Abstract
A growing body of research has evaluated the relationship between pharmacy benefit design and prescription drug use. These studies have consistently found that increased copayment requirements are associated with decreased use of prescription drugs,1-7 even for chronic medications to treat diabetes mellitus, hypertension, and hypercholesterolemia.7,8 These studies have looked at populations, often cross-sectionally, and focused on how policy decisions made by health plans or state payers affect use.Keywords
