标题 :Compositions and methods of treatment of sympathetically maintained pain
发明人：CAMPBELL JAMES N
权利人:ARCLON THERAPEUTICS INC
摘要:Sympathetically maintained pain is treated topically by administering to the site where sympathetically maintained pain is present an α-1-adrenergic antagonist, α-2-adrenergic agonist, or other drug that depletes or blocks synthesis of sympathetic norepinephrine, known collectively as sympatholytic agents. Chemical formulas for several sympatholytic agents are given.
