data evaluation procedure
[][]In general, a provisional shelf-life of 24 months will be established provided the following conditions are satisfied:
[][]The API is known to be stable (not easily degradable).
[][]Stability studies, of API, have been performed and no significant changes have been observed.
[][]Supporting data indicate that similar formulations have been assigned a shelf-life of 24 months or more.
[][]Long-term studies to be continued until the proposed shelf-life has been covered, and the results obtained will be submitted to the national medicines regulatory authority.
[][]Alternatively, after the availability of sufficient long term data, shelf life will be declared following any of the following process:
[][]If the Accelerated stability data shows no significant change, the long term data shows little or no variability and the accelerated data also shows little or no variability then shelf life will be declared as double the time of available long term data but, it should not exceed long term data availability time + 12 month (Y = 2X, but should not exceed Y = X + 12 Month, Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 2 x 12 = 24 Month. If 24 month long term data will be available, shelf life will be 24 + 12 = 36 month but not 24 x 2 = 48 month.
[][]If accelerated data shows significant change, but long term data shows no significant change and shows little or no variability, a statistical analysis will be performed with graphical representation with 5% upper and lower acceptance criteria. Available data will be then extrapolated to figure out time to attain the lower acceptance criteria.
[][]If backed by the above graphical representation shelf life will be declared as 1.5 time of available long term data but, it should not exceed long term data availability time + 6 month (Y = 1.5X, but should not exceed Y = X + 6 Month Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 1.5 x 12 = 18 Month. If 24 month long term data will be available, shelf life will be 24 + 6 = 30 month but not 24 x 1.5 = 36 month.
[][]If the Accelerated stability data shows no significant change, the long term data shows variability and the accelerated data also shows little or no variability a statistical analysis will be performed with graphical representation with 5% upper and lower acceptance criteria. Available data will be then extrapolated to figure out time to attain the lower acceptance criteria.
[][]If backed by the above graphical representation, shelf life will be declared as double the time of available long term data but, it should not exceed long term data availability time + 12 month (Y = 2X, but should not exceed Y = X + 12 Month Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 2 x 12 = 24 Month. If 24 month long term data will be available, shelf life will be 24 + 12 = 36 month but not 24 x 2 = 48 month.
[][]If sufficient data are not available to perform the statistical analysis shelf life will be declared as 1.5 time of available long term data but, it should not exceed long term data availability time + 6 month (Y = 1.5X, but should not exceed Y = X + 6 Month Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 1.5 x 12 = 18 Month. If 24 month long term data will be available, shelf life will be 24 + 6 = 30 month but not 24 x 1.5 = 36 month.
[][]If the Accelerated stability data shows no significant change, the long term data shows variability and the accelerated data also shows variability a statistical analysis will be performed with graphical representation with 5% upper and lower acceptance criteria. Available data will be then extrapolated to figure out time to attain the lower acceptance criteria.
[][]If backed by the above graphical representation, shelf life will be declared as double the time of available long term data but, it should not exceed long term data availability time + 12 month (Y = 2X, but should not exceed Y = X + 12 Month Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 2 x 12 = 24 Month. If 24 month long term data will be available, shelf life will be 24 + 12 = 36 month but not 24 x 2 = 48 month.
[][]If sufficient data are not available to perform the statistical analysis shelf life will be declared as 1.5 time of available long term data but, it should not exceed long term data availability time + 6 month (Y = 1.5X, but should not exceed Y = X + 6 Month Where Y = proposed shelf life, and X = period covered by long term data). Such as if a product meets all the above criteria with 12 month long term data, then shelf life will be 1.5 x 12 = 18 Month. If 24 month long term data will be available, shelf life will be 24 + 6 = 30 month but not 24 x 1.5 = 36 month.
