  McKesson Corp. said Wednesday it has revamped its business units, a move the company said will help it operate more efficiently 


  The distributor of pharmaceuticals and other health products will start using four reportable segments: 


  U.S. Pharmaceutical and Specialty Solutions segment will focus on wholesale drug distribution and technology products for retail pharmacies, health systems and other clients, the company said, as well as U.S. oncology offerings. 


  Prescription Technology Solutions encompasses the company's work with biopharma and life sciences partners and patients. 


  International covers McKesson Canada's and McKesson Europe's drug distribution services, specialty pharmacy, retail and infusion care services in those markets. 


  The fourth segment, Medical-Surgical Solutions, is unaffected by the realignment, the company said. 


  "McKesson expects to transition to financial reporting under the new four-segment structure for periods commencing after the first quarter of fiscal 2021," the company added.
