Introduction to ICH Guidelines

Each strength of a drug product, and each primary package and closure system in which it is distributed must be supported by stability testing. If you are contracting this work to a third party laboratory be sure that they can provide guidance to help navigate the regulatory and compendial guidelines, and you perform a quality system audit of their facility. A stability study is a program of testing that is designed to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and which enables recommended storage conditions, retest periods, and shelf lives to be established. Stability testing is required to be conducted for OTC drug products under the recommended conditions of storage appearing on the label, and at any other condition the drug product might be exposed to during manufacturing, storage and shipping activities. As a result, there are a number of stability conditions which are commonly utilized in determining the stability of a drug product in its marketed package s. Examples of the most common stability conditions are as follows:. A stability study conducted under controlled temperature and humidity approximating conditions of long-term storage.

This is not required for drug products packaged in completely opaque container systems. A stability study that is conducted under long-term conditions to assess the stability of a product batch in its bulk container.

This applies to situations where a drug product may be stored in a bulk container for a period of time prior to its placement into end-user packaging.

That being said, FDA understands that drug owners would face undue hardship if they were required to wait the full two years it would take to generate RT stability data before launching a new OTC drug product with a 2-year expiration date. As a result, FDA allows for the extrapolation of accelerated stability data for determining expiry dating for initial launch, however FDA also requires that the same batch that was used for the accelerated study must also undergo concurrent RT stability testing.

Accelerated stability studies alone cannot be used to support the expiration dating of OTC drug products. The results of accelerated studies must be confirmed through the conducting of RT stability studies.

As stated in the previous section, the results of accelerated stability studies may be used to approximate the shelf life of a new OTC drug product for launch.

Historically, FDA has permitted three 3 months of acceptable accelerated stability test results to support a 2-year expiration date for product launch.

What Types of Stability Studies are Commonly Conducted?

However, in recent years, FDA has tightened up its stability requirements for prescription Rx drugs, now requiring six 6 months of accelerated stability and one 1 year of RT stability data at the time of submission, and for it, granting only an month sometimes less expiration date. Since OTC drug policy eventually tends to follow along the lines of Rx policy, it is prudent that for the launch of new OTC drug products, that six 6 months of accelerated stability testing now be conducted to support a 2-year expiry date for launch.

It should also be noted that anything less than three 3 months of acceptable accelerated stability data cannot be routinely used to support any expiry date.

Extending the accelerated storage time or storing under harsher conditions will not routinely support a 3-year expiration date. All Rights Reserved. Interested in participating in our trials?

Neumann October 26, What is a Stability Study and What is its Purpose? Examples of the most common stability conditions are as follows: Real Time or Room Temperature RT Stability Study A stability study conducted under controlled temperature and humidity approximating conditions of long-term storage.

Accelerated Stability Study A stability study conducted under exaggerated conditions, in an attempt to accelerate the aging process, i. Intermediate Stability Study A stability study that is conducted under conditions that are intermediate between long-term and accelerated storage conditions.

Photostability Study A study that is conducted to determine the effect that either whole or ultraviolet light has upon the stability of a product.

Bulk Hold Stability Study A stability study that is conducted under long-term conditions to assess the stability of a product batch in its bulk container. As long as there is at least one test performed annually, this approach can be quite satisfactory. If a product was stored under controlled conditions, those actual conditions temperature and humidity should be recorded.

Merely stating that a product was stored at room temperature is not sufficient for purposes of determining stability. 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.

Based on published information, it appears that C is a reasonable reference for thermal exposure at room temperature. Stability studies should be conducted on product stored under normal storage conditions or, preferably, under exaggerated conditions. Products liable to degradation by light or moisture should be stored either in a lighted area or under conditions of high humidity unless it can be demonstrated that the packaging will prevent deterioration by that condition of interest.

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. While Section Testing procedures must include a stability indicating test which will distinguish the active ingredient from any degradation products and be able to make a reliable estimate of the quantity of any degradate. The stability indicating test does not have to be the assay method used to determine product strength.

Manufacturers, who contract with analytical laboratories to perform either end product 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.

Likewise, repackers who rely on stability studies performed by the manufacturer must have copies of all analytical data necessary to support the expiration dating period. Although specific methods are critical to determine product stability, they do not have to employ any specific technique.

The use of quantitative analysis, where limits are known, such as thin layer chromatography, may be satisfactory.

While many USP tests are specific for the drug or its degradates and may be used for stability testing, some USP monographs do not incorporate stability indicating tests. Additionally, it may be unreasonable to expect a manufacturer to develop specific methodology for each component of some multi-component drugs containing ingredients of botanical origin such as benzoin, Peruvian balsam or tolu balsam.

Aug 01,  · However, the FDA Inspection Guide on "Expiration Dating and Stability Testing for Human Drug Products" states under Stability Testing, B "it is imperative that stability studies are not limited only to initial production batches but a portion of annual production batches be the subject of an ongoing stability program".

Although stability studies were performed on the dosage unit in the original manufacturer's container, the event of placing the dosage unit into a different storage unit may and often does affect the product's shelf life. It is the policy of the Center for Drugs and Biologics to allow repacking into container-closure systems that can be demonstrated to be at least as protective or more protective than the original system without performing new stability studies prior to marketing.

Satisfactory comparison of container-closure systems may be done by several methods, i. Stress testing refers to testing the product after storage under exaggerated conditions.

This will usually involve high temperature and high humidity. It is also current policy to allow firms to repackage solid dosage units from plastic containers into glass containers because glass has been shown to be a superior moisture and gas barrier.

When the same product is marketed in more than one size, e. This indicates that the smallest marketed container is the most critical in terms of the container properties contributing to product degradation. Thus, moisture or oxygen permeation through a 4 oz bottle is more critical than through a 16 oz bottle of similar construction.
