Functionality and Performance
Good patient outcomes depend upon performance of the drug product delivery system – both ease of use and reliability of delivery. Achieving these requires proper design and materials selection, and extensive testing – employing Quality by Design principles where possible. This section presents papers that consider these topics.

Data shows component conformance regarding dimensional tolerances, piston/cartridge fit, fragmentation, resealability, and initiation and travel forces.
Examination of CZ syringes delivering various fill volumes and dispensing high viscosity solutions typical of high concentration biologic formulations.
Studies were performed to compare these flange strength and dimensional variability of CZ 1mL long syringes versus glass 1mL long syringes.
1-3 mL NovaPure® plungers can deliver a more consistent injection rate and help ensure patients receive accurate dosing of their treatment regimen.
This study examines the stability of pistons in CZ cartridges at pressures similar to those of extreme transportation scenarios.
<p>The design of a plunger has a significant influence on its performance as part of a glass syringe system in an auto-injector. Performance improvements can be examined by measuring the precision and accuracy of volume and times of injection; however, break-loose and extrusion curves, while providing critical information, can be difficult to quantify. Here, we compare two 1 mL Long plungers: legacy vs plunger developed with quality by design (QbD) principles. Performance of the two plungers were evaluated by testing in a spring-loaded model auto-injector system using three different viscosity solutions. Parameters compared were: volume; time of injection; break-loose/extrusion profiles; and Area under the Curve analysis (AUC, derived by using an EXCEL® macro written to derive energy of extrusion from BLE profiles).The QbD plunger displayed a lower break-loose force than the legacy plunger and required overall less extrusion energy at lower viscosities. It also produced more consistent values in both delivery time and volume; this effect was also most pronounced with high viscosity placebo solutions. This study illustrates the principle of how syringe system performance can be affected by component design, and how applying a new way of visualizing/quantifying traditional measurement methods can shed light on component improvements.</p>
NovaPure® 1 mL Long plungers were developed with the Quality-by-Design (QbD) method for use in pre-filled syringes – especially those coupled with autoinjectors. Present work is a 1-year study examining performance with placebos of different viscosities (1, 8, 15 cps) in a laboratory configuration that replicates an autoinjector. Parameters evaluated are: delivery time; delivery volume; initiation/sustaining force. Legacy comparison is FluroTec® 2340 1 mL Long plunger.
