Abstract
Objective To evaluate the efficacy and safety of low-dose (2 mg) tolterodine extended release (ER) with an a-blocker compared with standard-dose (4 mg) tolterodine ER with an a-blocker for the treatment of men with residual storage symptoms after a-blocker monotherapy. Patients and Methods The study was a 12-week, single-blind, randomized, parallelgroup, non-inferiority trial that included men with residual storage symptoms despite receiving at least 4 weeks of ablocker treatment. Inclusion criteria were total International Prostate Symptom Score (IPSS) ≥12, IPSS quality-of-life item score ≥3, and ≥8 micturitions and ≥2 urgency episodes per 24 h. The primary outcome was change in the total IPSS score from baseline. Bladder diary variables, patient-reported outcomes and safety were also assessed. Results Patients were randomly assigned to addition of either 2 mg tolterodine ER (n = 47) or 4 mg tolterodine ER (n = 48) to a-blocker therapy for 12 weeks. Patients in both treatment groups had a significant improvement in total IPSS score ( 5.5 and 6.3, respectively), micturition per 24 h ( 1.3 and 1.7, respectively) and nocturia per night ( 0.4 and 0.4, respectively). Changes in IPSS, bladder diary variables, and patient-reported outcomes were not significantly different between the treatment groups. All interventions were well tolerated by patients. Conclusions These results suggest that 12 weeks of low-dose tolterodine ER add-on therapy is similar to standard-dose tolterodine ER add-on therapy in terms of efficacy and safety for patients experiencing residual storage symptoms after receiving ablocker monotherapy.
