Efficacy and safety of solifenacin plus tamsulosin oral controlled absorption system in men with lower urinary tract symptoms: a meta-analysis

The Analysis of the Effects of Executive Functions, Working Memory and Other Factors on Medication Adherence in Elderly Men with Benign Prostatic Hyperplasia and Overactive Bladder Symptoms

AIM

Evaluation of the executive function and working memory influence, as well as the general state of memory, on adherence to Benign Prostatic Hyperplasia (BPH) and overactive bladder symptoms treatment in elderly men.

BACKGROUND

The influence of the executive function and working memory on treatment adherence in older men with BPH has not been studied enough.

OBJECTIVE

To determine the level of influence of various factors on the treatment adherence in older men with BPH.

METHODS

The executive function and working memory evaluation, as well as a general memory assessment, were carried out using the Wisconsin Test, the Wechsler Memory Scale, and the California Verbal Test. Hierarchical and simultaneous regressions were calculated to study the effect of executive function and working memory.

RESULTS

After the end of the study, the symptoms of hyperactive bladder significantly decreased, the symptoms of evacuation did not change significantly, and the cognitive status of the patients remained unchanged. The predictor variables significantly influencing adherence of elderly men to BPH and overactive bladder (OAB) treatment are executive function and working memory composite (β = .33, p < .05), severe symptoms of lower urinary tract (-.34, p < .05), and age (-.27, p < .05).

CONCLUSION

The status of executive function and working memory, as well as the age and severity of the pathological symptoms of the lower urinary tract, should be taken into account when predicting the risks of rejecting BPH and OAB treatment in elderly patients.

Efficacy and safety of tamsulosin hydrochloride 0.2 mg and combination of tamsulosin hydrochloride 0.2 mg plus solifenacin succinate 5 mg after transurethral resection of the prostate: a prospective, randomized controlled trial

Objective

The objective of this study was to evaluate the safety and efficacy of tamsulosin hydrochloride 0.2 mg (TAM) and its combination with solifenacin succinate 5 mg (SOL) after transurethral resection of the prostate (TURP).

Patients and methods

The patients were randomized into three groups: TURP (group 1), TURP plus TAM (group 2), and TURP plus TAM + SOL (group 3). Patients in group 2 and group 3 received medication for 4 weeks. The primary efficacy end points were the mean change in total International Prostate Symptom Score (IPSS) and IPSS subscores. The secondary end points included quality-of-life score, Overactive Bladder Symptom Score, and short-form voiding and storage score of International Continence Society.

Results

In total, 37 men (31.8%) in group 1, 37 men (31.8%) in group 2, and 42 men (36.2%) in group 3 completed the study. In total IPSS, no significant improvement was seen from baseline to the end of treatment in groups 2 and 3 compared with group 1. However, in group 2, the decrement in the IPSS storage score was smaller than group 1 (P=0.02), and in group 3, the decrement in the IPSS voiding score was smaller than group 1 (P=0.05). In groups 2 and 3 compared with group 1, improvements in the quality of life score, total score of Overactive Bladder Symptom Score, and short-form voiding score and storage score of International Continence Society were not statistically significant.

Conclusion

Treatment with TAM and combination of TAM and SOL did not have significant additional benefits for lower urinary tract symptoms during the early recovery period after TURP.

Efficacy and safety of tamsulosin oral-controlled absorption system, solifenacin, and combined therapy for the management of ureteric stent-related symptoms

Objectives

To evaluate the efficacy of solifenacin, tamsulosin oral-controlled absorption system (OCAS), and the combination of both drugs on JJ stent-related symptoms using the validated Arabic version of the ureteric stent symptom questionnaire (USSQ).

Patients and methods

In all, 260 patients who had undergone JJ stenting of the ureter for different endoscopic urological procedures were postoperatively randomly assigned into four equal groups. Patients in Group I received no treatment and served as the control group, Group II patients received tamsulosin OCAS 0.4 mg daily, Group III patients received solifenacin 5 mg daily, and Group IV patients received a combination of both drugs. Before stent removal, all patients completed the Arabic version of the USSQ.

Results

In all, 234 patients completed the study, comprised of 56 in Group I, 59 in Group II, 58 in Group III, and 61 in Group IV. Baseline characteristics and indications for JJ stenting were comparable in the four groups. There were highly significant differences in all items of the USSQ between the treatment groups and the controls, while Group II and III were comparable. The USSQ score was significantly lower in Group IV vs Groups II and III. Crossing of the distal curl of the stent to the midline had a significant positive correlation with the severity of the urinary symptoms, body pain, general health, and work performance in the medicated groups.

Conclusions

Combined therapy with tamsulosin OCAS 0.4 mg daily and solifenacin 5 mg daily is a safe and well-tolerated management for stent-related symptoms. However, stent position remains a significant factor affecting response to medical therapy and patients’ health-related quality of life.

Combination therapy with tamsulosin and solifenacin for male lower urinary tract symptoms with predominant filling symptoms: a new approach to an old problem

Benign prostatic enlargement is the main cause of male lower urinary tract symptoms (LUTS). The distinction and quantification of voiding, storage and postmicturition symptoms help clinicians decide on a modern pharmacological therapeutic approach for male LUTS. Muscarinic receptors antagonists are now considered safe therapy in males and a fixed-dose combination of oral controlled absorbed system solifenacin and tamsulosin is advantageous compared to tamsulosin monotherapy in males with predominant storage symptoms when validated instruments such as International Prostatic Score Symptoms (IPSS) or Total Urgency Frequency Score (TUFS) are used. This combination therapy is well tolerated and maintains symptomatic improvement in the long term. Different options of managing male LUTS with predominant storage symptoms include a combination of tamsulosin and solifenacin, antimuscarinics alone - some with flexible dosing, and the beta-3 agonist mirabegron. Tailored pharmacological therapy for the particular patient is not a reality yet, but judicious use of the different alternatives could bring varied new therapeutic solutions for male LUTS including benign prostatic enlargement and benign prostatic obstruction.

Tamsulosin combined with solifenacin versus tamsulosin monotherapy for male lower urinary tract symptoms: a meta-analysis

OBJECTIVE

To evaluate the efficacy and safety of tamsulosin and solifenacin combination therapy compared with tamsulosin monotherapy for male lower urinary tract symptoms (LUTS).

METHODS

We identified all eligible studies that compared tamsulosin and solifenacin combination therapy with tamsulosin monotherapy for male LUTS (up to January 2015). The fixed- or random-effects model was selected depending on the proportion of heterogeneity.

RESULTS

Seven articles were identified as eligible for this meta-analysis, with a total of 3063 participants. Synthetic data showed combination therapy had significant improvements in Storage International Prostate Symptom Score (WMD = -0.60; 95% CI: -0.81 to -0.38, P < 0.0001), quality of life (WMD = -0.23; 95% CI: -0.34 to -0.11, P < 0.0001), micturitions per 24 hours (WMD = -0.70; 95% CI: -0.86 to -0.55, P < 0.0001) and urgency episodes per 24 hours (WMD = -0.26; 95% CI: -0.48 to -0.05, P = 0.018). The incidence of adverse effects in the tamsulosin and solifenacin combined therapy group (30.82%) was similar to the tamsulosin monotherapy group (25.75%). Acute urinary retention was seldom reported in the studies and no clinically significant changes regarding Qmax were showed in our meta-analysis.

CONCLUSIONS

Tamsulosin and solifenacin combination therapy may be a reasonable option for male LUTS patients, especially for those who have significant storage symptoms. However, PVR should be measured during treatment to assess the increase in PVR or the incidence of AUR.
