Abstract

The present invention relates to compositions and methods for the treatment of Alzheimer's disease and related disorders. More specifically, the present invention relates to novel combinatorial therapies of Alzheimer's disease and related disorders. In particular, the invention concerns compounds which, alone or in combination(s), can effectively modulate synapse function and/or angiogenesis and/or cell stress response. The invention also relates to methods of producing a drug or a drug combination for treating Alzheimer's disease and to methods of treating Alzheimer's disease or a related disorder.

First claim

The invention claimed is:

1. A method of treating Alzheimer's disease (AD) or an AD related disorder in a human in need thereof, the method comprising administering, per day, between 30 μg and 400 mg of carbamazine or a salt thereof or a sustained release formulation thereof to said human.

2. The method of claim 1 , wherein the effective amount is an amount that protects endothelial or neuronal cells against beta-amyloid (Abeta) peptide toxicity.

3. The method of claim 1 , further comprising administering to said human an effective amount of at least one additional compound selected from the group consisting of amlodipine, argatroban, cilostazol, cinacalcet, clopidogrel, dyphylline, fenoldopam, leflunomide, mepacrine, methimazole, phenformin, prilocaine, rifabutin, sulfisoxazole, tadalafil, terbinafine, cinnarizine, ciclopirox, eplerenone, carbenoxolone, sulodexide, amobarbital, cefotetan, erythrityl tetranitrate, methyclothiazide, risedronate, enprofylline, oxtriphylline, paramethadione, cefmenoxime, aprindine, etomidate, mitiglinide, benidipine, and zonisamide, salt(s) thereof and sustained release formulation(s) thereof, said additional compound being for combined, separate or sequential administration with carbamazine, the salt thereof or the sustained release formulation thereof.

4. The method of claim 3 , wherein said at least one additional compound is selected from sulfisoxazole or terbinafine, salt(s) thereof or sustained release formulation(s) thereof.

5. A method of treating Alzheimer's disease (AD) or an AD related disorder in a human in need thereof, the method consisting of combined, separate or sequential administration to said human of an effective amount of acamprosate, or a salt thereof or a sustained release formulation and between 30 μg and 400 mg per day of carbamazine or a salt thereof or a sustained release formulation thereof.

6. A method for protecting neuronal cells against Abeta peptide toxicity in a human having AD, consisting of combined, separate or sequential administration to the human of acamprosate, or a salt thereof or sustained release formulation thereof, and between 30 μg and 400 mg per day of carbamazine or a salt thereof or a sustained release formulation thereof.

7. The method of claim 1 , wherein carbamazine, the salt thereof or the sustained release formulation thereof, is administered with a pharmaceutically acceptable carrier or excipient.

8. The method of claim 1 , wherein carbamazine, the salt thereof or the sustained release formulation thereof, is administered repeatedly to the human.
