Based on improvement of mean International Prostate Symptom Score and quality of life scores , the effectiveness of the newer ABs was not different from the older ABs ( moderate strength of evidence [ SOE ] ) , but had more AEs ( low SOE ) .
Antimuscarinics/AB combination therapy had similar outcomes  as AB monotherapy ( all moderate SOE ) , but often had more AEs .
Phosphodiesterase type-5 inhibitors alone or in combination with ABs had similar or inferior outcomes than ABs alone .
Evidence was insufficient for the beta-3 adrenoceptor agonist .
For all newer agents , the evidence was generally insufficient to assess long-term efficacy , prevention of symptom progression , or AEs .
None of the drugs or drug combinations newly used to treat LUTS attributed to BPH showed outcomes superior to traditional AB treatment .
Given the lack of superior outcomes , the studies ' short time-horizon , and less assurance of their safety , their current value in treating LUTS attributable to BPH appears low .
We found none of the new drugs to be better but there was more concern about side effects
CONTEXT Alpha-blockers ( ABs ) and 5-alpha reductase inhibitors have an established role in treating male lower urinary tract symptoms ( LUTS ) attributed to benign prostatic hyperplasia ( BPH ) .
Recently , newer drugs have shown promise for this indication .
OBJECTIVE To assess the comparative effectiveness and adverse effects ( AEs ) of newer drugs to treat LUTS attributed to BPH through a systematic review and meta- analysis .
PATIENT SUMMARY In this paper , we review ed the evidence of newer drugs to treat men with urinary problems attributable to an enlarged prostate .
Sildenafil citrate and tamsulosin combination is not superior to monotherapy in treating lower urinary tract symptoms and erectile dysfunction
Purpose To evaluate the efficacy of sildenafil citrate only , 25 mg . Four times/week , tamsulosin only , 0.4 mg once daily , and the combination of both on lower urinary tract symptoms ( LUTS ) suggestive of benign prostate hyperplasia ( BPH ) and erectile dysfunction . Methods A total of 60 men with BPH-related LUTS were r and omized to receive sildenafil citrate only ( n = 20 ) , tamsulosin only ( n = 20 ) , and the combination of both ( n = 20 ) for 8 weeks . Changes from baseline in International Prostate Symptom Score ( IPSS ) , maximum urinary flow rate ( Qmax ) , post voiding residual urine volume ( PRV ) , Sexual Health Inventory for Male ( SHIM ) score , 3rd and 4th questions of International Index of Erectile Function ( IIEF ) were assessed at the end of the treatment . Results The mean age was 58 years .  IPSS , Qmax , PRV , SHIM scores , and 3rd and 4th questions in IIEF significantly improved in each group . Improvement of IPSS was more remarkable in combination ( 40.1 % ) and tamsulosin only ( 36.2 % ) groups in comparison with sildenafil citrate only group ( 28.2 % ; p < 0.001 ) . Improvement of Qmax and PRV were greater in tamsulosin only and combination than sildenafil citrate only group . SHIM scores significantly improved in sildenafil citrate only ( 65 % ) and combination ( 67.4 % ) than tamsulosin only ( 12.4 % ; p < 0.001 ) . Increases in the 3rd and 4th questions of IIEF were greater in sildenafil only and combination than tamsulosin only ( p < 0.001 ) . Conclusions Treatment with the combination of tamsulosin only and sildenafil citrate only was not superior to tamsulosin only to enhance voiding symptoms . Also , sexual function improvement was similar for both the combination and sildenafil citrate only treatments
