05/10/2012 Botox (onabotulinum toxin-A) treatments administered to the bladder are just as likely to tackle urinary urgency incontinence problems in women as medications, and are 2 times as effective in eliminating symptoms completely, according to a recent study conducted by Loyola University Chicago Stritch School of Medicine (SSOM) and other experts from the National Institutes of Health network.
This new report coincides with a 2011 trial, which suggested that botox had been approved to help urinary incontinence in patients with neurological conditions.
Urinary incontinence occurs when urine leaks involuntarily, and is almost always due to an underlying medical condition. Urgency incontinence is the same as urinary incontinence, but accompanied by an intense, out-of-the-blue need to use the bathroom. The most common reason for urgency urinary incontinence is when detrusor muscles contract spontaneously.
Parkinson's, Alzheimer's, multiple sclerosis, spina bifida, stroke and other injuries can all damage muscles and bladder nerves.
This condition has traditionally been treated by prescribing medications which weaken bladder contractions (anticholinergics). Anticholinergics affect the bladder muscle via the nervous system. The problem with these medications is that women often report constipation, dry mouth, dry eyes, and other side effects.
Roughly 15.7% of women suffer from urinary incontinence, and women have a two-fold likelihood over men of developing the annoying condition. Bladder problems have been linked to diabetes and obesity; women who suffer from lack of bladder control have a higher chance of developing depression. During the trial, the researchers examined 241 women suffering from urinary
urgency incontinence. Of these individuals, some were given six-months of oral
drugs to be taken daily in addition to a saline shot. The others were given one
shot of Botox (onabotulinum toxin-A), as well as a placebo pill to be taken every
day.
When the study commenced, the participants had, on average, 5
urgency incontinence occurrences every day. Over the course of 6 months, the
occurrences were reduced to 3.4 with the oral drugs and 3.3 with Botox
(onabotulinum toxin-A).
Urgency incontinence completely disappeared among
13% of women who were taking anticholinergics and 27% among those taking
onabotulinum toxin-A. Both groups of women showed a boost in quality of life.
In terms of side effects, 46% of patients in the anticholinergic group
reported dry mouth, compared to only 31% in the onabotulinum toxin-A group. Incomplete emptying of the bladder was reported more among the onabotulinum
group as well (5%), compared to 0% in the other group. Those who had incomplete
bladder emptying problems had to be treated with catheterization.
Dr.
Brubaker, continued: "These results will help doctors weigh treatment options
for women and make recommendations based on individual patient needs.
