Two workers in warehouse double checking the supply chain As a pharmaceutical distributor, McKesson operates as one component within the pharmaceutical supply chain, which also includes drug manufacturers, regulatory bodies like the U.S. Drug Enforcement Administration (DEA) and state pharmacy boards, insurance companies, prescribing doctors and dispensing pharmacists. The company’s role is to distribute medications provided by pharmaceutical manufacturers – including opioid medications – that are ordered by healthcare entities (such as pharmacies, hospitals, clinics or nursing facilities) that are licensed by the DEA and state regulatory authorities, and only for prescriptions that are written by medical professionals registered by the DEA and licensed by state medical boards to prescribe these medications. McKesson takes seriously its role in helping to protect the safety and integrity of the pharmaceutical supply chain.
