The invention provides methods and compositions for treatment of pain, such as joint pain, using capsaicin in a procedure that attenuates transient burning sensation experienced by patients due to capsaicin administration. The methods desirably provide relief from joint pain, such as osteoarthritic knee joint pain, for an extended duration, such as at least about 3 months, 6 months, 9 months, or 1 year. To attenuate the adverse side effect of a transient burning sensation caused by capsaicin-induced neuronal excitation, the methods utilize a cooling article, such as a material wrap cooled via a circulating fluid, to reduce the temperature of tissue to be exposed to capsaicin to within a certain range for certain durations of time, optionally in combination with administering a local anesthetic agent, resulting in the substantial reduction or even elimination of transient burning sensation caused by capsaicin.
本发明提供了使用辣椒素治疗疼痛(如关节疼痛)的方法和组合物,其治疗过程可减轻患者因服用辣椒素而产生的短暂灼烧感。这些方法最好能在较长时间内缓解关节疼痛,例如骨关节炎膝关节疼痛,例如至少约3个月、6个月、9个月或1年。为了减轻由辣椒素诱导的神经元兴奋引起的瞬时烧灼感的不良副作用,这些方法利用冷却物品,例如通过循环流体冷却的材料包裹,将暴露于辣椒素的组织的温度降低到一定范围内,持续一定的时间,可选地与施用局部麻醉剂相结合,从而大大减轻甚至消除由辣椒素引起的瞬时烧灼感。
