BACKGROUND: To compare the effects of different alpha-blocker regimes on acute urinary retention (AUR) and the success rate of trial without catheter (TWOC) among patients with AUR secondary to benign prostatic hyperplasia (BPH) to determine the most effective regime. METHODS: A comprehensive literature search was performed using PubMed/Medline, Embase, and Cochrane Library up to June 2021. Studies that compared successful TWOC rates between each alpha-blocker regime in patients with AUR secondary to BPH were included...

BACKGROUND: Zinner syndrome is a rare congenital anomaly featuring a unilateral seminal vesicle cyst and ipsilateral renal agenesis. While the majority of affected patients are asymptomatic and followed with conservative management, others have symptoms such as micturition, ejaculatory difficulties, and/or pain, thus may require treatment. These patients often undergo an invasive procedure as first-line treatment, such as transurethral resection of the ejaculatory duct, or aspiration and drainage, which reduces pressure within the seminal vesicle cyst, or surgical resection of the seminal vesicle...

OBJECTIVE: The present retrospective study evaluates the effectiveness and tolerability of alpha-blockers as monotherapy in patients with benign prostatic hyperplasia associated with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: A total of 335 male patients >50 years were categorized into four groups (Alfuzosin: 166, Silodosin: 67, Tamsulosin: 70, Prazosin: 32). The efficacy evaluated as a change in International Prostate Symptom Score (IPSS), peak flow rate (Qmax), residual urine volume, and relief from LUTS, and tolerability of the various alpha-blockers was assessed across the study group...

The stability of active pharmaceutical ingredients (APIs) and formulations has become a major chemistry, manufacturing, and control (CMC) concern in the pharmaceutical industry because it can determine the feasibility of research and development, the development period, and the development costs of a certain formulation. To streamline the research and development of pharmaceutical products and create useful pharmaceutical products at an early stage, a technology that predicts the stability of formulations at an early stage and with a high degree of accuracy is needed...

BACKGROUND: Patients on alpha-blockers (ABs) treatment may have an increased risk of adverse events (AEs). Aim of our study was to compare real-life data on neuro-vascular and sexual AEs associated with ABs based on Eudra-Vigilance reported AEs. METHODS: Eudra-Vigilance (EV) database is the system for managing and analyzing information on suspected adverse reactions to medicines which have been authorized or being studied in clinical trials in the European Economic Area (EEA)...

OBJECTIVE: To our knowledge, there is no study in the literature so far to investigate the effect of silodosin therapy on the ureteric jet parameters. Therefore, the objective of this study was to investigate the effect of silodosin 8 mg/day for medical therapy of lower urinary tract symptoms (LUTS) on the color flow Doppler parameters and patterns of the ureteric jets. PATIENTS AND METHODS: This prospective cohort study included 34 male patients who presented to our outpatient clinic with the complaint of lower urinary tract symptoms (LUTS) and received silodosin 8 mg once a day as medical therapy...

OBJECTIVE: To compare the efficacy of Tamsulosin, Silodosin and Tadalafil as a medical expulsive therapy for treatment of distal ureteral calculi. PATIENTS AND METHODS: Over a period of 6 months (January 2022 to June 2022) this prospective randomized study was conducted on 170 patients with distal ureteric stone ≤ 10 mm. Patients were randomly divided into three groups. Patients in group A received Tamsulosin 0.4mg, in group B received Silodosin, and in group C receive Tadalafil 5 mg...

This meta-analysis investigated the efficacy and adverse drug reactions (ADRs) of three different adrenergic alpha-antagonists during the treatment of pediatric ureteral stones. Studies were retrieved from MEDLINE, EMBASE, and the Cochrane Controlled Trial Registry until January 2022. We identified 7 articles, including six RCTs and one cohort study. 610 children received either adrenergic alpha-antagonists or placebo. The results confirmed that the three different adrenergic alpha-antagonists could significantly increase the ureteral calculi expulsive rate and shorten the ureteral calculi expulsive time, regardless of the size of the stone "<5 mm" or "5-10 mm"...

To evaluate the efficacy and safety of medical expulsive therapy (MET) for ureteral stones in pediatric patients, Cochrane, PubMed, Web of Science, Scopus, and the reference list of retrieved studies were searched up to September 2022 to identify RCTs on the efficacy of MET. The protocol was prospectively registered at PROSPERO (CRD42022339093). Articles were reviewed, data were extracted by two reviewers, and the differences were resolved by the third reviewer. The risk of bias was assessed using the RoB2...

INTRODUCTION: Tamsulosin is the most commonly used medical expulsive therapy (MET). However, it does not alleviate ureteral colic. It is important to develop MET that can reduce ureteral colic while maintaining a high stone clearance rate. Silodosin is an α1A adrenoceptor with high affinity and selectivity for the distal ureter, which may reduce ureteral colic and enable stone expulsion for distal ureteral stones. Therefore, we performed this systematic review and meta-analysis to evaluate the efficacy of silodosin as MET and its role in reducing ureteral colic among patients with distal ureteral stones...

We examined whether the α1L -adrenoceptor (AR), which shows low affinity (pA2  < 9) for prazosin (an α1 -AR antagonist) and high affinity (pA2  ≈ 10) for tamsulosin/silodosin (α1A -AR antagonists), is involved in phenylephrine-induced contractions in the guinea pig (GP) thoracic aorta (TA). Intracellular signaling induced by α1L -AR activation was also examined by focusing on Ca2+ influx pathways. Tension changes of endothelium-denuded TAs were isometrically recorded and mRNA encoding α-ARs/Ca2+ channels and their related molecules were measured using RT-quantitative PCR...

PURPOSE: Urolithiasis is a common urinary tract disease with growing prevalence. Alpha1-adrenoceptors (α1-ARs) are abundant in ureteral smooth muscle, distributed with different α1-AR subtypes. α1D-AR is the most widely distributed in the ureter. However, the effect of α1D-AR blockade on ureteric contraction remains unknown. MATERIALS AND METHODS: We dissected smooth muscle tissues (3 mm×3 mm) from the rat bladder and human ureter, tied silk strips on both tissue ends, and measured contraction in an organ bath chamber...

INTRODUCTION: According to domestic and foreign publications, benign prostatic hyperplasia (BPH) is one of the most common urological diseases among older men, which prevalence reaches 50% by the age of 60. AIM: To analyze the efficiency of the use of the alpha1-blocker silodosin at a dose of 8 mg a day in comorbid patients with lower urinary tract symptoms (LUTS), associated with BPH. MATERIALS AND METHODS: A total of 197 comorbid patients with LUTS/BPH were included in the study...

BACKGROUND: European association of urology (EAU) recommended α- blockers for managing distal ureteric stones in the paediatric population. This paper will help to understand the efficacy of Silodosin as a medical expulsive agent for distal ureteric stones in children, along with the required time duration of stone expulsion. METHODS: Forty participants were enrolled and evaluated for complaints, pain severity, associated symptoms, and ultrasound was done to confirm the position and size of the distal stone...

Some years ago, excipients were considered inert substances irrelevant in the absorption process. However, years of study have demonstrated that this belief is not always true. In this study, the reasons for a bioequivalence failure between two formulations of silodosin are investigated. Silodosin is a class III drug according to the Biopharmaceutics Classification System, which has been experimentally proven by means of solubility and permeability experiments. Dissolution tests have been performed to identify conditions concordant with the non-bioequivalent result obtained from the human bioequivalence study and it has been observed that paddles at 50 rpm are able to detect inconsistent differences between formulations at pH 4...

Background and Objectives : This systematic review and meta-analysis of randomized controlled trials was performed to compare the therapeutic effects and safety profiles of silodosin and tamsulosin for medical expulsive therapy (MET) of ureteral stones. Materials and Methods: We searched PubMed, EMBASE, the Cochrane Library, and Web of Science to identify articles published before July 2022 that described randomized controlled trials comparing silodosin and tamsulosin for MET of ureteral stones. Endpoints were stone expulsion rate, stone expulsion time, and total complication rate...

Silodosin is a single isomer selective α1 -adrenoreceptor antagonist used for the treatment of benign prostatic hyperplasia. In order to control the enantiomeric purity of the drug a capillary electrophoresis method was developed that is applicable to the analysis of drug substance as well as pharmaceutical formulations. Method development followed a quality by design strategy. After selection of carboxymethyl-β-cyclodextrin as suitable chiral selector and the starting conditions in the scouting phase, a two-level full factorial design was applied to identify the critical process parameters...

Purpose: Bladder Pain Syndrome/Interstitial Cystitis (BPS/IC) is a bladder-related chronic inflammatory disease. Data indicate that stress enhances the excitability of bladder nociceptors through the stimulation of alpha1A-adrenoceptors. Stress is known to play a crucial role in BPS/IC patients. We aimed to assess the efficacy and safety of daily silodosin in refractory BPS/IC female patients and its correlation with stress coping. Materials and Methods: An open-label trial was conducted with 20 refractory BPS/IC patients...

Selective α1-blockers are commonly administered to patients with lower urinary tract syndrome and benign prostatic hyperplasia, but may increase the risk of intraoperative floppy iris syndrome (IFIS). The purpose of this study aimed to clarify the risk of IFIS among various selective α1-blockers. Four databases were searched for prospective studies comparing alpha-1-antagonists. Data were pooled using the consistency model, and used risk ratio (RR) and mean difference (MD) for IFIS and pupil diameter, respectively...
