Overview
ISO 11418-4:2005, developed by the International Organization for Standardization (ISO), sets out the specifications for tablet glass bottles intended for pharmaceutical preparations. This document defines the design, dimensions, materials, and essential requirements for glass bottles used as primary packaging in direct contact with solid or liquid pharmaceutical products, except for those intended for parenteral (injectable) use. Ensuring the quality and integrity of primary packaging is critical in maintaining the safety, potency, and stability of medicines throughout their shelf life.
Key Topics
-
Design and Dimensions
The standard specifies the essential dimensions and tolerances for tablet glass bottles to ensure compatibility with closure systems and consistency across production batches.
-
Material Requirements
Tablet glass bottles must be produced from either colourless (cl) or amber (br) borosilicate or soda-lime-silica glass. These materials are selected based on their hydrolytic resistance as defined in referenced ISO standards, helping to safeguard drug stability.
-
Hydrolytic Resistance
The standard requires strict compliance with hydrolytic resistance testing (in accordance with ISO 4802-1 or ISO 4802-2) to minimize interaction between the glass and the pharmaceutical products, reducing potential contamination risks.
-
Load and Thermal Shock Resistance
Tablet glass bottles must withstand vertical load (as tested per ISO 8113) and endure thermal shock with a temperature difference of 42°C (as outlined in ISO 7459), ensuring their integrity during handling and transport.
-
Marking and Identification
Each bottle should include markings such as the manufacturer’s trademark, reference numbers, and optional nominal volume, ensuring traceability and product identification.
Applications
-
Primary Packaging for Pharmaceuticals
ISO 11418-4:2005 is directly applicable to the pharmaceutical industry, guiding manufacturers and packagers in selecting compliant tablet glass bottles for pills, tablets, and certain liquid formulations.
-
Regulatory Compliance
Pharmaceutical manufacturers, quality assurance professionals, and regulatory bodies rely on this standard to ensure that packaging materials used in direct contact with drugs meet safety and performance requirements.
-
Supply Chain and Procurement
Purchasing departments and suppliers use the specifications for clear tendering and procurement processes, helping to guarantee the compatibility and safety of packaging selections.
-
Product Development
R&D and design teams utilize ISO 11418-4:2005 to develop packaging solutions that maintain drug stability and meet global shipment requirements.
