Data from 12-week , r and omised , double-blind , placebo-controlled trials of tolterodine extended release ( ER ) , oxybutynin and solifenacin show that combined antimuscarinic+α-blocker treatment is generally more effective than monotherapy or placebo in men with OAB symptoms .
The efficacy and safety  of tolterodine ER+α-blocker treatment was not affected by prostate size or prostate-specific antigen ( PSA ) level .
In men meeting entry criteria for OAB and benign prostatic obstruction trials  , tolterodine ER alone was effective selectively in men with prostate size or PSA level below study medians .
Post hoc analyses from double-blind , placebo-controlled trials and prospect i ve studies of fesoterodine , oxybutynin , propiverine , solifenacin and tolterodine also suggest that antimuscarinics are generally safe and efficacious in men .
A retrospective data base study found that risk of AUR in men was the highest in the first month of treatment and decreased considerably thereafter .
Antimuscarinics , alone or with an α-blocker , appear to be efficacious and safe in many men with predominant OAB symptoms or persistent OAB symptoms despite α-blocker or 5-α-reductase inhibitor treatment .
Despite potential benefits , primary care clinicians may avoid using antimuscarinics in men with overactive bladder ( OAB ) symptoms because of safety concerns .
Tolterodine extended release attenuates lower urinary tract symptoms in men with benign prostatic hyperplasia.
PURPOSE In this open label , prospect i ve study we determined the efficacy and tolerability of tolterodine extended release ( ER ) in men with benign prostatic hyperplasia ( BPH ) and lower urinary tract symptoms ( LUTS ) in whom previous alpha-blocker therapy had failed . MATERIAL S AND METHODS A total of 43 consecutive men with BPH and LUTS in whom a mean of 5.7 months of alpha-blocker therapy had failed due to adverse events ( 11 ) or a lack of efficacy ( 32 ) received tolterodine ER ( 4 mg daily ) for 6 months . Primary efficacy end points were American Urological Association symptom score , and mean daytime and nighttime micturition frequency . Secondary end points were the peak urinary flow rate , post-void residual volume , the incidence of urinary retention , total score on the erectile function domain of the International Index of Erectile Function and adverse events . RESULTS A total of 39 men ( 91 % ) with a mean age of 61 years completed the 6-month trial .  Mean 24-hour micturition frequency decreased from 9.8 to 6.3 voids and nocturia decreased from 4.1 to 2.9 episodes nightly . Significant changes in mean American Urological Association symptom scores ( -6.1 ) , the peak urinary flow rate ( 1.9 ml per second ) and post-void residual volume ( -22 ml ) were also observed . Of the men 27 ( 63 % ) were potent at baseline and 29 ( 67 % ) were potent after 6 months of tolterodine ER treatment . Mean International Index of Erectile Function erectile function domain scores increased ( 6.9 ) . Four men ( 9 % ) discontinued therapy because of intolerable dry mouth . There were no reports of urinary retention . CONCLUSIONS Treatment with tolterodine ER in men with BPH and LUTS may be a reasonable therapeutic option as initial therapy or after failed treatment with alpha-blockers
