The Pharmaceutical Cartridges Market can be segmented based on material, delivery device compatibility, capacity, therapeutic area, end user, and region.

By material, the market includes glass and engineering plastics. Glass, particularly Type I borosilicate glass, held approximately 67.8% of the market in 2025. Engineering plastics such as COC and COP are gaining market share because they offer lightweight construction and strong break resistance.

By delivery device compatibility, reusable pen injectors represented approximately 46.6% of revenue in 2025. Autoinjectors and wearable on-body pumps are also expanding as biologic therapies increasingly move toward self-administration.

By capacity, smaller cartridges remain important for insulin and standard biologic applications, while larger-volume cartridges are gaining attention for wearable delivery systems and high-volume subcutaneous therapies.

By therapeutic area, diabetes represented the leading segment with a 25.8% share in 2025. Oncology is expected to register rapid growth as selected therapies increasingly explore subcutaneous administration.

By end user, pharmaceutical companies accounted for the largest share, while contract manufacturing and development organizations are expected to experience strong growth as pharmaceutical companies increasingly outsource manufacturing and fill-finish operations.

Regionally, North America held the largest share, while Asia-Pacific is projected to be the fastest-growing regional market through 2035.
