Pharmaceutical Drug Distribution Channels

This question tests basic industry knowledge of how the pharmaceutical supply chain works and how money flows through it, especially the role of pharmacies, distributors, payers, and pharmacy benefit managers. Candidates need to understand the difference between retail and mail order distribution, how negotiated pricing and reimbursement work, and why intermediaries matter in the economics of healthcare. Interviewers ask this kind of question to see whether you can connect operational structure to incentives, margins, and consolidation trends in the healthcare sector.
