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 .
The long-term effect of doxazosin, finasteride, and combination therapy on the clinical progression of benign prostatic hyperplasia.
BACKGROUND Benign prostatic hyperplasia is commonly treated with alpha-adrenergic-receptor antagonists ( alpha-blockers ) or 5alpha-reductase inhibitors . The long-term effect of these drugs , singly or combined , on the risk of clinical progression is unknown . METHODS We conducted a long-term , double-blind trial ( mean follow-up , 4.5 years ) involving 3047 men to compare the effects of placebo , doxazosin , finasteride , and combination therapy on measures of the clinical progression of benign prostatic hyperplasia . RESULTS The risk of overall clinical progression -- defined as an increase above base line of at least 4 points in the American Urological Association symptom score , acute urinary retention , urinary incontinence , renal insufficiency , or recurrent urinary tract infection -- was significantly reduced by doxazosin ( 39 percent risk reduction , P<0.001 ) and finasteride ( 34 percent risk reduction , P=0.002 ) , as compared with placebo . The reduction in risk associated with combination therapy ( 66 percent for the comparison with placebo , P<0.001 ) was significantly greater than that associated with doxazosin ( P<0.001 ) or finasteride ( P<0.001 ) alone . The risks of acute urinary retention and the need for invasive therapy were significantly reduced by combination therapy ( P<0.001 ) and finasteride ( P<0.001 ) but not by doxazosin . Doxazosin ( P<0.001 ) , finasteride ( P=0.001 ) , and combination therapy ( P<0.001 ) each result ed in significant improvement in symptom scores , with combination therapy being superior to both doxazosin ( P=0.006 ) and finasteride ( P<0.001 ) alone . CONCLUSIONS Long-term combination therapy with doxazosin and finasteride was safe and reduced the risk of overall clinical progression of benign prostatic hyperplasia significantly more than did treatment with either drug alone . Combination therapy and finasteride alone reduced the long-term risk of acute urinary retention and the need for invasive therapy
