Mirabegron is the first β3-adrenoceptor agonist that is clinically effective for overactive bladder. The effects of mirabegron on primary bladder mechanosensitive single-unit afferent activities (SAAs) and bladder microcontractions were evaluated and compared with the effects of oxybutynin. Female Sprague-Dawley rats...
