2. The non-aqueous liquid composition of claim 1 , wherein the polyethylene glycol is selected from PEG 300 and PEG 400.
3. The non-aqueous liquid composition of claim 1 , wherein (ii) is a mixture of polyethylene glycol and glycerin.
4. The non-aqueous liquid composition of claim 1 , wherein (ii) is a mixture of polyethylene glycol, glycerin and isobutanol.
5. The non-aqueous liquid composition of claim 1 , wherein (ii) is a mixture of polyethylene glycol, glycerin and butanol.
6. The non-aqueous liquid composition of claim 1 , comprising from about 0.01% to about 1.5% nimodipine related compound A.
7. The non-aqueous liquid composition of claim 1 , wherein the concentration of nimodipine is from about 3 mg/mL to about 10 mg/mL.
8. The non-aqueous liquid composition of claim 1 , wherein the concentration of nimodipine is about 6 mg/mL.
9. The non-aqueous liquid composition of claim 1 , wherein the concentration of nimodipine is about 12 mg/mL.
10. The non-aqueous liquid composition of claim 1 , wherein nimodipine is present in an amount from about 10 mg to about 100 mg per dosage unit.
11. The non-aqueous liquid composition of claim 1 , wherein nimodipine is present in an amount of about 60 mg per dosage unit.
12. A method of improving neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms comprising administering to a patient in need thereof an effective amount of a non-aqueous liquid composition of claim 1 .
13. The method of claim 12 , wherein the composition is administered orally, via nasogastric tube or via gastric tube.
14. A non-aqueous liquid composition consisting essentially of (i) nimodipine as the only active ingredient and (ii) a mixture of polyethylene glycol and glycerin, wherein about 5% or less nimodipine degradation is observed over a period of at least three months when exposed to 40° C. and 75% relative humidity.
15. The non-aqueous liquid composition of claim 14 , comprising from about 0.01% to about 1.5% nimodipine related compound A.
16. The non-aqueous liquid composition of claim 14 , wherein the concentration of nimodipine is from about 3 mg/mL to about 10 mg/mL.
17. The non-aqueous liquid composition of claim 14 , wherein the concentration of nimodipine is about 6 mg/mL.
18. The non-aqueous liquid composition of claim 14 , wherein the concentration of nimodipine is about 12 mg/mL.
19. The non-aqueous liquid composition of claim 14 , wherein nimodipine is present in an amount from about 10 mg to about 100 mg per dosage unit.
20. The non-aqueous liquid composition of claim 14 , wherein nimodipine is present in an amount of about 60 mg per dosage unit.
21. A method of improving neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms comprising administering to a patient in need thereof an effective amount of a non-aqueous liquid composition of claim 14 .
22. The method of claim 21 , wherein the composition is administered orally, via nasogastric tube or via gastric tube.
23. A non-aqueous liquid composition consisting essentially of (i) nimodipine as the only active ingredient and (ii) a solvent selected from the group consisting of isopropanol, butanol, ethanol or a combination thereof, wherein about 5% or less nimodipine degradation is observed over a period of at least three months when exposed to 40° C. and 75% relative humidity.
24. A method of improving neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms comprising administering to a patient in need thereof an effective amount of a non-aqueous liquid composition of claim 23 .
