(-)-(9S)-9-(3-Bromo-4-fluorophenyl)-2,3,5,6,7,9-hexahydrothieno[3,2-b]quinolin-8(4H)-one 1,1-dioxide (A-278637): a novel ATP-sensitive potassium channel opener efficacious in suppressing urinary bladder contractions. II. in vivo characterization.
ATP-sensitive potassium (K(ATP)) channel openers (KCOs) have been shown to inhibit spontaneous myogenic contractile activity of the urinary bladder, a mechanism hypothesized to underlie detrusor instability and symptoms of overactive bladder. However, the therapeutic utility of KCOs has been limited by a lack of differentiation of bladder versus vascular… (More)
