Abstract

The present disclosure relates to methods of treating idiopathic hypersomnia with oxybate, preferably sodium oxybate.

Claims (36)

1 . A method of treating idiopathic hypersomnia in a patient in need thereof, the method comprising:

administering a therapeutically effective amount of sodium oxybate to the patient.

2 . A method of treating idiopathic hypersomnia in a patient in need thereof, the method comprising:

administering a therapeutically effective amount of sodium oxybate to the patient,

wherein the sodium oxybate is administered as a liquid and the concentration of sodium oxybate in the liquid is about 500 mg/mL.

3 . The method of claim 1 , wherein the sodium oxybate is administered as a liquid, and the concentration of the sodium oxybate in the liquid is from 350 mg/ml-650 mg/ml.

4 . The method of claim 1 , wherein the method comprises:

(a) administering an initial daily dose of the sodium oxybate to the patient and

(b) titrating the dose to provide the therapeutically effective amount of the sodium oxybate.

5 . The method of claim 4 , wherein the initial daily dose is from about 3 g to about 4.5 g of the sodium oxybate.

6 . The method of claim 4 , wherein the titration step (b) comprises administering ascending doses of the sodium oxybate.

7 . The method of claim 1 , wherein about 4.5 g to 9.0 g of the sodium oxybate is administered per day.

8 . The method of claim 1 , wherein the sodium oxybate is administered twice per day or once a day.

9 . The method of claim 1 , wherein about 4.5 g, about 6 g, about 7.5 g, or about 9 g of the sodium oxybate is administered per day.

10 . The method of claim 1 , wherein about 3 g, about 3.75 g, or about 4.5 g of the sodium oxybate is administered per day.

11 . The method of claim 1 , wherein the sodium oxybate is administered at bedtime.

12 . The method of claim 2 , wherein the method comprises:

(a) administering an initial daily dose of the sodium oxybate to the patient and

(b) titrating the dose to provide a therapeutically effective amount of the sodium oxybate.

13 . The method of claim 12 , wherein the initial daily dose is from about 0.5 g to about 4.5 g of the sodium oxybate administered per day.

14 . The method of claim 12 , wherein the titration step (b) comprises administering ascending doses of the sodium oxybate.

15 . The method of claim 14 , wherein dose is increased by about 0.5 g to 1.5 g per week.

16 . The method of 12 , wherein the titration step (b) comprises administering descending doses of the sodium oxybate.

17 . The method of claim 16 , wherein dose is decreased by about 0.5 g to 9.0 g per week.

18 . The method of claim 12 , wherein the titration step (b) comprises switching a patient from a once a day dose to a twice a day dose of the sodium oxybate.

19 . The method of claim 12 , wherein the titration step (b) comprises switching a patient from a twice a day dose to a three times a day, or a once a day dose of the sodium oxybate.

20 . The method of claim 2 , wherein about 0.25 g-10.0 g of the sodium oxybate is administered per day.

21 . The method of claim 4 , wherein the initial daily dose is 4.5 g of sodium oxybate, and the dose is titrated to 6 g to 9 g of sodium oxybate per night.

22 . The method of claim 4 , wherein the sodium oxybate is in a mixed salt oxybate.

23 . The method of claim 22 , wherein the mixed salt oxybate comprises sodium oxybate, calcium oxybate, potassium oxybate, and magnesium oxybate.

24 . The method of claim 23 , wherein the mixed salt oxybate comprises about 8% sodium oxybate, about 23% potassium oxybate, about 21% magnesium oxybate, and about 48% calcium oxybate (% mol. eq.).

25 . The method of claim 22 , wherein the initial daily dose is 3.0 g of mixed salt oxybate, and the dose is titrated to 4.5 g to 9 g of mixed salt oxybate per night.

26 . The method of claim 21 , wherein the sodium oxybate is provided in a solid formulation.

27 . The method of claim 21 , wherein the sodium oxybate is present in a sustained release oxybate composition.

28 . The method of claim 21 , wherein the sodium oxybate is administered once daily.

29 . The method of claim 22 , wherein the mixed oxybate is administered once daily or twice daily.
