Methods of treating idiopathic hypersomnia
The present disclosure relates to methods of treating idiopathic hypersomnia with oxybate, preferably a mixture of salts of oxybate (a mixed salt oxybate).
1. A method of treating idiopathic hypersomnia in a patient in need thereof, the method comprising:
a twice daily dosing regimen, comprising (a) administering to an adult patient with idiopathic hypersomnia an initial daily dose of less than or equal to about 4.5 grams of a mixed salt oxybate divided equally or unequally into 2 doses; and (b) titrating the daily dose to provide a therapeutically effective amount of the mixed salt oxybate, wherein the maximum daily dose is about 9 grams divided equally or unequally into 2 doses; or
a once daily dosing regimen, comprising (a) administering to an adult patient with idiopathic hypersomnia an initial daily dose of less than or equal to about 3 grams of the mixed salt oxybate; and (b) titrating the daily dose to provide a therapeutically effective amount of the mixed salt oxybate, wherein the maximum daily dose is about 6 grams;
wherein the mixed salt oxybate comprises about 5%-40% sodium oxybate, about 10%-40% potassium oxybate, about 5%-30% magnesium oxybate, and about 20%-80% of calcium oxybate (% mol. eq.).
2. The method of claim 1 , 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.).
3. The method of claim 1 , wherein the initial daily dose is from about 0.5 g to about 4.5 g of the mixed salt oxybate.
4. The method of claim 1 , wherein the initial daily dose is about 4.5 g of the mixed salt oxybate.
5. The method of claim 1 , wherein the titration step (b) comprises administering ascending doses of the mixed salt oxybate.
6. The method of claim 5 , wherein the dose is increased by about 0.5 g to 1.5 g per night per week.
7. The method of claim 1 , wherein the titration step (b) is from about 1 week to about 10 weeks.
8. The method of claim 1 , wherein about 4.5 g of the mixed salt oxybate is administered per day.
9. The method of claim 1 , wherein about 6 g of the mixed salt oxybate is administered per day.
10. The method of claim 9 , wherein about 3 g of the mixed salt oxybate is administered twice per day.
11. The method of claim 1 , wherein about 7.5 g of the mixed salt oxybate is administered per day.
12. The method of claim 11 , wherein about 3.75 g of the mixed salt oxybate is administered twice per day.
13. The method of claim 1 , wherein about 9 g of the mixed salt oxybate is administered per day.
14. The method of claim 13 , wherein about 4.5 g of the mixed salt oxybate is administered twice per day.
15. The method of claim 1 , wherein the mixed salt oxybate is administered at bedtime and about 2 h-4 h after the bedtime administration.
16. The method of claim 1 , wherein about 4.5 g-6.0 g of the mixed salt oxybate is administered once per day.
17. The method of claim 1 , wherein the patient is administered the mixed salt oxybate at least 2 h after the patient's last meal.
18. The method of claim 1 , wherein about 3 g to about 6 g is administered per day.
19. The method of claim 1 , wherein the patient is an adult patient.
20. A method of treating idiopathic hypersomnia in a patient in need thereof, the method comprising:
a twice daily dosing regimen, comprising (a) administering to an adult patient with idiopathic hypersomnia an initial daily dose of less than or equal to about 4.5 grams of a mixed salt oxybate divided equally or unequally into 2 doses; and (b) titrating the daily dose to provide a therapeutically effective amount of the mixed salt oxybate, wherein the maximum daily dose is about 9 grams divided equally or unequally into 2 doses;
wherein the mixed salt oxybate comprises about 5%-40% sodium oxybate, about 10%-40% potassium oxybate, about 5%-30% magnesium oxybate, and about 20%-80% of calcium oxybate (% mol. eq.).
21. The method of claim 20 , wherein the titration step (b) comprises administering ascending doses of no more than about 1.5 grams/night per week of the mixed salt oxybate.
22. A method of treating idiopathic hypersomnia in a patient in need thereof, the method comprising:
a once daily dosing regimen, comprising (a) administering to an adult patient with idiopathic hypersomnia an initial daily dose of less than or equal to about 3 grams of a mixed salt oxybate; and (b) titrating the daily dose to provide a therapeutically effective amount of the mixed salt oxybate, wherein the maximum daily dose is about 6 grams;
wherein the mixed salt oxybate comprises about 5%-40% sodium oxybate, about 10%-40% potassium oxybate, about 5%-30% magnesium oxybate, and about 20%-80% of calcium oxybate (% mol. eq.).
23. The method of claim 22 , wherein the titration step (b) comprises administering ascending doses of no more than about 1.5 grams/night per week of the mixed salt oxybate.
