Health video advice on the medication Oxybutynin: when and how to administer this active ingredient. Video advice presented by pharmacist Eduardo Ramírez, prepared by the General Council of Pharmaceutical Colleges and produced by Medicina TV. Oxybutynin is a drug that belongs to the group of medications called urinary antispasmodics, which acts on bladder contractions and delays the urge to urinate. Specifically, oxybutynin is an antagonist of the neurotransmitter acetylcholine at muscarinic receptors present in the bladder, which produces relaxation of the smooth muscle. Medications containing oxybutynin are available in pharmacies in the form of 5 mg tablets and 36 mg transdermal patches, always with a prescription. The tablets are indicated for patients 5 years of age and older for the symptomatic treatment of urge urinary incontinence and increased urinary frequency associated with overactive bladder, a condition in which the bladder contracts involuntarily before it is full, or with neurogenic bladder dysfunction. They are also used for nocturnal enuresis associated with detrusor overactivity, in conjunction with non-pharmacological treatment and if other treatments have failed. The patches are used for the symptomatic treatment of overactive bladder exclusively in adults. The usual dose of tablets is 2-3 tablets daily for adults, taken with plenty of liquid to ensure passage. For children over 5 years of age, the recommended dose is 2 tablets daily, spaced at least 4 hours apart. The patches should be applied once a day to a clean, dry, smooth area of skin on the abdomen, hip, or buttocks, avoiding sun exposure, and avoiding applying two patches to the same area within a 7-day period. Oxybutynin is contraindicated in patients who suffer from or are at risk of developing urinary retention, severe obstructive gastrointestinal disorders, narrow-angle glaucoma, or myasthenia gravis, a rare neuromuscular disorder characterized by muscle weakness. It should also not be used during pregnancy unless the physician determines it is essential, and its use is not recommended during breastfeeding. It should be used with caution in patients with renal or hepatic impairment. Furthermore, before considering treatment with oxybutynin, the physician will rule out other causes of urinary dysfunction, such as heart failure, kidney disorders, or urinary tract infection. For oral administration, the most frequent adverse reactions include headache, drowsiness or dizziness, constipation, dry mouth or nausea, blurred vision, and dry skin. With patch treatment, the most frequent are application site reactions, followed by dry mouth, constipation, diarrhea, and headache. And remember, always ask your trusted pharmacist.
