Medical grade TPE for eye drop packaging

The ophthalmic squeeze dispenser (OSD) from Aptar Pharma is in widespread use as dispenser for eye drops that contain no preservatives.

The latest evolution of the device has several functional parts manufactured using a newly developed Thermolast M TPE from Kraiburg TPE. The TPE components come into direct contact with the medical eye drop formulation. Aptar Pharma requires classification as a medical grade plastic in compliance with the stringent regulations for the primary packaging of sensitive medications.

Kraiburg TPE has been cooperating with Aptar Pharma for a number of years. “Early integration in the project allowed us to contribute our full range of know-how and experience and to offer our customer a TPE solution that fulfils all requirements, including the specified sterilisation”, says Oliver Kluge, Medical Product Consultant at Kraiburg TPE. Aptar Pharma’s OSD is, according to the company, the only repeated-use dosing system thus far approved by the FDA for liquid medications that do not contain preservatives. The design contains no metal parts whatsoever in the drug flux and is therefore also suitable for very sensitive formulations. The purely mechanical functioning principle of the seal membrane and spring unit eliminates the possibility of microbiological contamination of the liquid.
