This combination seems to be more efficacious in terms of several outcome variables in patients whose prostate volume is between 30 ml and 40 ml when treatment is maintained for > 1 yr ; when given for < 1 yr , α1-blockers alone are just as effective .
The combination of α1-blocker/5-ARI shows a slightly increased rate of adverse events .
It remains unknown whether its safety and superiority over either drug as monotherapy are sustained after > 6 yr .
The α1-blocker/muscarinic receptor antagonist ( antimuscarinic ) combination was most frequently assessed as an add-on therapy to already existing α1-blocker therapy .
Inconsistent data derive from heterogeneous study population s and different study design s. Currently , the α1-blocker/antimuscarinic combination appears to be a second-line add-on for patients with insufficient symptom relief after monotherapy .
The combination seems to be safe in men with postvoid residual < 200 ml .
The α1-blocker/phosphodiesterase type 5 inhibitor combination is a new treatment option with only preliminary reports .
CONCLUSIONS An α1-blocker/5-ARI combination is beneficial for patients whose prostate volume is between 30 ml and 40 ml when medical treatment is intended for > 1 yr .
Based on short-term follow-up studies , add-on of antimuscarinics to α1-blockers is an option when postvoid residual is < 200 ml
BACKGROUND Several drugs are approved for the treatment of lower urinary tract symptoms ( LUTS ) in men , but these are mostly used by clinicians as monotherapies .
The combination of different compounds , each of which targets a different aspect of LUTS , seems appealing .
However , only few clinical trials have evaluated the effects of combination therapies .
OBJECTIVE This systematic review analyzes the efficacy and adverse events of combination therapies for male LUTS .
Efficacy and tolerability of doxazosin and finasteride, alone or in combination, in treatment of symptomatic benign prostatic hyperplasia: the Prospective European Doxazosin and Combination Therapy (PREDICT) trial.
OBJECTIVES To evaluate the efficacy and tolerability of the selective alpha(1)-adrenergic antagonist doxazosin and the 5-alpha-reductase inhibitor finasteride , alone and in combination , for the symptomatic treatment of benign prostatic hyperplasia . METHODS In a prospect i ve , double-blind , placebo-controlled trial , 1095 men aged 50 to 80 years were r and omized to treatment for 52 weeks with doxazosin , finasteride , the combination of doxazosin and finasteride , or placebo . The dose of finasteride ( or its matched placebo ) was 5 mg/day . Doxazosin ( or its matched placebo ) was initiated at 1 mg/day , and titrated up to a maximum of 8 mg/day over approximately 10 weeks according to the response of the maximal urinary flow rate ( Qmax ) and International Prostate Symptom Score ( IPSS ) . The IPSS and Qmax were assessed at baseline and at weeks 10 , 14 , 26 , 39 , and 52 or at the endpoint . RESULTS An intent-to-treat analysis of 1007 men showed doxazosin and doxazosin plus finasteride combination therapy produced statistically significant improvements in total IPSS and Qmax compared with placebo and finasteride alone ( P < 0.05 ) . Finasteride alone was not significantly different statistically from placebo with respect to total IPSS and Qmax . All treatments were generally well tolerated . CONCLUSIONS Doxazosin was effective in improving urinary symptoms and urinary flow rate in men with benign prostatic hyperplasia , and was more effective than finasteride alone or placebo . The addition of finasteride did not provide further benefit to that achieved with doxazosin alone
