Title:Oxycodone hydrochloride having less than 25 ppm 14-hydroxycodeinone
Abstract:In certain embodiments the invention is directed to a process for preparing an oxycodone hydrochloride composition having less than 25 ppm of 14-hydroxycodeinone.
Inventor(s): Chapman; Robert (North Kingstown, RI), Rider; Lonn S. (Foster, RI), Hong; Qi (Sharon, MA), Kyle; Donald (Newtown, PA), Kupper; Robert (Coventry, RI)
Assignee: Purdue Pharma L.P. (Stamford, CT)
Application Number:11/653,531
Patent Claims: 1. An oral dosage form comprising particles, the particles comprising from about 5 mg to about 320 mg oxycodone hydrochloride active pharmaceutical ingredient having less than 25 ppm 14-hydroxycodeinone, wherein at least a portion of the 14-hydroxycodeinone is derived from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone during conversion of oxycodone free base to oxycodone hydrochloride, said particles being coated with an amount of hydrophobic material effective to provide a sustained release of the oxycodone hydrochloride when the coated particles are exposed to an aqueous solution.

2. An oral dosage form comprising (i) from about 5 mg to about 320 mg of oxycodone hydrochloride active pharmaceutical ingredient having less than 25 ppm 14-hydroxycodeinone, wherein at least a portion of the 14-hydroxycodeinone is derived from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone during conversion of oxycodone free base to oxycodone hydrochloride; and (ii) a sustained release material, wherein the sustained release material is film coated onto said oxycodone hydrochloride active pharmaceutical ingredient.

3. An oral dosage form comprising: (i) from about 5 mg to about 320 mg of oxycodone hydrochloride active pharmaceutical ingredient having less than 25 ppm 14-hydroxycodeinone, wherein at least a portion of the 14-hydroxycodeinone is derived from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone during conversion of oxycodone free base to oxycodone hydrochloride; and (ii) a pharmaceutically acceptable excipient.

4. The oral dosage form of claim 1, wherein the 14-hydroxycodeinone is derived solely from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone.

5. The oral dosage form of claim 2, wherein the 14-hydroxycodeinone is derived solely from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone.

6. The oral dosage form of claim 3, wherein the oxycodone hydrochloride active pharmaceutical ingredient has a lower limit of the 14-hydroxycodeinone of 0.25 ppm, 0.5 ppm, 1 ppm, 2 ppm or 5 ppm.

7. The oral dosage form of claim 3, wherein the 14-hydroxycodeinone is derived solely from 8.alpha.,14-dihydroxy-7,8-dihydrocodeinone.

8. The oral dosage form of claim 1, wherein the oxycodone hydrochloride active pharmaceutical ingredient has a lower limit of the 14-hydroxycodeinone of 0.25 ppm, 0.5 ppm, 1 ppm, 2 ppm or 5 ppm.

9. The oral dosage form of claim 2, wherein the oxycodone hydrochloride active pharmaceutical ingredient has a lower limit of the 14-hydroxycodeinone is of 0.25 ppm, 0.5 ppm, 1 ppm, 2 ppm or 5 ppm.

10. The oral dosage form of claim 8, which is a tablet or a capsule.

11. The oral dosage form of claim 8 comprising about 5 mg, about 10 mg, about 15 mg, about 20 mg, about 30 mg, about 40 mg, about 50 mg, about 60 mg, about 80 mg, about 100 mg, about 160 mg or about 320 mg of the oxycodone hydrochloride active pharmaceutical ingredient.

12. The oral dosage form of claim 8, comprising 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80 mg or 160 mg of the oxycodone hydrochloride active pharmaceutical ingredient.

13. The oral dosage form of claim 9, which is a tablet or a capsule.

14. The oral dosage form of claim 9 comprising about 5 mg, about 10 mg, about 15 mg, about 20 mg, about 30 mg, about 40 mg, about 50 mg, about 60 mg, about 80 mg, about 100 mg, about 160 mg or about 320 mg of the oxycodone hydrochloride active pharmaceutical ingredient.

15. The oral dosage form of claim 9 comprising 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80 mg or 160 mg of the oxycodone hydrochloride active pharmaceutical ingredient.

16. The oral dosage form of claim 6, which is a tablet or a capsule.

17. The oral dosage form of claim 6 comprising about 5 mg, about 10 mg, about 15 mg, about 20 mg, about 30 mg, about 40 mg, about 50 mg, about 60 mg, about 80 mg, about 100 mg, about 160 mg or about 320 mg of the oxycodone hydrochloride active pharmaceutical ingredient.

18. The oral dosage form of claim 6 comprising 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80 mg or 160 mg of the oxycodone hydrochloride active pharmaceutical ingredient.
