title: Patients who do not respond to the "usual" dose: why Terry fell off the dose-response curve.
abstract: Clinical trials are aimed at determining what happens in the "usual" patient; however, clinicians are interested in what happens in their patients even if they are not usual. The usual dose-response relationship is determined as part of the drug development process required for approval of a new drug. However, clinicians are likely to encounter patients who "fall off" the usual dose-response curve because they are either sensitive or resistant to the beneficial (efficacy) or adverse effects of a drug. This column is the first in a series that will examine why specific patients fall off the usual dose-response curve and how clinicians can manage such patients when they encounter them. This column discusses what a dose-response curve is, how it is determined, and why it is clinically important.
