How Does Oxybutynin Work For Overactive Bladder

Must Read

Improved Efficacy With Ditropan And Tibial Neuromodulation Combination

Update on Oxytrol Transdermal Patch for Overactive Bladder

Our extensive experience at New York Urology Specialists and research studies both show that transcutaneous posterior tibial nerve stimulation and extended-release oxybutynin are both effective treatments for overactive bladder symptoms. The combination of these two therapies is associated with better results in terms of frequency of urination, urge incontinence, and urgency episodes.

There is also higher satisfaction with the combination treatment. Patients report fewer episodes of urinary incontinence and less bother from overactive bladder symptoms. In general, oxybutynin plus PTNS is associated with better control of urinary distress compared to either treatment alone.

Mixing Tolterodine With Herbal Remedies And Supplements

There might be a problem using herbal remedies and supplements while taking tolterodine.

Some herbal medicines can make you feel sleepy, cause a dry mouth, or make it difficult to pee. Their effect is similar to tolterodine. This can increase your risk of getting side effects or make your side effects worse.

Behavioral Modification For The Treatment Of Overactive Bladder

Various types of behavioral modifications may also be recommended for the treatment of overactive bladder. Examples include:

  • Dietary Changes: Decreasing water consumption throughout the day can help reduce leakage, as can avoiding substances that irritate the bladder, such as caffeine, fruit juices, and spicy foods.
  • Bladder Retraining: This method uses a set schedule for urination throughout the day. Between these times, no urination is allowed, even if leaks occur. The goal is to increase the time between bathroom visits to three to four hours.
  • Electrical Stimulation and Biofeedback: This technique provides information about when a patient is squeezing the muscles of her pelvic floor. A sensor is placed in the vagina or anus so that pelvic floor muscle contractions can be recorded. Exercises can help strengthen weak pelvic floor muscles, and if they don’t respond, electrical stimulation can activate the appropriate muscles.

Pharmacological Basis For Differential Cognitive Effects Of Antimuscarinic Drugs

Antimuscarinic agents interact with receptors throughout the body, including the M3 receptors of the bladder detrusor muscle, which are thought to be the primary target for antimuscarinic therapy in OAB . In the CNS, all five of the known muscarinic receptor subtypes are expressed . Although the role of each subtype in the brain has not yet been fully elucidated, interactions with M1, M2 and M4 muscarinic receptor subtypes have each been implicated in cognitive impairment . However, the muscarinic M1 receptor subtype, in particular, is thought to play a crucial role in modulating cognitive function . Evidence for a dominant role for the M1 receptor includes the severe impairment of working memory seen in M1 knockout mice and in animals administered intra-hippocampal injections of the M1 receptor antagonist pirenzepine , as well as the potential for muscarinic M1 agonist therapy to improve cognitive function in patients with dementia . By contrast, studies with M3 knockout mice have shown no impact on cognition or behaviour . Therefore, antimuscarinic therapy that is most selective for the M3 subtype combined with relative M1 sparing properties would be expected to have the lowest potential for adverse effects on cognition.

Pom Criterion 2 The Product Is Frequently And To A Very Wide Extent Used Incorrectly And As A Result Is Likely To Present A Direct Or Indirect Danger To Human Health

Oxybutynin Side Effects, How it Works, Upsides &  Downsides

The ways that Aquiette could be used incorrectly are:

  • Misuse/abuse

Risk of off-label use is discussed above.

Risk of misuse/abuse

The risk of abuse of anticholinergic medicines such as oxybutynin is considered low. This is particularly the case for Aquiette with the low strength of tablets intended for use as a pharmacy medicine. The adverse event section of the SmPC for Aquiette states dependence with frequency not known .

Safety in overdose

The risk of significant overdose with Aquiette is mitigated by the low strength tablets and maximum pack size of 30 tablets. An entire pack of 30 tablets represents 75 mg of oxybutynin.

The primary effects of oxybutynin in overdose are an exaggeration of the known adverse effects of the drug, based on the anticholinergic method of action. Other non-prescription medicines with anticholinergic action and diphenhydramine hydrochloride in cough/cold preparations) are available without prescription which would produce similar possible effects in overdose to oxybutynin. While a risk of overdose exists, this is not considered to be any greater than with the POM product.

Overall conclusion on POM criterion 2

The second POM criterion is not considered to be fulfilled for Aquiette because the risks of direct or indirect danger to human health from incorrect use, can be adequately managed through the product information and pharmacy training materials.

Dry mouth
Drink plenty of water to replace the lost fluids
Urine infections, skin irritation , feeling confused, dry eyes, flushing, difficulty passing urine If any become troublesome, please speak with your doctor

If you experience any other symptoms which you think may be due to oxybutynin, please speak with your doctor or pharmacist for further advice.

What Evidence Is Needed

A company or organisation can ask MHRA for a medicine to be available as a pharmacy medicine or a general sale medicine. To do this, they need to get together evidence to show that the medicine

a) is likely to be used appropriately, and

b) with relatively little danger to the public.

This evidence needs to focus on the risk to the public. This includes evidence on the possible abuse or misuse of the medicine. The evidence may include:

  • clinical studies
  • views of relevant health professionals and their professional bodies
  • views of relevant public associations and individuals with an interest in the medicine under consideration.

What Is The View Of The Commission On Human Medicines

The Commission on Human Medicines has advised that Aquiette could be made available as a Pharmacy medicine. Views on the use of this medicine for treatment of long-standing OAB symptoms in women 18 to 65 years of age were also sought at a meeting of the Medicines for Womens Health Expert Advisory Group . The views of the MWH EAG were summarised and provided for CHM when they considered the reclassification application. CHM also considered the views of a stakeholder group on the suitability of oxybutynin as a P medicine.

Aging

OAB occurs in both men and women. Its possible to have overactive bladder at any point in your life. But, its especially common in older adults. The prevalence of OAB in people younger than 50 years of age is less than 10 percent. After the age of 60, the prevalence increases to 20 to 30 percent.

The following are some of the other most common underlying causes and risk factors associated with OAB symptoms:

Nerve Damage

A healthy, normal functioning bladder holds urine until it gets full and is prompted to empty by nerve signals. However, when nerve damage occurs in the body, the muscles surrounding the urethra can be too loose. This undesirable looseness can cause someone to become incontinent. What can cause nerve damage that can then lead to bladder leakage? Some possibilities include:

  • Back or pelvis surgery
  • Stroke

Weak pelvic muscles

When a man or womans pelvic floor muscles are weak, bladder control issues can happen. The pelvic floor muscles are like a sling that holds up the uterus and bladder. For women, a pregnancy and childbirth can often lead to a stretching and weakening of the vital pelvic floor muscles. When pelvic floor muscles are compromised for this reason or another, the bladder can then sag out of place. The opening of the urethra also stretches and urine easily leaks out.

Who Can And Cannot Take Oxybutynin

Oxybutynin can be taken by adults and children aged 5 years or over.

Oxybutynin is not suitable for some people. To make sure it’s safe for you, tell your doctor before starting oxybutynin if you have:

  • ever had an allergic reaction to oxybutynin, any of its ingredients or any other medicine
  • myasthenia gravis, a rare long-term condition that causes muscle weakness
  • an eye problem called glaucoma
  • difficulty peeing, or an enlarged prostate
  • heart problems, including a very fast heart rate or high blood pressure
  • thyroid, kidney or liver problems

The Medication Isnt Giving You The Results You Want

Its difficult to define success with OAB medicationsits so subjective, depending on how severe your OAB is, how much it impacts your life, and the results youre looking for. For one patient, going through three to four diapers a day on medication is progress for another, its still too many accidents. I have some patients who are thrilled to get up only once at night to use the bathroom, but other patients dont want to get up at all. I would say at least 50% of my patients see improvement in their OAB symptoms. These medications arent a cureyou may still experience some OAB issuesbut they tend to reduce the number of times that OAB affects your life each day, and for a lot of my patients, that really matters.

One thing I stress to patients is the importance of giving the medications time to work. Generally, patients should respond to the medications within a month. If you dont experience any change in your OAB symptoms after a month, talk to your doctorhe or she may increase your dosage to see if that increases the effectiveness of the drug. If that doesnt work, its time to try something new.

    Can Overactive Bladder Medication Harm Your Cognitive Health

    Overactive bladder is a common disorder affecting about 33 million Americans and 30% of people over 65. Research suggests that one of the most popular OAB medications, oxybutynin, may harm brain health and increase dementia risk.

    OAB is a combination of urinary tract symptoms including frequent urination and the inability to control urination. Oxybutynin is a common treatment for OAB that works by relaxing bladder muscles. Its benefits combined with the high prevalence of OAB in the elderly make it a very popular drugover a quarter of all elderly people with OAB have been prescribed oxybutynin. It remains popular despite several studies linking oxybutynin use to cognitive side effects and increased dementia risk. This is troubling because elderly patients are already more at risk for dementia, and oxybutynin may worsen the situation.

    WHAT THE EVIDENCE SAYSOne clinical trial of 12 subjects with an average age of 69 reported that oxybutynin treatment for 6 weeks resulted in significant decreases in 7 out of 15 cognitive measures . A recent observational study was even more alarming. It found that oxybutynin treatment was associated with a 2.3-fold increased risk of dementia in people with diabetes compared to those who did not take this class of medication . However, the evidence is mixed another study found that oxybutynin treatment did not result in cognitive impairment compared to placebo in nursing home residents with cognitive impairment .

    What Are The Side Effects Of Oxybutynin

    The most common side effects of oxybutynin are dry mouth, constipation, tiredness, and headache. About 1 in every 14 patients taking oxybutynin tablets cannot tolerate it because of side effects. Diarrhea, urinary tract infections, blurred vision, and difficulty urinating also may occur. The transdermal patch or gel may also cause local reactions at the application sites such as itching and rash. Transdermal patches or gel cause fewer side effects than the tablets. Serious hypersensitivity reactions involving swelling of the throat, lips, and tongue also may occur.

    Could Your Overactive Bladder Be Something Else

    Oxybutynin nets dramatic reduction in hot flashes

    Urgency, incontinence, and urinary frequency can all be caused by having urinary tract infections , kidney stones, prostate infection or enlargement, or could be from medicine you take to treat other conditions, such as high blood pressure. The first question your doctor might ask if youre having urinary problems is what medicines youre taking. If they dont ask, be sure to bring it up.

    Other conditions can cause symptoms similar to those of overactive bladder, tooespecially the need to make frequent bathroom trips. These include bladder cancer, diabetes, heart disease, and neurologic disorders, such as multiple sclerosis, Parkinsons disease, spinal cord injuries, and strokes.

    Other conditions can also cause urine leakage. For example, stress incontinenceleaking urine when you cough, sneeze, run, jump, or even laughis sometimes confused with overactive bladder. Its caused by a weakness of the muscles that help keep the bladder closed. Some people have a combination of overactive bladder and stress incontinence.

    Another bladder disorder called overflow incontinence can have symptoms similar to overactive bladder. This condition is usually caused by an inability to empty the bladder, due to an obstruction or a problem with the muscles that contract the bladder. So much urine builds up in the bladder that it starts leaking out.

    How Can Pelvic Floor Exercises Help Someone With Oab

    Pelvic floor exercises can help strengthen and condition the pelvic musculature. Some people with OAB may experience urge-related incontinence, leaking small or sometimes large volumes of urine when the urge to urinate comes on strong and they do not have time to make it to the bathroom.

    Increasing pelvic muscle strength can lead to an increase in the tone of a persons urethral sphincters . This may provide more protection against leakage.

    On the other hand, relaxation techniques can help ensure people empty their bladders completely when urinating. Functional capacity of the bladder decreases if a person carries extra urine around in their bladder, which can then decrease the time it takes for the bladder to feel full.

    Botox comes from the bacteria Clostridium botulinum, which makes several different neurotoxins. For the bladder, doctors use onabotulinatoxinA.

    As the authors of a 2020 research review explain, it works by blocking acetylcholine release at the nerve ganglion level, which prevents bladder muscle contraction.

    During a simple office-based or operating room procedure, a healthcare professional inserts a cystoscope into the urethra. They then inject Botox into the bladder wall in a grid-like fashion.

    However, the effects of the toxin wear off over the course of 36 months. According to a

    • Botox injection, as described above
    • peripheral tibial nerve stimulation
    • sacral neuromodulation

    Epidemiology. Studies assessing how OAB develops and its natural history and progression are required. The timing and circumstances around which OAB develops and associated risk factors are not yet well-understood. While not specifically targeting epidemiology of OAB, there are large community-based studies that assess prevalence of lower urinary tract symptoms and urinary incontinence.280, 281 By longitudinally studying these community cohorts, these investigators have developed a new hypothesis that lower urinary tract symptoms are likely related to other systemic diseases/conditions.282, 283 Continuation of these types of studies could lead to potential preventive interventions for OAB symptoms and/or utilization of treatments that target the associated systemic conditions rather than the bladder. Epidemiologic studies provide a better cross sectional estimation of the overall population impact of OAB-type symptoms.284

    Clinical studies should use validated standardized measures to report subjective outcomes. Objective outcomes should include frequency, nocturia, urgency, incontinence episode frequency and reporting of the variance for each of these measures. Furthermore, the Guideline Panel’s meta-analytic efforts were hampered by lack of consistent reporting of variance information for baseline and post-treatment measurements.
