Abstract

Described herein are orodispersible films comprising a film forming hydrophobic polymer, a disintegrant, a plasticizer and a stabilizer.

Claims (30)

1. An orodispersible film comprising (i) a film forming polymer, wherein the film forming polymer is polyvinyl acetate, wherein the concentration of the polyvinyl acetate in the orodispersible film is between 30% and 95% by weight; (ii) a disintegrant; and (iii) polyvinyl alcohol (PVA) or hydroxypropylmethyl cellulose (HPMC).

2. The orodispersible film of claim 1 , wherein the disintegrant is (i) a cellulose derivative, (ii) a cellulose ether, (iii) carboxymethylcellulose or a salt thereof, or (iv) sodium carboxymethylcellulose.

3. The orodispersible film of claim 1 further comprising one or more dispersants.

4. The orodispersible film of claim 3 , wherein the one or more dispersants comprise one or more of (i) sodium lauryl sulfate, (ii) povidone, (iii) macrogol cetostearyl ether, and (iv) sorbic acid and sodium hydroxide.

5. The orodispersible film of any one of claims 1 and 3 further comprising a plasticizer.

6. The orodispersible film of claim 5 , wherein the plasticizer is (i) a citrate derivative, (ii) triethylcitrate, (iii) glycerol, (iv) polyethylene glycol, or (v) propylene glycol.

7. The orodispersible film of claim 1 , wherein the concentration of at least one of the polyvinyl alcohol or hydroxypropylmethyl cellulose in the orodispersible film is between 5% and 17.5% by weight.

8. The orodispersible film of claim 1 further comprising one or more of (i) one or more sweeteners, (ii) one or more colorants, (iii) one or more flavoring agents, and (iv) one or more saliva stimulants.

9. The orodispersible film of claim 1 , wherein:

the concentration of the polyvinyl alcohol or hydroxypropylmethyl cellulose, in the orodispersible film, is between 1% and 21% by weight; and

the disintegrant is sodium carboxymethylcellulose, wherein the concentration of the sodium carboxymethylcellulose in the orodispersible film is between 1% and 22%; by weight

wherein the total percentage by weight of all the components of the orodispersible film does not exceed 100%.

10. The orodispersible film of claim 9 , wherein the concentration of the polyvinyl acetate in the orodispersible film is between 30% and 60% by weight.

11. The orodispersible film of claim 10 , wherein the concentration of the polyvinyl alcohol or hydroxypropylmethyl cellulose, in the orodispersible film, is between 5% and 17.5% by weight.

12. The orodispersible film of claim 11 further comprising a plasticizer.

13. The orodispersible film of claim 1 further comprising an active agent that is a pharmaceutical agent, a nutraceutical agent, a supplement, or a cosmetic agent.

14. A method of delivering an orodispersible film of claim 1 comprising placing the orodispersible film into the oral cavity for a sufficient period of time to disintegrate.

15. The orodispersible film of claim 1 , wherein the disintegration time of the orodispersible film upon contacting oral mucosa is less than or equal to 90 seconds.

16. The orodispersible film of claim 1 , wherein the disintegration time of the orodispersible film upon contacting oral mucosa is less than or equal to 45 seconds.

17. The orodispersible film of claim 1 , wherein the concentration of the polyvinyl acetate in the orodispersible film is between 30% and 60% by weight.

18. The orodispersible film of claim 1 , wherein the concentration of the disintegrant in the orodispersible film is between 1% and 22% by weight.

19. The orodispersible film of claim 1 , wherein the concentration of the disintegrant in the orodispersible film is between 5% and 17.5% by weight.

20. The orodispersible film of claim 1 , wherein the concentration of at least one of the polyvinyl alcohol or hydroxypropylmethylcellulose in the orodispersible film is between 1% and 21% by weight.

21. The orodispersible film of claim 1 , wherein the concentration of at least one of the polyvinyl alcohol or hydroxypropylmethylcellulose in the orodispersible film is between 5% and 17.5% by weight.

22. The orodispersible film of claim 3 , wherein the concentration of the one or more dispersants in the orodispersible film is between 0.001% and 10% by weight.

23. The orodispersible film of claim 5 , wherein the concentration of the plasticizer in the orodispersible film is between 1% and 20% by weight.

24. The orodispersible film of claim 1 , wherein the polyvinyl alcohol or hydroxypropylmethylcellulose is polyvinyl alcohol.

25. The orodispersible film of claim 1 , wherein the polyvinyl alcohol or hydroxypropylmethylcellulose is hydroxypropylmethylcellulose.

26. The orodispersible film of claim 1 , wherein the ratio of: (1) the concentration of polyvinyl acetate in the orodispersible film to (2) the concentration of the polyvinyl alcohol or hydroxypropylmethyl cellulose, in the orodispersible film, is between 20:1 and 1:2, by weight.

27. The orodispersible film of claim 9 further comprising an active agent that is a pharmaceutical agent, a nutraceutical agent, a supplement, or a cosmetic agent.
