INTRODUCTION AND BACKGROUND<br />

raw ingredients through the delivery of a finished drug to the patient (see figure 1). Substandard and<br />

counterfeit products may reach patients through legitimate supply chains as happened with heparin (see<br />

case study 1) or through illicit routes.<br />

Every step in the complex pathway of the pharmaceutical supply chain—from raw materials (see sidebar<br />

1) to finished products to patient delivery—is an opportunity for adulteration. A typical pharmaceutical<br />

supply chain might proceed as follows: raw materials for a drug’s active ingredient are purchased from<br />

suppliers and undergo initial processing. Processed raw materials then move to an active active-ingredient<br />

manufacturing site, sometimes through consolidators or brokers. This site prepares the finished<br />

active ingredient and sends it to another plant, where active and inactive ingredients, provided by yet<br />

other suppliers, are combined to create the finished drug. <strong>After</strong> the finished drug is packaged and enters<br />

distribution, it may change hands between brokers and wholesalers, be repackaged into different quantities<br />

and then stored for periods of time. Eventually, the product arrives at hospitals, pharmacies and<br />

doctors’ offices, where it is dispensed to patients.<br />

Several factors offer opportunities to adulterate a product or ignore quality controls (see sidebar 2). In<br />

regions where regulation, compliance and vigilance are weak, the quest for lower-cost materials can<br />

drive the trade of substandard or falsified drug ingredients. <strong>The</strong>se may be introduced into manufacturing<br />

processes or sold as legitimate products by distributors and brokers. In countries with less developed<br />

regulatory systems than that of the United States, manufacturing standards may also be less rigorous—or<br />
