Detrusor Overactivity
Detrusor overactivity happens when the bladder muscle contracts involuntarily before the bladder is full. The result is a sudden, intense urge to urinate that can be difficult to suppress, and sometimes leads to leakage. It is one of the most common reasons behind overactive bladder syndrome and affects a significant number of adults across South and Southeast Asia.
Medicine used to treat Detrusor Overactivity
What drives the bladder muscle to fire early
The detrusor muscle is normally held in check by nerve signals from the brain and spinal cord. When those signals are disrupted, the muscle contracts without warning. Causes range from neurological conditions such as multiple sclerosis or stroke, to local bladder irritation from infection, ageing, or unknown origin (idiopathic). In many cases no single trigger is found.
Anticholinergic medicines are the mainstay of treatment. They work by blocking the nerve signals that trigger involuntary contractions. Oxybutynin is the most established option and forms part of the bladder health treatment landscape. Bladder training, timed voiding, and reducing bladder irritants such as caffeine and alcohol can complement medication.
