Details for Patent: 8,802,636

Title:Combination therapy for treatment of sleep apnea
Abstract: The present invention features a novel therapy for effecting weight loss which involves treating a subject with a sympathomimetic agent (e.g., phentermine or a phentermine-like drug) in combination with an anticonvulsant sulfamate derivative (e.g., topiramate) such that the subject experiences weight loss. The combination methods of the present invention also are effective against symptoms associated with Syndrome X. The invention also features pharmaceutical compositions and kits for use in the practice of these novel therapies.
Inventor(s): Najarian; Thomas (Los Osos, CA)
Assignee: Vivus, Inc. (Mountain View, CA)
Filing Date:Jan 06, 2010
Application Number:12/683,353
Claims:1. A method for treating sleep apnea in an obese patient comprising administering to the patient a therapeutically effective amount of a carbonic anhydrase inhibitor comprising an anticonvulsant sulfamate derivative in combination with a therapeutically effective amount of a sympathomimetic agent, wherein the sympathomimetic agent is phentermine.

2. The method of claim 1, wherein the carbonic anhydrase inhibitor is a compound having the structure of formula (I) ##STR00012## wherein X is CH.sub.2 or O, R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are independently H or C1-C4 alkyl, and further wherein when X is O, then R.sub.2 and R.sub.3, and/or R.sub.4 and R.sub.5, may be taken together to form a methylene dioxy linkage of the formula --O--CR.sub.6R.sub.7--O-- in which R.sub.6 and R.sub.7 are independently H or C.sub.1-C.sub.3 alkyl, or may be taken together to form a cyclopentyl or cyclohexyl ring.

3. The method of claim 2, wherein X is O, R.sub.1 is H, R.sub.2 and R.sub.3 taken together form the methylene dioxy linkage --O--CH.sub.2--O--, R.sub.4 and R.sub.5 taken together form the methylene dioxy linkage --O--CH.sub.2--O--, and the carbonic anhydrase inhibitor is topiramate.

4. The method of claim 1, wherein the carbonic anhydrase inhibitor and the sympathomimetic agent are administered simultaneously.

5. The method of claim 4, wherein the carbonic anhydrase inhibitor and the sympathomimetic agent are administered in a single pharmaceutical formulation.

6. The method of claim 5, wherein the pharmaceutical formulation comprises a controlled release dosage form.

7. The method of claim 6, wherein the controlled release dosage form provides for immediate release of the sympathomimetic agent and delayed release of the carbonic anhydrase inhibitor.

8. The method of claim 7, wherein the controlled release dosage form further provides for sustained release of the carbonic anhydrase inhibitor.

9. The method of claim 1, wherein the carbonic anhydrase inhibitor is topiramate.

10. The method of claim 9, wherein the therapeutically effective amount of topiramate is from 5 mg to 1000 mg daily and the therapeutically effective amount of phentermine is in the range of about 5 mg to 60 mg daily.

11. The method of claim 10, wherein the therapeutically effective amount of topiramate is at most about 400 mg daily.

12. The method of claim 9, wherein the phentermine and the topiramate are administered simultaneously.

13. The method of claim 12, wherein the phentermine and the topiramate are administered in a single pharmaceutical formulation.

14. The method of claim 13, wherein the pharmaceutical formulation comprises a controlled release dosage form.

15. The method of claim 14, wherein the controlled release dosage form provides for immediate release of the phentermine and delayed release of the topiramate.

16. The method of claim 15, wherein the controlled release dosage form further provides for sustained release of the topiramate.

17. The method of claim 16, wherein release of topiramate is delayed by 4 hours following release of phentermine.

18. The method of claim 16, wherein release of topiramate is delayed by 8 hours following release of phentermine.

19. The method of claim 16, wherein release of topiramate is delayed by 12 hours following release of phentermine.

20. The method of claim 16, wherein a physiologically effective blood level of topiramate is provided over a 4-hour period.

21. The method of claim 16, wherein a physiologically effective blood level of topiramate is provided over an 8-hour period.

22. The method of claim 16, wherein a physiologically effective blood level of topiramate is provided over a 12-hour period.

23. The method of claim 11, wherein the therapeutically effective amount of topiramate is at most about 250 mg daily.

24. The method of claim 11, wherein the therapeutically effective amount of phentermine is in the range of about 5 mg to 15 mg daily.

25. The method of claim 23, wherein the therapeutically effective amount of phentermine is in the range of about 5 mg to about 15 mg daily.
