West redefines prefillable syringe systems with Synchrony™

10 October 2025

As the global leader in primary packaging, West is setting a new benchmark in drug delivery with the launch of the West Synchrony™ Prefillable Syringe (PFS) System. Unlike traditional component-based solutions, this innovative platform uniquely integrates the syringe barrel, plunger, and needle shield/tip cap into a fully harmonized, verified system – all from a single supplier.

Designed specifically for the demanding requirements of biologics and vaccines, the West Synchrony PFS System offers a system-level solution that accelerates drug development and regulatory pathways while ensuring reliability in supply. By providing a comprehensive performance and regulatory data package, the platform streamlines syringe selection, reduces risk, and secures a dependable supply chain for combination products.

Key benefits of the West Synchrony PFS System include:

  • Design and system-level performance: one integrated verification and characterization package, ensuring form, fit, and function.
  • Comprehensive regulatory submission: one system-level drug master file and regulatory package for accelerated approval processes.
  • Single-source supply: one partner providing both made-to-stock and made-to-order solutions, with flexibility in order volumes.

By removing traditional complexities, West is enabling pharmaceutical companies to move faster, with greater predictability, toward critical development milestones. The Synchrony PFS System marks a significant step forward in prefillable syringe technology and promises to transform the landscape of injectable drug delivery.
