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 .
Urodynamic effects of the combination of tamsulosin and daily tadalafil in men with lower urinary tract symptoms secondary to benign prostatic hyperplasia: a randomized, placebo-controlled clinical trial
Objectives To evaluate the effect of association of tamsulosin/tadalafil taken daily compared with tamsulosin/placebo in the lower urinary tract with urodynamic study ( UDS ) . Methods All patients underwent baseline UDS before r and omization to tamsulosin 0.4 mg/tadalafil 5 mg ( Group 1 ; n = 20 ) or tamsulosin 0.4 mg/placebo ( Group 2 ; n = 20 ) once daily for 30 days . End-of- study UDS were performed on completion of the treatment period . The primary end point was to demonstrate changes in urodynamic variables in the voiding phase , detrusor pressure at maximum flow ( PdetQmax ) , and maximum flow rate ( Qmax ) , from baseline to week four . Results The primary outcome measure of this clinical trial , PdetQmax , showed a significant reduction in tamsulosin/tadalafil group ( 13 ± 17.0 ) compared to tamsulosin/placebo ( −1.2 ± 14.35 ) group ( P = 0.03 ) . Qmax increased in both groups , tamsulosin/tadalafil ( 1.0 ± 2.4 ) and tamsulosin/placebo ( 1.4 ± 2.4 ) , but the difference was not significant between treatment groups ( P = 0.65 ) . Total IPSS , storage , and voiding sub-score improved significantly in tamsulosin/tadalafil compared with tamsulosin/placebo group . Conclusions The association of tamsulosin/tadalafil reduces detrusor pressure at maximum flow without changing the maximum flow rate during micturition and significantly improves lower urinary tract symptoms compared with the isolated use of tamsulosin
