Role of Extractables and Leachables in Container Qualification

Extractables and leachables (E&L) play a pivotal role in determining the safety and suitability of pharmaceutical packaging. These studies help identify harmful substances that may migrate from the container closure system into the drug product during storage and use. Regulatory authorities such as the USFDA, EMA, and WHO mandate comprehensive E&L assessments to ensure packaging…

Packaging and Containers, Pharmaceutical Containers and Closures for Stability

Include Headspace Oxygen Testing Where Required in Stability Studies

Understanding the Tip: Why headspace oxygen matters in pharmaceutical stability: Many pharmaceutical formulations—especially biologics, injectables, and oxygen-sensitive actives—can degrade in the presence of oxygen. Headspace oxygen testing assesses the level of oxygen within the sealed container and evaluates whether packaging systems effectively prevent ingress over time. This is crucial for maintaining chemical integrity, physical appearance,…

Include Container Torque and Closure Integrity Testing in Stability

Understanding the Tip: Why closure integrity matters during stability studies: Container-closure systems serve as the first line of protection for pharmaceutical products. If the seal loosens or fails during storage, it can lead to evaporation, contamination, degradation, or even microbial ingress. Torque and closure integrity testing ensure that screw caps, crimped seals, flip-off caps, and…

Packaging Selection Tips to Prolong Drug Shelf Life

Pharmaceutical packaging is more than a protective shell—it plays a critical role in maintaining product stability and extending shelf life. Selecting the optimal packaging material and configuration can mitigate degradation risks from light, moisture, temperature, and oxygen exposure. This tutorial explores essential tips and considerations for packaging selection that pharma professionals should apply during product…

Factors Affecting Drug Shelf Life (Storage Conditions, Container, Light, etc.), Shelf Life and Expiry

Ensure Glass Vials Meet USP <660> Standards Before Stability Testing

Understanding the Tip: Why glass container compliance matters in stability testing: Glass vials and bottles are widely used for parenteral, oral, and ophthalmic drug products. If the container does not meet the chemical and thermal specifications of USP <660> (or equivalent), there is a risk of alkali leaching, surface reactivity, particulate formation, or contamination—especially over…

Stability Study Tips

Include Stability Samples in Mock Transport to Simulate Distribution Stress

Understanding the Tip: Why simulate transport conditions during stability studies: Pharmaceuticals often travel through complex distribution channels—facing vibration, shocks, temperature spikes, and humidity fluctuations. While chamber stability simulates storage, it doesn’t capture the physical stress of transport. Including stability samples in mock shipments replicates these distribution hazards and verifies product resilience before market launch. This…

Stability Study Tips

Evaluate Moisture Permeability of Packaging in Stability Testing

Understanding the Tip: Why moisture permeability matters in pharmaceutical packaging: Moisture ingress through packaging is a leading cause of chemical and physical instability—especially for hygroscopic APIs, effervescent tablets, and biologics. Even seemingly sealed containers may allow water vapor transmission over time. In stability studies, ignoring packaging permeability can result in underestimated degradation risks and falsely…

Stability Study Tips

Conduct Label Migration Studies for Samples in Contact with Printed Packaging

Understanding the Tip: What is label or ink migration in packaging: Label migration refers to the transfer of chemicals—particularly inks, adhesives, and coatings—from printed packaging materials into the pharmaceutical product. This is a concern when the product is stored in direct contact with printed surfaces, such as blisters, pouches, or sachets without internal barriers. Migrated…

Perform Container-Closure Integrity Testing for Long-Term Stability Packaging

Understanding the Tip: What is container-closure integrity testing (CCIT): CCIT is a critical evaluation of whether the packaging system effectively seals the pharmaceutical product against environmental ingress. It ensures protection from contaminants such as moisture, oxygen, and microbes, especially over extended storage periods. Whether for sterile injectables, capsules, or biologics, a packaging failure can result…
