1
(wherein A represents, for example, phenyl group substituted by R
1
and R
2
, or an unsubstituted furyl group or an unsubstitued thienyl group; R
1
represents, for example, hydrogen atom, fluorine atom, chlorine atom, trifluoromethyl group, nitro group, cyano group or methyl group while R
2
represents, for example, hydrogen atom; R
3
represents, for example, hydrogen atom or methyl group; R
4
represents, for example, hydrogen atom or methyl group; R
5
represents ethoxy group or isopropoxy group; X represents group: —CH(OH)— or methylene group; and Z represents, for example, a single bond or methylene group unsubstituted or substituted by hydroxyl group), and its salts, and medicinal compositions containing, as their active ingredient, the above compound or its salts. The compound of this invention, which is orally applicable, is highly effective for treating neuroapthic pain while presenting with fewer side-effects than do the conventional analgesics.
