Pfizer CentreSource (PCS), formerly known as Pharmacia CentreSource, has a 40-year history beginning its operation as part of the heritage Upjohn Company. This global business, headquartered in Kalamazoo, Michigan with sales offices in Europe and Asia, involves the supply of Active Pharmaceutical ingredients (API), fine chemical intermediates and contract manufacturing of finished dosage forms.
On April 16th, 2003, Pfizer Inc and Pharmacia Corporation combined operations, bringing together two of the world's fastest-growing and most innovative companies. Pfizer is the world's leading research-based pharmaceutical company. The combination expands Pfizer's global pharmaceutical leadership, broadens its product base, bolsters its research and development capacity, enlarges Pfizer's portfolio of leading consumer healthcare brands and establishes its animal health business as number one in the world. In addition, the combination expands Pfizer Global Manufacturing's global network of manufacturing facilities in the U.S., Europe, Asia and Latin America with multiple capabilities that can be utilized by PCS in fulfilling customers' needs on a global basis.
As a contract manufacturer, PCS is retained by other pharmaceutical companies to synthesize their Active Pharmaceutical Ingredient, manufacture and package finished dosage form, and if needed provide analytical and regulatory support.
