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 comparative randomized prospective study to evaluate efficacy and safety of combination of tamsulosin and tadalafil vs. tamsulosin or tadalafil alone in patients with lower urinary tract symptoms due to benign prostatic hyperplasia.
INTRODUCTION Lower urinary tract symptoms ( LUTS ) associated with benign prostatic hyperplasia ( BPH ) and erectile dysfunction are common disorders of advancing age . AIM To evaluate the efficacy and safety of tamsulosin and tadalafil in patients with LUTS due to BPH . METHODS In this prospect i ve r and omized study , 133 men complaining of LUTS due to BPH were included . Forty-five patients received tamsulosin 0.4 mg/day alone ( Group A ) , 44 patients received tadalafil 10 mg/day ( Group B ) , and combination therapy ( tamsulosin and tadalafil both ) was instituted in 44 patients ( Group C ) . After a 2-week medication free run-in period , they were evaluated for International Prostatic Symptom Score ( IPSS ) , International Index of Erectile Function score ( IIEF5 ) , quality of life ( IPSS QoL ) , maximum urinary flow rate ( Qmax ) , post-void residual urine ( PVR ) volume , and safety parameters before and at 3 months of treatment . MAIN OUTCOME MEASURES There were primary ( IPSS , IPSS QoL index , Qmax , and PVR ) and secondary ( erectile function [ EF ] domain scores from IIEF5 ) efficacy end points . Safety assessment included laboratory tests and patient 's reporting of adverse event . RESULTS A significant improvement in IPSS score was observed in all the 3 groups A , B , and C ( -50.90 % , P < 0.05 ; -33.50 % , P < 0.05 ; and -53.90 % , P < 0.05 , respectively ) . IIEF5 score increased significantly in these three groups ( + 39.28 % , P < 0.05 ; + 45.96 % , P < 0.05 ; and + 60.23 % , P < 0.05 , respectively ) . A significant increase in Qmax and decrease in PVR were also observed ( 33.99 % , P < 0.05 ; 29.78 % , P < 0.05 ; and 37.04 % , P < 0.05 ) and ( -60.90 % , P < 0.05 ; -49.45 % , P < 0.05 ; and -62.97 % , P < 0.05 , respectively ) . The QoL scores improved significantly ( -73.35 % , P < 0.05 ; -70.26 % , P < 0.05 ; and -79.65 % , P < 0.05 , respectively ) . Side effects were dyspepsia , heartburn , headache , flushing , myalgia , and backache . Adverse effect dropout was 3.7 % . No participant experienced any severe or serious adverse events . CONCLUSIONS In patients with LUTS due to BPH , tamsulosin and tadalafil alone or in combination cause a significant improvement in patients with LUTS . Their EF also improves with these medications . The improvement is better with combination therapy compared with single agent alone
