What side effects are associated with this type of intervention?

Common side effects of anticholinergic agents like oxybutynin, which are used to treat overactive bladder by relaxing the bladder muscle, include dry mouth, constipation, blurred vision, dizziness, and urinary retention. Some patients may also experience cognitive side effects such as confusion or memory impairment, particularly in older adults. Topical formulations like oxybutynin gel may reduce the incidence of systemic side effects compared to oral forms, but local skin reactions such as itching or redness can occur.

What prior FDA approvals exist?

The FDA has approved several anticholinergic agents for the treatment of Overactive Bladder (OAB). These include oral oxybutynin, which is available in immediate-release and extended-release formulations, as well as transdermal patches and topical gels. Other anticholinergic drugs approved for OAB include tolterodine, solifenacin, darifenacin, fesoterodine, and trospium. These medications work by inhibiting the muscarinic receptors in the bladder, thereby reducing bladder muscle contractions and alleviating symptoms of urgency, frequency, and incontinence.

What other types of research exist?

Promising novel alternatives to Oxybutynin Chloride 10% Topical Gel for Overactive Bladder patients include: 1) Beta-3 adrenergic agonists like Mirabegron, which relax the bladder muscle by a different mechanism than anticholinergics. 2) Vibegron, another beta-3 adrenergic agonist, which has shown efficacy in recent studies. 3) Intravesical botulinum toxin injections, which can reduce bladder muscle overactivity. 4) Emerging neuromodulation techniques such as percutaneous tibial nerve stimulation (PTNS) and sacral neuromodulation (SNM), which modulate nerve signals to the bladder. These alternatives provide different mechanisms of action and may offer benefits in terms of efficacy and side effect profiles.

Summary

This trial tests a skin-applied gel medicine for children with bladder issues caused by nerve problems. The gel helps relax the bladder muscles to reduce overactivity. Children will use the gel for a few months, with doses adjusted based on their response.

Who is the study for?

This trial is for children aged 3 to less than 17 with an overactive bladder due to a neurogenic condition. They must be able to perform clean intermittent catheterization (CIC). Children cannot participate if they have sensitivity to anticholinergics, bladder augmentation, or anatomical bladder abnormalities.

What is being tested?

The study tests Oxybutynin Chloride 10% Topical Gel's safety and effectiveness in managing overactive bladders in children with neurogenic conditions. Treatment starts at 0.75 g of gel per day for two weeks, with possible dose adjustments after that based on response and tolerability for a total of 14 weeks.

What are the potential side effects?

Potential side effects may include dry mouth, constipation, headache, dizziness, blurred vision, and difficulty urinating. These are common side effects associated with anticholinergic medications like Oxybutynin.

Other Research

The most common treatments for Overactive Bladder (OAB) include anticholinergic agents like Oxybutynin Chloride. These medications work by blocking acetylcholine from binding to muscarinic receptors in the bladder muscle, which helps to relax the bladder and reduce involuntary contractions. This mechanism is important for OAB patients as it helps to manage symptoms such as frequent urination, urgency, and incontinence, ultimately improving their daily functioning and quality of life.
