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, 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.

Sep 02, Pharmaceutical Technology Volume 36, Issue 9 The International Consortium on Innovation and Quality in Pharmaceutical Development IQ formed in is an association of over 25 pharmaceutical and biotechnology companies with a mission to advance science-based and scientifically-driven standards and regulations for medicinal products worldwide.
Although more prescriptive guidance is not advocated, the sharing of best practices in this paper is done herein to advance innovation in drug product development by improving cycle times, while maintaining appropriate product quality and ensuring patient safety. A consequence of the absence of clarity surrounding early phase GMP guidance has been varied interpretation and application of existing GMP guidance within different companies and regulatory bodies according to their own culture and risk tolerance.
Internal debates often result in conservative “one-size-fits-all” interpretations that rely on International Conference on Harmonization ICH guidelines that are relevant to commercial product development and do not distinguish differences in practices between early development and later-stage development i.
A key driver of the IQ WG, therefore, has been to collectively define the minimum acceptable practices within industry regarding GMP expectations in early development that allow for added flexibility and that are consistent with existing guidance and statutes 2, 3. The initial scope of these efforts has been limited to small-molecule development, which support First in Human FIH through Phase 2a proof-of-concept clinical studies. A series of whitepapers describing a recommended approach to applying GMPs in each of these areas is being published within this journal.
Guidance for Industry: Stability Testing of New Drug Substances and Products: ICH Topic Q1A(R2)
Next Biopharmaceutical products in storage change as they age, but they are considered to be stable as long as their characteristics remain within the manufacturer’s specifications. The number of days that the product remains stable at the recommended storage conditions is referred to as the shelf life. The experimental protocols commonly used for data collection that serve as the basis for estimation of shelf life are called stability tests. Shelf life is commonly estimated using two types of stability testing:
The expiration date does not exceed (a) 1 year from the date of repackaging or (b) the expiration date on the container of the original manufacturer’s product, whichever is earlier, unless stability data or the original manufacturer’s product.
Are drug expiry dates really a myth? Are drug expiry dates just an industry ploy to keep you buying new bottles of medicine? All of the products are expired. Would you still consider taking any of them? Why or why not? Your answer is probably influenced by a number of factors, including perceptions of risk and benefit. Some feel the expiry date is purely a plot of Big Pharma to sell more drugs.
Others believe that drugs start deteriorating long before the expiry date. Expiry dates are the source of a lot of questions to pharmacists. Because of expiry dates, an enormous quantity of drugs are manufactured and sold or dispensed, but never consumed.
Drug Expiration Dates: How Accurate Are They?
If significant change occurs between 3 and 6 months’ testing at the accelerated storage condition, the proposed re-test period should be based on the real time data available at the long term storage condition. If significant change occurs within the first 3 months’ testing at the accelerated storage condition, a discussion should be provided to address the effect of short term excursions outside the label storage condition, e.
This discussion can be supported, if appropriate, by further testing on a single batch of the drug substance for a period shorter than 3 months but with more frequent testing than usual. It is considered unnecessary to continue to test a drug substance through 6 months when a significant change has occurred within the first 3 months.
(a) To assure that a drug product meets applicable standards of identity, strength, quality, and purity at the time of use, it shall bear an expiration date determined by appropriate stability testing described in .
Compounding pharmacists are expected to prepare safe and efficacious doses of medication under time and economical constraints while protecting pharmacy staff and caregivers from inadvertent exposure to the drug. The pharmacist has the additional responsibility to ensure that the product is stable in the final-administrated form as the time between drug preparation and administration is considerable.
Physical and chemical stability of the CSP can be difficult to maintain over extended storage, especially since the formulation components are diluted within the intravenous i. Recent published reports have suggested the use of extended time, beyond that recommended by the manufacturer, for the storage and administration of CSP. These recommendations were based on inadequate analytical testing of the CSP. Herein, we demonstrate that setting of the beyond-use date should be carefully assessed using the appropriate analytical methods and testing.
Results from our studies clearly indicate that many of the tested IgG1 monoclonal antibodies should not be diluted and stored in i. Results from this study also indicate that i. Previous article in issue.
The article reviews studies pertaining to US manufactured allergen extract stability that contribute to guidance for expiration dating for bulk concentrates, diluted patient testing and treatment vials, and adjustments following elevated temperature excursions. Studies on allergen stability were completed to satisfy the Food and Drug Administration requirements supporting labeled expiration dating for standardized short ragweed, dust mites, cat, grass, and venom extracts and are not published.
Patient vials are commonly given months dating. There is adequate evidence that human serum albumin stabilizes low protein diluted vials. High protease allergens such as molds and insects compromised potency of pollens when mixed.
stability testing programme to vaccines and the mathematical models used in data analysis. Additionally, differences in current practice with regard to the selection of parameters measured and the frequency of testing were identified.
Supportive Stability Data Number and Size of Batches Initial stability testing by accelerated testing may be performed on a batch smaller than the normal production size as long as the batch is produced by similar equipment as would be used for regular production. Generally, the placing of three initial batches into the long term stability program is considered minimal to assure batch uniformity for establishing an expiration date.
Since a dosage form is a complex unit and there are continued variables in the production process, such as change in personnel, raw material lots and suppliers, and equipment, 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. Accelerated Studies When accelerated stability studies are performed, one batch may be adequate in order to establish a tentative expiration date.
This is acceptable since it is not the purpose of an accelerated test to determine batch uniformity but rather to test for kinetic degradation. The use of accelerated testing data to establish a tentative expiration dating period of greater than three years is discouraged when it is based solely on accelerated data.
Combining data compiled at room temperature and at accelerated temperature is possible to justify an expiration dating period of over two years. 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. The expiration dating period used would then be the sum of that justified individually at each storage condition. We do not believe it is reasonable to perform accelerated testing at very high temperatures for a very short time and expect to extrapolate results to a very long expiration dating period since the actual mechanism of degradation at high temperature may be different than at room temperature.
Test Intervals It is commonly recommended that stability testing be performed initially, than every three months for the first year, then every six months for the second year, and then annually thereafter. However, more frequent testing near the end of the anticipated expiration date is often likely to give better information about the actual stability of the finished product.
Nonetheless, testing at least annually is considered minimal for compliance with CGMPs. Some firms have chosen, for economical purposes, random dates to test all stability samples of a given product.

Background[ edit ] Shelf life is the recommended maximum time for which products or fresh harvested produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected or specified conditions of distribution, storage and display. If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen.
High-acid canned foods tomatoes, fruits will keep their best quality for 12 to 18 months; low-acid canned foods meats, vegetables for 2 to 5 years. Most food is still edible after the expiration date.
*Lack of an adequate number of batches (i.e., less than three) employed as the basis for either confirming a tentative expiration date or establishing the long-term stability of the product.
Health Library Drug Expiration Dates: How Accurate Are They? Since , the Food and Drug Administration FDA has required pharmaceutical manufacturers to provide expiration dates on all their products. For the majority of drugs sold in the United States, these dates range from 12 to 60 months from the date they are manufactured. Expiration dates are basically guidelines.
Your medications may expire before the expiration date if improperly stored, or they may last well beyond their expiration date, as some studies have shown. While most drugs do not become dangerous when expired, they can still pose a threat to your health. Over time, drugs lose their potency. Using a drug past its expiration date may affect its quality and effectiveness. Several factors can influence these dates, including type of active ingredients, storage conditions, preservatives, and the kind of container the drug is stored in.
The Importance of Storage Medications last only as long as their storage conditions are favorable. Drugs can lose their potency long before the expiration date if exposed to oxygen, heat, light, or humidity. In order to maintain their potency, medications should be stored in a place that is dry, cool, and dark.
Expiration Dating and Stability Testing for Human Drug Products
Expiration Date of a Cosmetic Formula Article by: Perry Romanowski One of the more frequent questions received here at Chemists Corner is about the expiration date of products. Formulators, and beauty product consumers alike, want to know how long a formula will last. Unfortunately, there is no simple answer but here are some guidelines to determining the expiration date of a cosmetic formula.
One of the primary batches of the drug product should be tested for antimicrobial preservative effectiveness (in addition to preservative content) at the end of the proposed expiration dating period. The drug product specification should include a test for preservative content, and this attribute should be tested in all stability studies. 4/
As a result, strictly following the ICH stability guidance for NCEs is unwarranted and ignores this significant database of information that is typically available for OTC drug products. It is this body of data that can often be used to justify a pre-market stability program. This 2-day intensive course will provide an understanding of how the pre-market stability programs can be successfully managed while minimizing the overall timeline.
Accelerated testing that allows the marketing of a new OTC drug product prior to the generation of long term, real time stability data and confirmation of the stability projections through an appropriate post-market stability program will also be covered. Course Director David E. Wiggins was previously Sr. Prior to joining Bayer, Mr. During this time, he has been instrumental in establishing and updating stability and method validation policy to be consistent with the changing regulatory requirements.
Wiggins has frequently lectured on stability and analytical method validation in the US, Puerto Rico, and throughout Europe. He has been active in submitting comments and validated stability-indicating analytical methods to the U. Pharmacopeia and has been an invited speaker to FDA, university, and industry conferences.
