Ditropan is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination, by decreasing muscle spasms of the bladder. It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor.

Medicinal name:
  • 24 HR Oxybutynin chloride 10 MG Extended Release Oral Tablet [Ditropan]
  • 24 HR Oxybutynin chloride 15 MG Extended Release Oral Tablet [Ditropan]
  • 24 HR Oxybutynin chloride 5 MG Extended Release Oral Tablet [Ditropan]

Ditropan - Pharmacology:

Ditropan exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects).

Ditropan for patients

Patient should be informed that oxybutynin may produce drowsiness or blurred vision. Alcohal may enhance the drowsiness caused by anticholinergic agents. Fever and heat stroke can occur while anticholinergics are administered in the presence of high environmental temparature. Medication should be taken with the aid of liquids at approximately the same time each day. Patients should not chew, divide, or crush tablets.

Ditropan Interactions

The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects.

Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index.

Mean oxybutynin chloride plasma concentrations were approximately 2 fold higher when DITROPAN XL was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered.

Concurrent ingestion of antacid (20 mL of antacid containing aluminum hydroxide, magnesium hydroxide, and simethicone) did not significantly affect the exposure of oxybutynin or desethyloxybutynin.


Ditropan Contraindications

DITROPAN XL® is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions.

DITROPAN XL is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product.
