Abstract

Disclosed herein are methods, pharmaceutical combinations, or kits for the prevention or treatment of extrapyramidal syndromes, for example, dyskinesia, dystonia, akathisia, or drug-induced Parkinsonism, with the administration of a therapeutic effective amount of Trapidil, a derivative, a metabolite, a prodrug, an analog, or a pharmaceutically acceptable salt thereof.

Claims

1. A combination therapy method for treating Parkinson'"'"'s disease in a subject in need thereof, comprising administering to the subject a therapeutically effective combination of:

Trapidil, a derivative, a metabolite, or a pharmaceutically acceptable salt thereof; and

levodopa;

thereby treating Parkinson'"'"'s disease in the subject;

wherein the derivative of Trapidil is

2. The method of claim 1, wherein Trapidil is N,N-diethyl-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine.

3. The method of claim 1, wherein levodopa is formulated with a decarboxylase inhibitor.

4. The method of claim 3, wherein the decarboxylase inhibitor is comprised of carbidopa or benserazide.

5. The method of claim 1, wherein the pharmaceutically acceptable salt of Trapidil comprises a salt with hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, nitric acid, oxalic acid, malonic acid, or tartaric acid.

6. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof and levodopa are administered simultaneously, sequentially, or at an interval period of time.

7. The method of claim 6, wherein if sequentially, Trapidil or a pharmaceutically acceptable salt thereof is administered prior to administration of levodopa.

8. The method of claim 6, wherein if sequentially, Trapidil or a pharmaceutically acceptable salt thereof is administered after the administration of levodopa.

9. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof and levodopa are administered as a combined dosage form.

10. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof and levodopa are each independently formulated for oral administration.

11. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof and levodopa are each independently formulated for parenteral administration.

12. The method of claim 1, wherein the subject is diagnosed with the Parkinson'"'"'s disease.

13. The method of claim 1, wherein the combination therapy delays onset of a movement disorder associated with the Parkinson'"'"'s disease in the subject.

14. The method of claim 13, wherein the movement disorder is manifested as a dyskinesia, dystonia, akathisia, bradykinesia, tremors, or akinesia.

15. The method of claim 13, wherein the movement disorder is dyskinesia and the preventing is a delay in onset of dyskinesia or a slowing down of the progression of dyskinesia.

16. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof decreases the dose of levodopa administered to the subject relative to a dose of levodopa administered to the same subject in the absence of Trapidil or a pharmaceutically acceptable salt thereof.

17. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof potentiate the effect of levodopa.

18. The method of claim 1, wherein Trapidil or a pharmaceutically acceptable salt thereof is used as an adjunctive or adjuvant therapeutic agent.

19. The method of claim 1, wherein the subject is a human.

20. The method of claim 1, wherein the therapeutically effective combination does not cause levodopa-induced dyskinesia in the subject.
