Antispasmodics (GU): Nursing pharmacology

Definitions & Key takeaways

Urinary antispasmodics are medications used to inhibit bladder contractions, which can help manage symptoms of conditions such as urge incontinence, overactive bladder, and urinary tract infections.

The most commonly used urinary antispasmodics include antimuscarinic medications like tolterodine, flavoxate, and oxybutynin, as well as beta-3 adrenergic agonists like mirabegron, which can be administered orally or topically. The way these work is by inhibiting the effects of the parasympathetic nervous system on the detrusor muscle, causing it to relax. Possible side effects include dry mouth, constipation, dizziness, and blurred vision.

As with any medication, nursing considerations for urinary antispasmodics include performing a thorough baseline assessment, educating the client about potential side effects, and monitoring for therapeutic effects of the medication.

Urinary antispasmodics are medications that can be used to reduce involuntary contractions or spasms of the detrusor muscle, which is a wall of smooth muscle that surrounds the bladder.
These spasms cause a sudden and frequent urge to urinate, and could result from conditions like urge incontinence or overactive bladder, as well as from a urinary tract infection or injury.The most commonly used urinary antispasmodics include antimuscarinic medications like tolterodine, flavoxate, and oxybutynin, as well as beta-3 adrenergic agonists like mirabegron, which can be administered orally or topically.
The way these work is by inhibiting the effects of the parasympathetic nervous system on the detrusor muscle, causing it to relax.Now, side effects commonly associated with urinary antispasmodics include headaches, dizziness, and drowsiness.
In addition, clients may experience dry eyes and blurry vision, as well as dry mouth and dry skin. Some clients may also have tachycardia, nausea, vomiting, constipation, urinary retention, as well as anxiety and restlessness.
Finally, the most severe side effects of urinary antispasmodics include hyperthermia, confusion, and delirium. As far as contraindications go, urinary antispasmodics should not be given to clients with intestinal or urinary obstruction, as well as those with hypertension or cardiovascular disease.
Another contraindication is narrow angle glaucoma, since these medications can worsen the obstruction of aqueous humor drainage.
Finally, urinary antispasmodics are contraindicated in clients with myasthenia gravis.Okay, when caring for your client with an overactive bladder who is prescribed a urinary antispasmodic, first obtain a baseline assessment of your client’s urinary symptoms, such as frequency, urgency, nocturia, and the degree of incontinence they are experiencing.
Then, assess your client’s vital signs. Finally, review their laboratory test results, specifically BUN, creatinine, kidney function tests, as well as urinalysis and urine culture.Be sure your client understands why they have been prescribed this medication and how it will help them with their symptoms.
Next, explain that an extended release tablet should be taken whole, never crushed or chewed, and that it can be taken with or without food.
If your client is prescribed a transdermal patch, instruct them to apply it on dry, smooth, intact skin that is free of lotions, oils or powders; and recommend the abdomen, hip or buttocks as ideal spots for the patch; in addition, explain the importance of rotating the application site to a different spot each time.
Then, explain some strategies that can help decrease urinary frequency and episodes of incontinence, such as emptying their bladder on a regular basis, pelvic floor strengthening exercises, and avoiding caffeine.
Next, let your client know how to manage some of the side effects they may experience. If they experience blurred vision, dizziness or drowsiness, advise them to avoid activities that require alertness, such as driving, until they adjust to the medication.
Be sure to tell your client that they may experience dry eyes while taking their medication, and advise them that lubricating eye drops can be helpful.
And, if they experience dry mouth, suggest they use sugar-free hard candy or gum, as well as frequent sips of water. In addition, remind your client that the risk of constipation can be reduced by increasing their dietary fiber and physical activity.
Lastly, stress the importance of immediately reporting signs or symptoms that could indicate a rise in blood pressure, such as headaches, dizziness, or a change in vision; as well as if they have trouble emptying their bladder, or other concerning symptoms such as anxiety, restlessness or confusion.
Finally, during treatment, monitor for any side effects they may experience, as well as the therapeutic effects of the medication, including decreased urinary frequency and urgency, decreased nocturia, as well as decreased episodes of incontinence.##SummaryAlright, as a quick recap ….
Urinary antispasmodics are medications that inhibit bladder contractions, which can cause a sudden and frequent urge to empty the bladder in conditions like urge incontinence, overactive bladder, and urinary tract infections.
Some urinary antispasmodics work by blocking the muscarinic receptors, and others work by stimulating the beta-3 adrenergic receptors.
Nursing considerations for urinary antispasmodics include performing a baseline assessment, providing client education about side effects they may experience, and monitoring for the therapeutic effects of the medication.
