Androgenetic alopecia is the most common hair loss, characterized by a chronic and progressive course and a significant psychosocial burden. The aim of this study was to provide a comparative analysis of current international guidelines and expert consensus statements on the treatment of androgenetic alopecia and to summarize their applicability in clinical practice. A literature search was performed in the PubMed database to identify English-language guidelines and expert recommendations published between 2015 and 2025. The included documents were analyzed narratively and compared based on therapeutic approaches. Conventional treatments, including topical minoxidil and 5-alpha-reductase inhibitors, remain the cornerstone of therapy. More recent recommendations increasingly support the use of low-dose oral minoxidil and dutasteride; however, their position varies across guidelines. The role of procedural therapies also differs, mainly due to limited evidence. Differences between recommendations are primarily driven by variability in levels of evidence and the evolving new therapies. In clinical practice, an individualized, multimodal treatment strategy combined with regular follow-up is essential. The management of androgenetic alopecia is a rapidly evolving field requiring personalized therapeutic decisions. In clinical practice, a personalized combined treatment strategy and regular follow-up are of paramount importance. Orv Hetil. 2026; 167(35): 1385-1393.

This study aimed to compare the efficacy of tamsulosin monotherapy versus tamsulosin combined with tolterodine for facilitating the expulsion of distal ureteral stones. A prospective, randomized controlled trial was conducted between 2022 and 2023 at the Urology Clinic of Imam Reza Hospital, Ardabil. A total of 120 patients diagnosed with distal ureteral stones (4-10 mm in size) were randomized into two groups: Group A received 0.4 mg tamsulosin daily, and Group B received 0.4 mg tamsulosin daily plus 2 mg tolterodine twice daily. Treatment duration was up to 4 weeks. Primary outcomes included stone expulsion rate and expulsion time. Secondary outcomes comprised pain control (visual analog scale, VAS), analgesic requirement, and incidence of side effects. The two groups were comparable at baseline in terms of demographic and stone characteristics. The stone expulsion rate was significantly higher in Group B (tamsulosin + tolterodine) at 83.3% (50/60) compared to Group A (tamsulosin alone) at 66.7% (40/60) (p = 0.03). The mean stone expulsion time was also significantly shorter in Group B (10.5 ± 3.2 days) compared to Group A (14.8 ± 4.1 days) (p < 0.001). Patients in Group B reported lower mean pain scores (VAS) and required less rescue analgesia. The incidence of adverse effects was comparable between the groups, with dry mouth being slightly more common in Group B. The combination of tamsulosin and tolterodine demonstrated superior efficacy in terms of stone expulsion rate and reduced expulsion time for distal ureteral stones compared to tamsulosin monotherapy. This combination therapy may offer a more effective medical expulsive therapy option for patients with distal ureteral calculi.

Atypical antipsychotics, including lurasidone, are increasingly prescribed due to their perceived lower risk of side effects. We present the case of a 65-year-old woman with longstanding BPAD who developed symptoms of urinary retention (UR), confirmed on bladder ultrasound, soon after beginning lurasidone monotherapy for bipolar affective disorder (BPAD) management. Despite dose reduction and addition of tamsulosin, symptoms of UR persisted and only resolved with cessation of lurasidone. The causal relationship between lurasidone and UR was assessed using the Naranjo Adverse Drug Reaction (ADR) Probability Scale, yielding a score of 8, indicating a highly 'probable' ADR. A literature review revealed only two prior reports of lurasidone-associated UR, highlighting the rarity of this presentation. This case underscores the need for clinicians to remain vigilant for UR in patients prescribed lurasidone, or other atypical antipsychotics, despite their generally favourable side effect profile. Early recognition and management are critical to prevent complications and ensure appropriate ongoing treatment of BPAD.

Background/Objectives: Tamsulosin extended-release (ER) formulations minimize peak-related vasodilatory adverse events in benign prostatic hyperplasia (BPH) treatment. This study assessed the pharmacokinetics and bioequivalence of a generic tamsulosin 0.4 mg ER formulation against the innovator under fasting and fed conditions. Methods: Two randomized, open-label, four-period crossover, single-dose trials were conducted in healthy Mexican males. Subjects received treatment following a 10 h fast or a high-fat meal, with a 7-day washout. Plasma tamsulosin was quantified over 72 h via LC-MS/MS. An exploratory in vitro-in vivo correlation (IVIVC) analysis was also performed. Results: Analyses included 32 (fasting) and 58 (fed) subjects. In both states, 90% confidence intervals for Cmax, AUC0-t, and AUC0-∞ geometric mean ratios fell entirely within the 80.00-125.00% bioequivalence limits. The formulations showed comparable dissolution (f2 = 92.47), with numerical deconvolution proving most predictive in exploratory IVIVC. Notably, the pharmacokinetic profile of the test formulation was consistent with maintained controlled drug release under both dietary conditions and showed no pharmacokinetic evidence of food-induced dose dumping. Both formulations were well-tolerated; all adverse events were mild, with no clinically significant orthostatic hypotension observed. Conclusions: The generic tamsulosin 0.4 mg ER formulation is bioequivalent to the reference product in both fasting and fed states. Its structural robustness prevents dose dumping, ensuring a favorable hemodynamic safety profile. Comparable dissolution and IVIVC findings further support their reliability in vivo performance and therapeutic interchangeability. ClinicalTrials.gov identifiers: NCT07698288 and NCT07698275.

Hair follicle homeostasis is influenced by hormonal pathways, the scalp microenvironment, and environmental stressors such as pollution, UV radiation, and oxidative stress. Elissara®, a polyphenol-enriched botanical ingredient, has shown benefits for scalp moisturization, barrier function, sebum regulation, and redness. Building on these scalp-level benefits, we investigated Elissara's effects on follicular signaling, survival-associated biomarkers, oxidative damage, and androgen-related pathways as potential contributors to follicular health, using in silico, in vitro, and ex vivo models. Molecular docking (AutoDock Vina) of the main Elissara bioactives (oleuropein, hydroxytyrosol, verbascoside, carnosic acid, carnosol, and quercetin) identified SRD5A2 as a favorable predicted target, with individual binding energies ranging from -8.70 to -9.73 kcal/mol, approaching finasteride/dutasteride reference values. As an exploratory approach, simultaneous multi-ligand docking showed favorable global docking outputs for several targets, indicating that multiple bioactives could be structurally accommodated within complementary regions of the binding site. In human follicle dermal papilla cells, Elissara significantly increased BrdU incorporation to 245.70% of control at 0.002% and reduced SRD5A2 protein levels by 18.48% at 0.006%. In human scalp explants, Elissara at 200 µg/mL increased β-catenin, Bcl-2, and collagen IV under basal conditions and counteracted acute PM2.5/UVA-induced alterations in β-catenin, Ki67-positive cells, Bcl-2, IGF-1, collagen IV, and protein carbonylation. Together, these findings support the potential of Elissara as a promising nutricosmetic ingredient for supporting follicular resilience through multiple follicle-relevant pathways. Clinical studies assessing hair growth outcomes are needed to determine whether these preclinical findings translate into measurable benefits.
