Potential reasons for altering the recommended storage conditions are alternative dosage forms or diverse product types such as biotechnological/biological drugs.ДЇor long-term studies, the testing frequency should be sufficient to establish the stability profile of the product. Variations of storage conditions may be acceptable if the manufacturer can justify the change based on product knowledge or other factors. Accelerated conditions are 40вЊ В± 2вЊ/75% RH В± 5% RH. The storage condition for long-term (real-time) is 25вЊ В± 2вЊ/60% Relative Humidity (RH) В± 5% RH. Suggested storage conditions may vary in other climatic zones throughout the world. The recommended storage conditions stipulated in the ICH guidance were developed based on the climates of the three regions represented: US, Europe, and Japan. The drug product should be manufactured using different batches of the drug substance. Two of the three batches should be at least pilot scale batches, and the third one can be smaller if justified. The substance should be stored and tested using the same packaging and materials as the intended finished product.ДЇor a drug product, data from stability studies should be provided on at least three primary batches of the same formulation and packaged in the same container closure system as intended for distribution.

A вЂњpilot scaleвЂќ batch is one produced by a procedure fully representative of and simulating that to be applied to a full production scale batch. The batches should be manufactured to a minimum of pilot scale.

The primary stability testing guidance document for drug substances and products marketed in Japan, Europe, and the United States is the International Conference on Harmonization (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use, ICH Harmonized Tripartite Guideline, Stability Testing of New Drug Substances and Products вЂ“ Q1A(R2).ДЇor a drug substance stability study, the ICH guidance recommends utilizing a minimum of three batches of product. Acceptance criteria should be stipulated before initialization of the study, and if a product fails to meet specifications at any time point, the stability study may be halted and restarted after reformulation or other modifications have occurred. After the established re-test period has elapsed, a manufacturer may use a drug substance only after performing additional specification testing, the material passes inspection, and the substance is distributed soon after meeting acceptance criteria.ДЇor a drug product, stability testing determines the shelf-life of the product by establishing the duration for which the product is safe to use and retains therapeutic value according to the level of the active ingredient(s).Дuring a stability study, materials are stored at various temperatures and humidity conditions, samples are pulled at predetermined time points and subjected to a battery of tests that may include: an identification test, assay, physical tests, microbiological limits, and preservative effectiveness testing, using appropriately validated methods and/or recognized compendial methods. A drug вЂњproductвЂќ is the formulated mixture of the drug substance and excipients comprising the final marketed dosage form.ДЇor a drug substance, stability testing determines the вЂњre-test period,вЂќ defined as the timeframe during which the drug substance is expected to remain within its specification, and remains viable for the manufacture of a given drug product. A drug вЂњsubstance,вЂќ often referred to as an Active Pharmaceutical Ingredient (API), is defined as the unformulated material that may subsequently be formulated with excipients to produce a dosage form. Stability testing is utilized to determine if the quality of a drug substance or drug product is altered over time by various environmental factors, such as light, temperature, and humidity.
