Abstract

A composition and method of providing nitric oxide and nitrite therapy to patients whereby a therapeutic amount is bioavailable within approximately 30 minutes of administration. In embodiments of the invention, nitric oxide is produced in the oral cavity.

Claims

1. A delivery system comprising:

at least one nitric oxide-producing component; and

a dispersable medium adapted to be consumed in the oral cavity;

wherein the nitric oxide-producing component is adapted to generate nitric oxide in vivo upon consumption of the dispersable medium.

2. The delivery system of claim 1, wherein the dispersable medium is dissolvable in the oral cavity.

3. The delivery system of claim 1, wherein the dispersable medium is dissolvable in about five minutes or less.

4. The delivery system of claim 1, wherein the delivery system is adapted to generate nitric oxide in the oral cavity.

5. The delivery system of claim 1, where the nitric oxide-producing component is adapted to generate nitric oxide in-vivo in response to dissolution of the delivery system in the gastro intestinal tract.

6. The delivery system of claim 1, wherein the delivery system is formed of a lozenge, liquid, powder, solid, semi-solid, cream, gel, emulsion, suspension, heterogenic liquid, film, or topical.

7. The delivery system of claim 1, wherein the dispersable medium comprises one or more of a sugar, dispersing agent, flavor, sweetener, color, alcohol, maltodextren, or filler.

8. The delivery system of claim 1, wherein the nitric oxide-producing component is comprised of a nitrite, nitrate, or reductase or a combination of nitrite, nitrate and reductase.

9. The delivery system of claim 1 further comprising a barrier for preventing contact of two or more species of the nitric oxide-producing component.

10. The delivery system of claim 9, wherein the two or more species are nitrite and nitrite reductase.

11. The delivery system of claim 9, wherein the barrier comprises sugar, dispersing agent, flavors, sweetener, color, alcohol, maltodextren, or filler.

12. The delivery system of claim 1 further comprising a disintegrating agent, a compactible excipient, or both.

13. The delivery system of claim 12, wherein the disintegrating agent absorbs fluid upon contact with fluid.

14. The delivery system of claim 12, wherein the compactable excipient is adapted to maintain the delivery system in a compressed form.

15. The delivery system of claim 12, wherein the compactable excipient is chemically inert, does not absorb fluid, is non-hydroscopic, protects water-sensitive nitric oxide-producing components, does not react with nitric oxide-producing components and/or has a narrow particle size distribution.

16. The delivery system of claim 12 wherein the disintegrating agent causes the compactable excipient to break apart upon expansion.
