Title:	Non-aqueous liquid nimodipine compositions
Abstract:	Non-aqueous liquid compositions comprising nimodipine having improved stability over aqueous compositions comprising nimodipine are provided herein. Methods of improving neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured intracranial berry aneurysms with the non-aqueous liquid compositions of the present invention are also detailed herein.
Inventor(s):	Thomas; Hugh Greg (Carrollton, GA)
Assignee:	Arbor Pharmaceuticals, LLC (Atlanta, GA)
Application Number:	16/407,980
Patent Claims:	1. A non-aqueous liquid composition consisting essentially of (i) nimodipine as the only active ingredient and (ii) polyethylene glycol or a mixture of polyethylene glycol and one or more solvents selected from the group consisting of ethanol, isopropanol, butanol and glycerin, wherein about 5% or less nimodipine degradation is observed over a period of at least three months when exposed to 40.degree. C. and 75% relative humidity. 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.degree. 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.degree. 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.
