In pharmaceutical compounding (503A pharmacies) and manufacturing (503B outsourcing facilities), maintaining precise drug pH, sterility assurance levels (SAL 10⁻⁶), and product integrity throughout shelf life is non-negotiable for patient safety and FDA compliance. Glass vials serve as the primary containment system. Still, substandard vials can leach alkali ions that elevate pH, compromise hydrolytic stability, or create particulate contamination risks during filling and storage.
This technical guide examines how Type I borosilicate glass vials—specified under USP 660 and ISO 8362-1—preserve critical quality attributes (CQAs) in sterile injectables, lyophilized biologics, and small-volume parenterals. Compounding pharmacists, process engineers, and quality assurance professionals will find practical selection criteria, regulatory references, and risk mitigation strategies aligned with USP 797, USP 800, and 21 CFR 211 cGMP requirements.
