The drug discrimination assay: Interpretative value of partial generalization for drug schedule control actions

Abstract

The U.S. Food & Drug Administration (FDA) has issued a final guidance document on the preclinical determination of abuse potential that must be conducted in animals for all new molecular entities (NMEs) submitted for a new drug application (NDA). Under statutory restrictions government guidance documents serve only as a guide or an expression of the agency's current thinking on the topic. Guidelines do not legally bind the agency or its registrants to any content in the guidance. There are no statutory (legal) descriptions of what study designs or methodology must be submitted to the Drug Enforcement Administration with respect to drug scheduling review. This paper describes the utility of an alternate method used, worldwide, to assess the internal subjective effects of drugs to predict the abuse liability that provides additional information to address the relative aspects of that liability.
