Abstract: A method for treating a TRPV1-mediated disease by administering to a patient a therapeutically effective amount of a compound or a salt thereof having the following formula [I]: wherein A represents a lower alkylene group or a lower alkenylene group; R1 represents a hydrogen atom, an unsubstituted or substituted alkyl group or an unsubstituted or substituted alkenyl group; and R2 and R3 are the same or different and represent a hydrogen atom, an unsubstituted lower alkyl group or a lower alkyl group substituted by a monocyclic cycloalkyl group, a polycyclic cycloalkyl group or an aryl group.

Abstract: An object of the present invention is to find a novel pharmacological action of a urea compound having a structure represented by the general formula [I]. The urea compound having a structure represented by the general formula [I] or a salt thereof has an excellent therapeutic effect on a TRPV1-mediated disease. In the formula, A represents a lower alkylene group or a lower alkenylene group; R1 represents a hydrogen atom, an alkyl group which may have a substituent or an alkenyl group which may have a substituent; and R2 and R3 are the same or different and represent a hydrogen atom or a lower alkyl group which may be substituted by a monocyclic cycloalkyl group, a polycyclic cycloalkyl group, or an aryl group.
