Filing Date:Jul 08, 2014
Application Number:14/326,075
Claims:1. A method of treating insulin resistance, comprising: identifying a subject having a blood-glucose condition characterized by insulin resistance in need of treatment, wherein the condition is Type 2 diabetes and the subject is treated with insulin; and administering to the subject an amount of a composition that is effective to treat the insulin resistance, wherein the composition comprises naltrexone or a pharmaceutically acceptable salt thereof and bupropion or a pharmaceutically acceptable salt thereof, wherein the amount of the naltrexone or pharmaceutically acceptable salt thereof is about 25 mg per day to about 50 mg per day, and wherein the amount of the bupropion or pharmaceutically acceptable salt thereof is about 200 mg per day to about 400 mg per day; obtaining a measurement of the subject's blood glucose level following treatment with said composition; and decreasing the amount of insulin used in the insulin treatment in response to the measurement of the subject's blood glucose level following treatment with said composition.

2. The method of claim 1, wherein the naltrexone or pharmaceutically acceptable salt thereof is administered to the subject separately from the bupropion or pharmaceutically acceptable salt thereof.

3. The method of claim 1, further comprising providing dietary instructions to the subject.

4. The method of claim 1, wherein at least one of the naltrexone or pharmaceutically acceptable salt thereof and the bupropion or pharmaceutically acceptable salt thereof is in a sustained release formulation.

5. The method of claim 1, wherein each of the naltrexone or pharmaceutically acceptable salt thereof and the bupropion or pharmaceutically acceptable salt thereof is in a sustained release formulation.

6. The method of claim 1, wherein the naltrexone or pharmaceutically acceptable salt thereof and the bupropion or pharmaceutically acceptable salt thereof are in a single oral dosage form.

7. The method of claim 6, wherein the single oral dosage form is in the form of a tablet, pill, or capsule.

8. A method of treating insulin resistance, comprising: identifying a subject having a blood-glucose condition characterized by insulin resistance in need of treatment, wherein the condition is Type 2 diabetes and the subject is treated with insulin; and administering to the subject an amount of a composition that is effective to treat the insulin resistance, wherein the composition comprises a sustained-release naltrexone formulation and a sustained-release bupropion formulation or pharmaceutically acceptable salts thereof, wherein the amount of the naltrexone or pharmaceutically acceptable salt thereof is about 25 mg per day to about 50 mg per day, and wherein the amount of the bupropion or pharmaceutically acceptable salt thereof is about 200 mg per day to about 400 mg per day, and wherein the composition is in a single oral dosage form; obtaining a measurement of the subject's blood glucose level following treatment with said composition; and decreasing the amount of insulin used in the insulin treatment in response to the measurement of the subject's blood glucose level following treatment with said composition.

9. The method of claim 8, wherein the single oral dosage form is in the form of a tablet, pill, or capsule.

10. The method of claim 1, wherein the amount of the naltrexone or pharmaceutically acceptable salt thereof is about 25 mg per day to about 38 mg per day, and wherein the amount of the bupropion or pharmaceutically acceptable salt thereof is about 300 mg per day to about 400 mg per day.

11. The method of claim 10, wherein the subject is obese.

12. The method of claim 1, wherein the subject is obese.

13. The method of claim 8, wherein the amount of the naltrexone or pharmaceutically acceptable salt thereof is about 25 mg per day to about 38 mg per day, and wherein the amount of the bupropion or pharmaceutically acceptable salt thereof is about 300 mg per day to about 400 mg per day.

14. The method of claim 13, wherein the subject is obese.

15. The method of claim 8, wherein the subject is obese.

16. The method of claim 1, wherein said amount of bupropion or pharmaceutically acceptable salt thereof is in a divided dose for administration twice a day, and wherein said amount of naltrexone or pharmaceutically acceptable salt thereof is in a divided dose for administration twice a day.

17. The method of claim 9, wherein said amount of bupropion or pharmaceutically acceptable salt thereof is in a divided dose for administration twice a day, and wherein said amount of naltrexone or pharmaceutically acceptable salt thereof is in a divided dose for administration twice a day.
