Text: 7 We believe it helpful to describe at the outset the place of generics in the drug industry. Generic drugs are chemically identical versions of branded drugs and cannot be put on the market until the patent on the branded drug has expired. Generic drugs are typically sold at a substantial discount from the name brand drug. To market and distribute such a drug in the United States, manufacturers must receive approval from the United States Food and Drug Administration (FDA). A generic manufacturer files an Abbreviated New Drug Application with the FDA to establish that its drug is therapeutically equivalent to the innovator drug. 8 As part of the approval process, pharmaceutical companies must identify the supplier of the active pharmaceutical ingredient they intend to use in manufacturing the product. Ingredient suppliers, such as ACIC/Brantford, submit a Drug Master File (Master File) to the FDA which summarizes the equipment, manufacturing process, and control measures used to prepare the particular ingredient. The supplier submits a reference letter to the FDA on behalf of a particular manufacturer, stating that it will follow the methods in its Master File for that manufacturer. 9 The parties dispute the effect of a Master File reference letter. Plaintiffs maintain it is industry practice for such a reference letter effectively to bind a supplier actually to provide the chemical to the manufacturer. They also state that manufacturers and suppliers generally do business in reliance on oral agreements. Defendants respond that the filing of a reference letter is nothing more than a preliminary action that creates no obligation on the part of the supplier. 10 The FDA rates a generic product as AB equivalent if it is a bioequivalent to the branded product. The generic warfarin sodium products currently on the market all have been rated as AB equivalent to the branded drug Coumadin. Despite this rating, generic drugs may have some minor differences from the branded drug, such as the water content, crystalline structure, and particle size of the active ingredient.
