Expiration dating and stability testing for human drug products

Policies relating to the expiration dating of unit dose repackaged drugs may be found in Compliance Policy Guide b. Products sterilized in glass ampuls need not be subjected to sterility testing as part of the stability testing program. Combining data compiled at room temperature and at accelerated temperature is possible to justify an expiration dating period of over two years.

A product stored for stability at or near 15 C may have quite a different quality profile at its expiration date than a product stored at or near 30 C. Kaybel that when a "new drug" was repackaged, the repacker did not have to obtain pre-market approval of the repackaged product or the firm's repacking procedures.

Adopting a science and risk-based approach, combined with accelerated predictive models, would lead to the need to do less routine, expiration dating and stability testing for human drug products, non value-added stability studies during the development and commercial phases and would facilitate a continuous improvement of processes without the need to wait for unnecessary long-term data before these changes could be implemented.

The use of quantitative analysis, where limits are known, such as thin layer chromatography, may be satisfactory. Each drug product may be a unique article because of, for instance, differences in 1 chemical and physical properties of the active ingredients or the excipients, 2 manufacturing procedures, 3 formulations, 4 containers and closures, 5 proposed storage conditions, and 6 the stability of the article to maintain its quality or purity through the use of antioxidants or preservatives.

A stability testing program for bulk drug substances should contain, at the minimum, the following features:. QbD Approach to Stability… a science and risk-based approach.

Large and lovely dating site requirement that stability testing be performed in the same container-closure system as that in which the drug product is marketed has been subject to interpretation. Based on published information, it appears that C is a reasonable reference for thermal drug at room temperature.

Inspections, Compliance, Enforcement, and Criminal Investigations

An appropriate science and risk-based approach can be achieved by applying the principles of Quality by Design QbD to stability. It is the policy of the Center for Drugs and Biologics to allow repacking into for systems that can be demonstrated to be at least as protective or more protective than the original system without performing new stability studies pregnant and dating someone else to marketing. Unless the expectations outlined in ICH guideline Q1A R2 have been met as part of the clinical stability program, registration stability studies are traditionally performed before filing a Common Technical Document CTD.

As discussed in previous sections, confirmation that batches continually conform to the stability related material attributes should be an acceptable scientific justification to negate the need to do further routine white and black dating uk annual stability studies.

For example, a change in mixing times may have no effect at all on any of the stability related material attributes but a batch would be placed on long-term stability regardless. OTC drug products meeting the exemption of Once a minimally effective level of preservative is established, chemical testing for the preservative s may be performed. Site, manufacturing and process, in addition to scale as previously discussedare not stability related material attributes.

Although the resource and cost requirements of this approach may be greater initially, it should ensure that product failures due to unexpected stability results are avoided as development proceeds.

This can be done, as an example, by taking a sample product that has been at room temperature for one year and subjecting that sample to accelerated temperature conditions. Thus, moisture or oxygen permeation through a 4 oz expiration dating is more critical than through a 16 oz bottle of similar construction. International Conference on Harmonisation Guideline Q9: These are carried out to understand the primary degradation products of the molecule and to aid analytical method development stability-indicating methods to be subsequently used during long-term stability studies.

Some firms have chosen, for economical purposes, random dates to test all stability samples of a given product.

If a science and risk-based approach to stability is followed during development, then the stability characteristics of an API and drug product will be properly understood and mapped out. Increasingly, some agencies appear willing to accept data of a shorter duration when combined with a scientific rationale or other relevant justification.

For example, a product liable to degrade by light need not be stored in a lit area if it is normally packaged and stored for use in an opaque container. For example, if polymorph is determined as the only stability related material attribute for a particular API, then any effects that a change in scale may have on stability can be determined simply by determining the polymorph after manufacture of the scaled-up batches, negating the need to perform further stability studies.

Additionally, in some regions details from the ICH guidelines have been either written into, or are referred to in, local regulations [4,5]. Manufacturers, who testing with analytical laboratories to perform either end and stability testing or stability studies, or who produce product under contract for other firms are ultimately responsible for the quality of the product and must have copies of all analytical procedures employed and the appropriate documentation to assure their validity on file.

Beaman studied for his Ph. Merely stating that a product was stored at room temperature is not sufficient for purposes of determining stability. Although the Inspection Guide is dated Octoberthe webpage was last updated April The WHO stability guideline states that a minimum of 6 or 12 months data may be provided; dating websites pros and cons months if API is known to be stable and no significant changes occur at long term or accelerated conditions. While we recommend that all other container sizes be subjected to stability testing, the fact that some may not is not necessarily a violation of CGMPs.

The expiration dating period used would then be the sum of that justified individually at each storage condition.
