Pooled data analyses revealed that tadalafil 5 mg once daily allows the clinical ly-meaningful improvement of LUTS and nocturnal voiding frequency independent of both erectile dysfunction severity and improvement .
PDE5-Is are safe and effective in improving both LUTS and erectile function in appropriately selected men with LUTS/BPE .
We found evidence to confirm that phosphodiesterase type 5 inhibitors are a valid treatment option for men affected by bothersome urinary symptoms with or without erectile dysfunction
CONTEXT Several pre clinical reports , r and omized controlled trials , systematic review s , and posthoc analyses corroborate the role of phosphodiesterase type 5 inhibitors ( PDE5-Is ) in the treatment of men with lower urinary tract symptoms ( LUTS ) associated with benign prostatic enlargement ( BPE ) .
OBJECTIVE Up date of the latest evidence on the mechanisms of action , evaluate the current meta-analyses , and emphasize the results of pooled data analyses of PDE5-Is in LUTS/BPE .
PATIENT SUMMARY We review ed recent literature on phosphodiesterase type 5 inhibitors in men with lower urinary tract symptoms associated with prostatic enlargement .
Effects of tadalafil on nighttime voiding (nocturia) in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia: a post hoc analysis of pooled data from four randomized, placebo-controlled clinical studies
Purpose The phosphodiesterase type 5 inhibitor tadalafil is approved for the treatment of signs and symptoms of benign prostatic hyperplasia ( BPH ) . While tadalafil significantly improves overall lower urinary tract symptoms suggestive of BPH ( LUTS/BPH ) , improvements in nocturia were not significant in individual studies . We therefore sought to further assess nocturia based on data integrated from four tadalafil registration al studies . Methods Data were integrated from four r and omized , placebo-controlled  , double-blind , 12-week registration al studies of tadalafil for LUTS/BPH . Nocturia was assessed as nighttime voiding frequency using the International Prostate Symptom Score question 7 ( IPSS Q7 ) . Efficacy results were analyzed using analysis of covariance . Results For the tadalafil 5 mg once daily ( N = 752 ) and placebo ( N = 748 ) groups , baseline characteristics were well balanced , and the overall severity of nocturia per mean IPSS Q7 was 2.3 ± 1.2 . The mean treatment change was −0.4 with placebo and −0.5 with tadalafil ; the least-squares mean ( st and ard error ) treatment difference was −0.2 ( 0.05 ) , p = 0.002 . For patients receiving placebo and tadalafil , respectively , the proportion with improved nocturnal frequency was 41.3 and 47.5 % , with no change was 44.8 and 41.0 % , and with worsening was 13.9 and 11.5 % . Conclusions A statistically significant improvement in nocturnal frequency was seen with tadalafil over placebo ; however , the treatment difference was small and not considered clinical ly meaningful . Further studies using voiding diaries and excluding patients with nocturnal polyuria would be needed to more precisely estimate the impact of tadalafil on nocturia associated with LUTS/BPH
Pooled data analyses revealed that tadalafil 5 mg once daily allows the clinical ly-meaningful improvement of LUTS and nocturnal voiding frequency independent of both erectile dysfunction severity and improvement .
