Methods of treating pain
The invention relates to methods for treating pain disorders including neuropathic and inflammatory pain and to methods to reduce or eliminate nociceptive tolerance induced by opiate analgesic use by administering an agent that suppresses or blocks S1P biological activity.
1. A method of treating chemotherapy induced neuropathic pain in an individual, the method comprising administering to the individual an effective amount of a drug selected from S1P receptor agonists and S1P receptor antagonists.
2. The method of claim 1 , wherein the chemotherapy comprises the administration of a drug selected from the group consisting of taxanes, platinum compounds, vinca alkaloids, proteasome inhibitors, and combinations thereof.
3. The method of claim 2 , wherein the chemotherapy is selected from the group consisting of paclitaxel, oxaliplatin, bortezomib, vincristine, and combinations thereof.
4. The method of claim 1 , wherein the S1P receptor agonist is selected from the group consisting of Fingolimod, BAF312, Ponesimod, ONO-4641, CS-0777, KRP-203, PF-991, W146, and combinations thereof.
5. A method of treating opiate-induced pain-hypersensitivity in an individual, the method comprising administering to the individual an effective amount of a drug selected from S1P receptor agonists and S1P receptor antagonists.
6. The method of claim 5 , wherein the opiate-induced pain-hypersensitivity is induced by morphine.
7. The method of claim 5 , wherein the S1P receptor agonist is selected from the group consisting of Fingolimod, BAF312, Ponesimod, ONO-4641, CS-0777, KRP-203, PF-991, and W146.
