Abstract

Robust sustained release formulations, solid dosage forms comprising robust sustained release formulations, and methods for making and using these formulations and solid dosage forms are provided. Robustness of the sustained release formulation is related to the particle size of the hydrophilic gum. Sustained release formulations resist dose-dumping when ingested with alcohol. The formulations are useful for treating a patient suffering from a condition, e.g., pain. The formulations comprise at least one drug. In one embodiment, the drug is an opioid, e.g., oxymorphone.

Claims (45)

1 . A method of relieving pain comprising administering to a patient a sustained release oxymorphone formulation comprising a sustained release delivery system and from about 5 mg to about 80 mg of oxymorphone, wherein after oral administration of a single dose to the patient with about 200 mL to about 300 mL of about 4% to about 40% ethanol the formulation provides a secondary peak of blood oxymorphone concentration about 12 hours after administration, and the formulation provides analgesia to the patient for at least about 12 hours after administration.

2 . The method of claim 1 , wherein the sustained release oxymorphone formulation comprises from about 20 mg to about 60 mg of oxymorphone.

3 . The method of claim 2 , wherein the sustained release oxymorphone formulation comprises about 40 mg of oxymorphone.

4 . The method of any one of claims 1 , 2 or 3 , wherein the sustained release oxymorphone formulation is a solid dosage form.

5 . The method of claim 4 , wherein the solid dosage form is selected from the group consisting of a tablet, a capsule, a granule, and a powder.

6 . The method of claim 5 , wherein the solid dosage form is a tablet.

A method of relieving pain comprising administering to a patient a sustained release oxymorphone formulation comprising a sustained release delivery system and from about 5 mg to about 80 mg of oxymorphone, wherein after oral administration of a single dose to a patient the formulation provides a maximum blood concentration of oxymorphone less than about 5 times higher when ingested with about 200 mL to about 300 mL of up to about 40% ethanol compared to when ingested without ethanol, and the formulation provides analgesia to the patient for at least about 12 hours after administration.

8 . The method of claim 7 , wherein the maximum blood concentration of oxymorphone is less than about 2.5 times higher when ingested with about 200 mL to about 300 mL of up to about 40% ethanol compared to when ingested without ethanol.

9 . The method of claim 7 , wherein the sustained release oxymorphone formulation comprises from about 20 mg to about 60 mg of oxymorphone.

11 . A method of relieving pain comprising administering to a patient a sustained release oxymorphone formulation comprising a sustained release delivery system and from about 5 mg to about 80 mg of oxymorphone, wherein after oral administration of a single dose to a patient the formulation provides a ratio of the maximum blood concentration of oxymorphone when ingested with about 200 mL to about 300 mL of about 40% ethanol to the maximum blood concentration of oxymorphone when ingested after a high-fat meal without ethanol of about 0.5 to about 2, and the formulation provides analgesia to the patient for at least about 12 hours after administration.

12 . The method of claim 11 , wherein the ratio of the maximum blood concentration of oxymorphone when the formulation is ingested with about 200 mL to about 300 mL of about 40% ethanol to the maximum blood concentration of oxymorphone when the formulation is ingested after a high-fat meal without ethanol is from about 0.8 to about 1.5.

13 . The method of claim 11 , wherein the sustained release oxymorphone formulation comprises from about 20 mg to about 60 mg of oxymorphone.

14 . The method of claim 13 , wherein the sustained release oxymorphone formulation comprises about 40 mg of oxymorphone.

15 . A method of relieving pain comprising administering to a patient a sustained release oxymorphone formulation comprising a sustained release delivery system and from about 5 mg to about 80 mg of oxymorphone, wherein after oral administration of a single dose to a patient with about 200 mL to about 300 mL of about 4% to about 40% ethanol the formulation provides a maximum blood concentration of oxymorphone from about 0.1 ng/mL to about 15 ng/mL, and the formulation provides analgesia to the patient for at least about 12 hours after administration.

16 . The method of claim 15 , wherein the sustained release oxymorphone formulation provides a maximum blood concentration of oxymorphone from about 0.5 ng/mL to about 7.5 ng/mL.

17 . The method of claim 16 , wherein the sustained release oxymorphone formulation provides a maximum blood concentration of oxymorphone from about 1 ng/mL to about 4 ng/mL.

18 . The method of claim 15 , wherein the sustained release oxymorphone formulation comprises from about 10 mg to about 20 mg of oxymorphone and the formulation provides a maximum blood concentration of oxymorphone from about 0.3 ng/mL to about 3.2 ng/mL.

19 . The method of claim 18 , wherein the formulation provides a maximum blood concentration of oxymorphone from about 0.4 ng/mL to about 2.8 ng/mL.

20 . The method of claim 18 , wherein the formulation comprises about 10 mg of oxymorphone and the formulation provides a maximum blood concentration of oxymorphone from about 0.3 ng/mL to about 1.8 ng/mL.

21 . The method of claim 20 , wherein the formulation provides a maximum blood concentration of oxymorphone from about 0.5 ng/mL to about 1.5 ng/mL.
