Even as pharma technology evolves, and payers argue over reimbursement practices throughout healthcare, drug wholesaling is a thriving business. On the surface, the US pharmaceutical supply chain is fairly quiet. Every day, some 10 million prescriptions are delivered to patients via clinics or pharmacies, usually through the efforts of the wholesaler sector. Wholesalers’ trade association, the Healthcare Distribution Alliance (HDA), says that its 39 members (up several from a couple years ago) are responsible for 95% of primary distribution—i.e., taking delivery from over 1,500 suppliers, and ownership of the drugs, to be distributed to some 300,000 locations around the country.
