9. The method of claim 8, wherein the tablet comprises a 10 mg, 20 mg or 30 mg dose of stereomerically pure (+)-2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acetylaminoi- soindoline-1,3-dione.

10. The method of claim 9, wherein the tablet comprises a 10 mg dose of stereomerically pure (+)-2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acetylaminoi- soindoline-1,3-dione.

11. The method of claim 9, wherein the tablet comprises a 20 mg dose of stereomerically pure (+)-2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acetylaminoi- soindoline-1,3-dione.

12. The method of claim 9, wherein the tablet comprises a 30 mg dose of stereomerically pure (+)-2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acetylaminoi- soindoline-1,3-dione.

13. The method of claim 1, further comprising administering to the patient a therapeutically effective amount of one or more second active agents.

14. The method of claim 13, wherein the one or more second active agents are selected from the group consisting of a nonsteroidal anti-inflammatory drug, an immnunosuppressant, a topical steroid, a glucocorticoid, a calcineurin inhibitor, a Cox-2 inhibitor, a TNF-alpha inhibitor, an antirheumatic, an antipsoriatic, an interleukin inhibitor, a narcotic analgesic combination, a salicylate, a glucocorticoid and a topical rubefacient.

15. The method of claim 13, wherein the second active agent is a nonsteroidal anti-inflammatory agent.
