8. The method of claim 1 , wherein the pain is inflammatory pain.
9. The method of claim 1 , wherein the pain is neuropathic pain.
10. The method of claim 1 , wherein the pharmaceutical composition, further comprises:
at least one additional active agent selected from the group consisting of:
an inhibitor of protein kinase A (PKA), an inhibitor of cAMP signaling, a nonsteroidal anti-inflammatory drug, a prostaglandin synthesis inhibitor, an anticonvulsant, an antidepressant, an opioid receptor agonist, a neuroleptic, an agonist of GABA A receptor, an analgesic or anti-cancer agent that acts by a mechanism different from a TrkA antagonist, a benzodiazepine, a barbiturate, a neurosteroid, an anesthetic, an anticancer drug, a modulator of mGluR5 receptor, and a combination thereof
11. The method of claim 10 , wherein the anesthetic is a local anesthetic or an inhalation anesthetic.
12. The method of claim 1 , wherein the pharmaceutical composition is formulated in a unit dosage form selected from the group consisting of:
