Abstract

A method of delivering a substance, such as one or more of a triptan, a nasal steroid or carbon dioxide gas, to the nasal cavity of a subject, in particular for the treatment of headaches, for example, migraine, or rhinosinusitis, for example, chronic rhinosinusitis, optionally with polyps, the method comprising the steps of fitting a nosepiece to one nostril of the subject, delivering the substance through the nosepiece to the posterior region of the nasal cavity of the subject.

Claims

1. A method of therapeutically treating a patient, comprising:

administering, in a first step, a therapeutic agent to the patient; and

delivering, in a second step, to a location at an interior of a nasal passage of the patient a therapeutic amount of at least one of carbon dioxide or a pH adjusting material, wherein the first step is performed separately of the second step and or after before and the second step.

2. The method of claim 1, wherein the first step is performed before the second step.

3. The method of claim 1, wherein the first step is performed after the second step.

5. The method of claim 1, wherein the location includes an upper posterior region of the nasal passage.

6. The method of claim 1, wherein the therapeutic agent includes sumatriptan, optionally in the form of sumatriptan succinate, optionally administered as a powder aerosol.

7. The method of claim 1, wherein the therapeutic agent includes a topical steroid, optionally fluticasone, optionally in the form of fluticasone propionate, optionally administered as a liquid aerosol.

12. The method of claim 1, wherein the second step adjusts a pH in the nasal passage location by an amount ranging from about 0.01 to about 0.5 pH units.

13. The method of claim 12, wherein the amount ranges from about 0.1 to about 0.2 pH units.

14. The method of claim 1, wherein the second step comprises delivering a concentration of carbon dioxide from about 1% to about 10% vol/vol carbon dioxide.

15. The method of claim 14, wherein the concentration of carbon dioxide is from about 5% to about 6% vol/vol carbon dioxide.

16. The method of claim 1, wherein the delivering comprises:

placing a mouthpiece into a mouth of the patient and a nosepiece into a nostril of the patient;

the patient exhaling a breath into the mouthpiece to create a fluid flow out of the nosepiece; and

directing the fluid flow to the nasal passage location.

17. The method of claim 16, wherein the delivering further comprises:

adjusting a pH at the nasal passage location by controlling the fluid flow.

18. The method of claim 17, wherein the controlling of the fluid flow includes at least one of controlling a duration, a rate, a pressure, and a composition of the fluid flow.

19. The method of claim 18, wherein the fluid flow is controlled to have a duration in a range of from about 2 to about 3 seconds.

20. The method of claim 19, wherein the fluid flow is controlled to have a rate of at at least 10 L/min, optionally at least 20 L/min, and optionally about 30 L/min.

21. The method of claim 16, wherein the delivering further comprises:

placing the nosepiece into a second nostril of the patient;

the patient exhaling a breath into the mouthpiece to create a second fluid flow out of the nosepiece; and

directing the second fluid flow to a second nasal passage location.

22. A method for increasing a therapeutic effect of a pharmaceutical agent delivered to a patient, comprising:

delivering, in a first step, a fluid flow to a nasal passage of the patient to deliver about 5% to about 6% vol/vol carbon dioxide to a posterior region of the nasal passage; and

administering, in a second step, a dose of the pharmaceutical agent to the patient;

wherein the second step is performed separately to the first step.

23. The method of claim 22, wherein the delivering includes lowering a pH of the posterior region of the nasal passage.

24. The method of claim 22, wherein the pharmaceutical agent includes sumatriptan, optionally in the form of sumatriptan succinate, optionally administered as a powder aerosol.

25-29. -29. (canceled)

30. A method of treating a patient, comprising:

delivering, in a first step, a concentration of about 5% to about 6% vol/vol carbon dioxide to an upper posterior region of a nasal passage of the patient to lower a pH of the upper posterior region of the nasal passage by at least about 0.1 pH units to provide a therapeutic or pharmacokinetic effect; and

administering, in a second step, a therapeutic agent to the patient at least one of orally, intranasally, intravenously, and sub-cutaneously;

wherein the second step is performed separately to the first step.

32. The method of claim 30, wherein the administering includes administering a dose of sumatriptan powder intranasally.

33. The method of claim 32, the dose of sumatriptan includes less than 20 mg of a sumatriptan powder, optionally about 16 mg of sumatriptan powder, optionally in the form of sumatriptan succinate.

39. The method of claim 30, wherein the therapeutic or pharmacokinetic effect treats at least one of migraine and allergic rhinitis.

40. The method of claim 30, wherein the delivering includes substantially closing a soft palate of the patient.
