Title:Sodium nitrite-containing pharmaceutical compositions
Abstract: Provided herein are pharmaceutically acceptable sodium nitrite and pharmaceutical compositions thereof. Also provided herein are methods for determining the total non-volatile organic carbon in a sodium nitrite-containing sample. Further provided herein are methods for producing pharmaceutically acceptable sodium nitrite. Still further provided herein are methods of treatment comprising the administration of pharmaceutically acceptable sodium nitrite.
Inventor(s): Sherman; Craig (Scottsdale, AZ), Lepine; Anthony James (Greendale, WI), Smith; Catherine Marie (Grafton, WI), Wirtz; Kevin Robert (Belgium, WI), Schulze; Erich (Mission Viejo, CA)
Assignee: Hope Medical Enterprises, Inc. (Scottsdale, AZ)
Filing Date:Oct 01, 2013
Application Number:14/042,783
Claims:1. A method for treating a cardiovascular disease with a decrease in blood flow comprising administering to a subject having a cardiovascular disease a therapeutically effective amount of sodium nitrite which contains no greater than about 0.02% by weight of sodium carbonate, contains no greater than about 10 ppm of an anti-caking agent, has a loss on drying of no greater than about 0.25% by weight, wherein the water content is no greater than about 0.5% by weight, wherein the heavy metal content is no greater than about 10 ppm, contains no greater than about 0.4% by weight of sodium nitrate, contains no greater than about 0.005% by weight of insoluble matter, contains no greater than about 0.005% by weight of chloride, contains no greater than about 0.01% by weight of sulfate, contains no greater than about 0.001% by weight of iron, contains no greater than about 0.01% by weight of calcium, contains no greater than about 0.005% by weight of potassium, contains no greater than about 0.05 ppm of mercury, contains no greater than about 2 ppm of aluminum, contains no greater than about 3 ppm of arsenic, contains no greater than about 0.003% by weight of selenium, contains no greater than about 5000 ppm of ethanol, contains no greater than about 3000 ppm methanol, wherein the total non-volatile organic carbon content is no greater than about 10 ppm, and contains no greater than about 0.25 EU/mg of bacterial endotoxins.

2. The method of claim 1, wherein the sodium nitrite contains no less than about 97% by weight and no greater than about 101% by weight of sodium nitrite.

3. The method of claim 1, wherein the sodium nitrite contains no less than about 98% by weight of sodium nitrite.

4. The method of claim 1, wherein the sodium nitrite contains no less than about 99.8% by weight of sodium nitrite as measured by Ion Chromatography analysis.

5. The method of claim 1, wherein the sodium nitrite is a white to off-white solid.

6. The method of claim 1, wherein a 10% aqueous solution of the sodium nitrite at 25.degree. C. has a pH value between about 8 and about 9.

7. The method of claim 1, wherein the sodium nitrite has total aerobic count of microbial load of no greater than about 100 CFU/g and has total yeast and mold count of no greater than about 20 CFU/g.

8. The method of claim 1, wherein the cardiovascular disease is cerebral vasospasm.

9. The method of claim 1, wherein the cardiovascular disease is an ischemic central nervous system event.

10. The method of claim 1, wherein the cardiovascular disease is ischemia-reperfusion injury.

11. The method of claim 1, wherein the cardiovascular disease is angina.

12. The method of claim 1, wherein the cardiovascular disease is systemic hypertension.

13. The method of claim 1, wherein the cardiovascular disease is claudication.

14. The method of claim 1, wherein the cardiovascular disease is high blood pressure.

15. The method of claim 1, wherein the cardiovascular disease is peripheral artery disease.

16. The method of claim 1, wherein the cardiovascular disease is critical limb ischemia.

17. The method of claim 1, wherein the cardiovascular disease is tissue ischemia-reperfusion injury.

18. The method of claim 1, wherein the cardiovascular disease is pulmonary hypertension.

19. The method of claim 1, wherein the cardiovascular disease is cutaneous ulceration.
