Lecture 2—What Is a Formulary, Anyway? (Or the Cliff Notes Version of Drug Stewardship and Expense Control)

A formulary is the product of an evaluative process, the formulary system, conducted by an expert panel that both sanctions and guides the selection, prescription, administration, and monitoring of pharmaceuticals and related items for a given environment. An expert panel, often called the Pharmacy and Therapeutics Committee (P&T), is a group of pharmacists, physicians, nurses, and administrators assembled for the purpose of providing guidance and validation for pharmaceutical utilization in a given organization. Expert panels became prominent because of qualitative and quantitative changes in drug production and marketing strategies employed by industry, the expansion of public health sector medicine, and organized, macro-level drug control systems. It could be argued that, as a clinical instrument, the formulary is predicated on the role pharmacy is perceived to play in actual direct patient care. In this lecture, the concept and defining characteristics of a formulary (the perspective of an expert panel, differences in the environment of application, and interprofessional relationships), the modifiers used to describe a formulary, which modifiers enhance or distract from its meaning, and the outlook for comprehensive and objective evaluation through the formulary mechanism are discussed.
