Overview

Basic Info

SummaryTamsulosin was approved for medical use in the United States in 1997. Specifically it is an α1 adrenergic receptor blocker. Tamsulosin, sold under the brand name Flomax among others, is a medication used to treat symptomatic benign prostatic hyperplasia (BPH) and chronic prostatitis and to help with the passage of kidney stones. The evidence for benefit with a kidney stone is better when the stone is larger. It is taken by mouth. Common side effects include dizziness, headache, sleeplessness, nausea, blurry vision, and sexual problems. Other side effects may include feeling lightheaded with standing and angioedema. Tamsulosin is an alpha blocker and works by relaxing muscles in the prostate.

Perioperative Tamsulosin for Treating Voiding Dysfunction Following Prostate Biopsy: A Multicenter, Randomized, Controlled, Open-Label Study

The goal of this clinical trial is to learn if the drug Tamsulosin Hydrochloride works to treat urination difficulties after a prostate biopsy in men.The main questions it aims to answer are:
* Does Tamsulosin Hydrochloride lower the rate of Acute Urinary Retention (inability to urinate) after a prostate biopsy?
* Does Tamsulosin Hydrochloride improve participants' urination symptoms, quality of life, urine flow rate, and post-void residual urine volume?
Researchers will compare the drug group to a control group (receiving no preventive medication) to see if Tamsulosin Hydrochloride works to prevent urination problems.
Participants will:
* Be randomly assigned to either take Tamsulosin Hydrochloride or receive no preventive medication.
* If in the drug group, take one capsule of Tamsulosin Hydrochloride every night, starting 3 days before the biopsy and continuing until 6 days after the biopsy (10 doses total).
* Undergo a standard prostate biopsy procedure (either through the rectum or perineum).
* Return to the clinic 7 days after the biopsy for a follow-up checkup, which will include questions about their symptoms (IPSS and QoL scores) and tests to measure urine flow and bladder emptying.

Intermittent (Every-Other-Day) vs Daily Tamsulosin for Men With Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia (LUTS/BPH) : A Multicenter, Assessor-Blinded, Randomized Non-Inferiority Trial. Arab Randomized Assessment of BPH Treatment (ARAB Trial)

Background:
Lower urinary tract symptoms (LUTS) are common in aging men, most often due to benign prostatic hyperplasia (BPH), and significantly impair quality of life. α1-adrenoceptor antagonists are first-line therapy, with tamsulosin being the most widely prescribed. However, ejaculatory dysfunction (EjD) is a frequent adverse effect that negatively affects adherence. Optimal dosing strategies that maintain urinary efficacy while reducing EjD are not well defined, and current guidelines provide no recommendations regarding alternate-day dosing.
Patients and Methods:
This multicenter, randomized, open-label, assessor-blinded, parallel-group, non-inferiority trial will enroll men aged ≥50 years with LUTS/BPH and baseline IPSS ≥8. Participants will be randomized 1:1 to receive tamsulosin 0.4 mg once daily or every other day for 24 weeks. The primary endpoint is change in International Prostate Symptom Score (IPSS) from baseline to Week 24. Non-inferiority will be concluded if the upper bound of the two-sided 95% confidence interval (CI) for the between-group difference in mean IPSS change (EOD - Daily) is ≤ +3 points.
The key secondary endpoint is change in Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD) total score from baseline to Week 24, tested for superiority only if IPSS non-inferiority is established. Additional secondary endpoints include maximum urinary flow rate (Qmax), post-void residual volume (PVR), IPSS-Quality of Life score, and ejaculatory adverse-event rates.
Sample Size and Analysis:
Assuming an SD of 6 for IPSS change, a non-inferiority margin of +3, one-sided α of 0.025, and 90% power, approximately 85 evaluable patients per arm are required for the primary endpoint. To ensure adequate power for EjD outcomes and allow for 20% attrition, 144 participants per arm (288 total) will be randomized. Analyses will follow the intention-to-treat principle with per-protocol sensitivity analyses. Primary inference will use ANCOVA or MMRM adjusted for baseline score, age, and study site, with multiple imputation for missing data.
Expected Outcomes:
This trial will provide the first adequately powered multicenter evidence on whether every-other-day tamsulosin preserves non-inferior LUTS control while improving ejaculatory outcomes, potentially supporting a simple and cost-effective strategy to enhance tolerability and adherence in men with LUTS/BPH.

Clonidine-induced tension changes in guinea pig thoracic aorta: roles of α1L-adrenoceptors, L-type voltage-dependent Ca2+ channels, and K+ channels

Article

Author: Yoshioka, Kento ; Ono, Ryusei ; Matsuyama, Yusuke ; Yashiro, Ayano ; Hong, Qianghaodi ; Kato, Daiki ; Gohara, Minori ; Tanaka, Yoshio ; Obara, Keisuke

We pharmacologically analyzed clonidine-induced tension changes in endothelium-denuded guinea pig thoracic aorta (GP-TA). Clonidine alone produced little change in basal tension; however, in the presence of tetraethylammonium (TEA) or Ba²⁺, it elicited a pronounced contraction that was almost completely abolished by verapamil. In contrast, phenylephrine alone evoked a robust contraction, which was also further enhanced in the presence of Ba²⁺; this Ba²⁺-potentiated component was nearly abolished by verapamil. The Ba²⁺-enhanced clonidine-evoked contraction was insensitive to the α₂-adrenoceptor (AR) antagonist idazoxan but was competitively inhibited by the α₁-AR antagonists prazosin and tamsulosin, yielding pA₂ values of 8.26 and 9.92, respectively. Clonidine competitively inhibited phenylephrine-induced contraction, with a pA₂ value of 5.67 in the presence of verapamil. Moreover, clonidine suppressed the sustained component of the phenylephrine response; this inhibition was attenuated by Ba²⁺ but remained unchanged in the presence of verapamil. These findings indicate that, in GP-TA, clonidine acts as a biased and partial agonist primarily at α_1L-ARs, promoting Ca²⁺ influx through L-type voltage-dependent Ca²⁺ channels (VDCCs). These L-type VDCC-mediated responses are negatively regulated by Ba²⁺-sensitive K⁺ channels. In addition, clonidine itself appears to directly or indirectly activate Ba²⁺-sensitive K⁺ channels, thereby suppressing the α_1L-AR-L-type VDCC functional coupling.

Platelet Lymphocyte Ratio and Mean Platelet Volume as Predictive Biomarkers for Spontaneous Passage of Distal Ureteric Stones in Patients Undergoing Medical Expulsive Therapy

Article

Author: Vinayak, Ruchitha ; Dhruva, H M ; Patil, Santosh ; Negi, Kiran K ; Kundargi, Vinay S ; Patil, Siddanagouda ; Kumar, Gulshan

INTRODUCTION:

Urolithiasis is a prevalent clinical condition associated with considerable morbidity. Distal ureteric stones are frequently managed with medical expulsive therapy (MET); however, predicting spontaneous stone passage remains a clinical challenge. Inflammatory markers such as platelet-lymphocyte ratio (PLR) and mean platelet volume (MPV) may serve as useful indicators for assessing the likelihood of MET success. This study aims to evaluate the predictive value of PLR and MPV in determining the success of MET for distal ureteral stones.

MATERIALS AND METHODS:

This prospective observational study enrolled 121 patients with single distal ureteric stones (5-10 mm). All patients received tamsulosin 0.4 mg/day for two weeks. PLR and MPV were measured at baseline, one week, and two weeks. Spontaneous passage was confirmed by imaging at two weeks. Differences between stone passers (n=100) and non-passers (n=21) were analyzed. Logistic regression identified independent predictors of stone passage, and receiver operating characteristic (ROC) analysis determined diagnostic performance and optimal cut-offs.

RESULTS:

Stone passers had significantly higher MPV and lower PLR compared to non-passers at all time points (p<0.001). ROC analysis showed good predictive performance for PLR (AUC=0.84, cut-off 20.5) and MPV (AUC=0.87, cut-off 7.5 fL). Logistic regression identified stone size >7 mm (OR 0.42, p=0.03), PLR ≤ 20.5 (OR 3.62, p<0.001), and MPV >7.5 fL (OR 4.28, p<0.001) as independent predictors of spontaneous stone passage.

CONCLUSION:

PLR and MPV are significant, easily measurable hematological markers that can predict spontaneous passage of distal ureteric stones, aiding clinical decision-making and potentially reducing unnecessary interventions.

Does preoperative alpha-blocker use affect the results of flexible ureterorenoscopy?

Article

Author: Sanci, A ; Akinci, A ; Gogus, C ; Babayigit, M

OBJECTIVE:

To evaluate the effect of alpha-blocker therapy during flexible ureterorenoscopy (F-URS) on the treatment of upper urinary tract stones.

METHODS:

A retrospective analysis was conducted on 476 patients who underwent F-URS at the Department of Urology between January 2010 and January 2017. Data collected included alpha-blocker use, stone size, stone location, patient age and gender, success or failure of ureteral access sheath (UAS) placement, ability to reach the stone during the procedure, postoperative stone-free status, and complication rates. Patients were divided into two groups: alpha-blocker users (n = 90, 18.9%) and non-users (n = 386, 81.1%).

RESULTS:

No significant differences were observed in gender distribution (P = 0.86) or stone size (P = 0.21) between the two groups. Alpha-blocker users had a lower complication rate (P = 0.022), a higher rate of successful stone access during the procedure (P = 0.007), and a higher postoperative stone-free rate (P = 0.01) compared to non-users. Among alpha-blocker users, tamsulosin and silodosin were associated with higher stone clearance rates (P = 0.046 and P = 0.037, respectively).

CONCLUSIONS:

Alpha-blocker therapy during F-URS for upper urinary tract stones is associated with improved outcomes, including higher stone access rates, reduced complications, and increased stone-free rates. These findings suggest that alpha-blockers, particularly tamsulosin and silodosin, may enhance the efficacy and safety of F-URS.

Hanmi Pharmaceutical's 'Gugutams' to be Launched in Mexico as 'Aditams', Marking the Start of Full-Scale Latin America Expansion

Hanmi Pharm Begins Local Sales of Urological Product 'Aditams' in Mexico with Partner 'Laboratorios Silanes' Launch completed in February, Hanmi Pharm's Third Product to Enter Latin America Aditams, The First Urological Combination Drug for OPG and ED Exported to Mexico SEOUL, South Korea, April 2, 2025 /PRNewswire/ -- Hanmi Pharmaceutical's combination therapy for Obstructive Prostatic Growth (OPG) caused by Benign Prostatic Hyperplasia (BPH) and Erectile Dysfunction (ED), Gugutams, is entering the Mexican market under the local brand name "Aditams." Continue Reading Aditams Hanmi Pharmaceutical announced that it has completed the launch of Aditams in Mexico under the export agreement signed in October 2020 with the Mexican pharmaceutical company 'Laboratorios Silanes'. Under the agreement, Hanmi Pharmaceutical plans to export Gugutams to the Mexican market for a period of seven years, starting in February 2025. Gugutams, developed by Hanmi Pharmaceutical, is the world's first urological combination therapy combining two active ingredients: tamsulosin, a treatment for Obstructive Prostatic Growth (OPG), and tadalafil, a treatment for erectile dysfunction (ED). It is also noteworthy as the first prescription drug in Korea to apply Poly-Cap technology, which integrates multiple active ingredients into a single capsule. Laboratorios Silanes, a leading pharmaceutical company in Mexico founded in 1943, is committed to providing innovative healthcare solutions and driving rapid growth in the industry. It has established itself as a key player in the Latin American pharmaceutical market through its robust distribution network and strategic collaborations with global partners. Silanes previously collaborated with Hanmi Pharmaceutical in 2023 to successfully introduce the hypertension and dyslipidemia combination treatment 'Amosartan Q', under the local brand 'Lodarta' and in 2024 to introduce the combination hypertension treatment 'Amosartan Plus' under the local brand 'Bicartial-CTD'. Following these products, Gugutams, under the local brand 'Aditams', becomes Hanmi Pharmaceutical's third product in the Latin American region. Aditams, as the first urological combination therapy to enter the Mexican market, is expected to offer a new treatment option for patients suffering from both Obstructive Prostatic Growth (OPG) and erectile dysfunction (ED). By managing both conditions with a single medication, it significantly enhances patient convenience and maximizes therapeutic efficacy. Hanmi continues to focus on expanding its partnerships in emerging markets such as the Middle East and Latin America, in addition to its established presence in developed markets like North America and Japan. The company aims to leverage strategic partners like Laboratorios Silanes as key footholds to broaden its product portfolio and regional reach. Park Jae-hyun, CEO of Hanmi Pharmaceutical, stated, "As the first urological combination therapy to enter the Mexican market, Gugutams is expected to present a new treatment paradigm for local patients." He added, "Through this collaboration with Laboratorios Silanes, we aim to solidify Hanmi Pharmaceutical's presence in the Latin American market and leverage this as a foundation to further strengthen our competitiveness in the global pharmaceutical industry."
