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 light, 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 that 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.
Compounding Pharma Guidance
The FDA has indicated its intention to create a new set of rules that apply specifically to compounding pharmacies. Release Testing involves assuring the drug product meets predetermined specifications for quality by verifying the proper identity and strength of the Active Pharmaceutical Ingredient API , and the overall purity of the drug product. Many compounding firms use a third-party lab to conduct this testing.

Introduction to ICH Guidelines. 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.
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.

Dispensing expired medication is known as a prescription error and is a type of medical malpractice. An expiration date is a guarantee of potency from the manufacturer. If medication is used after this date, the company is not responsible for its potency level or effectiveness. Additionally, pharmacists are not allowed to dispense expired prescription medications.
Over-the-counter medications should not be sold once their expiration date passes. Since , the United States Food and Drug Administration requires both prescription and over-the-counter medications to include expiration dates to let pharmacists and consumers know that the medication is safe to take and will work. If someone takes medication after it expired, it is possible that the medication will not be effective and could even be dangerous.
For a free legal consultation, call More research into expired medication safety is needed to fully understand what could happen when you take outdated medications. The list above highlights only some of the potential problems. While it is unlikely that consuming expired medication will poison you, some formulas are unsafe after a long period of time.
The expiration date is not always an indicator of safety, as some medications are still potent after their expiration date. However, some medications, such as insulin, are less stable. If you take medication after its expiration date and get sick, the manufacturer does not face the same liability as it would if the medication had not expired.
U.S. Food and Drug Administration
Labeling and packaging materials shall be representatively sampled, and examined or tested upon receipt and before use in packaging or labeling of a drug product. Any labeling or packaging materials that do not meet such specifications shall be rejected to prevent their use in operations for which they are unsuitable. Access to the storage area shall be limited to authorized personnel. Such examination shall be performed by one person and independently verified by a second person.

Why stability testing is important : The FDA and other regulatory bodies control for every significant aspect of manufacturing, storage, and distribution, leaving little room for error. In order to achieve market success, new drugs must not only be effective and safe, but also predictable in their stability and storage. The above process ensures that pharmaceutical products are safe and effective, regardless of the location or environment they are distributed to.
Stability testing, however, is far more than a mere recommendation for prudent pharmaceutical companies. Furthermore, due to increasing collaboration between various relevant institutions, geographically specific agencies such as the FDA and EMA have begun to accept reciprocal standards. The ICH outlines types of conditions that should be applied to any drug seeking to gain market approval. This creates an interplay between pharmaceutical companies and the watchdogs overseeing them, as firms initially set stability testing standards which are later accepted or rejected by regulatory entities, all in the name of increased consumer safety and reduced commercial liability.
This is not to say, however, that regulatory entities obligate every pharmaceutical firm to follow the same uniform process in their stability testing. As long as the parameters set out by the ICH are met, companies can do so in whichever way they consider most convenient. How stability testing is performed: The open-ended nature of regulatory demands, in regard to stability testing, means that there is a plethora of ways that firms can potentially investigate their product.
FDA statute By ensuring that regulatory standards are still flexible in their implementation, the FDA intentionally allows for creativity within pharmaceutical firms. In short, firms are handed down a set of mandated standards but unencumbered by a mandated process.
Regulatory Guidelines on Stability Testing and Trending of Requirements
The first guidance listed is a temporary policy for the compounding of certain human drug products for hospitalized patients by outsourcing facilities, and is intended to remain in effect only for the duration of the public health emergency related to COVID declared by the Department of Health and Human Services HHS. It should be noted that the drugs that are the subject of this policy may change during the course of the emergency.
FDA continues to work with manufacturers in the global pharmaceutical supply chain to prevent and mitigate drug shortages and access problems, but additional flexibility is temporarily needed in order to ensure that treatment options are available when hospitals are unable to obtain FDA-approved drugs used for hospitalized patients with COVID The requirements for establishing Beyond Use Dating and expiration dating are detailed in the attachments of this document.
Tests required for establishing BUD and expiration dating beyond the default times are listed in Appendix C along with allowances for bracketing of data from studies of compounded preparations of differing strengths using the same container closure systems.

New FDA inspection program released for “streamlined approach” for combination product cGMP
Publishing of 21 CFR Part – Current Good Manufacturing Practice for Finished Pharmaceuticals established requirements concerning the expiration date on a drug product and stability testing to assure the appropriateness of that date. 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.
Because of the uniqueness of each drug product, it is virtually impossible to provide one set of rules that can apply to all situations. The CGMPs were purposely written broadly to allow for such unique differences. The absence of an expiration date on any drug product packaged after September 29, , except for those drugs specifically exempt by
Two quality control topics addressed in the Guidance are Release Testing and Stability/Expiration Dating. Release Testing involves assuring the drug product.
September , Volume Number 9 , page 19 – 19 [Free]. Join NursingCenter to get uninterrupted access to this Article. A patient at the primary care clinic where I work took two ibuprofen tablets and soon noticed that the expiration date had passed nearly a year ago. She asked if the medication is still effective. What should I tell her?
The date will often be found next to the letters “EXP” on the printed label or stamped in plastic. This tells the consumer that the medication is safe to use and meets manufacturer potency standards until the last day of the printed month and year. The drug may still be just as effective after this date, but the manufacturer guarantees its quality only until the stated date.
This date is unique to each drug product and manufacturer due to differences in chemical and physical properties of the active and inactive ingredients, manufacturing procedures, formulations, containers and closures, suggested storage conditions, and other factors. Once a medication is beyond its expiration date, changes in potency, pH, water content, and appearance may render it ineffective.
However, this isn’t always the case.

comments on the Food and Drug Administration’s (“FDA” or program should monitor the combination product over its shelf life and determine that it remains, and Dating and Stability Testing for Human Drug Products,”.
Full details of stability testing conducted on the product together with associated validation must be included in the submission. At the time of submission, the data package should include sufficient stability data to justify a shelf life of at least 12 months. On this page: 9. The objective of a stability study is to determine the time during which a pharmaceutical product meets appropriate standards when stored under defined conditions.
The product must be shown to remain, or be likely to remain, within its expiry specifications throughout the proposed shelf life when stored under the proposed storage conditions. The requirement to remain within the expiry specifications applies to all batches, including those which may be released at the low end of the release limits. Therefore, the difference between release and expiry specifications must take into account the results of stability testing.
The formulation and the manufacturing process used to manufacture the formulation used in the stability studies should be the same as that proposed for registration. Stability data on related formulations may be submitted as supporting evidence provided the differences between the formulation employed in the stability trial, and that proposed for registration are clearly stated and the relevance justified.
A shelf-life will not normally be allocated for the purposes of registration if there are no data on the formulation to be registered. The stability of the finished product should be assessed in the container closure system proposed for registration. Stability data in other types of container are of limited value, unless comparative studies are provided that clearly demonstrate the equivalence or superiority of the container closure system intended for registration over the system used in the stability trials.
The critical summary should include all of the following for each of the submitted studies :. Where a sponsor applies to extend the shelf life of a registered product, the critical summary should address the above points and also state whether stability studies for the product have previously been evaluated by the TGA.
