A piperidine derivative of the formula (I) is found to bind specifically with the NR1/NR2B receptor and usable as an analgesic (pain treatment drug).
wherein X is OH or lower alkylsufonyloxy; Ar is optionally substituted aryl or optionally substituted heteroaryl; n is an integer of 1 to 4; m is an integer of 0 to 1; R1 is hydrogen; R2 is OH or R1 and R2 taken together may form a single bond; excluding that
1) n is 2; m is 0; R1 and R2 taken together may form a single bond; and Ar is optionally substituted phenyl and
2) n is 3; m is 0; R1 and R2 taken together may form a single bond; and Ar is phenyl.
