Treatment of autistic spectrum disorder
View Patent ↗A method for treating a patient having ASD is disclosed. The method includes administering to the patient a therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form in combination with a therapeutically effective amount of inositol.
1. A method for treating a patient having core symptoms of Autism Spectrum Disorder (“ASD”) comprising administering to the patient a therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form in combination with a therapeutically effective amount of inositol, wherein the therapeutically effective amount of inositol is from about 9,000 mg to about 32,400 mg per day and wherein the method treats the patient's core symptoms of ASD.
2. The method of claim 1 , wherein the patient has core symptoms of ASD and at least one associated ASD symptom selected from the group consisting of: impulsivity, concentration deficit or attention deficit and emotional lability/irritability.
3. The method of claim 1 , wherein the patient has associated ASD symptom of emotional lability/irritability, the therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form in combination with the therapeutically effective amount of inositol being effective to reduce the emotional lability/irritability.
4. The method of claim 1 , wherein the therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form in combination with the therapeutically effective amount of inositol has a greater effect in addressing part A of the DSM 5.0 definition of ASD in the patient than either administration of the alpha-2 adrenergic agonist in the absence of the inositol or administration of the inositol in the absence of the alpha-2 adrenergic agonist.
5. The method of claim 4 , wherein the greater effect is at least additive.
6. The method of claim 4 , wherein the greater effect is greater than additive.
7. The method of claim 4 , wherein the greater effect is measured according to the Social Responsiveness Scale.
8. The method of claim 1 , wherein the alpha-2 adrenergic agonist is selected from the group consisting of clonidine and guanfacine.
9. The method of claim 1 , wherein the therapeutically effective amount of inositol is from about 12,000 mg to about 32,400 mg per day.
10. The method of claim 1 , wherein the therapeutically effective amount of inositol for a patient is a maximum effective dose for the patient, the maximum effective dose being immediately below an amount that induces diarrhea in the patient.
11. The method of claim 10 , wherein the maximum effective dose is within 10% of the amount of inositol that induces diarrhea in the patient.
12. The method of claim 1 , wherein the therapeutically effective amount of inositol is given in twice daily administrations.
13. The method of claim 1 , wherein the therapeutically effective amount of inositol is given in three times daily administrations.
14. The method of claim 1 , wherein the alpha-2 adrenergic agonist is clonidine and the therapeutically effective amount of clonidine is from about 0.0125 mg to about 0.60 mg per day.
15. The method of claim 14 , wherein the therapeutically effective amount of clonidine is from about 0.10 mg to about 0.60 mg per day.
16. The method of claim 1 , wherein the alpha-2 adrenergic agonist is guanfacine and the therapeutically effective amount of guanfacine is from about 0.125 mg to about 4 mg per day.
17. The method of claim 1 , wherein the alpha-2 adrenergic agonist is in a dosage form selected from the group consisting of: a solid oral dosage form, liquid oral dosage form, and a transdermal patch; and wherein the inositol is in a dosage form selected from the group consisting of: tablets, capsules, powder, and a liquid oral dosage form.
18. A method for reducing at least one core Autism Spectrum Disorder (“ASD”) symptom and at least one associated ASD symptom in a patient having ASD, the method comprising administering to the patient a therapeutically effective amount of an alpha-2 adrenergic agonist in an extended release dosage form and a therapeutically effective amount of inositol, wherein the therapeutically effective amount of inositol is from about 9,000 mg to about 32,400 mg per day and wherein the method treats the patient's at least one core ASD symptom and the patient's at least one associated ASD symptom.
19. The method of claim 18 , wherein the at least one core ASD symptom is selected from the group consisting of: part A of the DSM 5.0 definition of ASD and part B of the DSM 5.0 definition of ASD, and wherein the at least one associated ASD symptom is selected from the group consisting of: impulsivity, concentration deficit or attention deficit, and emotional lability/irritability.
20. The method of claim 18 , wherein the alpha-2 adrenergic agonist is selected from the group consisting of clonidine and guanfacine.
21. The method of claim 18 , wherein the therapeutically effective amount of inositol is from about 12,000 mg to about 32,400 mg per day.
22. The method of claim 18 , wherein the therapeutically effective amount of inositol for a patient is a maximum effective dose for the patient, the maximum effective dose being immediately below an amount that induces diarrhea in the patient.
23. The method of claim 22 , wherein the maximum effective dose is within 10% of the amount of inositol that induces diarrhea in the patient.
24. The method of claim 18 , wherein the therapeutically effective amount of inositol is given in twice daily administrations.
25. The method of claim 18 , wherein the therapeutically effective amount of inositol is given in three times daily administrations.
26. The method of claim 18 , wherein the therapeutically effective amount of an alpha-2 adrenergic agonist in extended release dosage form in combination with the therapeutically effective amount of inositol has a greater effect in reducing the at least one core ASD symptom and/or the at least one associated ASD symptom in the patient than either administration of the alpha-2 adrenergic agonist in the absence of the inositol or administration of the inositol in the absence of the alpha-2 adrenergic agonist.
27. The method of claim 26 , wherein the greater effect is at least additive.
28. The method of claim 26 , wherein the greater effect is greater than additive.
