Review
PURPOSE OF REVIEW
Aim of our systematic review is to evaluate and summarize the efficacy and safety of tadalafil alone or in combination with tamsulosin for the management of lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and erectile dysfunction (ED).
RECENT FINDINGS
Daily tadalafil, in particular 5 mg, according to retrieved studies, appears to be both safe and effective in treating LUTS/BPH and ED, compared with placebo or tamsulosin. The combination of daily tadalafil 5 mg and tamsulosin 0.4 mg allows a better improvement of LUTS compared with both the monotherapies, even if with an increased, but acceptable and tolerated, adverse events rate. After discontinuation of tamsulosin or tadalafil in patients previously treated with their combination, the improvement of LUTS retains significance compared with baseline. Tadalafil 5 mg should be considered a primary treatment option for patients with LUTS/BPH and ED. Evidence highlight an excellent tolerability, safety, and effectiveness profile, both alone or in combination with tamsulosin 0.4 mg. A better efficacy on LUTS relief has been observed for combination therapy, preserving also sexual function. The further switch to monotherapy allows to preserve LUTS relief, but tadalafil only is able to retain ED improvement. Our results support the evidence for a more and more tailored and modular LUTS treatment.

Review
In this article, we review the primary medical treatments of BPH-associated male LUTS, with a focus on physiology, indications, and side effects. We cover selective alpha-1 antagonists, anticholinergics, PDE5 inhibitors, 5-alpha reductase inhibitors, and beta-3 agonists. Through a review of the literature, we provide our clinical pathway for the medical management of BPH, generally starting with tamsulosin in most men and progressing to combination therapy based on patient's response and symptoms.

Randomized Controlled Trial
IMPORTANCE
Urinary stone disease is a common presentation in the emergency department, and α-adrenergic receptor blockers, such as tamsulosin, are commonly used to facilitate stone passage.
OBJECTIVE
To determine if tamsulosin promotes the passage of urinary stones within 28 days among emergency department patients.
DESIGN, SETTING, AND PARTICIPANTS
We conducted a double-blind, placebo-controlled clinical trial from 2008 to 2009 (first phase) and then from 2012 to 2016 (second phase). Participants were followed for 90 days. The first phase was conducted at a single US emergency department; the second phase was conducted at 6 US emergency departments. Adult patients were eligible to participate if they presented with a symptomatic urinary stone in the ureter less than 9 mm in diameter, as demonstrated on computed tomography.
INTERVENTIONS
Participants were randomized to treatment with either tamsulosin, 0.4 mg, or matching placebo daily for 28 days.
MAIN OUTCOMES AND MEASURES
The primary outcome was stone passage based on visualization or capture by the study participant by day 28. Secondary outcomes included crossover to open-label tamsulosin, time to stone passage, return to work, use of analgesic medication, hospitalization, surgical intervention, and repeated emergency department visit for urinary stones.
RESULTS
The mean age of 512 participants randomized to tamsulosin or placebo was 40.6 years (range, 18-74 years), 139 (27.1%) were female, and 110 (22.8%) were nonwhite. The mean (SD) diameter of the urinary stones was 3.8 (1.4) mm. Four hundred ninety-seven patients were evaluated for the primary outcome. Stone passage rates were 50% in the tamsulosin group and 47% in the placebo group (relative risk, 1.05; 95.8% CI, 0.87-1.27; P = .60), a nonsignificant difference. None of the secondary outcomes were significantly different. All analyses were performed according to the intention-to-treat principle, although patients lost to follow-up before stone passage were excluded from the analysis of final outcome.
CONCLUSIONS AND RELEVANCE
Tamsulosin did not significantly increase the stone passage rate compared with placebo. Our findings do not support the use of tamsulosin for symptomatic urinary stones smaller than 9 mm. Guidelines for medical expulsive therapy for urinary stones may need to be revised.

Pakistan Journal of Medical Sciences 2022To study the therapeutic effects of combined tamsulosin hydrochloride and terazosin treatment for patients with chronic prostatitis Type-III b.
OBJECTIVES
To study the therapeutic effects of combined tamsulosin hydrochloride and terazosin treatment for patients with chronic prostatitis Type-III b.
METHODS
This study involved 180 patients with chronic prostatitis Type-III b treated between January 2018 and December 2020 conducted at Nanhua Hospital Affiliated to Nanhua University. Patients were randomly divided into two equal groups: one receiving oral terazosin hydrochloride tablets only (control group), and one orally receiving both tamsulosin hydrochloride sustained-release tablets and terazosin hydrochloride tablets (observation group). Outcome measurements included symptom scoring, inflammatory cytokine levels, as well as white blood cell and lecithin body counts in the prostatic fluid.
RESULTS
After 30 days of treatment, the observation group showed greater treatment effectiveness (86.67% vs. 73.33%, P<0.05). QLS, USS, PS, and NIH-CPSI symptom scores were lower in the observation group than the control group (P<0.05). No differences in adverse event distribution and incidence were noted. EPS IL-2 increased more in the observation group, while PGE-2, MIP-1α, and MIP-2 decreased more in the observation group. WBC levels decreased more in the observation group, while lecithin body levels increased more in the observation group.
CONCLUSION
The combination of tamsulosin hydrochloride and terazosin for the treatment of patients with chronic prostatitis Type-III b has a significant effect. This approach reduced patient symptoms, lowered inflammatory biomarkers, and generally improved quality of life. This approach appears to have clinical value worthy of future investigation.

This study aimed to prepare tamsulosin hydrochloride (HCl)-loaded in situ gelling formulation by using hydroxypropyl methylcellulose (HPMC), gellan gum, poloxamer 188, and benzalkonium chloride. Physicochemical evaluation of formulations included determination of pH, viscosity, gelation time, gel strength, drug content, and sterility. In silico study was performed to analyze interactions between polymers, drug, and mucin glycoprotein. In vitro degradation time, drug release, ex vivo mucoadhesion time, permeation, in vivo pharmacokinetics, and stability studies were performed to assess the formulation. Formulations were transparent and displayed acceptable physicochemical attributes. Tamsulosin HCl and polymers interacted via non-covalent interactions. HPMC formed hydrogen bonds, hydrophobic and van der Waals interactions with mucin protein while the drug formed hydrogen bonds only. Gel formulation degraded in simulated nasal fluid within 24 h. In situ gelling formulation showed 83.8 ± 1.7% drug release and remained adhered to the mucosa for 24.5 ± 1 h. A higher (~ 1.85 times) drug permeation was recorded through mucosa within 6 h by in situ gelling formulation when compared to control counterparts (aqueous solution of drug and in situ gelling formulation without poloxamer 188). Nasal administration of tamsulosin HCl by using in situ gelling formulation led to a ~ 3.3 and ~ 3.5 times, respectively, higher Cmax (maximum plasma concentration) and AUC (total area under the curve) than the orally administered aqueous solution. Relative bioavailability of drug delivered by nasal in situ gelling formulation was 3.5 times the oral counterpart. These results indicated that the prepared in situ gelling formulation can act as a promising candidate for systemic administration of tamsulosin HCl.

Review
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. Results: In total, 14 studies were included in our analysis. The size of ureteral stones was <1 cm. Compared with tamsulosin, silodosin resulted in a significantly higher stone expulsion rate (p < 0.01, odds ratio (OR) = 2.42, 95% confidence interval (CI) = 1.91 to 3.06, I2 = 0%) and significantly shorter stone expulsion time (p < 0.01, mean difference = −3.04, 95% CI = −4.46 to −1.63, I2 = 89%). The total complication rate did not significantly differ between silodosin and tamsulosin (p = 0.33, OR = 1.15, 95% CI = 0.87 to 1.52, I2 = 7%). Conclusions: Compared with tamsulosin, silodosin resulted in significantly better expulsion of ureteral stones <1 cm. The total complication rate did not significantly differ between silodosin and tamsulosin. Thus, silodosin may be superior to tamsulosin for MET of ureter stones <1 cm.

Tamsulosin hydrochloride is one of the most potent drugs for treatment of benign prostatic hyperplasia (BPH), however, the efficacy of tamsulosin hydrochloride varies among individuals. In this study, we measured the maximum serum concentration (Cmax) of tamsulosin hydrochloride in 182 of BPH patients and found remarkable individual variability. To investigate the genetic factors that regulate pharmacokinetics of tamsulosin hydrochloride, we conducted a genome-wide association study in these 182 BPH patients. As a result, rs16902947 on chromosome 5p13.2, rs7779057 on 7q22.3, rs35681285 on 7p21.2 and rs2122469 on 8p21.3 indicated possible associations with Cmax of tamsulosin hydrochloride (P=1.29 × 10(-7), 2.15 × 10(-7), 4.35 × 10(-7) and 7.03 × 10(-7), respectively), although these single-nucleotide polymorphisms (SNPs) did not reach the genome-wide significance threshold after Bonferroni correction. As these associated SNPs showed additive effects on serum tamsulosin hydrochloride concentration, we defined the 'Cmax prediction index' based on genotypes of these SNPs. This index clearly associated with Cmax values (P=4.5 × 10(-6)), indicating the possible roles of these four variants in tamsulosin hydrochloride pharmacokinetics. Our findings would partially explain the variability of the response to the tamsulosin hydrochloride treatment.
