Abstract: The presently described technology provides one or more compositions, preferably one or more immediate-release profile compositions, comprising aryl carboxylic acids chemically conjugated to hydrocodone (morphinan-6-one, 4,5-alpha-epoxy-3-methoxy-17-methyl), or chemically conjugated to hydromorphone (4,5,?-epoxy-3-hydroxy-17-methyl morphinan-6-one), in combination with at least one gel forming polymer; at least one disintegrant; and at least one surfactant to form novel compositions which have a decreased potential for abuse. The hydrocodone conjugate can also be combined with an analgesic, such as acetaminophen, to form a combinatorial composition that includes at least one gel forming polymer; at least one disintegrant; and at least one surfactant. The present technology also provides pharmaceutical kits and methods of synthesizing conjugates of the present technology.
