Testing is performed to assess the chemical safety of packaging systems and materials.

USP <661>, <661.1> and <661.2> detail the test programs required for plastic packaging systems and their materials of construction for pharmaceuticals. USP <661> is valid until 2020 and early adoption of <661.1> and <661.2> is allowed before then.

USP <661.1> and <661.2> testing

The testing required for <661.1> is dependent on the material and may include extractions into organic solvents, acids, bases and/or water. This is then followed by analysis and/or physicochemical testing, depending on the material. Analysis techniques include: GC, LC, titration, TOC, acidity or alkalinity etc.

USP <662.2> includes an evaluation of the materials, testing and may incorporate extractables and leachables studies as part of a chemical safety assessment.

Products and materials tested:

USP <661.1>

 USP <661.2>

All plastic materials used in the construction of pharmaceutical packaging, including: COC, PE, PP, polyamide 6, polycarbonate, PET, PETG, EVA, PVC, plasticized PVC and other “unaddressed materials”

Pharmaceutical packaging covers all packaging types, including: inhalation, nasal, parenteral, oral, topical etc.
