Abstract

Disclosed are compositions and methods for treating benzodiazepine misuse and/or use disorder. A method of treating benzodiazepine misuse and/or use disorder includes administering to a subject in need thereof of an effective amount of a compound provides both partial modulator and antagonist effects at GABA A receptors.

Claims (27)

1. A method of treating benzodiazepine misuse and/or use disorder, the method comprising:

identifying a subject as having benzodiazepine misuse and/or use disorder; and

administering to the subject an effective amount of a compound providing partial modulatory effects for α2 and α3 GABA A receptor subtypes, the compound comprising the structure:

wherein the compound is administered at a dose of greater than or equal to about 0.03 mg/kg

wherein administration of the compound suppresses benzodiazepine self-administration, wherein the suppression is insurmountable and is not negated by increased benzodiazepine dosing, and

wherein administration of the compound does not precipitate benzodiazepine withdrawal in the subject.

2. The method of claim 1 , wherein the compound provides an anxiolytic effect less than that from a benzodiazepine.

3. The method of claim 1 , wherein positive reinforcing effects of the compound are less than from a benzodiazepine.

4. The method of claim 1 , wherein the compound functions to suppress the effects of a benzodiazepine independent of sedative or motor effects of the compound.

5. The method of claim 1 , wherein the compound does not induce substantial motor coordination deficits.

6. The method of claim 1 , wherein the compound provides both anxiolytic and suppression effects.

7. The method of claim 1 , wherein the compound does not induce substantial appetite suppression in the subject.

8. The method of claim 1 , wherein the compound does not substantially affect breathing frequency in the subject.

9. The method of claim 1 , wherein the compound does not substantially affect tidal volume in the subject.

10. The method of claim 1 , wherein the compound does not substantially affect minute volume in the subject.

11. A method of treating benzodiazepine misuse and/or use disorder, the method comprising:

identifying a subject as having benzodiazepine misuse and/or use disorder; and

administering to the subject an effective amount of a compound providing partial modulatory effects for α2 and α3 GABA A receptor subtypes, the compound comprising the structure:

wherein the compound is administered at a dose of greater than or equal to about 0.03 mg/kg

wherein administration of the compound results in one or both of

(i) the compound suppresses benzodiazepine self-administration, wherein the suppression is insurmountable and is not negated by increased benzodiazepine dosing,

(ii) the compound does not precipitate benzodiazepine withdrawal in the subject.

12. The method of claim 11 , wherein the compound provides an anxiolytic effect less than that from a benzodiazepine.

13. The method of claim 11 , wherein positive reinforcing effects of the compound are less than from a benzodiazepine.

14. The method of claim 11 , wherein the compound functions to suppress the effects of a benzodiazepine independent of sedative or motor effects of the compound.

15. The method of claim 11 , wherein the compound provides anxiolytic effect.

16. The method of claim 11 , wherein the compound does not induce substantial motor coordination deficits or appetite suppression in the subject, and does not substantially affect breathing frequency, tidal volume, or minute volume in the subject.
