Time-to-effect with darifenacin in overactive bladder: a pooled analysis. [2011] with darifenacin in patients with overactive bladder (OAB)... CONCLUSIONS: Darifenacin 7.5 and 15 mg significantly reduced OAB symptoms
Darifenacin treatment for overactive bladder in patients who expressed dissatisfaction with prior extended-release antimuscarinic therapy. [2008.11] INTRODUCTION AND OBJECTIVE: Patient perception of overactive bladder (OAB) treatment outcomes can be a useful indicator of benefit and may help drive persistence on treatment, which is known to be poor in OAB. It remains unclear whether OAB patients dissatisfied with one antimuscarinic can achieve satisfaction with another and supporting data are limited. This study investigated patient-reported outcomes and clinical parameters during darifenacin treatment in OAB patients who expressed dissatisfaction with prior extended-release (ER) oxybutynin or tolterodine therapy (administered for >or= 1 week within the past year)... CONCLUSIONS: In this study, PPBC score and OAB symptoms were significantly improved, and satisfaction was high during treatment with darifenacin (7.5/15 mg) in patients who were dissatisfied with the previous antimuscarinic treatment.
Clinical relevance of health-related quality of life outcomes with darifenacin. [2008.07] OBJECTIVE: To determine the clinical relevance of changes in health-related quality of life (HRQoL) in patients with overactive bladder (OAB) treated with darifenacin... CONCLUSIONS: Darifenacin treatment was associated with significant, clinically relevant improvements in HRQoL in patients with OAB, shown using the concept of MID to interpret change in KHQ scores.
Long-term benefits of darifenacin treatment for patient quality of life: results from a 2-year extension study. [2008] BACKGROUND AND AIMS: Overactive bladder (OAB), a chronic condition requiring long-term management, is associated with substantial impact on health-related quality of life (HRQoL). The short-term benefits of antimuscarinic drug treatment are well known. Here we investigate the impact on HRQoL of long-term treatment with the M(3)-selective muscarinic receptor antagonist darifenacin over 2 years... CONCLUSIONS: Long-term darifenacin treatment was associated with significant and clinically meaningful improvements in HRQoL for patients with 'wet' OAB over 2 years. (c) 2008 Wiley-Liss, Inc.
Darifenacin treatment of patients >or= 65 years with overactive bladder: results of a randomized, controlled, 12-week trial. [2007.10] BACKGROUND: Overactive bladder (OAB) increases in prevalence with advancing age. This study specifically investigated patients >or= 65 years, evaluating the efficacy, tolerability, safety and quality of life (QoL) outcomes from darifenacin treatment... CONCLUSIONS: This study demonstrated that marked improvements in OAB symptoms can be achieved in patients >or= 65 years, with significant treatment differences in responder rates, micturition frequency and QoL. Reduction in UUIEs may not be the optimal endpoint in this population, whereas QoL appears to be a sensitive and relevant patient-oriented measure of treatment effect.
Clinical Trials Related to Enablex (Darifenacin)
Single Dose Two-periods Crossover Bioequivalence Study of Darifenacin Tablets in Healthy Volunteers. [Not yet recruiting]
The present study was designed to assess the bioequivalence and pharmacokinetic profiling of
a brand generic formulation of darifenacin [Darisec(R)]vs. the innovator [Enablex(R)]in
healthy volunteers after a high fat breakfast.
The bioequivalence will be evaluated using:
- the Area Under the Curve (AUC) and,
- the peak plasma concentration (Cmax).
Safety will be evaluated recording:
- vital signs
- adverse events,
- laboratory analysis.
- EKG and chest XRays.
Bioequivalence will be claimed if the drugs comply with local regulatory requirement, eg.:
- mean AUCt/AUCr and 90% confidence interval within 0. 80-1. 25
- mean Cmaxt/Cmaxr and 90% confidence interval within 0. 80-1. 25.
Single Dose Bioequivalence Study of Darifenacin Tablets 7.5 mg in Fed Healthy Volunteers. [Not yet recruiting]
The proposed study was designed as a randomized two-sequence, two period crossover trial to
assess the bioequivalence, pharmacokinetic profiling and safety of a brand generic
formulation of darifenacin [Darisec(R) 7. 5 mg] vs. the innovator [Enablex(R)7. 5 mg]in
healthy volunteers in postprandial state.
2 Week Open-label Pharmacodynamic and Pharmacokinetic Study of Multiple Doses of a Darifenacin Liquid Oral Suspension in Children (2 - 15 Yrs) With Neurogenic Detrusor Overactivity [Suspended]
This study will evaluate the pharmacodynamics and pharmacokinetics of darifenacin liquid
oral suspension in children, ages 2-15 years, with neurogenic detrusor overactivity. The
results will support a benefit-risk based dosage recommendation for phase IIIa clinical
trials.
Preoperative Use of Darifenacin (Enablex) to Alleviate Postoperative Ureteral Stent Pain [Recruiting]
This will be a randomized two arm prospective study to evaluate postoperative ureteral stent
pain. One arm will be given 3 days of preoperative darifenacin and the control group will
have the standard of care which is no preoperative anticholinergic medication. The primary
endpoints will be decreased pain scores and less ER visits and hospital admissions for stent
difficulty. These will be assessed by a pain diary completed by the participant as well as a
questionnaire when the participant returns to clinic for stent removal. Also included in
evaluation of the primary end point will be patient phone calls, ER visits and admissions
for stent difficulty. Secondary endpoints will be narcotic and postoperative anticholinergic
use. This will also be assessed with the pain diary completed by the participant.
Participants will be included in the study if they are undergoing a procedure that a stent
will likely be required. This will include participants who will have ureteroscopy or
extracorporeal shock wave lithotripsy and a stone 1 cm or larger. Also participants with
stones smaller than 1 cm who due to anatomy of the ureter or kidney will likely need a stent
on preoperative evaluation will also be included in the study. Included as well in the study
are participants who will undergo renal or ureteral surgery that a ureteral stent will be
utilized. Participants will be randomized after consent is obtained into two groups. One
group will receive standard of care which is no preoperative anticholinergic medications.
The second group will receive the three day treatment with darifenacin pre procedure.
Participants in the second group will be instructed on side effects of darifenacin and given
appropriate contact information prior to initiation of the medication. Both groups will be
followed postoperatively with a pain diary. Postoperative follow up will continue until the
stent is removed 1-2 weeks after the procedure. The exact time of stent removal will depend
on the success and nature of the surgery and will be at the discretion of the surgeon.
Participants will be able to voluntarily stop the medication for any reason as well as if
they have serious side effects from the medication. Data to be collected from each group
includes age, gender, race, prior ureteral stents, prior renal or ureteral surgery, past
medical history, allergies, current medications and urinary complaints.
Efficacy of Darifenacin and Physiotherapy for the Treatment of Overactive Bladder in Women [Recruiting]
Overactive bladder is a common problem among adult women. Darifenacin is an antimuscarinic
drug that is frequently used as part of the management of the condition. However, current
evidence backing its use is limited. This study aims to address Darifenacin's effectiveness
in adjunct to physiotherapy in treating symptoms due to overactive bladder.
