Abstract

Methods for the treatment of systemic disorders treatable with mast cell stabilizers, including mast cell related disorders, are provided.

Claims

1. A method of administering cromolyn sodium to a patient in need thereof, comprising administering to the patient a pharmaceutical composition comprising cromolyn sodium using a device that produces an aerosol of the pharmaceutical composition exhibiting a respirable fraction (≤

5 μ

m) of at least about 60%, and wherein administration of the pharmaceutical composition comprising from about 40 mg to about 80 mg of cromolyn sodium to the subject produces in the subject an AUC<sub>(0-∞

)</sub> of the cromolyn sodium greater than about 120 ng*hr/mL.

2. The method of claim 1, wherein administration of the pharmaceutical composition to the subject by means of the device produces in the subject an AUC_(0-∞

) of the cromolyn sodium greater than about 200 ng*hr/mL.

3. The method of claim 1, wherein administration of the pharmaceutical composition to the subject by means of the device produces in the subject an AUC_(0-∞

) of the cromolyn sodium greater than about 330 ng*hr/mL.

4. The method of claim 1, wherein administration of the pharmaceutical composition comprising 80 mg of cromolyn sodium to the subject produces in the subject an AUC_(0-∞

) of the cromolyn sodium greater than about 525 ng*hr/mL.

5. The method of claim 1, wherein the device is a nebulizer.

6. The method of claim 5, wherein the nebulizer is a high-efficiency nebulizer.

7. The method of claim 1, wherein the device is a dry powder inhaler.

8. The method of claim 1, wherein the administration of the pharmaceutical composition to the subject produces in the subject a C_max of the cromolyn sodium greater than about 55 ng/mL.

9. The method of claim 8, wherein the device is a nebulizer.

10. The method of claim 9, wherein the device is a high-efficiency nebulizer.

11. The method of claim 8, wherein the device is a dry powder inhaler.

12. The method of claim 1, wherein the pharmaceutical composition comprises about 40 mg of cromolyn sodium.

17. The method of claim 12, wherein administration of the pharmaceutical composition to the subject by means of the device produces in the subject an AUC_(0-∞

) of the cromolyn sodium greater than about 230 ng*hr/mL.

13. A method of administering cromolyn sodium to a patient in need thereof, comprising administering to the patient a pharmaceutical composition comprising cromolyn sodium using a device that produces an aerosol of the pharmaceutical composition exhibiting a respirable fraction (≤

5 μ

m) of at least about 60%, and wherein administration of the pharmaceutical composition comprising from about 40 mg to about 80 mg of cromolyn sodium to the subject produces in the subject a C_max of the cromolyn sodium greater than about 55 ng/mL.

14. The method of claim 13, wherein administration of the pharmaceutical composition to the subject produces in the subject a C_max of the cromolyn sodium greater than about 80 ng/mL.

15. The method of claim 13, wherein administration of the pharmaceutical composition to the subject produces in the subject a C_max of the cromolyn sodium greater than about 150 ng/mL.

16. The method of claim 13, wherein administration of the pharmaceutical composition comprising 80 mg of cromolyn sodium to the subject produces in the subject a C_max of the cromolyn sodium greater than about 120 ng/mL.

18. The method of claim 13, wherein the device is a nebulizer.

19. The method of claim 18, wherein the device is a high-efficiency nebulizer.

20. The method of claim 13, wherein the device is a dry powder inhaler.
