Drug licenses: a new model for pharmaceutical pricing.

High drug prices are a major barrier to patients' access to drugs and compliance with treatment. Yet low drug prices are often argued to provide inadequate incentives for innovation. We propose a drug-licensing model for health care, which has the promise of increasing drug use without altering patients' out-of-pocket spending, health plans' costs, or drug companies' profits. In such a model, people would purchase annual drug licenses that would guarantee unfettered access to a clinically optimal number of prescriptions over the course of a year. Using the example of statins, we illustrate how such a model could be implemented.
