Abstract

The invention relates to a tamper-resistant tablet comprising

• • (i) a matrix material in an amount of more than one third of the total weight of the tablet; and
  • (ii) a plurality of particulates in an amount of less than two thirds of the total weight of the tablet; wherein said particulates comprise a pharmacologically active compound and a polyalkylene oxide; and form a discontinuous phase within the matrix material;
    and method of using said tablet to treat pain and other conditions.

Claims

1. A tamper-resistant tablet comprising

(i) a matrix material in an amount of more than one third of the total weight of the tablet;

and

(ii) a plurality of particulates in an amount of less than two thirds of the total weight of the tablet;

wherein said particulates comprise a pharmacologically active compound and a polyalkylene oxide; and

form a discontinuous phase within the matrix material.

2. The tablet according to claim 1, which provides under in vitro conditions immediate release of the pharmacologically active compound in accordance with Ph. Eur.

3. The tablet according to claim 2, which has under in vitro conditions a disintegration time measured in accordance with Ph. Eur. of at most 3 minutes.

4. The tablet according to claim 1, wherein the content of the matrix material is at least 40 wt.-%, based on the total weight of the tablet.

5. The tablet according to claim 1, wherein the pharmacologically active compound is an opioid.

6. The tablet according to claim 1, wherein the particulates have an average diameter of about 1000±

250 μ

m and/or an average length of about 750±

250 μ

m.

7. The tablet according to claim 1, wherein the pharmacologically active compound is dispersed in the polyalkylene oxide.

8. The tablet according to claim 1, wherein the content of the polyalkylene oxide is at least 25 wt.-%, based on the total weight of a particulate.

9. The tablet according to claim 1, wherein the content of the pharmacologically active compound is at least 25 wt.-%, based on the total weight of a particulate.

10. The tablet according to claim 1, wherein the particulates are hot melt-extruded.

11. The tablet according to claim 1, wherein the particulates are film coated.

12. The tablet according to claim 1, wherein the matrix material is also present in particulate form.

13. The tablet according to claim 1, wherein the matrix material is dry granulated or compacted.

14. The tablet according to claim 1, wherein the matrix material comprises binder, filler, disintegrant and/or lubricant.

15. The tablet according to claim 14, wherein the disintegrant is crosslinked.

16. A method of treating a condition in a patient in need thereof by administering to a patient in need of such treating a tablet comprising an effective amount therefor of a pharmacologically active compound, wherein the tablet is a tablet according to claim 1.

17. The method according to claim 16, wherein the condition is pain.

18. The method according to claim 17, wherein the pharmacologically active compound is an opioid.
