Drug Distribution System refers to the entire system of medication acquisition and disbursement. In any country, opioid medications must be approved and then obtained by importation from a manufacturer or exporter in another country, and/or finished products are manufactured domestically from narcotic raw materials. A system of government-regulated distributors or wholesalers then distribute to pharmacies, hospitals, clinics, nursing homes, hospices, and palliative care programs, where duly authorized health care professionals prescribe, dispense, or administer them to patients.
