Abstract (en)

[origin: WO9214453A1] Sympathetically maintained pain is treated topically by administering to the site where sympathetically maintained pain is present an alpha -1-adrenergic antagonist, alpha -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.
