Kaplan found no significant difference for men with small prostates. Labasky R, Afridi SK, You can take your dose with or without food. There were changes at years 1 and 4 of 1.8 and 2.2 mL/s, respectively, for finasteride, and 1.3 and 1.4 mL/s, respectively, for placebo. At 48 weeks in the PRO 160/120 arm, men with prostates 40 mL and > 40 mL had improved flows of 1.6 and 2.1 mL, respectively. Lieber M, Secondary analysis to included trial Gormley 1992. Review of Gormley 1992 and Finasteride Study Group 1993. We noted all trials not using an intentiontotreat analysis (ITT), but conducted our analysis by this principal. Kusek JW, Lepor 1998 (Lepor 1996) reported mean changes in the AUA total score by men with baseline prostate sizes of: For men with small prostates, terazosin significantly improved urine flows versus finasteride. He armed himself with a balaclava, latex gloves, condoms and Viagra pills and posed as a cab driver in a Mercedes to roam the streets of Brighton, East Sussex. et al. What's the typical finasteride dosage for adults? For male pattern hair loss in men, the typical finasteride dosage is 1 mg by mouth once daily. The goal of treatment is to reduce bothersome and irritative urinary symptoms that negatively affect quality of life (QoL). Data was extracted into Microsoft Excel spreadsheets and reviewed by JT and RM. Contact person's contact details updated and author affiliations aligned. For adverse effects mostly associated with finasteride, there was no difference for 'decreased libido' (RR 1.36, 95% CI 0.65 to 2.84) or 'impotence' (RR 1.91, 95% CI 0.81 to 4.46) versus Permixon, and for 'withdrawals due to adverse events', the comparison favored finasteride (RR 0.51, 95% CI 0.27 to 0.95). The absolute risk of surgery was non significant (Analysis 1.4). Our primary outcome was change in a validated, urinary symptomscale score, such as the AUA/IPSS. Longterm 6year experience with finasteride in patients with benign prostatic hyperplasia. To see if longterm change in PSA, as a surrogate endpoint, was affected by the active intervention, MTOPS compared finasteride to placebo (McConnell 2003). For men with small (< 25 mL), medium (25 to < 40 mL), and large ( 40 mL) prostates, finasteride modestly decreased the absolute risk of progression ( 4 point increase). Wessells H. The relationship among lower urinary tract symptoms, prostate specific antigen and erectile dysfunction in men with benign prostatic hyperplasia: results from the PROSCAR longterm efficacy and safety study. Withdrawal of treatment leads to reversal of effect within 12 months. Finasteride in the treatment of benign prostatic hyperplasia. 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, Comparison of tamsulosin and finasteride for lower urinary tract symptoms associated with benign prostatic hyperplasia in Korean patients, The Journal of International Medical Research. Ninetyone per cent of the trials (21/23) were described as blinded. Comparing shortterm (6 to 12 months) to longterm (> 1 year) therapy, MTOPS reported no difference in median improvements of the AUASI at 1 year, but a median significant difference at 4 years. Urtica dioica is a herbaceous, flowering perennial found on most of Earth. . Garris JB, Andriole, Combination therapy reduced the absolute risk of progression 4% (McConnell 2003) (RD 0.04, 95% CI 0.06 to 0.01). Doxazosin decreased the absolute risk for surgical intervention by 1%. Kaplan SA, et al. Combination therapy significantly improved symptoms versus monotherapy, and was clinically significant ( 4 point decrease in the AUASI/IPSS) as well. The intercurrent comparison was significant at 6 and 26 weeks, and favored Permixon. Finasteride is a prescription medication. At 1 year the finasteride (n = 496) and placebo arms (n = 459) were not significantly different. et al. . There was no difference in the endpoint comparison (MD 0.70, 95% CI 0.14 to 1.54). For men with prostates > 40 mL (n = 202), endpoints were 5.6 and 6.3 points, and not significantly different as well (MD 0.70, 95% CI 1.96 to 0.56). And for men with two or more incidents, mean changes were 0.79 and 0.68 and for combination therapy (n = 393) and finasteride (n = 385), respectively. For men with medium (25 mL to < 40 mL) and large ( 40 mL) prostates at baseline, combination therapy significantly improved symptom scores, lowered the risk of surgical intervention, and decreased the risk of progression ( 4 point increase), versus doxazosin alone. Bayraktar Y. Pharmacotherapy of benign prostatic hyperplasia: inhibitor of 5 Alphareductase. We compared adverse effects events that were possibly causal by the active drug that were generally associated with each. Two small trials reported no difference in urinary symptom scores between finasteride and tamsulosin. I would also like to sign up for a free GoodRx account, Written by Brian Leonard, PharmD, BCACP, BCGP, Written by Alina Goldenberg, MD, MAS, FAAD, Written by Ross Phan, PharmD, BCACP, BCGP, BCPS. By years 2, 3, and 4, only "decreased ejaculate volume" was significantly different, favoring placebo (P < 0.05). For men with small, medium, and large prostates, terazosin significantly improved AUA scores versus finasteride. McConnell JD, Of those, and from subsequent handsearching, we identified 51 possible RCTs. A 3armed trial using Boyarsky II (range 0 to 36), Gormley 1992 compared 1 mg finasteride (as well as 5 mg finasteride) to placebo. McConnell 2003, reporting outcomes for the AUASI (but not variances) at years 1 and 4, found median improvements of 4.0 and 5.0 points, respectively, for finasteride, and 4.0 and 4.0 points, respectively, for placebo. For men 70 years old or older, there were mean changes of 0.29 and 0.08 for the finasteride (n = 99) and placebo arms (n = 99), respectively (MD = 0.21). and Grossman EB for the PREDICT Study Investigators. Current clinical practice of prescribing 5 mg finasteride is validated by the evidence presented here: finasteride is clinically efficacious and has few sexual adverse effects that dissipate past 1 year followup. Of 4 trials with endpoints from 2 to 4 years, only 1 trial showed finasteride improved scores clinically, although all 4 found finasteride significantly improved scores versus placebo. Federal government websites often end in .gov or .mil. asthenia = 9.1% versus 10.5% (RR 0.87, 95% CI 0.58 to 1.30). MedCity Influencers, Legal. We did not, a priori, define 'serious AEs', although it would have been helpful if we had. Two trials compared finasteride to phytotherapies (1614 men) (Carraro 1996 = Permixon; For drugrelated adverse effects, there was no statistically significant difference for finasteride versus tamsulosin. Longterm effects of finasteride in patients with benign prostatic hyperplasia: a doubleblind, placebocontrolled, multicenter study. Lee M, *"Improved" and "worse" were defined as a change of one or more episodes. Byrnes and we also found a significant difference favoring placebo for 'decreased libido', and 'ejaculation disorder'. et al. Finasteride is used to treat enlarged prostate (benign prostatic hyperplasia) and male pattern hair loss. Our statistical analysis was performed according to the Cochrane Handbook for Systematic Reviews of Interventions (Cochrane Handbook 2008). Both are relatively inexpensive and may cost you less than $10 a month with a GoodRx coupon. et al. Wise H, Yu 1995 (N = 50) reported significant improvement in the finasteride arm versus placebo (MD 15.00, 95% CI 21.67 to 8.33). Quarterwatch 2012Q2: 79. Lepor 1996 reported absolute mean changes in the AUASI of 3.2 and 6.2 points for finasteride versus combination therapy, respectively (P < 0.001), but only combination therapy was clinically significant ( 4 point decrease). Note: Although finasteride has been studied for hair loss in women, this use is considered off-label. A multi center, randomized, doubleblind, placebocontrolled trial for men with moderate symptomatic BPH. At 4 years, both finasteride and doxazosin improved urinary symptom scores clinically; headtohead, the comparison was significant (P = 0.001) and favored doxazosin (McConnell 2003). Liss CL, For 'patients reporting adverse effects' we pooled the two trials; the comparison was not significant (RR 2.16, 95% CI 0.33 to 14.04), but inexplicably, had significant heterogeneity (I = 92%). All nine trials reported statistically significant improvements for prostate volume for finasteride versus placebo at endpoints from 6 months to 1 year. The comparison was significant (P = 0.002). Proscar is used to treat men who have benign prostatic hyperplasia (BPH) with an enlarged prostate. Presumably patients were blinded; not sure if the second blinded group were providers or assessors. Urine flows improved for both finasteride + terazosin and terazosin monotherapy but were not significantly different (P = 0.15). Agrawal 2001, the source of the heterogeneity, has a point estimate of 3.20 (95% CI 2.08 to 4.32), whereas the other 4 trials had point estimates from 10 to 2 fold of Agrawal. Tacklind J. Skeland 2000 = PRO 160/120). Even so, its important to take finasteride as prescribed. Grino P, The usual dose of 5 mg of finasteride was used in all but 3 trials. Saltzman B, The original search was repeated on 4 March, 2010; one other trial was identified, resulting in a total of 23 unique studies meeting all inclusion criteria. Lepor 1996, in a 4armed trial (other comparators were terazosin and terazosin + finasteride) utilizing the AUASI (range 0 to 35), reported absolute mean changes at 1 year of 3.2 and 2.6 points for finasteride (n = 310) and placebo (n = 305), respectively. Mobley D, The intra group comparison was significant. This review will be replaced by a new review with expanded scope on the topic of 5alpha reductase inhibitors for lower urinary tract symptoms secondary to benign prostatic obstruction. Comparing study discontinuations, the comparison was not statistically significant (Kirby 2003) (RR 1.08, 95% CI 0.83 to 1.40). Three trials (Agrawal 2001; Gormley 1992; Tammela 1993) compared 5 mg finasteride to placebo at endpoint, which was a nonsignificant difference (MD 5.64, 95% CI 18.87 to 7.59), but with considerable heterogeneity (I = 93%). Koppel M, Remember that these recommendations come directly from the manufacturers. The comparison just reached significance (RR 0.72, 95% CI 0.53 to 0.98). et al. We did not accept quasi randomized trials for inclusion. Coffey DS, The analysis had significant heterogeneity (I2 = 87%) (a ratio of nearly 3:1 between events per arm) and for which we had no explanation. You can also discuss missed dose management with your healthcare provider and pharmacist if you find that its happening regularly. All were categorized as moderately symptomatic at baseline. Finasteride and PRO 160/120 improved flows to about 2 mL/s. And its available in two different versions: Propecia and Proscar. Common side effects of Viagra include flushing, muscle pain (myalgia), nausea, back pain, problems . Gormley 1992 (N = 895) and the Finasteride Study Group compared 1 mg finasteride to placebo; the comparison was not significant (RR 0.91, 95% CI 0.56 to 1.47). The comparison was significant (P < 0.05). Daily use for 3 months or more is necessary before benefit is observed. Relative risk was not significant (RR 0.90, 95% CI 0.64 to 1.28). Followup ranged from 6 to 48 months. Lowe FC, The comparison was not significant (RD 0.01, 95% CI 0.01 to 0.03). Tammela 1993 (N = 36), which reported no numbers for adverse effects, said "[f]inasteride . Lepor found no significant difference between arms (RR 1.35, 95% CI 0.96 to 1.88). All combined outcomes were assessed by the randomeffects model. Sexual function matters greatly to many men what should they be told about this? Noble WR, GarcaPerdomo HA, Holtgrewe HL, N Engl J Med, December 18, 2003;349(25):2387-98. "Patients and investigators were unaware of treatment allocation". > 50 cc = MD 2.40 points, 95% CI 0.04 to 4.76. One reviewer (JT) assessed study characteristics and extracted data. Both trials reported the validated IPSS score. The weighted mean score was 17.8 points for IPSS/AUASI (8 trials), 14.5 points for Boyarsky I (range 0 to 54, 3 trials), and 9.8 points for Boyarsky II (range 0 to 36, 1 trial). Statistical significance was not reported. Tenover L, What is lacking is a tamsulosin trial with a placebo arm that is sufficiently powered and of at least a year's duration. From years 1 to 4 (Table 15), improvements were virtually the same, changing from 47.9% to 47.3%, for combination therapy, and 47.1% to 44.7%, for monotherapy, respectively. Finasteride (Propecia) is also used to treat male pattern hair loss (gradual thinning of the hair on the . The placebo tablets were made to be identical in appearance and taste to the finasteride tablets.". Abrams P, The comparison was not significant (MD 0.50, 95% CI 2.25 to 1.25). For men with baseline prostates of < 25 mL, 25 to < 40 mL, 40 mL, combination therapy significantly improves symptom scores for all groups, versus finasteride alone. The absolute risk of progression was 0% (Kirby 2003) (RD 0.00, 95% CI 0.01 to 0.01). government site. McConnell 2003, comparing peak urine flow at 4 years, found finasteride (n = 551) significantly better than placebo (n = 519). Finasteride Study Group. The weighted means for peak urine flow measures at baseline per comparison were: finasteride ( 5 mg) = 10.6 mL/s versus placebo = 10.5 mL/s, 15 trials; finasteride ( 1 mg) = 9.2 mL/s versus finasteride (5 mg) = 9.2 mL/s, 1 trial; finasteride ( 5 mg) = 10.8 mL/s versus Permixon = 10.6 mL/s, 1 trial; finasteride ( 5 mg) = 12.7 mL/s versus PRO 160/120 = 12.7 mL/s, 1 trial; finasteride ( 5 mg) = 10.5 mL/s versus doxazosin = 10.3 mL/s, 2 trials; finasteride + doxazosin = 10.5 mL/s versus finasteride = 10.5 mL/s, 2 trials; finasteride + doxazosin = 10.5 mL/s versus doxazosin = 10.3 mL/s, 2 trials; finasteride ( 5 mg) = 10.4 mL/s versus tamsulosin = 10.3 mL/s, 2 trials; finasteride ( 5 mg) = 10.6 mL/s versus terazosin = 10.5 mL/s, 1 trial; finasteride ( 5 mg) = 10.6 mL/s versus finasteride + terazosin = 10.4 mL/s, 1 trial; finasteride ( 5 mg) = 7.0 mL/s versus allylestrenol = 8.4 mL/s, 1 trial. Edwards (Edwards 2002) wrote "Significantly more sexual dysfunction, impotence, ejaculation disorder and decreased libido occurred with finasteride at 12 months," results which we confirmed as well. The inter group comparison was not significant. Malek GH, Now, youll enjoy a streamlined experience created specifically for healthcare providers. Marberger 1998 (N = 2902) reported significant differences between finasteride and placebo at 12, 20, and 24 months. If you have questions about your finasteride dosage, speak with your healthcare provider or pharmacist. et al. This study reports partial outcomes for the included trial McConnell 1998. Barsky AJ, Discontinuation of alphablockade after initial treatment with finasteride and doxazosin in men with lower urinary tract symptoms and clinical evidence of benign prostatic hyperplasia, Effect of finasteride on bother and healthrelated quality of life associated with benign prostatic hyperplasia, Endocrine therapy for benign prostatic hyperplasia, Finasteride in the treatment of benign prostatic hyperplasia, Fiveyear followup of patients with benign prostatic hyperplasia treated with finasteride. One trial reported prostate sizes of 61.7 for the combined finasteride 1 mg and 5 mg dose group and 108.7 cc for the placebo arm, respectively (Tempany 1993). The comparison was significant (P = 0.035). One trial reported equivalent improvements for finasteride + doxazosin versus doxazosin, while another found combination therapy significantly better. We also handsearched systematic reviews, references, and clinicalpractice guidelines. This huge and heroic review does not address some crucial questions related to adverse effects (AEs). Roehrborn (Roehrborn 1998) found a positive correlation between symptom scores and peak urine flows (i.e., improved symptom scores correlated with improved urine flows), a finding we confirmed. Johnson 2007 (McConnell 2003) reported mean changes from baseline for men defined as subjects who completed at least 1 year of the trial and had nocturia at baseline aged < 70 versus 70 years old. At both 1 and 4 years, more men reported finasteride was better than placebo (38.7% versus 35.8% and 42.6% versus 40.4%, respectively) at improving their nocturia. Byrnes and Tenover 1997, in a metaanalysis using the validated BPH Impact Index (BII) (range 0 to 35 higher numbers denoted worse symptoms) also found no difference between finasteride and placebo (MD 0.36, 95% CI 0.87 to 0.15). Kutner MH, Finasteride significantly increased the relative risk of ejaculation disorder (marginally) and impotence versus combination therapy. As a library, NLM provides access to scientific literature. Twentytwo of twentythree trials (96%) dealt adequately with incomplete outcome data. Do some AEs wane and disappear when finasteride is stopped, whereas others persist? At 4 years, combination therapy significantly improved symptom scores versus finasteride alone; improvements in both arms were clinically significant as well ( 4 point decrease in the AUASI/IPSS). Paick SH, Changes ("improved" and "worse" were defined as a change of one or more episodes) from baseline were substantial, from 38.7% and 47.1% for finasteride and doxazosin, respectively, at 1 year. LUTS secondary to BPH are believed to be caused by bladder irritation or obstruction, which in turn are caused by prostatic enlargement or small muscle contractions within the bladder or prostate. No. Ewing LL. Our search strategy found 23 trials meeting inclusion criteria. postural hypotension (4.33/3832 versus 2.56/3600). We handsearched relevant peerreviewed journals. In the Sexual Function Score (range 0 to 20), finasteride experienced a significant deterioration (9% increase) versus Permixon (6% decrease). Seventeen trials reported baseline prostate volumes for an accumulative weighted mean of 43.7 cc for the finasteride arm (5 mg), and 46.1 cc for the placebo arm. The other, an unambiguously singleblinded trial, Lee 2002 (finasteride versus tamsulosin), did not report who was blinded, although presumably it was the subjects. For androgenetic alopecia (male hair loss) the dose is 1 mg once a day. Flomax and Viagra are both drugs prescribed to men who are having difficulty urinating due to and enlarged prostate gland (benign prostatic hyperplasia, BPH). At 1 year followup, combination therapy and doxazosin alone improved scores clinically; the intercurrent comparison was not significant. Bannow J, Lepor 1998 (Lepor 1996) also reported improvements in peak urine flows, for finasteride versus combination therapy, by the same cut points: All comparisons favored combination therapy but only the first two were significant. Under Secondary outcomes in the sentence "Secondary outcomes included peak urine flow, measured in mL/s (millilitres per second), prostate size, measured in cc (cubic centimetres), BPH progression (defined as a 4 point increase from baseline to endpoint of the IPSS/AUASI; acute urinary retention; or need for surgical intervention), postvoid residual volume (cc), nocturia, adverse events and effects (or both), and quality of life (QoL). II TM, Boyle P, If you miss a dose of this medicine, skip the missed dose and go back to your regular dosing schedule. As can be seen from Table 13 below, finasteride increased the absolute risk of progression ( 4 points) by 1.19%, 1.18%, and 1.90%, respectively. Also needed is a high quality, comparative effectiveness trial with dutasteride. Gl O, Intracurrent comparisons for finasteride and PRO 160/120 were not significant (MD 0.70, 95% CI 0.55 to 1.95, and MD 0.70, 95% CI 0.82 to 2.22, respectively). Versus placebo, men taking finasteride significantly had smaller prostate volumes versus placebo for both younger (< 65 years old) and older ( 65 years) men. At 4year endpoint for selfreported nocturia, and without statistical significances, doxazosin lowered risk versus finasteride. A report about an ongoing trial of the drug from Raleigh-based Sprout Pharmaceuticals for treatment of low sexual desire in women finds in interim results that the so called 'female Viagra' can . Finasteride + doxazosin were significantly better than doxazosin at improving urine flows. Stating that, it may be impossible to answer definitively. We did not consider as eligible studies comprising men presenting with or treated for hematuria. Dosage. > 50 cc = 2.7 versus 3.7 mL/s, respectively (MD 1.00 mL/s, 95% CI 2.69 to 0.69). Finasteride consistently improved urinary symptom scores more than placebo in trials of > 1 year duration, and significantly lowered the risk of BPH progression (acute urinary retention, risk of surgical intervention, 4 point increase in the AUASI/IPSS). Johnson did not report if the comparison was significant or not. No statistical significances were given. Stoner E. Maximum urinary flow rate by uroflowmetry: automatic or visual interpretation. Men with symptomatic BPH as determined by urinary symptoms or symptomscale scores. Dorey FJ, Koch G, 'ejaculation disorder' = 2.4% versus 0.4% (RR 6.73, 95% CI 0.83 to 54.35), 'impotence' = 10.5% versus 5.8% (RR 1.80, 95% CI 1.01 to 3.23), and. Vaughan D, Johnson 2007, in a post hoc analysis of the included trial by McConnell 2003 (hereafter referenced as Johnson 2007 (McConnell 2003)), reported baseline incidences in men with "1 or more" episodes at baseline. Tveter K, Drugrelated adverse effects were rare; none were greater than 5 per 100 personyears of followup. There were mean changes of 0.40% and 0.54% nightly incidents for finasteride (n = 653) and doxazosin (n = 649), respectively. Combination therapy also reduced the absolute risk of progression ( 4 point increase) by 4%, but the absolute risk of surgery was 0%. For endpoints > 1 year, finasteride did not significantly reduce nocturia versus placebo. Polat 1997 (N = 123), with a 1 year followup, noted improvements in prostate size for both arms to endpoint, with significant differences favoring finasteride at 3, 6, and 9 and 12 months. At 1 year, terazosin significantly improved symptom scores versus finasteride, and was clinically significant as well ( 4 point decrease in the AUASI/IPSS). Napumpujte ho antioxidantmi a vitamnmi! For terazosin, there was an (non significant) absolute risk reduction of 1% (Lepor 1996) (RD 0.01, 95% CI 0.01 to 0.03). Partin AW, Bruskewitz RC, 40 cc = MD 2.60 points, 95% CI 1.49 to 3.71; > 40 cc 50 cc = MD 4.40 points, 95% CI 1.91 to 6.89; and. Continued use is recommended to sustain benefit. Finasteride also decreased, at endpoints > 1 year, the absolute risk of progression ( 4 point increase), as well as acute urinary retention, and the absolute risk of surgery. Saltzman B, et al. et al. Crushed or broken tablets should not be handled by women who are or may potentially be pregnant. For benign prostatic hyperplasia: Adults5 milligrams (mg) once a day. Statistical evidence of heterogeneity was assessed graphically and by the I statistic. Pommerville PJ, > 50 cc = 2.7 versus 0.6 mL/s (MD 2.10 mL/s, 95% CI 0.85 to 3.35). The tour begins on Aug. 3 in Sterling . For men with large prostates (> 40 cc), finasteride significantly, if modestly, improved symptom scores versus men taking finasteride and with small ( 40 cc) prostates. Finasteride 1mg daily is FDA-approved for male pattern baldness, while the 5mg dose is approved for management of prostatic hypertrophy. "men at each site were randomly assigned by a central computer in equal proportions", "statistical analyses were based on the intentiontotreat principle; that is, the results for all men for whom any followup data were available were included in the analyses of the treatment groups to which the men had been assigned". In general, taking too much of a medication can increase the risk of side effects. Of men with 2 or more episodes at baseline, 25% (52/205) and 32% (63/195) in the finasteride and combination arms, respectively, experienced 50% or greater reductions. Response: James Tacklind, Howard A Fink, Roderick MacDonald, Indy Rutks, Timothy J Wilt, Protocol first published: Issue 2, 2006 A clinically meaningful change is defined as a variance of 4 points from baseline (Barry 1995). Kontturi M, Twentyone trials were free of selective reporting. Most reported outcomes were for 26 weeks. ImperatoMcGinley J, Jr GL, participants were "doublemasked" to intervention; providers and assessors were not blinded, losses to followup for placebo were not reported. Finasteride is a prescription medication that belongs to a class called 5-alpha reductase inhibitors. A post hoc analysis of the included trial, McConnell 2003. Clinical trials have shown mixed results for the benefit of saw palmetto when treating benign prostatic hyperplasia. . et al. Weighted, baseline mean IPSS/AUASI differed slightly by comparisons: finasteride (5 mg) = 18.2 points versus placebo = 17.0 points, 7 trials; finasteride (5 mg) = 15.7 points versus Permixon = 15.7 points, 1 trial; finasteride (5 mg) = 11.8 points versus PRO 160/120 = 11.3 points, 1 trial; finasteride (5 mg) = 17.5 points versus doxazosin = 17.0 points, 2 trials; finasteride (5 mg) + doxazosin = 16.9 points versus finasteride = 17.5 points, 2 trials; finasteride (5 mg) + doxazosin = 16.9 points versus doxazosin = 17.0 points, 2 trials; finasteride (5 mg) = 17.6 points versus tamsulosin = 19.9 points, 2 trials; finasteride (5 mg) = 16.2 points versus terazosin = 16.2 points, 1 trial; finasteride (5 mg) = 16.2 points versus finasteride + terazosin = 15.9 points, 1 trial. A total of 21,945 men were randomized (finasteride = 11,086; tamsulosin = 302; terazosin = 340; doxazosin = 1031; Permixon = 553; PRO 160/120 = 261; finasteride + doxazosin = 1072; finasteride + terazosin = 309; placebo = 6956; allylestrenol = 35). Marberger MJ, Anderson R, For example, were participants asked specific or open questions at particular time points, and what questions? If still bothered, pharmacologic interventions such as fivealpha reductase inhibitors, including dutasteride and finasteride, and alpha1adrenoreceptor antagonists (alpha blockers) are often recommended. The MTOPS trial (McConnell 2003), to see if change in PSA, as a surrogate endpoint, was affected by active interventions, compared finasteride to doxazosin. The comparison was not significant. Letonen T, Schafer W, The comparison was not significant (MD 0.44, 95% CI 2.57 to 1.69). Stoner E, The endpoint comparison was not significant (MD 3.30, 95% CI 4.93 to 11.53). However, the endpoint comparison was not significant (MD 2.30 mL, 95% CI 5.64 to 10.24). The only missing comparator was dutasteride, another commonly used 5ARI. 1 It's the same medication as for sexual and erectile dysfunction, but it's just taken daily as a lower dose. Byrnes CA, Andersen JT, (2022). Drugrelated adverse effects are rare, although finasteride has higher rates of erectile dysfunction, decreased libido, and abnormal ejaculation, whilst doxazosin had higher rates of dizziness, postural hypotension, and asthenia. Mean Difference (IV, Random, 95% CI). Both monotherapy and combination therapy improve scores clinically as well. Combination therapy (finasteride + doxazosin) significantly improves symptom scores versus finasteride alone. In a metaanalysis of endpoints of 5 trials, finasteride was significantly better than placebo (MD 1.36, 95% CI 0.26 to 2.47), but with considerable heterogeneity (I2 = 77%) (Analysis 1.16). Johnson did not report if either comparison was significant. The inter group comparison was significant as well (P < 0.001).
