Benzoic acid, benzoic acid derivatives and heteroaryl carboxylic acid conjugates of oxymorphone, prodrugs, methods of making and use thereof

Abstract:

The presently described technology provides compositions comprising aryl carboxylic acids and, for example NSAIDs, chemically conjugated to oxymorphone (4,5-.alpha.-epoxy-3,14-dihydroxy-17-methylmorphinan-6-one) to form novel prodrugs/compositions of oxymorphone, including benzoates, salicylates, propionates, fenamates, and acetates, which have a decreased potential for abuse of oxymorphone. The present technology also provides methods of treating patients, pharmaceutical kits and methods of synthesizing conjugates of the present technology.
