Abstract

A solid administration form, protected from parenteral abuse and containing at least one viscosity-increasing agent in addition to one or more active substances that have parenteral abuse potential. The agent forms, when a necessary minimum amount of an aqueous liquid is added, on the basis of an extract obtained from the administration form, a preferably injectable gel that remains visually distinct when introduced into another quantity of an aqueous liquid.

Claims

1. A solid dosage form for oral administration with reduced potential for parenteral abuse, said dosage form comprising:

(a) one or more active ingredients having potential for abuse selected from the group consisting of hydrocodone, morphine, oxycodone, tramadol, tapentadol, and pharmaceutically acceptable salts and solvates thereof; and

(b) one or more viscosity-increasing agents in a quantity such that an aqueous extract of a total content of the dosage form when comminuted and combined with 10 ml of water at 25°

C. forms a gel that can be drawn up into and injected back out of a hypodermic needle having a diameter of 0.9 mm, into a further quantity of water, wherein threads of the gel injected from said needle remain visible to the naked eye in said further quantity of water at 37°

C.

2. The dosage form according to claim 1, wherein the active ingredient is oxycodone or a salt or solvate thereof.

3. The dosage form according to claim 1, wherein the active ingredient is hydrocodone or a salt or solvate thereof.

4. The dosage form according to claim 1, wherein the active ingredient is morphine or a salt or solvate thereof.

5. The dosage form according to claim 1, wherein the one or more viscosity-increasing agents are selected from the group consisting of microcrystalline cellulose with 11 wt. % carboxymethylcellulose sodium, carboxymethylcellulose sodium, polyacrylic acid, locust bean flour, citrus pectin, waxy maize starch, sodium alginate, guar flour, iota-carrageenan, karaya gum, gellan gum, galactomannan, tara stone flour, propylene glycol alginate, apple pectin, lemon peel pectin, sodium hyaluronate, tragacanth, tara gum, fermented polysaccharide welan gum and xanthan gum.

6. The dosage form according to claim 1, in particulate form.

7. The dosage form according to claim 1, comprising at least one active ingredient in controlled release form.

8. The dosage form according to claim 1, comprising a coating resistant to gastric juices.

9. The dosage form according to claim 1, in multiparticulate form, wherein said multiparticulate form is in the form of microtablets, microcapsules, micropellets, granules, spheroids, beads or pellets, packaged in capsules or press-molded into tablets.

10. The dosage form according to claim 1, wherein said threads remain visible to the naked eye in said further quantity of water for at least one minute.

11. The dosage form according to claim 1, wherein said threads remain visible to the naked eye in said further quantity of water for at least ten minutes.

12. The dosage form according to claim 1, which further comprises microcrystalline cellulose.

13. The dosage form according to claim 1, which further comprises hydroxypropylmethylcellulose.

14. A solid dosage form for oral administration with reduced potential for parenteral abuse, said dosage form comprising:

(a) one or more active ingredients with potential for abuse selected from the group consisting of hydrocodone, morphine, oxycodone, tramadol, tapentadol, and pharmaceutically acceptable salts and/or solvates thereof; and

(b) one or more viscosity-increasing agents in a quantity such that an aqueous extract of a total content of the dosage form when comminuted and combined with 10 ml of water at 25°

C. forms an injectable gel that can be drawn up into and injected back out of a syringe having a diameter of 0.9 mm, but wherein the injectable gel cannot be safely injected from said syringe into blood vessels of an abuser because the presence of the injectable gel in the abuser'"'"'s blood vessels would obstruct one or more of said abuser'"'"'s blood vessels.

15. The dosage form according to claim 14, wherein the active ingredient is oxycodone or a salt or solvate thereof.

16. The dosage form according to claim 14, wherein the active ingredient is hydrocodone or a salt or solvate thereof.

17. The dosage form according to claim 14, wherein the active ingredient is morphine or a salt or solvate thereof.

18. The dosage form according to claim 14, which further comprises microcrystalline cellulose.

19. The dosage form according to claim 14, which further comprises hydroxypropylmethylcellulose.

20. The dosage form according to claim 14, comprising at least one active ingredient in controlled release form.
