Abstract

Official abstract text for this publication.

The presently described technology provides compositions comprising aryl carboxylic acids chemically conjugated to hydrocodone (morphinan-6-one, 4,5-alpha-epoxy-3-methoxy-17-methyl) to form novel prodrugs/compositions of hydrocodone, including benzoates and heteroaryl carboxylic acids, which have a decreased potential for abuse of hydrocodone. The present technology also provides methods of treating patients, pharmaceutical kits and methods of synthesizing conjugates of the present technology.
