Osmosis video - Antispasmodics (GU): Nursing pharmacology

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.
