The present invention provides a compound a piperidine derivative having excellent histamine receptor antagonistic action, which is useful as active ingredients of a pharmaceutical composition, especially an antihistamine. The piperidine derivative of the present invention has a potent histamine receptor antagonistic action. Further, the compound of the present invention shows low brain transfer even in a cerebral receptor binding test where a mouse is orally administered with the compound, so that the compound has preferred properties of alleviating side effects in the central nervous system, such as drowsiness. The piperidine derivative of the present invention is very useful as a novel antihistamine having smaller side effects in the central nervous system, such as drowsiness.
