Nivagen Pharmaceuticals

Nivagen Pharmaceuticals is a specialty pharmaceutical company focused on the development, manufacturing, and marketing of generic and specialty drugs, with a particular emphasis on ready-to-use (RTU) sterile injectables. The company operates a state-of-the-art aseptic manufacturing facility in Sacramento, California, producing various dosage forms including IV bags, vials, pre-filled syringes, and cartridges. In January 2026, Nivagen was acquired by PAI Pharma, a portfolio company of Olympus Partners. This acquisition was designed to strengthen domestic pharmaceutical manufacturing, address drug shortages in the U.S. healthcare system, and expand PAI's hospital-focused therapy offerings by integrating Nivagen's robust pipeline and manufacturing infrastructure.
