Methods for treating cerebrovascular disease by administering desmethylselegiline
The present disclosure is directed to methods for reducing the neuronal damage associated with cerebrovascular disease, such as stroke or cerebral edema, by administering R(−)-desmethylselegiline, S(+) desmethylselegiline, or a combination of the two. The cerebrovascular disease may be caused by ischemia or hypoxia.
1 . A method for the treatment of stroke in a subject in need of such treatment comprising:
administering R(−)-desmethylselegiline to the subject in an amount sufficient to limit, reduce or eliminate neuronal damage associated with the stroke.
2 . The method of claim 1 , wherein the stroke is ischemic stroke.
3 . The method of claim 1 , wherein the stroke is a transient ischemic attack.
4 . The method of claim 1 , wherein the stroke is an intracranial hemorrhage.
5 . The method of claim 4 , wherein the intracranial hemorrhage is a parenchymatous hemorrhage or a subarachnoid hemorrhage.
6 . The method of claim 4 , wherein the intracranial hemorrhage is caused by an aneurysm.
7 . The method of claim 6 , wherein the aneurysm is a saccular aneurysm.
8 . The method of claim 1 , wherein the stroke is caused by a drug, fibromuscular dysplasia, arterial dissection, homocystinuria, migraine, or emboli.
9 . The method of claim 1 , further comprising administering a therapeutic agent useful in the treatment of stroke in conjunction with R(−)-desmethylselegiline.
10 . The method of claim 9 , wherein the therapeutic agent is selected from the group consisting of tissue plasminogen activator, aspirin, and heparin.
11 . The method of claim 1 , wherein the subject is a human.
12 . The method of claim 1 , wherein the R(−)-desmethylselegiline is administered orally.
13 . The method of claim 1 , wherein the R(−)-desmethylselegiline is administered by a route that avoids absorption of R(−)-desmethylselegiline from the gastrointestinal tract.
14 . The method of claim 13 , wherein the R(−)-desmethylselegiline is administered intravenously, transdermally, buccally, sublingually, or parenterally.
15 . The method of claim 1 , wherein the R(−)-desmethylselegiline is administered at a dose of between 0.01 mg/kg per day and 0.15 mg/kg per day.
16 . A method for the treatment of cerebral edema in a subject in need of such treatment, comprising:
administering R(−)-desmethylselegiline to the subject in an amount sufficient to limit, reduce or eliminate neuronal damage associated with the cerebral edema.
17 . The method of claim 16 , wherein the cerebral edema is intracellular edema.
18 . The method of claim 16 , wherein the cerebral edema is interstitial edema.
19 . The method of claim 16 , wherein the subject is a human.
20 . The method of claim 16 , wherein the R(−)-desmethylselegiline is administered orally.
21 . The method of claim 16 , wherein the R(−)-desmethylselegiline is administered by a route that avoids absorption of R(−)-desmethylselegiline from the gastrointestinal tract.
22 . The method of claim 21 , wherein the R(−)-desmethylselegiline is administered intravenously, transdermally, buccally, sublingually, or parenterally.
23 . The method of claim 16 , wherein the R(−)-desmethylselegiline is administered at a dose of between 0.01 mg/kg per day and 0.15 mg/kg per day.
24 . A method for the treatment of cerebrovascular disease in a subject in need of such treatment, comprising:
administering R(−)-desmethylselegiline to the subject in an amount sufficient to limit, reduce or eliminate neuronal damage associated with the cerebrovascular disease.
25 . The method of claim 24 , wherein the cerebrovascular disease is selected from the group consisting of stroke, intracranial hemorrhage, occlusive hemorrhage, cerebral hemorrhage, subarachnoid hemorrhage, hemorrhagic lesion, subderal hematoma, aneurysm, and cerebral abscess.
26 . The method of claim 24 , wherein the cerebrovascular disease is caused by cerebral ischemia.
27 . The method of claim 26 , wherein the cerebral ischemia causes selective ischemic necrosis or cerebral infarction.
28 . The method of claim 24 , wherein the cerebrovascular disease is caused by cerebral hypoxia.
29 . The method of claim 24 , wherein the cerebrovascular disease is caused by traumatic brain injury, atherosclerosis, vasculitide, or arrhythmia.
30 . The method of claim 29 , wherein the arrhythmia is atrial fibrillation.
31 . The method of claim 24 , wherein the subject is a human.
32 . The method of claim 24 , wherein the R(−)-desmethylselegiline is administered orally.
33 . The method of claim 24 , further comprising administering a therapeutic agent useful in the treatment of cerebrovascular disease in conjunction with R(−)-desmethylselegiline to the subject.
34 . The method of claim 33 , wherein the therapeutic agent is selected from the group consisting of tissue plasminogen activator, aspirin, heparin, heparinoids, ticlopidine, clopidogrel, warfarin, glutamate receptor antagonists, nimodipine, phenylephrine, and dopamine.
35 . The method of claim 24 , wherein the R(−)-desmethylselegiline is administered by a route that avoids absorption of R(−)-desmethylselegiline from the gastrointestinal tract.
36 . The method of claim 35 , wherein the R(−)-desmethylselegiline is administered intravenously, transdermally, buccally, sublingually, or parenterally.
37 . The method of claim 24 , wherein the R(−)-desmethylselegiline is administered at a dose of between about 0.01 mg/kg per day and about 0.15 mg/kg per day.
