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 .
Efficacy and safety of the coadministration of tadalafil once daily with finasteride for 6 months in men with lower urinary tract symptoms and prostatic enlargement secondary to benign prostatic hyperplasia.
PURPOSE Medical treatment for men with lower urinary tract symptoms and prostatic enlargement secondary to benign prostatic hyperplasia is 5α-reductase inhibitor monotherapy or coadministration with an α-blocker . We assessed the effects of tadalafil 5 mg coadministered with finasteride 5 mg during 26 weeks on lower urinary tract symptoms and sexual symptoms . MATERIAL S AND METHODS In an international , r and omized , double-blind , parallel study of men 45 years old or older who were 5α-reductase inhibitor naïve and had an I-PSS ( International Prostate Symptom Score ) of 13 or greater and prostate volume 30 ml or greater , 350 were treated with placebo/finasteride  and 345 received tadalafil/finasteride for 26 weeks . Changes in lower urinary tract symptoms secondary to benign prostatic hyperplasia were assessed with the I-PSS , erectile dysfunction improvements were assessed with the IIEF-EF ( International Index of Erectile Function-Erectile Function ) in sexually active men and safety was assessed by evaluating adverse events . RESULTS Least squares mean changes from baseline in I-PSS after 4 , 12 and 26 weeks of tadalafil/finasteride coadministration were -4.0 , -5.2 and -5.5 , respectively . Corresponding values for placebo/finasteride coadministration were -2.3 , -3.8 and -4.5 ( p ≤ 0.022 at all visits favoring tadalafil/finasteride  coadministration ) . I-PSS subscores ( storage and voiding ) and quality of life index were also numerically improved with tadalafil/finasteride coadministration . Least squares mean changes from baseline in IIEF-EF  with tadalafil/finasteride coadministration were 3.7 after 4 weeks , and 4.7 after 12 and 26 weeks . Corresponding values for placebo/finasteride coadministration were -1.1 , 0.6 and -0.0 ( p < 0.001 at all visits favoring tadalafil/finasteride coadministration ) . Tadalafil/finasteride coadministration was well tolerated and most adverse events were mild/moderate . CONCLUSIONS The coadministration of tadalafil/finasteride provides early improvement in lower urinary tract symptoms in men with benign prostatic hyperplasia and prostatic enlargement . Tadalafil/finasteride coadministration also improves erectile function in men who have comorbid erectile dysfunction
