Abstract

The present invention comprises a co-processed carbohydrate system, and formulations produced therefrom, which formulations are directly compressible into solid dosage forms, some of which rapidly and completely dissolve or disintegrate in the oral cavity within 60 seconds. The invention also comprises the solid dosage forms produced by directly compressing the co-processed carbohydrate system, some of which, when placed in the oral cavity, shall dissolve or disintegrate, preferably within about 60 seconds.

Claims (34)

1. A method for producing a directly compressible quick-dissolving composition, said method comprising:

a) dissolving mannitol powder and sorbitol powder into a solution;

b) dry feeding a blend of dry mannitol powder and dry sorbitol powder in the same proportion as the mannitol and sorbitol in the solution of step (a), into a spray drying chamber;

c) drying the mixture in an air stream;

d) forming particles having a nonfilamentous microstructure from the mixture; and

e) diluting the resulting particles with a disintegrant, thereby forming a directly compressible quick-dissolving composition.

2. The composition of claim 1 , further comprising a glidant.

3. The composition of claim 1 , wherein said disintegrant is selected from the group consisting of crospovidone, croscarmellose, sodium starch glycolate, and combinations thereof.

4. The composition of claim 2 , wherein said glidant is selected from group consisting of colloidal silica, silica gel, precipitated silica, and combinations thereof.

5. The composition of claim 1 , wherein said mannitol is present in a range of 60 to 99.5 percent and wherein said sorbitol is present in a range of 0.5 to 40 percent.

6. The composition of claim 5 , wherein said mannitol is present in a range of 70 to 95 percent and wherein said sorbitol is present in a range of 5 to 30 percent.

7. The composition of claim 6 , wherein said mannitol is present in a range of 80 to 90 percent and wherein said sorbitol is present in a range of 10 to 20 percent.

8. The composition of claim 1 , further comprising an active ingredient.

9. The composition of claim 8 , wherein said active ingredient is coated.

10. The composition of claim 8 , wherein said active ingredient is uncoated.

11. The composition of claim 1 , said composition being directly compressible.

12. A tablet comprising the composition of claim 1 .

13. A quick-dissolving composition prepared by the method of claim 1 , said composition comprising:

(a) particles including co-spray dried mannitol and sorbitol;

(b) a disintegrant selected from the group consisting of crospovidone, croscarmellose, sodium starch glycolate, and combinations thereof;

(c) a glidant selected from the group consisting of silica gel, and colloidal silica, precipitated silica, and combinations thereof; and

(d) an active ingredient.

14. A quick-dissolving composition prepared by the method of claim 1 , wherein the composition comprising co-spray-dried mannitol and sorbitol, and a disintegrant, and wherein said composition is highly compatible and dissolves in the oral cavity in less than 60 seconds.

15. The composition of claim 14 , further comprising a glidant.

16. The composition of claim 14 , wherein said disintegrant is selected from the group consisting of crospovidone, croscarmellose, sodium starch glycolate, and combinations thereof.

17. The composition of claim 15 , wherein said glidant is selected from group consisting of colloidal silica, silica gel, precipitated silica, and combinations thereof.

18. The composition of claim 14 , wherein said mannitol is present in a range of 60 to 99.5 percent and wherein said sorbitol is present in a range of 0.5 to 40 percent.

19. The composition of claim 18 , wherein said mannitol is present in a range of 70 to 95 percent and wherein said sorbitol is present in a range of 5 to 30 percent.

20. The composition of claim 19 , wherein said mannitol is present in a range of 80 to 90 percent and wherein said sorbitol is present in a range of 10 to 20 percent.

21. The composition of claim 14 , further comprising an active ingredient.

22. The composition of claim 21 , wherein said active ingredient is coated.

23. The composition of claim 21 , wherein said active ingredient is uncoated.

24. The composition of claim 14 , wherein said composition is directly compressible.

25. A tablet comprising the composition of claim 14 .
