## 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

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 1)

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

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

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

### Claim 12 (depends on 1)

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

### Claim 13 (depends on 12)

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

### Claim 14 (depends on 12)

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

### Claim 15 (depends on 12)

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.

### Claim 16 (depends on 12)

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