Baclofen and acamprosate based therapy of neurological disorders
The present invention relates to combinations and methods for the treatment of neurological disorders related to glutamate excitotoxicity and Amyloid β toxicity. More specifically, the present invention relates to novel combinatorial therapies of Multiple Sclerosis, Alzheimer's disease, Alzheimer's disease related disorder, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, neuropathic pain, alcoholic neuropathy, alcoholism or alcohol withdrawal, or spinal cord injury, based on Baclofen and Acamprosate combination.
1. A method of treating Alzheimer's disease or a related disease selected from senile dementia of AD type (SDAT), mild cognitive impairment (MCI) and age-associated memory impairment (AAMI), comprising administering to a subject in need thereof a synergistic combination of baclofen and acamprosate, or pharmaceutically acceptable salts thereof, in an amount effective to treat said subject.
2. The method of claim 1 , wherein baclofen and acamprosate are mixed with a pharmaceutically acceptable carrier or excipient.
3. The method of claim 1 , wherein baclofen and acamprosate are formulated or administered together, separately or sequentially.
4. The method of claim 1 , wherein baclofen and acamprosate are administered repeatedly to the subject.
5. The method of claim 1 , wherein the synergistic combination of baclofen and acamprosate has a ratio of Acamprosate/Baclofen (W:W) between 0.1 and 1000.
6. The method of claim 1 , wherein baclofen is administered at a dose of between 0.01 and 150 mg/day.
7. The method of claim 1 , wherein acamprosate is administered at a dose of less than 400 mg/day.
8. The method of claim 1 , wherein a calcium salt of acamprosate is used.
9. The method of claim 1 , comprising administering to the subject:
baclofen and acamprosate,
baclofen and acamprosate and diethylcarbamazine,
baclofen and acamprosate and cinacalcet,
baclofen and acamprosate and sulfisoxazole,
baclofen and acamprosate and torasemide,
baclofen and acamprosate and ifenprodil,
baclofen and acamprosate and mexiletine,
baclofen and acamprosate and eplerenone,
baclofen and acamprosate and levosimendan,
baclofen and acamprosate and terbinafine, or
baclofen and acamprosate and leflunomide.
10. The method of claim 1 , comprising administering to a subject a composition comprising:
baclofen, acamprosate and donepezil,
baclofen, acamprosate and rivastigmine, or
baclofen, acamprosate and memantine.
11. The method of claim 1 , comprising administering to the subject baclofen and acamprosate as the only active agents.
12. A method for improving cognitive functions in a subject suffering from, predisposed to, or suspected to suffer from Alzheimer's disease, the method comprising administering to said subject a synergistic combination of baclofen and acamprosate, or pharmaceutically acceptable salts thereof in an amount effective to treat said subject.
13. A method for improving memory in a subject suffering from, predisposed to, or suspected to suffer from Alzheimer's disease, the method comprising administering to said subject a synergistic combination of baclofen and acamprosate, or pharmaceutically acceptable salts thereof in an amount effective to treat said subject.
14. The method of claim 1 , wherein baclofen and acamprosate act synergistically in protecting neuronal or endothelial cells from Aβ toxicity in vitro.
15. The method of claim 1 , wherein the subject is a human subject.
16. The method of claim 1 , wherein said subject is a human subject having Alzheimer's disease.
17. The method of claim 1 , said method comprising administering 0.01 to 150 mg/day of baclofen, or pharmaceutically acceptable salts thereof, and less than 400 mg/day of acamprosate, or pharmaceutically acceptable salts thereof, as the synergistic combination of baclofen and acamprosate to said subject.
