Time course of IT baclofen effect on reflex responses to UBD. Graphs depict the rapid onset and duration of inhibitory effect of a single 40 ng dose of IT baclofen or IT normal saline on repeated pressor (A) and viscero-motor (B) responses evoked by a urinary bladder distension (60 mm Hg, 20 s, every 3 min) normalized as percentage of pre-drug responses.
