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 .
Combined tadalafil and α-blocker therapy for benign prostatic hyperplasia in patients with erectile dysfunction: a multicenter, prospective study.
This prospect i ve study evaluated the safety of tadalafil 5 mg taken once a day in terms of hypotensive side effects and whether it improves lower urinary tract symptoms ( LUTS ) and restores sexual function in patients with erectile dysfunction who are receiving concomitant α-blocker ( AB ) therapy for benign prostatic hyperplasia ( BPH ) . A total of 158 LUTS/BPH patients receiving AB therapy for ≥3 months were given tadalafil 5 mg once a day . Before treatment with tadalafil ( V1 ) , and 4 weeks ( V2 ) and 12 weeks ( V3 ) after starting  tadalafil , blood pressure , heart rate , International Prostate Symptom Score ( IPSS ) , maximal urine flow rate ( Qmax ) , postvoiding residual urine volume , and International Index of Erectile Function ( IIEF-5 ) score were measured . Of the 158 LUTS/BPH patients , a total of 119 completed the trial . Blood pressure ( systolic and diastolic ) and heart rate did not change . IPSS and IIEF-5 scores improved significantly , but Qmax and postvoiding residual urine volume did not ; however , in the 39 men with a low baseline Qmax ( ≤10 mL/s ) , Qmax rose significantly from 7.97 ± 1.44 mL/s ( baseline ) to 8.91 ± 1.60 mL/s ( V3 ; P = .012 ) . The remaining patients ( baseline Qmax > 10 mL/s ) did not change . At V2 and V3 , adverse side effects were observed in 10 men ( 7.30 % ) and 6 men ( 5.04 % ) , respectively . Facial flushing was the most common adverse side effect ( 6 men at V2 and 4 men at V3 ) , followed by headache ( 2 men each at V2 and V3 ) and dizziness ( 2 men at V2 ) . Two patients dropped out of the study because of adverse side effects . In conclusion , tadalafil 5 mg once a day in combination with AB appeared to have few adverse effects on hypotensive events and can improve LUTS and restore sexual function
