REMEDY FOR HYPERACTIVE BLADDER

摘要

The present invention provides a therapeutic agent for overactive bladder, which has both a K ATP channel opening action and a nitrate-like action and is further expected to produce an ameliorating effect for ensuring a reflexive and suitable cooperation between contraction-relaxation of abdominal/bladder wall muscle and relaxation-contraction movement of urethral sphincter during urination and urine storage, so that the therapeutic agent does not induce oliguria or urinary retention and has no serious side effect. Nicorandil or a pharmaceutically acceptable salt thereof is used as an active ingredient.
