Abstract

There is provided a fast dissolving solid dosage form adapted for the release of a biologically active material in the oral cavity wherein the dosage form comprises at least one biologically active material, and at least one matrix forming agent, wherein the dosage form substantially dissolves in the oral cavity. A method of producing the same and a kit comprising the same are also provided.

Claims (22)

1. A fast disintegrating and dissolving freeze-dried wafer solid dosage form with a porous matrix for release of a biologically active material in an oral cavity wherein said dosage form comprises:

(a) a biologically active material at a concentration from 0.02 to 95 weight % by dry weight of the dosage form; and

(b) amylopectin at a concentration from 2% to 17% by dry weight of the dosage form wherein the amylopectin is not in the form of starch or modified starch; and

(c) a carbohydrate chosen from the list consisting of: mannitol, dextrose, lactose, galactose and trehalose at a concentration from 5% to 80% by dry weight of the dosage form,

wherein the powder x-ray diffraction (XRD) of the dosage form comprises peaks at 2-theta values at approximately 9.58 degrees, 19.68 degrees, and 20.05 degrees;

wherein said dosage form disintegrates in the oral cavity;

wherein said biologically active material is absorbed by diffusion directly into the systemic circulation.

2. The dosage form of claim 1 wherein the biologically active material is an anti-inflammatory agent.

3. The dosage form of claim 1 wherein the biologically active material is a complementary medicine.

4. The dosage form according to claim 1 , further comprising glycine present in an amount from 0.5 to 5 weight % by dry weight of the dosage form.

5. The dosage form of claim 1 , wherein the dosage form further comprises sodium carboxymethyl cellulose (CMC) present in an amount from 0.1 to 15% dry weight of the dosage form.

6. The dosage form according to claim 1 , wherein the dosage form dissolves once placed in the oral cavity in a time period selected from the group consisting of: less than 50 seconds, less than 40 seconds, less than 30 seconds, less than 20 seconds, less than 15 seconds, less than 10 seconds, less than 7.5 seconds, less than 5 seconds, less than 4 seconds, less than 3 seconds, and less than 2 seconds.

7. A kit comprising a fast disintegrating and dissolving freeze-dried wafer solid dosage form with a porous matrix for release of a biologically active material in an oral cavity, wherein the dosage form comprises:

a) a biologically active material at a concentration from 0.02 to 95 weight % by dry weight of the dosage form; and

b) amylopectin at a concentration from 2% to 17% by dry weight of the dosage form wherein the amylopectin is not in the form of starch or modified starch; and

c) a carbohydrate chosen from the list consisting of: mannitol, dextrose, lactose, galactose and trehalose at a concentration from 5% to 80% by dry weight of the dosage form,

wherein the powder x-ray diffraction (XRD) of the dosage form comprises peaks at 2-theta values at approximately 9.58 degrees, 19.68 degrees, and 20.05 degrees;

wherein said dosage form disintegrates in the oral cavity; and

wherein said biologically active material is absorbed by diffusion directly into the systemic circulation.

8. The kit according to claim 7 , further comprising instructions for its use.

9. The kit according to claim 7 , wherein the biologically active material is an anti-inflammatory agent.

10. The kit according to claim 7 , wherein the biologically active material is a complementary medicine.
