Urge incontinence, Urinary frequency and urgency, Overactive bladder

Oral Overactive bladder Adult: For symptomatic treatment of urge incontinence, urinary frequency and urgency. Initial: 7.5 mg once daily; may increase dose to 15 mg once daily if no adequate response after 2 wk of therapy. Hepatic impairment: Moderate hepatic impairment (Child Pugh B): Maximum daily dose is 7.5 mg. Severe hepatic impairment (Child Pugh C): Not recommended.
Patient with urinary retention, gastric retention, uncontrolled narrow-angle glaucoma, and in patients who are at risk for these conditions.
Darifenacin is a potent, competitive and selective muscarinic receptor antagonist which has greater binding affinity for muscarinic M3 receptors. M3 receptors are involved in the contraction of the detrusor muscle of the bladder, GI smooth muscle, saliva production, and iris sphincter function. Darifenacin may increase volume threshold in patients with involuntary detrusor contraction, thus increase bladder capacity.
Anticholinergic agents including Darifenacin, may cause urinary retention and decreased GI motility. Caution when used in patients with clinically significant bladder outflow obstruction, GI obstructive disorder (e.g. pyloric stenosis), severe constipation, ulcerative colitis, and myasthenia gravis. For patients being treated for narrow-angle glaucoma, caution and only use where potential benefits outweigh the risks. May cause heat prostration when used in a hot environment. May cause dizziness and blurred vision; caution when operating machinery or driving vehicle. Not recommended in severe hepatic impairment. Safety and efficacy have not been established in paediatric patients. Pregnancy and lactation. Lactation: Excretion in milk unknown; use caution

Concurrent use of CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, clarithromycin, nefazodone, troleandomycin, ritonavir, nelfinavir) or CYP2D6 inhibitors (e.g. quinidine, paroxetine) may increase serum levels of Darifenacin. CYP3A4 inducers (e.g. barbiturates, phenytoin, rifampicin) may likely decrease Darifenacin serum concentrations. Darifenacin may act as a moderate inhibitor of CYP2D6, caution when used concomitantly with CYP2D6 substrates that have narrow therapeutic index (e.g. flecainide, thioridazine, imipramine). Concurrent use of another agent with antimuscarinic properties may potentiate the side effects of Darifenacin.
