The Ritedose Corporation

The Ritedose Corporation, founded in 1995 and headquartered in Columbia, South Carolina, has established itself as the largest CDMO specializing in sterile Blow-Fill-Seal (BFS) technology in the United States. The company operates a dual business model, providing high-speed, scalable contract manufacturing services to partners while also producing and distributing a portfolio of generic pharmaceuticals, notably claiming the largest nebulized drug portfolio in the U.S. With a production capacity of over 1.8 billion doses annually from a 100,000+ square-foot facility, Ritedose is a critical player in ensuring a stable supply of essential, sterile unit-dose medications and addressing drug shortages.

Industry-leading Blow-Fill-Seal (BFS) aseptic manufacturing technology. This automated, closed-system process forms, fills, and seals sterile unit-dose containers from polymer in one continuous operation, minimizing contamination risk.

Ritedose competes with large, diversified CDMOs (e.g., Catalent, Lonza) that offer vial-filling and other aseptic technologies, and with other BFS specialists globally. Its claim as the largest U.S. BFS CDMO and its integrated generics division provide a unique competitive position, combining specialized technology with volume-scale manufacturing.
