EVIDENCE SYNTHESIS The most studied combination therapy for the treatment of male LUTS is the α1-adrenoceptor antagonist/5α-reductase inhibitor combination .
This combination seems to be more efficacious in terms of several outcome variables , in particular in men who have moderate-to-severe LUTS and are at risk of disease progression .
Also in terms of nocturia improvements , this combination is significantly more effective than the monotherapy .
The other often studied combination treatment , in both male and female patients with LUTS , was the combination of antimuscarinics ( in particular solifenacin ) and mirabegron .
This combination seems to be more effective in comparison with the monotherapies with respect to urinary incontinence and urgency urinary incontinence episodes and several other objective and subjective parameters , without relevant increase of adverse events .
The combination of hormone therapy and antimuscarinics in women with LUTS does not seem to be useful .
For the treatment of LUTS in men and women , combination therapy appears to be a promising option to optimize the efficacy of the available drugs for those who do not experience sufficient benefit with monotherapy .
This add-on scenario offers the possibility to have a more tailored approach to the management of LUTS , always seeking the optimal balance between efficacy and tolerability for a given patient .
PATIENT SUMMARY Some combination of drugs may offer advantages over monotherapies for the treatment of voiding and storage complaints in men and women
CONTEXT Several drugs are approved and available for the treatment of lower urinary tract symptoms ( LUTS ) in men and women .
However , the vast majority of available data , upon which the approval and recommendation in guidelines are based , considered only the role of the monotherapies and did not evaluate possible combination therapies .
OBJECTIVE This systematic review analyzes the efficacy and adverse events of combination therapies for male and female LUTS .
A randomized controlled study of the efficacy of tamsulosin monotherapy and its combination with mirabegron for overactive bladder induced by benign prostatic obstruction.
PURPOSE We evaluated the efficacy and safety of add-on treatment with a β3-adrenoceptor agonist ( mirabegron ) for overactive bladder symptoms remaining after α1-blocker ( tamsulosin ) treatment in men with benign prostatic obstruction . MATERIAL S AND METHODS Patients with benign prostatic obstruction with urinary urgency at least once per week and a total OABSS of 3 or more points after 8 or more weeks of treatment with tamsulosin were enrolled in the study . They were r and omly allocated to receive 0.2 mg tamsulosin daily or 0.2 mg tamsulosin and 50 mg mirabegron daily for 8 weeks . The primary end point was change in total OABSS . Safety assessment s included change in post-void residual urine volume and adverse events . RESULTS From January 2012 through September 2013 a total of 94 patients were r and omized . Of these patients 76 completed the protocol treatment . In the full analysis set the change in total OABSS during the treatment period was significantly greater in the combination group than in the monotherapy group ( -2.21 vs -0.87 , p=0.012 ) . The changes in scores for urinary urgency , daytime frequency , International Prostate Symptom Score storage symptom subscore and quality of life index at 8 weeks were significantly greater in the combination group . The change in post-void residual urine volume was significantly greater in the combination group . Although 6 patients experienced adverse events in the combination group , urinary retention was observed in only 1 patient . CONCLUSIONS Combined tamsulosin and mirabegron treatment is effective and safe for patients with benign prostatic obstruction who have overactive bladder symptoms  after tamsulosin monotherapy
