West Pharmaceutical Services

West Pharmaceutical Services, Inc. is a global leader in the design and manufacture of technologically advanced containment and delivery systems for injectable medicines. The company partners with pharmaceutical, biotech, generic drug, and medical device companies to provide high-quality stoppers, seals, syringe/cartridge components, self-injection systems like autoinjectors/wearables, contract manufacturing services—including injection molding—and proprietary polymer-based alternatives to glass such as Daikyo Crystal Zenith®. Its products support safe storage/delivery of both small molecule drugs and complex biologics worldwide. Recent years have seen launches such as new nested vial formats and admixture devices. While it does not develop therapeutics itself or run clinical trials on drugs/devices directly targeting disease indications or molecular targets—its innovations enable safer/more effective patient care through improved drug/device compatibility.
