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 (55)

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;

(b) amylopectin at a concentration from 2% to 17% by dry weight of the dosage form;

(c) sodium carboxymethyl cellulose (CMC) at a concentration from 0.1 to 15% dry weight of the dosage form; and

(d) a carbohydrate chosen from a 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; and

wherein said dosage form disintegrates in the oral cavity in a time of less than 15 seconds and dissolves in the oral cavity in a time of less than 60 seconds without leaving a residue of said dosage form in the oral cavity that is detectable by a subject, thereby avoiding the urge for the subject to swallow the dosage form;

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

wherein the amylopectin is not in the form of starch or modified starch.

2. The dosage form according to claim 1 , wherein the biologically active material is present in an amount from 0.02 to 95 weight % by dry weight of the composition of the dosage form.

3. The dosage form according to claim 1 , further comprising glycine.

4. The dosage form according to claim 3 , wherein glycine is present in an amount from 0.5 to 5 weight % by dry weight of the dosage form.

5. The dosage form according to claim 1 , comprising mannitol.

6. The dosage form according to claim 5 , wherein mannitol is present in an amount from 5 to 80 weight % by dry weight of the dosage form.

7. The dosage form according to claim 1 , further comprising a lubricant.

8. The dosage form according to claim 7 , wherein the lubricant comprises polyethylene glycol (PEG) 2000.

9. The dosage form according to claim 8 , wherein PEG 2000 is present in an amount from 0.05 to 5 weight % by dry weight of the dosage form.

10. The dosage form according to claim 1 , further comprising a buffer reagent.

11. The dosage form according to claim 10 , wherein the buffer reagent comprises sodium carbonate.

12. The dosage form according to claim 11 , wherein sodium carbonate is present in an amount from 0.01 to 10 weight % by dry weight of the dosage form.

13. The dosage form according to claim 1 , further comprising an absorption enhancer.

14. The dosage form according to claim 13 , wherein the absorption enhancer comprises β-cyclodextrin.

15. The dosage form according to claim 14 , wherein β-cyclodextrin is present in an amount from 0.01 to 10 weight % by dry weight of the dosage form.

16. The dosage form according to claim 1 , further comprising a flocculating agent.

17. The dosage form according to claim 1 , further comprising a surfactant.

18. The dosage form according to claim 1 , further comprising an additive.

19. The dosage form according to claim 1 , further comprising a coloring agent.

20. The dosage form according to claim 19 , wherein the coloring agent is selected from the group consisting of FD&C dyes Blue No. 2, Red No. 40, and mixture therein.

21. The dosage form according to claim 1 , further comprising a flavoring agent.

22. The dosage form according to claim 21 , wherein the flavoring agent is selected from the group consisting of orange, mint, raspberry, caramel, aspartame, saccharin, and mixture therein.

23. 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.

24. The dosage form according to claim 1 , further comprising at least one pharmaceutically acceptable carrier.

25. 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;

(b) amylopectin at a concentration from 2% to 17% by dry weight of the dosage form;

(c) sodium carboxymethyl cellulose (CMC) at a concentration from 0.1 to 15% dry weight of the dosage form; and

(d) a carbohydrate chosen from a 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 the dosage form dissolves in the oral cavity without leaving a residue of said dosage form in the oral cavity that is detectable by a subject, thereby avoiding the urge for the subject to swallow the dosage form;

wherein said dosage form disintegrates in the oral cavity in a time of less than 15 seconds and dissolves in the oral cavity in a time of less than 60 seconds;

wherein said dosage form is absorbed by diffusion directly into the systemic circulation;

wherein the amylopectin is not in the form of starch or modified starch; and

wherein the solid dosage form is not a film.

26. The kit according to claim 25 , further comprising instructions for its use.

27. The dosage form of claim 1 , wherein the dosage form does not contain modified starch.

28. The kit of claim 25 , wherein the dosage form does not contain modified starch.

29. A freeze-dried wafer 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;

(b) a matrix forming agent comprising amylopectin at a concentration from 2% to 17% by dry weight of the dosage form;

(c) sodium carboxymethyl cellulose (CMC) at a concentration from 0.1 to 15% dry weight of the dosage form; and

(d) a carbohydrate chosen from a 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 in a time of less than 15 seconds and dissolves in the oral cavity in a time of less than 60 seconds without leaving a residue of said dosage form in the oral cavity that is detectable by a subject;
