Benzoic acid, benzoic acid derivatives and heteroaryl carboxylic acid conjugates of hydromorphone, prodrugs, methods of making and use thereof
View Patent ↗The presently described technology provides compositions comprising aryl carboxylic acids chemically conjugated to hydromorphone (4,5-α-epoxy-3-hydroxy-17-methyl morphinan-6-one) to form novel prodrugs/compositions of hydromorphone. The hydromorphone prodrugs of the present technology have decreased side effects and decreased potential for abuse compared to unconjugated hydromorphone. The present technology also provides methods of treating patients, pharmaceutical kits and methods of synthesizing conjugates of the present technology.
1. A prodrug composition comprising at least one conjugate, wherein the at least one conjugate is 3,6-di-aspirin-hydromorphone.
2. The prodrug composition of claim 1 , wherein the at least one conjugate is used to treat narcotic or opioid abuse; to prevent narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce or prevent oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance.
3. The prodrug composition of claim 1 , wherein oral administration of the at least one conjugate results in an improved AUC and rate of release over time when compared to unconjugated hydromorphone over the same time period.
4. The prodrug composition of claim 1 , wherein oral administration of the at least one conjugate results in less variability in the oral PK profile when compared to unconjugated hydromorphone.
5. The prodrug composition of claim 1 , wherein oral administration of the at least one conjugate results in reduced side effects when compared with unconjugated hydromorphone.
6. The prodrug composition of claim 5 , wherein the reduced side effect is reduced opioid induced constipation.
7. The prodrug composition of claim 1 , wherein at least one 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.
8. The prodrug composition of claim 1 , wherein oral administration of the at least one conjugate provides a therapeutically bioequivalent AUC and/or a bioequivalent or lower C max when compared to an equivalent molar amount of unconjugated hydromorphone.
9. The prodrug composition of claim 1 , wherein intranasal or intravenous administration of the at least one conjugate provides a lower AUC and/or C max when compared to an equivalent molar amount of unconjugated hydromorphone.
10. The prodrug composition of claim 1 , wherein oral administration of the at least one conjugate provides a decreased overdose potential when compared to an equivalent molar amount of unconjugated hydromorphone.
11. The prodrug composition of claim 1 , wherein the at least one conjugate provides an increased tamper resistance when compared to unconjugated hydromorphone.
