A nose drop containing the compound (I) represented by the formula
wherein Ar1 and Ar2 are each an aromatic group, Ar1 and Ar2 optionally form a condensed cyclic group together with the adjacent carbon atom, ring B is a nitrogen-containing heterocycle, X and Y are each a bond, an oxygen atom or S(O)p (p is 0 to 2), NR4 (R4 is H or a lower alkyl group) or a divalent linear lower hydrocarbon group optionally having substituents and containing 1 to 3 heteroatoms, A is N or CR7 (R7 is H, a halogen atom, a hydrocarbon group, an acyl group or a hydroxy group optionally having substituents), R1, R2 and R3 are each H, a halogen atom, a hydrocarbon group, an acyl group or a hydroxy group optionally having substituents, and
R8 is H, a hydroxy group optionally substituted by a lower alkyl group or a carboxyl group, provided that the nitrogen-containing heterocycle represented by ring B is not a heterocycle represented by the formula
wherein n is 0 - 1, or a salt thereof or a prodrug thereof, exhibits a superior prophylactic or therapeutic effect on allergic rhinitis and the like.
