Oxybutynin functions by inhibiting the action of acetylcholine on muscarinic receptors found in the bladder. This inhibition leads to the relaxation of the detrusor muscle, which is responsible for the involuntary contractions that cause the urgency and frequency of urination associated with overactive bladder syndrome. The versatility in its formulations allows for flexibility in administration, catering to different patient needs and preferences.

SKU: N/A Category:


Oxybutynin is a medication extensively used in the management of overactive bladder and related conditions that exhibit symptoms such as frequent or urgent urination, incontinence, and nocturia. It belongs to the class of drugs known as antimuscarinics or anticholinergics, which work by relaxing the bladder muscles. Oxybutynin effectively reduces bladder muscle spasms, thereby decreasing urination’s urgency and frequency. It is available in various forms, including oral tablets, transdermal patches, and topical gels.

Administration Guidelines

●Oral Tablets: Oxybutynin oral tablets are typically taken two to three times daily, with or without food. Swallow the tablets whole with a glass of water; do not chew, break, or crush them.

●Transdermal Patches: The patch should be applied to a clean, dry, and smooth skin area on the abdomen, hip, or buttock. A new patch is usually applied twice weekly (every 3–4 days), and the application site should be rotated to avoid skin irritation.

●Topical Gel: A measured dose of the gel is applied to clean, dry skin on the abdomen, upper arms, shoulders, or thighs once daily. Do not apply the gel to recently shaved or broken skin.
