Association of silodosin, tamsulosin, and naftopidil with delirium: analysis of the pharmacovigilance database in Japan. Int J Clin Pharm 2023; 45:1252-1259. [PMID: 37713027 DOI: 10.1007/s11096-023-01639-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 08/17/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUND An association between adrenergic alpha-1 receptor antagonists and delirium has been suggested, but the details are unclear. AIM This study investigated the association between adrenergic alpha-1 receptor antagonists and delirium in patients with benign prostatic hyperplasia using the Japanese Adverse Drug Event Report database. METHOD First, disproportionality analysis compared the frequency of delirium in the adrenergic alpha-1 receptor antagonists silodosin, tamsulosin, and naftopidil. Next, multivariate logistic analysis was performed to examine the association between delirium and adrenergic alpha-1 receptor antagonists where disproportionality was detected. RESULTS A disproportionality in delirium was observed in patients receiving tamsulosin (reporting odds ratio [ROR] 1.85, 95% confidence interval [CI] 1.38-2.44, P < 0.01) compared with those who did not, and also in patients receiving naftopidil (ROR 2.23, 95% CI 1.45-3.28, P < 0.01) compared with those who did not. Multivariate logistic analysis revealed that in addition to previously reported risk factors for delirium, delirium in patients receiving tamsulosin was significantly increased with concomitant use of anticholinergics (odds ratio 2.73, 95% CI 1.41-5.29, P < 0.01) and delirium in patients receiving naftopidil was significantly increased with concomitant use of beta3-adrenergic receptor agonists (odds ratio 4.19, 95% CI 1.66-10.6, P < 0.01). CONCLUSION Anticholinergics or beta3-adrenergic receptor agonists to treat overactive bladder in patients receiving tamsulosin and naftopidil was strongly associated with delirium. Confirming the medical history and concomitant medications of patients receiving tamsulosin or naftopidil may contribute to preventing delirium in patients with benign prostatic hyperplasia and to improving their outcomes.

Abstract
Tamsulosin and dutasteride are drugs widely used to treat benign prostatic hypertrophy. having a good safety profile. There are few reports of liver injury associated with the use of tamsulosin; however, there are no reports of hepatic toxicity from the use of dutasteride and the combined use of tamsulosin/dutasteride. We present the case of a 64-year-old man who developed liver injury after the combined use of tamsulosin/dutasteride, developing a pattern of hepatocellular damage and acute hepatitis symptoms. Viral, autoimmune, and metabolic storage diseases of the liver were ruled out, as well as biliary pathology by means of abdominal ultrasound and resonance cholangiography. In the causality evaluation, CIOMS-RUCAM presented: 6 points (probable) and Naranjo: 4 points (possible). The patient presented a clinical and laboratory response after discontinuing the drug.

Abstract
OBJECTIVE To describe two cases of man with the diagnosis of ischemic priapism after the intake of tamsulosin and to revise the scientific literature. METHODS We present two cases of men that developed an ischemic priapism after the intake of tamsulosin prescribed for STUI and were treated in our hospital. We described the two cases, from the diagnosis until the surgery that was performed. Also, we review the scientific literature about this topic. RESULTS In one hand, a 67 years old man with the previous diagnosis of diabetes mellitus, hypertension and dyslipidemia that take a one single dosis of tamsulosin and developed a priapism of 9 hours of duration. He was diagnosticated of low-flow priapism that was reverted after the use of intracavernosal phenylephrine. On the other hand, a 61 years old man without any medical condition. He developed a priapism after the intake of also one single dosis of tamsulosin and came to the hospital after 48 hours of the beginning of the erection. In this case, the use of intracavernosal phenylephrine wasn´t effective so we decided to performed a distal shunt between cavernosal and spongy body according to the techniques of Winter, Ebbehoj and Al-Ghorab. All of them without results. At the end, we tried a proximal shunt according Quackles technique, also ineffective. The patient declined another surgery for implantation of a pennis prothesis and went home after four days of hospitalization with the disappearance of the pain. CONCLUSIONS The tamsulosin is a drug well known by urologist that have a safety profile probed with the years. Nevertheless, it's association with a disease like the priapism forced us to explain to our patients this rare adverse effect.

Tamsulosin and risk of priapism: A causality assessment using Austin Bradford Hill Criteria. Pharmacol Res Perspect 2022; 10:e00934. [PMID: 35170870 PMCID: PMC8848631 DOI: 10.1002/prp2.934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 01/22/2022] [Indexed: 11/16/2022] Open
Abstract
Tamsulosin hydrochloride, a selective alpha-adrenergic blocking agent has been previously associated with priapism. Priapism is a medically serious condition that, if not intervened, can cause permanent erectile dysfunction. This study was conducted to investigate whether the association of tamsulosin and priapism is causal. All currently available evidence such as experimental, biological, toxicological, published studies, and safety data mined from the WHO global pharmacovigilance database was systematically organized into the Austin Bradford Hill causality assessment framework. In the international pharmacovigilance database, a strong association between tamsulosin and priapism (IC025 = 4.1; PRR025 = 19.9; ROR025 = 20) was observed. There were 122 cases of priapism associated with tamsulosin submitted to the database from 23 countries. In 87.7% of the cases, tamsulosin was reported as a 'sole suspect,' and in 50.8%, it was the only drug administered. In several patients, priapism resolved following discontinuation of tamsulosin and recurred after its reintroduction. Both in the published and unpublished data, for majority of the cases, the time to onset of priapism was within few days following the first intake of tamsulosin. Cases of priapism, particularly those published, were consistent in their clinical features with patients experiencing prolonged painful erection that required aspiration of cavernosal blood, irrigation of the corpora cavernosa, and treatment with vasopressors. Other alpha-adrenergic blocking agents that are structurally analogous with tamsulosin have also been associated with priapism. In several cases, tamsulosin was used off-label, for the treatment of ureteral calculi expulsion. Eight patients experienced priapism that ended up with serious complications such as ejaculation disorders and erectile dysfunction. The currently available totality of evidence suggests that the association of tamsulosin and priapism is causal. Healthcare professionals are therefore recommended to cautiously prescribe tamsulosin and ensure that consumers are aware of the potential risk of priapism.

Efficacy and tolerability of doxazosin gastro-intestinal therapeutic system versus tamsulosin in patients with lower urinary tract symptoms associated with benign prostatic hyperplasia: A systematic review and meta-analysis. Medicine (Baltimore) 2021; 100:e26955. [PMID: 34414962 PMCID: PMC8376339 DOI: 10.1097/md.0000000000026955] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 07/30/2021] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Alpha1-adrenoceptor antagonists (α1-blockers) are first-line drugs for the treatment of lower urinary tract symptoms associated with benign prostate hyperplasia (BPH). Doxazosin gastrointestinal therapeutic system (GITS) and tamsulosin belong to the 2 most frequently prescribed α1-blockers. This systematic review and meta-analysis was performed to compare the efficacy and tolerability of these 2 α1-blockers. METHODS A systematic review of published randomized controlled trials in English or Chinese language was performed using the PubMed, EMBASE, Cochrane Library, CNKI, Wanfang, and Vip databases. After data extraction and quality assessment, the meta-analysis was performed to compare clinical parameters (International Prostate Symptom Score [IPSS] total [IPSS-T], storage [IPSS-S], voiding [IPSS-V], maximum urine flow [Qmax], and postvoid residual) and adverse events (AEs) that changed after first drug intake. RESULTS After the screening, 8 eligible randomized controlled trials with 1316 patients were identified. Doxazosin-GITS showed a significantly higher efficacy compared with tamsulosin (IPSS-T P < .001, IPSS-S P < .001, and IPSS-V P < .001). There were no significant differences between the 2 drugs for changes in Qmax (P = .477) or postvoid residual (P = .739). The overall AEs were significantly lower in the doxazosin-GITS group (risk ratio: 0.77; 95% CI: 0.54-1.08; P = .036). However, dizziness (P = .387), headache (P = .745), asthenia (P = .693), postural hypotension (P = .114), and retrograde ejaculation (P = .187) were similar between the 2 groups. CONCLUSIONS This meta-analysis indicates that doxazosin-GITS has significantly higher efficacy and lower AEs than tamsulosin in patients with lower urinary tract symptoms/benign prostate hyperplasia.

Preoperative Tamsulosin to Prevent Postoperative Urinary Retention: A Randomized Controlled Trial. J Surg Res 2021; 262:130-139. [PMID: 33561724 DOI: 10.1016/j.jss.2020.12.055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 11/17/2020] [Accepted: 12/16/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy of tamsulosin, administered preoperatively, for the prevention of postoperative urinary retention (POUR). POUR is a common complication of abdominal surgery, leading to the use of urinary catheters, which are a risk factor for urinary tract infection. Tamsulosin is a uroselective alpha-1a blocker used for the treatment of lower urinary tract symptoms. MATERIALS AND METHODS A randomized, double-blind, placebo-controlled trial was undertaken from August 2015 to May 2018. Adults undergoing elective inpatient abdominal surgery were randomized to receive either tamsulosin 0.4 mg or placebo daily for 7 d before surgery and continuing for up to 7 d postoperatively. The primary outcome was need for at least a single intermittent catheterization postoperatively. Secondary outcomes included first postvoid residual volume, number of catheterizations, need for replacement of an indwelling catheter, hospital length of stay, and urinary tract infection within 30 d of surgery. RESULTS A total of 158 participants were enrolled, with a final analytic cohort of 141 participants. The two groups had similar baseline characteristics, operative characteristics, and timing of catheter removal. There was no difference in the incidence of POUR between the two groups (26% in tamsulosin versus 31% in placebo, P = 0.49). There was also no difference in any of the secondary outcomes between the two groups. Epidural usage, open surgery, and age <50 were identified as risk factors for POUR. CONCLUSIONS Perioperative prophylaxis with tamsulosin is not effective in reducing the incidence of POUR in patients undergoing elective abdominal surgery.

Abstract
Studies suggest that the use of alpha-blockers increases the risk of dementia in patients with benign prostate hyperplasia (BPH). Due to study limitations, the relationship between the use of alpha-blockers, such as tamsulosin, and the risk of dementia is still unclear. However, alpha1-adrenoreceptors are also present in the brain, so there is potential for adverse effects on cognitive function. Therefore, we investigated possible associations between the use of alpha-blockers and aggravation of cognitive decline in dementia patients using a clinical data analytic solution called the Smart Clinical Data Warehouse (CDW).We retrospectively investigated clinical data using the Smart CDW of Hallym University Medical Center from 2009 to 2019. We enrolled patients with probable Alzheimer disease (AD) who had completed the Mini-Mental State Examination (MMSE) at least twice during follow-up, and who had BPH. We compared the difference in MMSE scores between patients who took tamsulosin for >1000 days and those who did not take any alpha-blocker. We tested the effect of tamsulosin on cognitive decline in patients with AD, using propensity score-matched logistic regression analysis.Eligible cases were included in the tamsulosin (n = 68) or no-medication (n = 153) groups. After propensity score matching, clinical characteristics such as educational attainment and vascular risk factors were similar in the tamsulosin and no-medication groups. The MMSE scores did not differ significantly between the tamsulosin and no-medication groups (P = .470).The results suggest that tamsulosin for BPH is not associated with worsening of the cognitive decline in patients with AD.

Men's Sexual Health Questionnaire score changes vs spontaneous sexual adverse event reporting in men treated with dutasteride/tamsulosin combination therapy for lower urinary tract symptoms secondary to benign prostatic hyperplasia: A post hoc analysis of a prospective, randomised, placebo-controlled study. Int J Clin Pract 2020; 74:e13480. [PMID: 31927774 PMCID: PMC7187250 DOI: 10.1111/ijcp.13480] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 01/08/2020] [Indexed: 11/30/2022] Open
Abstract
AIM To assess the impact of baseline characteristics on Men's Sexual Health Questionnaire (MSHQ) total scores and to evaluate the clinical relevance of MSHQ changes and their association with spontaneously reported sexual adverse events (SexAEs) in patients with benign prostatic hyperplasia. METHODS This was a post hoc analysis of the Phase 4 FDC116115 study, in which patients aged ≥50 years were randomised 1:1 to receive a fixed-dose combination of dutasteride 0.5 mg and tamsulosin 0.4 mg (DUT-TAM FDC), or placebo. End-points included: change in MSHQ total scores by baseline characteristics and SexAEs; cumulative distribution function for change from baseline to month 12 in MSHQ total score and the ejaculation, erection, satisfaction and sexual desire (libido) domain scores; and relationship between changes in MSHQ scores and SexAEs. RESULTS The intent-to-treat population comprised 489 patients (DUT-TAM FDC, n = 243; placebo, n = 246). The mean reduction in total MSHQ score was greater in patients with SexAEs across both groups, compared with patients without SexAEs. Most patients reporting any SexAE (86% DUT-TAM FDC, 67% placebo) had a worsening of the MSHQ total score at month 12 compared with baseline. Specifically, 90% (DUT-TAM FDC) and 75% (placebo) of patients reporting an ejaculation SexAE and 73% (DUT-TAM FDC) and 87% (placebo) of patients reporting an erection SexAE had a worsening of MSHQ ejaculation and erection domain scores, respectively, at month 12. A threshold effect for incident SexAE was observed; patients showing a decrease of approximately 6-10 points in the total MSHQ score were more likely to report SexAEs. CONCLUSION Findings support the clinical utility of the MSHQ tool in assessing the impact of DUT-TAM on sexual function by linking numerical changes in MSHQ scores to spontaneously reported SexAEs for the first time. The threshold effect for incidence of SexAEs warrants further investigation to determine its clinical relevance.

Abstract
BACKGROUND Drug therapy for lower urinary tract symptoms (LUTS) secondary to benign prostate hyperplasia (BPH) is a major and popular method. However, the therapeutic strategy is still not clear enough up to now. The purpose of this study was to compare the relative safety and efficacy of different types of phosphodiesterase type 5 inhibitors (PDE5-Is) with tamsulosin for the treatment of LUTS secondary to BPH. METHODS Databases including PubMed, OpenGrey, Embase, Cochrane Library, and Web of Science will be searched to identify qualified studies. We will use the Stata version 13.0 to conduct the network meta-analysis (NMA) with a random or fixed effects model of Bayesian framework. International prostate symptom score (IPSS), maximum urinary flow fate (Qmax) and their credible intervals (CI) will be used to compare every medical intervention with the efficacy and safety, including sildenafil plus tamsulosin, tadalafil plus tamsulosin, vardenafil plus tamsulosin. And the ranking of probability of different interventions will be estimated by comparing the surface under the cumulative ranking curve (SUCRA). RESULTS A high quality-synthesis of the current evidence for comparing with different doses or types of PDE5-Is combined with tamsulosin to the treatment of LUTS secondary to BPH will be provided. CONCLUSIONS This NMA and systematic review will generate evidence to help choose the best combination for treatment of LUTS secondary to BPH.PROSPERO registration number: PROSPERO CRD 42019139062.

Abstract
OBJECTIVE To investigate the incidence of new onset type 2 diabetes mellitus in men receiving steroid 5α-reductase inhibitors (dutasteride or finasteride) for long term treatment of benign prostatic hyperplasia. DESIGN Population based cohort study. SETTING UK Clinical Practice Research Datalink (CPRD; 2003-14) and Taiwanese National Health Insurance Research Database (NHIRD; 2002-12). PARTICIPANTS Men in the CPRD who received dutasteride (n=8231), finasteride (n=30 774), or tamsulosin (n=16 270) were evaluated. Propensity score matching (2:1; dutasteride to finasteride or tamsulosin) produced cohorts of 2090, 3445, and 4018, respectively. In the NHIRD, initial numbers were 1251 (dutasteride), 4194 (finasteride), and 86 263 (tamsulosin), reducing to 1251, 2445, and 2502, respectively, after propensity score matching. MAIN OUTCOMES MEASURE Incident type 2 diabetes using a Cox proportional hazard model. RESULTS In the CPRD, 2081 new onset type 2 diabetes events (368 dutasteride, 1207 finasteride, and 506 tamsulosin) were recorded during a mean follow-up time of 5.2 years (SD 3.1 years). The event rate per 10 000 person years was 76.2 (95% confidence interval 68.4 to 84.0) for dutasteride, 76.6 (72.3 to 80.9) for finasteride, and 60.3 (55.1 to 65.5) for tamsulosin. There was a modest increased risk of type 2 diabetes for dutasteride (adjusted hazard ratio 1.32, 95% confidence interval 1.08 to 1.61) and finasteride (1.26, 1.10 to 1.45) compared with tamsulosin. Results for the NHIRD were consistent with the findings for the CPRD (adjusted hazard ratio 1.34, 95% confidence interval 1.17 to 1.54 for dutasteride, and 1.49, 1.38 to 1.61 for finasteride compared with tamsulosin). Propensity score matched analyses showed similar results. CONCLUSIONS The risk of developing new onset type 2 diabetes appears to be higher in men with benign prostatic hyperplasia exposed to 5α-reductase inhibitors than in men receiving tamsulosin, but did not differ between men receiving dutasteride and those receiving finasteride. Additional monitoring might be required for men starting these drugs, particularly in those with other risk factors for type 2 diabetes.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (BPH) are common in men, considerably affecting quality of life. AIMS The self-directed use of over-the-counter (OTC) tamsulosin (0.4 mg) and potential safety risks were evaluated in an open-label, uncontrolled, exploratory, 8-week OTC-simulated study. METHODS Men (≥ 18 years) were recruited via mass advertising about bothersome LUTS. In a working retail environment, respondents reviewed the product and decided whether it was appropriate for them to use (self-selection phase). After purchasing the product, participants' ability to use it as directed by the proposed drug facts label (DFL) was assessed (home-use phase). RESULTS Of 1446 eligible men, 679 completed the self-selection phase, and 73.9% (502/679) self-selected to use tamsulosin correctly according to the DFL. Of 369 participants who purchased tamsulosin and entered the home-use phase, 321 took one or more doses of tamsulosin and participated in at least one telephone interview. In total, 85.4% (274/321) of participants adhered to the 'Stop Use' and 'Directions' instructions in the DFL. Overall, 139 (39.6%) participants experienced one or more adverse events (AEs); 65 (18.5%) were deemed drug-related, including dizziness (11 [3.1%]), ejaculation disorder (6 [1.7%]), and semen volume decrease (6 [1.7%]). No unexpected AEs were reported. CONCLUSIONS Of the men interested in self-managing their LUTS, a majority had moderate-to-severe LUTS of long duration. Most men were able to appropriately self-select and use tamsulosin in concordance with DFL instructions and directions. No unexpected AEs were reported during self-directed use. With further label refinement, an over-the-counter tamsulosin option might be feasible. TRIAL REGISTRATION ClinicalTrials.gov NCT01726270.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is a common condition in ageing men that may cause lower urinary tract symptoms (LUTS). Treatment aims are to relieve symptoms and prevent disease-related complications. Naftopidil is an alpha-blocker (AB) that has a high affinity for the A1d receptor that may have advantages in treating LUTS in this setting. This is an update of a Cochrane Review first published in 2009. Since that time, several large randomised controlled trials (RCTs) have been reported, making this update relevant. OBJECTIVES To evaluate the effects of naftopidil for the treatment of LUTS associated with BPH. SEARCH METHODS We performed a comprehensive search using multiple databases (the Cochrane Library, MEDLINE, Embase, Scopus, LILAC, and Web of Science), trials registries, other sources of grey literature, and conference proceedings with no restrictions on the language of publication or publication status up to 31 May 2018 SELECTION CRITERIA: We included all parallel RCTs. We also included cross-over design trials. DATA COLLECTION AND ANALYSIS Two review authors independently classified and abstracted data from the included studies. We performed statistical analyses using a random-effects model and interpreted them according to the Cochrane Handbook for Systematic Reviews of Interventions. Primary outcomes were urological symptom scores, quality of life (QoL) and treatment withdrawals for any reason; secondary outcomes were treatment withdrawals due to adverse events, acute urinary retention, surgical intervention for BPH, and cardiovascular and sexual adverse events. We considered outcomes measured up to 12 months after randomisation as short term, and later than 12 months as long term. We rated the certainty of the evidence according to the GRADE approach. MAIN RESULTS We included 22 RCTs with 2223 randomised participants across four comparisons for short-term follow-up. This abstract focuses on only two of four comparisons for which we found data since two comparators (i.e. propiverine and Eviprostat (phytotherapy)) are rarely used. One study comparing naftopidil to placebo did not report any relevant outcomes and was therefore excluded. There were no trials that compared to combination therapy with naftopidil or any 5-alpha reductase inhibitors (5-ARIs) to combination therapy with other ABs and any 5-ARIs.All included studies were conducted in Asian countries. Study duration ranged from four to 12 weeks. Mean age was 67.8 years, prostate volume was 35.4 mL, and International Prostate Symptom Score was 18.3. We were unable to perform any of the preplanned subgroup analyses based on age and baseline symptom score.Naftopidil versus tamsulosinBased on 12 studies with 965 randomised participants, naftopidil may have resulted in little or no difference in urological symptom score (mean difference (MD) 0.47, 95% confidence interval (CI) -0.09 to 1.04 measured on a scale from 0 to 35 with higher score representing increased symptoms), QoL (MD 0.11, 95% CI -0.09 to 0.30; measured on a scale from 0 to 6 with higher scores representing worse QoL), and treatment withdrawals for any reason (risk ratio (RR) 0.92, 95% CI 0.64 to 1.34; corresponding to 7 fewer per 1000 participants, 95% CI 32 fewer to 31 more). Naftopidil may have resulted in little to no difference in sexual adverse events (RR 0.54, 95% CI 0.24 to 1.22); this would result in 26 fewer sexual adverse events per 1000 participants (95% CI 43 fewer to 13 more). We rated the certainty of evidence as moderate for urological symptom score and low for the other outcomes.Naftopidil versus silodosinBased on five studies with 652 randomised participants, naftopidil may have resulted in little or no difference in the urological symptom scores (MD 1.04, 95% CI -0.78 to 2.85), QoL (MD 0.21, 95% CI -0.23 to 0.66), and treatment withdrawals for any reason (RR 0.80, 95% CI 0.52 to 1.23; corresponding to 26 fewer per 1000 participants, 95% CI 62 fewer to 32 more). We rated the certainty of evidence as low for all these outcomes. Naftopidil likely reduced sexual adverse events (RR 0.15, 95% CI 0.06 to 0.42; corresponding to 126 fewer sexual adverse events per 1000 participants, 95% CI 139 fewer to 86 fewer). We rated the certainty of evidence as moderate for sexual adverse events. AUTHORS' CONCLUSIONS Naftopidil appears to have similar effects in the urological symptom scores and QoL compared to tamsulosin and silodosin. Naftopidil has similar sexual adverse events compared to tamsulosin but has fewer compared to silodosin.

Abstract
OBJECTIVE To verify the efficacy and safety of tamsulosin 0.4 mg and tamsulosin 0.2 mg compared with those of placebo in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). METHODS A total of 494 patients from multiple centers participated in this double-blind, randomized, phase 3 trial. Eligible patients were randomly assigned to the tamsulosin 0.4 mg group, tamsulosin 0.2 mg group or placebo group. The International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual (PVR) urine volume, blood pressure, heart rate and adverse events were compared among the three groups at 4, 8 and 12 weeks. RESULTS A total of 494 BPH patients were analyzed. There were no differences in the baseline characteristics among the three groups. After 12 weeks of treatment, total IPSS was improved in the 0.2 mg and 0.4 mg tamsulosin groups; however, the extent of improvement was greater in the 0.4 mg group than in the 0.2 mg group (0.4 mg: -9.59 vs. 0.2 mg: -5.61; least-squares mean difference [95% confidence interval]: -3.95 [-5.01, -2.89], p < .0001). In addition, in the patients with severe symptoms (IPSS ≥20), total IPSS was improved the most in the 0.4 mg group (-11.27 ± 5.00, p < .0001). Qmax and PVR were improved in the 0.4 mg and 0.2 mg groups; however, the differences were not statistically significant between treatment groups. No patients experienced any serious adverse effects in any of the three groups. CONCLUSIONS Tamsulosin 0.4 mg and 0.2 mg appear to be superior to placebo treatment, and tamsulosin 0.4 mg is more effective than 0.2 mg in terms of total IPSS improvement. Tamsulosin 0.4 mg has favorable efficacy and tolerability in Asian men with symptomatic BPH. ClinicalTrials.gov Identifier: NCT02390882.

Medical Expulsive Therapy for Symptomatic Distal Ureter Stones: Is the Combination of Bromelain and Tamsulosin More Effective than Tamsulosin Alone? Preliminary Results of a Single-Center Study. Urol Int 2018; 102:145-152. [PMID: 30227429 DOI: 10.1159/000493158] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 08/21/2018] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To assess the safety and efficacy of bromelain plus tamsulosin versus tamsulosin alone as medical expulsive therapy (MET) for promoting spontaneous stone passage (SSP) of symptomatic distal ureter stones. PATIENTS AND METHODS One-hundred-fourteen patients with a 4-10 mm distal ureteral stone were enrolled (Group A). Patients self-administered daily bromelain with tamsulosin for 30 days or until SSP or intervention was mandatory. Patients were compared to those from a control group taking tamsulosin as MET (Group B) and matched for the following factors: sex, age ±10%, stone diameter. A logistic regression model evaluated bromelain and the ureteral stone diameter as explanatory variables. RESULTS SSP rates were 87.7 vs. 75.4% for group A vs. group B respectively (p = 0.016); with no difference observed for the time to self-reported stone expulsion (11.68 vs. 11.57 days; p = 0.91). Considering larger stones (> 5 mm), the SSP rate was 83.3% in group A and 61% in group B (p < 0.01). With each millimeter increment of stone diameter, the probability of SSP decreased by 59.1% (p < 0.0001), while it increased of 3.3 when bromelain was present. Only 3 cases of tamsulosin-related adverse events were recorded. CONCLUSION The association of bromelain and tamsulosin as MET increases the probability of SSP of symptomatic distal ureteral stones, with no bromelain-related side effects recorded.

Abstract
OBJECTIVE To compare the efficacy and safety of silodosin against tamsulosin as medical expulsion therapeutic agent in stone lower 1/3rd ureter. PATIENTS AND METHODS One hundred fifty patients divided equally into 2 groups I and II received silodosin 8 mg and tamsulosin 0.4 mg respectively. Patients aged 18 years or older having single unilateral stone 10 mm or less were included in the study. Patients with bilateral or multiple stones, marked hydronephrosis, previous open or endoscopic surgery and having urinary infection were excluded. Patients were followed weekly for 4 weeks by ultrasonography, plain radiography of the urinary tract and CT of the urinary tract when indicated. RESULTS Silodosin showed better results against tamsulosin as stone expulsion rate in silodosin and tamsulosin groups was 82.4 and 61.5% respectively with significant difference (p = 0.007). Also, the stone expulsion time was significantly lower in silodosin against tamsulosin groups as it was 9.4 ± 3.8 vs. 12.7 ± 5.1 days in group I and II respectively (p = 0.001). The adverse effects were comparable with non-significant more retrograde ejaculation in the silodosin group. CONCLUSION Silodosin showed better efficacy in the stone expulsion rate and time with comparable safety of both drugs, with nonsignificant more retrograde ejaculation in silodosin.

Abstract
OBJECTIVE To investigate the therapeutic effects of commonly used selective α-adrenergic receptor antagonists (α-ARA) on benign prostatic hyperplasia (BPH). METHODS PubMed, Embase and CNKI databases were searched for the literature about selective α-ARAs for the treatment of BPH and the information was extracted on the common adverse reactions in the course of treatment. Multivariate meta-analysis was conducted to investigate the therapeutic effects of different α-ARAs. RESULTS The total rates of adverse effects of silodosin and tamsulosin were the highest, 51.9% and 34.0% respectively, with the highest incidences of headache (38.3%), weakness (23.6%) and dizziness (17.5%). Besides, tamsulosin ranked the first in inducing sexual dysfunction of the male patients with BPH (70.4%). CONCLUSIONS Doxazosin is preferable as the first-choice treatment of BPH for its therapeutic effect and improvement of the patient's quality of life. Silodosin and tamsulosin, however, can be selectively used according to the patient's specific tolerance to different adverse effects.
