Pharmaceutical composition for treatment or prevention of stress urinary incontinence or mixed urinary incontinence, and screening method for compounds contained in the pharmaceutical composition
The present invention provides a pharmaceutical composition for treating or preventing urinary incontinence based on a novel mechanism of action, and a method for screening a compound contained as an active ingredient in the pharmaceutical composition. The present invention relates to a pharmaceutical composition for treating or preventing stress urinary incontinence or mixed urinary incontinence, which contains a compound having a melatonin receptor activating action as an active ingredient. Examples of the active ingredient include melatonin, ramelteon, agomelatin, tasimelteon, TIK-301 and the like. Also effective for pharmaceutical composition for treatment or prevention of stress urinary incontinence or mixed urinary incontinence comprising the steps of measuring activation of melatonin receptor, measuring contraction of isolated urethra, measuring urethral pressure, etc. The present invention relates to a method for screening a compound contained as a component.
