A pyrazolopyridine derivative represented by the following formula (I) or a pharmacologically acceptable salt thereof exhibits a strong EP 1 receptor antagonistic effect. Thus, the derivative or the pharmacologically acceptable salt is useful as a therapeutic agent for lower urinary tract symptoms (LUTS), particularly, overactive bladder syndrome (OABs), or a prophylactic agent therefor and furthermore, is also useful in the treatment, prevention, or suppression of various pathological conditions in which the EP 1 receptor is involved, such as inflammatory disease, pain disease, osteoporosis, and cancer. n n n n n n n n n n [A is a benzene ring or the like, Y 1 is C 1-6 alkylene, R 1 is —C(═O)—OZ 1 or the like, Z 1 is H or the like, R 2 is a branched C 3-6 alkyl group or the like, R 3 is H or the like, R 4 is a hydrogen atom or the like, and R 5 is a hydrogen atom or the like]. |
