Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • For the without-urgency group:

    • urinary frequency ≥ 8 micturitions per 24 hours no urgency on voiding diary (1 or 2 on a 5 urgency scale)
  • For the with-urgency group:

    • urinary frequency ≥ 8 micturitions per 24 hours symptoms of urinary urgency≥ 2/day on the voiding diary (3 to 5 on a 5 urgency scale)
  • Symptoms lasting for more than 3 months

Exclusion Criteria:

  • Clinically significant stress incontinence as determined by the investigator; for female patients, clinically significant stress incontinence confirmed by a cough provocation test
  • Total daily urine volume of > 3000 mL as verified on the micturition diary before randomization
  • Significant hepatic or renal disease, defined as having twice the upper limit of the reference ranges for serum concentrations of aspartate aminotra
  • Any condition that is a contraindication for anticholinergic treatment, including uncontrolled narrow-angled glaucoma, urinary retention or gastric retention
  • Symptomatic acute urinary tract infection (UTI) during the run-in period
  • Recurrent UTIs defined as having been treated for symptomatic UTIs > 4 times in the last year
  • Diagnosed or suspected of interstitial cystitis
  • Uninvestigated hematuria or hematuria secondary to a malignant disease
  • Clinically significant bladder outlet obstruction defined by clinical symptoms and investigator's opinion according to local standard of care (residual urine> 100mL of functional bladder capacity)
  • Patients with marked cystocele or other clinically significant pelvic prolapse
  • Treatment within 14 days preceding randomization, or expected to initiate treatment during the study with:

    • Any anticholinergic drugs other than a randomized trial drug
    • Any drug treatment for overactive bladder. Estrogen treatment started more than 2 months prior to inclusion is allowed
  • On an unstable dosage of any drug with anticholinergic side effects, or expected to start such treatment during the study
  • Receipt of any electrostimulation or bladder training within 14 days before randomization, or expected to start such treatment during the study
  • An indwelling catheter or practicing intermittent self-catheterization
  • Use of any investigational drug within 1 month prior to the start of the study
  • Patients with chronic constipation or history of severe constipation
  • Pregnant or nursing women
  • Sexually active females of childbearing potential not using reliable contraception for at least 1 month prior to the start of the study and not agreeing to use such methods during the entire study period and for at least 1 month thereafter. Reliable contraceptive methods are defined as intrauterine devices (IUDs), combination type contraceptive pills, hormonal implants, double barrier method, injectable contraceptives and surgical procedures (tubal ligation or vasectomy)
  • Patients who have bladder cancer or prostate cancer
  • Treatment with potent CYP3A4 inhibitors, such as cyclosporine, vinblastine, macrolide antibiotics (e.g. erythromycin, clarithromycin, azithromycin) or antifungal agents (e.g. ketoconazole, itraconazole, micronazole)
  • Patients who have neurological disease
  • Patients who have psychological disease
  • Any other condition which, in the opinion of the investigator, makes the patient unsuitable for inclusion
