Title: | Benzoic acid, benzoic acid derivatives and heteroaryl carboxylic acid conjugates of hydrocodone, prodrugs, methods of making and use thereof |
Abstract: | 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. |

Claims: | 1. A composition comprising a conjugate, wherein the conjugate is nicotinate-hydrocodone (nicotinate-HC) having the following structure: ##STR00025## 2. The composition of claim 1, wherein the conjugate is used to treat narcotic or opioid abuse; to reduce narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance. 3. The composition of claim 1, wherein the conjugate exhibits an improved AUC and rate of release over time when compared to unconjugated hydrocodone over the same time period; exhibits less variability in the oral PK profile when compared to unconjugated hydrocodone; or has reduced side effects when compared with unconjugated hydrocodone. 4. The composition of claim 1, wherein the conjugate is provided in a dosage form selected from the group consisting of: a tablet, a capsule, a caplet, a suppository, a troche, a lozenge, an oral powder, a solution, an oral film, a thin strip, a slurry, and a suspension. 5. The composition of claim 1, wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC when compared to unconjugated hydrocodone. 6. The composition of claim 1, wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and C.sub.max when compared to an equivalent molar amount of unconjugated hydrocodone. 7. The composition of claim 1, wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and a lower C.sub.max when compared to an equivalent molar amount of unconjugated hydrocodone. 8.
