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 (23)

1. A quick-dissolving composition comprising:

particles comprising co-spray-dried polyols including mannitol and sorbitol, wherein said particles have a crystalline and nonfilamentous microstructure on a surface of the particles; and

a disintegrant,

wherein said composition dissolves in the oral cavity in less than 60 seconds.

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 co-spray-dried polyols comprise mannitol in a range of 60 to 99.5 percent and sorbitol in a range of 0.5 to 40 percent.

6. The composition of claim 5 , wherein said co-spray-dried polyols comprise mannitol in a range of 70 to 95 percent and sorbitol in a range of 5 to 30 percent.

7. The composition of claim 6 , wherein said co-spray-dried polyols comprise mannitol in a range of 80 to 90 percent and sorbitol 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 , wherein said composition is directly compressible.

12. A tablet comprising the composition of claim 1 .

13. A composition comprising particles including co-spray-dried mannitol and sorbitol, wherein said particles have a nonfilamentous microstructure on a surface of the particles, and said composition is highly compactible.

14. The composition of claim 13 , further comprising a disintegrant.

15. The composition of claim 13 , 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 13 , wherein said co-spray-dried mannitol and sorbitol comprises mannitol in a range of 60 to 99.5 percent and sorbitol in a range of 0.5 to 40 percent.

19. The composition of claim 18 , wherein said co-spray-dried mannitol and sorbitol comprises mannitol in a range of 70 to 95 percent and sorbitol in a range of 5 to 30 percent.

20. The composition of claim 19 , wherein said co-spray-dried mannitol and sorbitol comprises mannitol in a range of 80 to 90 percent and sorbitol in a range of 10 to 20 percent.
