Chemical structure of Propiverine

Propiverine is a medication used to treat overactive bladder symptoms, such as urinary incontinence, urinary urgency, and urinary frequency. It is classified as an anticholinergic and antispasmodic agent.

Mechanism of Action

Propiverine works by inhibiting the muscarinic acetylcholine receptors in the bladder, which reduces the contractions of the bladder muscle. This action helps to increase the bladder's capacity and reduce the frequency of urination. Additionally, propiverine has a direct spasmolytic effect on the smooth muscle of the bladder.

Pharmacokinetics

Propiverine is administered orally and is absorbed in the gastrointestinal tract. It undergoes extensive first-pass metabolism in the liver, and its metabolites are excreted primarily in the urine. The half-life of propiverine is approximately 14 to 20 hours, allowing for once or twice daily dosing.

Side Effects

Common side effects of propiverine include dry mouth, constipation, blurred vision, and dizziness. These side effects are typical of anticholinergic medications. In some cases, patients may experience urinary retention, tachycardia, or gastrointestinal disturbances.

Contraindications

Propiverine is contraindicated in patients with narrow-angle glaucoma, myasthenia gravis, severe ulcerative colitis, and toxic megacolon. It should be used with caution in patients with hepatic impairment or renal impairment.

Clinical Use

Propiverine is primarily used in the management of overactive bladder in adults. It may also be used in certain cases of neurogenic bladder dysfunction. The typical starting dose is 15 mg once daily, which may be adjusted based on the patient's response and tolerance.
