INTRODUCTION Benign prostatic hypertrophy ( BPH ) is a common disease whose frequency has risen throughout the world in concomitance with the increase in life expectancy . BPH causes voiding disturbances known by the acronym LUTS ( lower urinary tract symptoms ) , which heavily influence the quality of life in the elderly . The treatment for LUTS is mainly divided into medical and surgical , the latter usually represented by prostate ablation . Medical therapy includes synthetic molecules that interfere with the hormonal control of BPH or act on the bladder neck tonus , as well as natural remedies based on plant extracts from Serenoa Repens and /or Urtica Dioica . MATERIAL AND METHODS Two groups of patients who were c and i date s for surgery for BPH-induced LUTS , were r and omly recruited in a six-month trial aim ed at comparing outcome of treatment with a new combination of plants extracts ( Pluvio ® ) , which differs from the previous ones in that it also contains avocado and soya oil , as well as a high dose of Urtica Dioica , with no therapy . Age , IPSS score , maximal uroflow , prostate volume , PSA , free-to-total PSA ratio , post voiding residual urine and number of nocturia episodes were recorded and statistically evaluated using a NCSS 60 ® program . RESULT A marked benefit in terms of quality of life , measured by IPSS score , uroflow , residual urine and nocturia , was observed in the treated group compared to controls . PSA and prostate volume were not significantly affected . No noteworthy adverse events were observed . CONCLUSIONS The new phytotherapeutic combination evaluated in the present study would seem to be highly effective for the treatment of LUTS in BPH patients and does not have negative side effects . Its use could therefore be strongly advocated in this setting INTRODUCTION Serenoa repens ( saw palmetto ) has been employed for the treatment of lower urinary tract symptoms ( LUTS ) for several years . Its mechanism of action is believed to be due to anti and rogenic , antiproliferative and antinflammatory properties . An association of Serenoa with the nettle " Urtica dioica " showing antiproliferative activity and the pine " Pinus pinaster " derivative , showing antinflammatory action , has been proposed in recent years . Such an action is hoped to act not only by reducing LUTS but also by preventing the development of prostate cancer . MATERIAL AND METHODS During the years 2007 and 2008 , 320 patients suffering from LUTS were treated with an association of Serenoa repens 320 mg , Urtica dioica 120 mg and Pinus pinaster 5 mg , named IPBTRE . This treatment was administered to all patients for a minimal duration of 30 days to a maximum of a year , either alone or in association with antibiotics or alpha-blockers , if needed . Outcome analysis was based on evaluation of symptoms , prostate volume and maximum flow rate ( Qmax ) . RESULTS From a careful analysis of the data collected in our data base , the following observations can be made : ages varied between 19 and 78 years . The patients were affected by BPH in 46 % of cases , chronic prostatitis syndrome in 43 % , chronic genital-pelvic pain in 7 % and other conditions in 4 % , the absolute numbers being 147 , 138 , 22 and 7 patients , respectively . No untoward side effect was reported in any case . Variations in symptom score could be fully evaluated only in 80 of 320 patients ( 25 % ) , of whom 68 ( 85 % ) reported a significant benefit , with special reference to an improvement of pain , urgency , strangury and nocturia . Data on variations in prostate volume , as measured by digital rectal examination , were available in 84 ( 26.5 % ) patients . No significant change was observed . Qmax after treatment was measured in 83 ( 26 % ) patients . It did not show significant changes from the initial values . DISCUSSION The association tested in our study appeared to be safe and well tolerated . No changes in flow rate and prostate volume were observed , but a marked reduction of LUTS was observed in 85 % of evaluable cases , especially with regard to pain and irritative symptoms . Whether or not such an association may display a prevention of prostate cancer , may be investigated in additional studies Introduction Increasing attention has been focused on the use of phytotherapeutic agents to alleviate the symptoms of benign prostatic hyperplasia ( BPH ) in recent times . The best described and studied phytotherapeutic agent is Serenoa repens ( SR ) . Material s and methods This prospect i ve study was design ed to have 3 arms including SR 320 mg per day ( N = 20 ) , Tamsulosin ( TAM ) 0.4 mg per day ( N = 20 ) and SR + TAM ( N = 20 ) to reveal the superiority or equivalence between these treatment regimens in BPH . Results The groups were not statistically different with regard to increase in maximal urinary flow rate ( Qmax ) and decrease in International Prostate Symptom Score ( I-PSS ) ( P > 0.05 ) . No adverse effect was detected in SR therapy group . Conclusion Treatment of BPH by both SR and TAM seems to be effective alone . None of them had superiority to another and additionally , combined therapy ( SR + TAM ) does not provide extra benefits . Furthermore SR is a well-tolerated agent that can be used alternatively in the treatment of LUTS due to BPH Introduction : In Korea , increasing attention has recently been given to the use of phytotherapeutic agents to alleviate the symptoms of BPH . Serenoa repens has been shown to have an equivalent efficacy to Finasteride or Tamsulosin in the treatment of BPH in previous studies . The present study was design ed to compare the efficacy and safety of Serenoa repens plus tamsulosin with tamsulosin only over 12 months in men with LUTS secondary to BPH . Material s and Methods : One hundred forty men with symptomatic BPH ( IPSS ≥10 ) were recruited in our hospital for a 12-month , open-label , r and omized trial . Patients were r and omly assigned to either tamsulosin 0.2 mg/day plus Serenoa repens 320 mg/day ( n = 60 ) or tamsulosin 0.2 mg/day only ( n = 60 ) . Prostate volume and PSA were measured at baseline and at end-point , whereas total IPSS , and its storage and voiding subscores , LUTS-related QoL , Qmax , and PVR were evaluated at baseline and later every 6 months . Results : Total 103 patients were finally available : 50 in the TAM + SR group and 53 in the TAM group . At 12 months , total IPSS decreased by 5.8 with TAM + SR and 5.5 with TAM ( p = 0.693 ) ; the storage symptoms improved significantly more with TAM + SR ( -1.7 vs. -0.8 with TAM , p = 0.024 ) . This benefit with regard to storage symptom in the TAM + SR group lasts at 12 months ( -1.9 vs. -0.9 , p = 0.024 ) . The changes of voiding subscore , LUTS-related QoL , Qmax , PVR , PSA , and prostate volume showed no significant differences between the TAM + SR and TAM groups . During the treatment period , 8 patients ( 16.9 % ) with TAM and 10 ( 20 % ) with TAM + SR had drug-related adverse reactions , which included ejaculatory disorders , postural hypotension , dizziness , headache , gastro-intestinal disorders , rhinitis , fatigue and asthenia . Conclusions : The combination treatment of Serenoa repens and tamsulosin was shown to be more effective than tamsulosin monotherapy in reducing storage symptoms in BPH patients after 6 months and up to 12 months of treatment BACKGROUND / AIM It has been observed that a large number of patients with low urinary tract symptoms due to benign prostatic hyperplasia ( LUTS/BPH ) ) has been treated with a combination of tamsulosin ( TAM ) + Serenoa repens ( SR ) ( TAM + SR ) . The aim of this study was to compare a combination TAM + SR with TAM and SR alone , to see if there was any difference in efficacy and tolerance of each in patients with LUTS/BPH . METHODS In this prospect i ve study patients had to have prostate volume ( PV ) < 50 mL , International Prostate Symptom Score ( IPSS ) of 7 - 18 , Quality of Life score ( QoLs ) > 3 , a maximal flow rate ( Qmax ) of 5 - 15 mL/s , with post voiding residual volume ( PVR ) < 150 mL and serum prostatic antigen ( PSA ) < 4 ng/mL.  TAM ( 0.4 mg ) was administered once a day , SR ( 320 mg ) daily or SR ( 320 mg ) + TAM ( 0.4 mg ) daily for a median period of 6 months . RESULTS A total of 297 patients were recruited , whereas 265 patients were fully available : 87 into the group TAM , 97 into the group SR and 81 into the group TAM + SR .  There was no statistically significant difference between the treatment groups in the sense of demographic and other baseline parameters . No difference was found among the 3 treatment groups , neither in the major endpoint of the study in the sense of a change between baseline and final evaluation in total IPSS , obstructive and irritative subscores , improvement of QoLs , increase in Qmax , nor for the second endpoint including diminution of PV , PSA and PVR . During the treatment period 20 ( 23 % ) of the patients managed with TAM and 17 ( 21 % ) with TAM + SR had drug- treated with related adverse reactions . No adverse effect was detected in the group SR . CONCLUSION Treatment of BPH by both SR and TAM seems to be efficacious alone . None of them had superiority over another and , additionally , a combined therapy ( TAM + SR ) does not provide extra benefits . Furthermore , SR is a well-tolerated agent that can be used alternatively in the treatment of LUTS/BPH BACKGROUND Phytotherapy has been used to treat patients with lower urinary tract symptoms ( LUTS ) . We evaluated the efficacy and tolerability of combination therapy between Serenoa Repens ( SeR ) , Lycopene ( Ly ) , and Selenium ( Se ) + tamsulosin versus single therapies . METHODS PROCOMB trial ( IS RCT N78639965 ) was a r and omized double-blinded , double-dummy multicenter study of 225 patients between 55 and 80 years old , PSA ≤ 4 ng/ml , IPSS ≥12 , prostate volume ≤60 cc , Qmax ≤15 ml/sec , postvoid residual urine ( PVR ) < 150 ml . Participants were r and omized group A ( SeR-Se-Ly ) , group B ( tamsulosin 0.4 mg ) , group C ( SeR-Se-Ly + tamsulosin 0.4 mg ) . The primary endpoints of the study were the reduction of IPSS , PVR , and increase of Qmax in group C versus monotherapy groups . RESULTS The decrease for combination therapy was significantly greater versus group A ( P < 0.05 ) and group B ( P < 0.01 ) for IPSS and versus group A ( P < 0.01 ) for PVR from baseline to 6 months . A greater decrease in IPSS was observed for Group C versus group A ( P < 0.01 ) and increase in Qmax versus group B ( P < 0.01 ) , from 6 months to 12 months . At one year , the changes of IPSS and Qmax were greater for Group C versus monotherapies ( each comparison < 0.05 ) . The proportions of men with a decrease of at least three points ( each comparison P < 0.05 ) and decrease of 25 % for IPSS ( each comparison P < 0.01 ) were greater for Group C. CONCLUSION SeR-Se-Ly + tamsulosin therapy is more effective than single therapies in improving IPSS and increasing Qmax in patients with LUTS OBJECTIVES To assess the effects of saw palmetto on voiding symptoms and urodynamic parameters in men with lower urinary tract symptoms ( LUTS ) presumed secondary to benign prostatic hyperplasia ( BPH ) . METHODS Fifty men with previously untreated LUTS and a minimum International Prostate Symptom Score ( IPSS ) of 10 or greater were treated with a commercially available form of saw palmetto ( 160 mg twice per day ) for 6 months . The initial evaluation included measurement of peak urinary flow rate , postvoid residual urine volume , pressure-flow study , and serum prostate-specific antigen ( PSA ) level . Patients completed an IPSS , serum PSA was determined , and flow rate was measured every 2 months during the course of the study . A urodynamic evaluation was repeated at the completion of the 6-month trial . RESULTS The mean IPSS ( + /-SD ) improved from 19.5+/-5.5 to 12.5+/-7.0 ( P < 0.001 ) among the 46 men who completed the study . Significant improvement in the symptom score was noted after treatment with saw palmetto for 2 months . An improvement in symptom score of 50 % or greater after treatment with saw palmetto for 2 , 4 , and 6 months was noted in 21 % ( 10 of 48 ) , 30 % ( 14 of 47 ) , and 46 % ( 21 of 46 ) of patients , respectively . There was no significant change in peak urinary flow rate , postvoid residual urine volume , or detrusor pressure at peak flow among patients completing the study . No significant change in mean serum PSA level was noted . CONCLUSIONS Saw palmetto is a well-tolerated agent that may significantly improve lower urinary tract symptoms in men with BPH . However , we were unable to demonstrate any significant improvement in objective measures of bladder outlet obstruction . Placebo-controlled trials of saw palmetto are needed to evaluate the true effectiveness of this compound Background Chronic prostatic inflammation ( CPI ) could be a cause of symptomatic or complicated benign prostatic hyperplasia ( BPH ) . In previous in vitro and in vivo studies , Hexanic Extract of Serenoa repens ( HESr ) namely Permixon ® has demonstrated potent anti‐inflammatory properties . With the aim to provide new insight onto HESr anti‐inflammatory properties in human we explore its effect on CPI biomarkers in men with lower urinary tract symptoms ( LUTS ) related to BPH using a non‐invasive method and investigate links between biomarkers and clinical symptoms . Methods An international , r and omized , double‐blind , parallel‐group , tamsulosin‐controlled study was carried out in 206 men with BPH‐related LUTS . Patients received oral daily HESr 320 mg or tamsulosin 0.4 mg during 3 months . The first urine stream after digital rectal examination ( DRE ) was collected at Day 1 and Day 90 and mRNA was extracted from prostatic epithelial cells desquaming in the lumen of the gl and s and seminal plasma fluid after DRE . mRNA quantification of the 29 most significant published inflammation markers in BPH and protein detection in urine was performed . Results At D90 , a decrease in mean gene expression was observed for 65.4 % of the markers detected in the HESr group versus 46.2 % in the tamsulosin group . In the 15 most frequently expressed genes , this difference was higher ( 80 % vs. 33 % respectively ) . Three proteins ( MCP‐1/CCL2 , IP‐10/CXCL10 , and MIF ) were detected . At D90 , a decrease in the number of patients who expressed MCP‐1/CCL2 and IP‐10/CXCL10 was observed only in the HESr group . Moreover , MIF expression was significantly reduced by HESr compared with tamsulosin ( P = 0.007 ) . Finally , in contrast to tamsulosin , the subgroup of patients treated by HESr and who over expressed MIF at baseline , had a higher response to the International Prostate Symptom Score ( I‐PSS ) than those who did not over express this protein ( mean I‐PSS change : −6.4 vs. −4.5 respectively ) . As the study is exploratory , results should be confirmed in a powered clinical study . Conclusions These results showed for the first time at clinical level the anti‐inflammatory properties of HESr , already indicated in BPH‐related LUTS . Thus , HESr could be of interest to prevent unfavourable evolution in patients with CPI . Prostate 75:1857–1867 , 2015 . © 2015 The Authors . The Prostate Published by Wiley Periodicals , OBJECTIVE To compare the efficacy of the lipido-sterolic extract of Serenoa repens , Permixon , to that of the alpha-blocker , tamsulosin , in the treatment of severe low urinary tract symptoms ( LUTS ) of benign prostatic hyperplasia ( BPH ) . METHODS In a 12-month , double-blind , r and omized study that showed equivalent efficacy of Permixon 320 mg/day and tamsulosin 0.4 mg/day ( " PERMAL study ") , 685 BPH patients with IPSS > or = 10 had been analyzed for efficacy . Of these , the 124 patients with severe LUTS ( IPSS > 19 ) at r and omization were retained for this subset analysis . After a 4-week run-in period , 59 and 65 patients had been r and omized to tamsulosin and Permixon groups , respectively . Both treatment groups were compared regarding the evolution from baseline of total IPSS and its irritative and obstructive subscores , LUTS-related QoL , prostate volume , Q(max ) and MSF-4 ( sexual activity question naire ) at different time points over 1 year . An analysis of variance of changes from baseline to end point was performed for all the parameters . The over-time evolutions of total , irritative and obstructive IPSS were further compared using a variance analysis for repeated measurements . RESULTS At 12 months , total IPSS decreased by 7.8 with Permixon and 5.8 with tamsulosin ( p=0.051 ) ; the irritative symptoms improved significantly more ( p=0.049 ) with Permixon ( -2.9 versus -1.9 with tamsulosin ) . The superiority of Permixon in reducing irritative symptoms appeared as soon as month 3 and was maintained up to month 12 ( p=0.03 ) . CONCLUSION Permixon 320 mg/day was shown to be slightly superior to tamsulosin 0.4 mg/day in reducing LUTS in severe BPH patients after 3 months and up to 12 months of treatment To compare in a r and omised , open‐label , non‐inferiority clinical study , the efficacy and tolerability  of Serenoa repens ( SeR ) + selenium ( Se ) + lycopene ( Ly ) ( SeR‐Se‐Ly ) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms ( LUTS ) OBJECTIVE To evaluate the efficacy of Profluss ® on prostatic chronic inflammation ( PCI ) . MATERIAL S AND METHODS We prospect ively enrolled 168 subjects affected by LUTS due to bladder outlet obstruction su bmi tted to 12 cores prostatic biopsy for suspected prostate cancer + 2 cores collected for PCI valuation . First group consisted of 108 subjects , with histological diagnosis of PCI associated with BPH and high grade PIN and /or ASAP , r and omly assigned to 1:1 ratio to  daily Profluss ®  ( group I ) for 6 months or to control group ( group Ic ) . Second group consisted of 60 subjects , with histological diagnosis of BPH , r and omly assigned to 1:1 ratio to daily Profluss ® + a-blockers treatment ( group II ) for 3 months or to control group ( group IIc ) . After 6 months first group underwent 24 cores prostatic re-biopsy + 2 cores for PCI while after 3 months second group underwent two-cores prostatic for PCI . Specimens were evaluated for changes in inflammation parameters and for density of T-cells ( CD3 , CD8 ) , B-cells ( CD20 ) and macrophages ( CD68 ) . RESULTS At follow-up there were statistical significant reductions of extension and grading of flogosis , mean values of CD20 , CD3 , CD68 and mean PSA value in group I compared to Ic , while extension and grading of flogosis in group II were inferior to IIc but not statistical significant . A statistically significant reduction in the density of CD20 , CD3 , CD68 , CD8 was demonstrated in group II in respect to control IIc . CONCLUSIONS Serenoa repens+Selenium+Lycopene may have an anti-inflammatory activity that could be of interest in the treatment of PCI in BPH and /or PIN/ASAP patients Background The primary objectives of the treatment for the  lower urinary tract symptoms ( LUTS ) associated with benign prostatic hyperplasia ( BPH ) are to produce rapid , sustained , and safe improvements in the symptoms that affect the quality of life in the majority of men over 50 . In this study , we evaluated the efficacy and safety of the combined therapy with terazosin ( & agr;1‐adrenergic receptor antagonist ) and tolterodine ( anticholinergic agent ) for LUTS associated with BPH . Methods This combination study included 69 patients diagnosed with LUTS associated with BPH based on the International Prostate Symptom Scores ( IPSS ) , urinary flow rate , prostate volume , urinary residual , and their serum prostate‐specific antigen levels .  Initially , 191 patients were treated with terazosin 2 mg once daily for one week . Those patients with continued LUTS after the initial treatment were allocated r and omly into two groups : terazosin group ( n=36 ) in which patients were treated with terazosin 2 mg once daily for six weeks , and combination group ( n=33 ) in which patients were treated with both terazosin 2 mg once daily and tolterodine 2 mg twice daily for 6 weeks . Results The IPSS were significantly improved in both groups after treatment , and the reduction of IPSS in the combination group was significantly greater than that in the terazosin group ( P<0.01 ) . A decrease in urgency , frequency and nocturia were the main contributory factors causing the reduction of IPSS in the combination group . The differences about the peak urinary flow rate and the residual urine from the baseline values were noted in both groups after treatment , but were not significant between the two groups . The incidence of adverse effects in the combination group was higher than that in the terazosin group . As expected the most common adverse effect was mouth dryness which was associated with anticholinergic drugs such as tolterodine . Conclusions Patients with LUTS associated BPH appear the improved IPSS after combined therapy with terazosin and tolterodine . This study , although short term and limited numbers of patients , provides evidence that the combined therapy with terazosin plus tolterodine is a good approach for meeting the objectives of rapid , sustained , and safe improvements in the LUTS associated with BPH . And the profile of patients in this study might be used as the indication of such combined therapy for LUTS associated with BPH without urodynamic evaluation OBJECTIVES Sixty-three patients suffering from benign prostatic hyperplasia ( BPH ) entered a double-blind , comparative , parallel-groups study lasting 3 weeks , carried out to compare the efficacy and safety of alfuzosin 2.5 mg tid ( n = 32 ) vs serenoa repens 160 mg bid ( n = 31 ) in BPH . METHODS Efficacy was assessed both on clinical symptoms ( Boyarsky 's scale , visual analogue scale , clinical global impression ) , urinary flow rates ( uroflowmetry ) and residual urinary volume ( transabdominal ultrasound ) . Events and reported signs were recorded throughout the entire study . RESULTS Statistically significant and clinical ly relevant differences were found between the two treatments in favour of alfuzosin for Boyarsky 's total score ( decrease from 9.6 + /- 3.0 to 5.9 + /- 3.0 , 38.8 % for alfuzosin and from 9.3 + /- 2.5 to 6.8 + /- 2.8 , 26.9 % for serenoa repens ) and obstructive score ( decrease from 4.9 + /- 2.1 to 3.0 + /- 1.9 , 37.8 % for alfuzosin ; from 4.4 + /- 1.7 to 3.4 + /- 1.8 , 23.1 % for Serenoa repens ; p = 0.01 for both ) . Clinical ly relevant differences were found between the two treatments for visual analogue scale and overall clinical impression at the end of the study . Furthermore , the increase in quality of micturition was better with alfuzosin . The proportion of responders ( increase on day 21 in peak flow rate of at least 25 % relative to the baseline values ) was in favour of alfuzosin ( 71.8 % and 48.4 % for alfuzosin and Serenoa repens , respectively ; p = 0.057 ) . Both treatments were well tolerated . No patient treated with alfuzosin complained of any adverse event at any time during the study . One patient in the Serenoa group complained of mild pruritus which cleared spontaneously . Systolic , diastolic blood pressure and heart rate did not show any clinical ly relevant change during treatment with alfuzosin . CONCLUSIONS The findings confirm the efficacy and safety of alfuzosin in symptomatic BPH and indicate the superiority of alfuzosin over Serenoa repens in the treatment of urinary signs and symptoms of BPH BACKGROUND Tadalafil improved lower urinary tract symptoms ( LUTS ) suggestive of benign prostatic hyperplasia ( BPH ; LUTS/BPH ) in clinical studies but has not been evaluated together with an active control in an international clinical study . OBJECTIVE Assess tadalafil or tamsulosin versus placebo for LUTS/BPH . DESIGN , SETTING , AND PARTICIPANTS A r and omised , double-blind , international , placebo-controlled , parallel-group study assessed men ≥45 yr of age with LUTS/BPH , International Prostate Symptom Score ( IPSS ) ≥13 , and maximum urinary flow rate ( Q(max ) ) ≥4 to ≤15ml/s . Following screening and washout , if needed , subjects completed a 4-wk placebo run-in before r and omisation to placebo ( n=172 ) , tadalafil 5 mg ( n=171 ) , or tamsulosin 0.4 mg ( n=168 ) once daily for 12 wk . MEASUREMENTS Outcomes were assessed using analysis of covariance ( ANCOVA ) or ranked analysis of variance ( ANOVA ) ( continuous variables ) and Cochran-Mantel-Haenszel test or Fisher exact test ( categorical variables ) . RESULTS AND LIMITATIONS IPSS significantly improved versus placebo through 12 wk with tadalafil ( -2.1 ; p=0.001 ; primary efficacy outcome ) and tamsulosin ( -1.5 ; p=0.023 ) and as early as 1 wk ( tadalafil and tamsulosin both -1.5 ; p<0.01 ) . BPH Impact Index significantly improved versus placebo at first assessment ( week 4 ) with tadalafil ( -0.8 ; p<0.001 ) and tamsulosin ( -0.9 ; p<0.001 ) and through 12 wk ( tadalafil -0.8 , p=0.003 ; tamsulosin -0.6 , p=0.026 ) . The IPSS Quality -of-Life Index and the Treatment Satisfaction Scale-BPH improved significantly versus placebo with tadalafil ( both p<0.05 ) but not with tamsulosin ( both p>0.1 ) . The International Index of Erectile Function-Erectile Function domain improved versus placebo with tadalafil ( 4.0 ; p<0.001 ) but not tamsulosin ( -0.4 ; p=0.699 ) . Q(max ) increased significantly versus placebo with both tadalafil ( 2.4ml/s ; p=0.009 ) and tamsulosin ( 2.2ml/s ; p=0.014 ) . Adverse event profiles were consistent with previous reports . This study was limited in not being powered to directly compare tadalafil versus tamsulosin . CONCLUSIONS Monotherapy with tadalafil or tamsulosin result ed in significant and numerically similar improvements versus placebo in LUTS/BPH and Q(max ) . However , only tadalafil improved erectile dysfunction . TRIAL REGISTRATION Clinical trials.gov ID NCT00970632 Permixon , the lipidosterolic extract of Serenoa repens , is widely used for the treatment of symptoms associated with benign prostatic hyperplasia ( BPH ) . This open study assessed the efficacy and tolerability of Permixon 160 mg twice daily administered for 2 years . One hundred fifty-five men with clinical ly diagnosed BPH and complaints of prostatic symptoms were enrolled in the study . At 6 , 12 , 18 , and 24 months , the International Prostate Symptom Score ( I-PSS ) , quality of life , and sexual function score were recorded , and urodynamics and biologic values were measured . Adverse events were recorded every 3 months . I-PSS and quality of life improved significantly from baseline at each evaluation time point . At the end of the study and at each evaluation , maximum urinary flow also improved significantly . Prostate size decreased . Sexual function remained stable during the first year of treatment and significantly improved ( P = .001 ) during the second year . Prostate-specific antigen was not affected , and no changes in plasma hormone levels were observed . Nine patients reported 10  adverse events  , none related to treatment . Improvements in efficacy parameters began at 6 months and were maintained up to 24 months . These data demonstrate the long-term efficacy and tolerability of Permixon and support its use as a first-line medical therapy for uncomplicated symptomatic BPH
S. repens is safe in its application .
We suggest that strong placebo effect , potentially influenced by positive patients ' expectation on S. repens , shapes both the clinical practice outcomes and the findings of clinical trials .
Hitherto , the totality of evidence continues to suggest that S. repens is a prudent therapeutic option as part of the naturopathic treatment for LUTS/BPH .
OBJECTIVES Benign prostatic hyperplasia ( BPH ) commonly affects men above 40 years old .
The progression of BPH is often accompanied with lower urinary tract symptoms ( LUTS ) that can significantly affect the quality of life of the patients .
Serenoa repens ( saw palmetto ) is a popular herbal remedy indicated for LUTS/BPH .
We review ed the current research on the efficacy of S. repens on LUTS/BPH as a monotherapy as well as combination therapies .
RESULTS The latest evidence , based largely on the Cochrane review , suggests that S. repens is not superior to placebo in treating LUTS/BPH as a monotherapy , even at double and triple doses .
Initial clinical trials on treatment of LUTS/BPH using S. repens with lycopene and selenium , as well as S. repens with Urtica Dioica , have shown positive results .
