Abstract
INTRODUCTION Bladder storage dysfunction is associated with low quality of life in men and remains a challenging field in pharmacotherapy because of low persistence followed by patient-perceived lack of efficacy and adverse effects. The persistent desire for the development of novel pharmacotherapy is evident, leading to numerous research efforts based on its pathophysiology. AREAS COVERED This review describes the pathophysiology, current pharmacotherapeutic strategies, and emerging novel drugs for male bladder storage dysfunction. The section on emerging pharmacotherapy provides an overview of current research, focusing on high-potential target molecules, particularly those being evaluated in ongoing clinical trials. EXPERT OPINION As pharmacotherapies targeting alpha-adrenergic, beta-adrenergic, and muscarinic receptors - the current primary targets for treating male bladder storage dysfunction - have demonstrated insufficient efficacy and side effects, researchers are exploring various alternative molecular targets. Numerous targets have been identified as central to regulating bladder afferent nerve activity, and their pharmacological effects and potential have been evaluated in animal-based experiments. However, there is a limited number of clinical trials for these new pharmacotherapies, and they have not demonstrated clear superiority over current treatments. Further research is needed to develop new effective pharmacotherapies for bladder storage dysfunction in men.

Junior MSC, Bezerra AG, Curado DF, Gregório RP, Galduróz JCF. Preliminary investigation of the administration of biperiden to reduce relapses in individuals with cocaine/crack user disorder: A randomized controlled clinical trial. Pharmacol Biochem Behav 2024; 237:173725. [PMID: 38340989 DOI: 10.1016/j.pbb.2024.173725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 01/17/2024] [Accepted: 02/05/2024] [Indexed: 02/12/2024]
Abstract
BACKGROUND Several studies have demonstrated that ACh modulates the dopaminergic circuit in the nucleus accumbens, and its blockade appears to be associated with the inhibition of the reinforced effect or the increase in dopamine caused by cocaine use. The objective of this study was to evaluate the effect of biperiden (a muscarinic receptor antagonist with a relatively higher affinity for the M1 receptor) on crack/cocaine use relapse compared to a control group that received placebo. METHODS This study is a double-blind, randomized, placebo-controlled clinical trial. The intervention group received 2 mg of biperiden, 3 times a day, for a period of 3 months. The control group received identical placebo capsules, at the same frequency and over the same period. All participants were followed for a period of six months. RESULTS The sample comprised 128 people, with 61 in the control group and 67 in the biperiden group. Lower substance consumption was observed in the group that received biperiden treatment two (bT2 = -2.2 [-3.3; -1.0], p < 0.001) and six months (bT4 = -6, 2 [-8.6; -3.9], p < 0.001) after the beginning of the intervention. The biperiden group had a higher latency until a possible first day of consumption, in the same evaluation periods (bT2 = 0.26 [0.080; 0.44], p = 0.004; bT4 = 0.63 [0.32; 0.93], p < 0.001). CONCLUSIONS Despite the major limitations of the present study, the group that received biperiden reduced the number of days of cocaine/crack use and showed an increase in the latency time for relapse. More studies are needed to confirm the utility of this approach.

Hsiao SM. Predictors of non-persistence in women with overactive bladder syndrome. Sci Rep 2024; 14:7499. [PMID: 38553529 PMCID: PMC10980757 DOI: 10.1038/s41598-024-58036-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 03/25/2024] [Indexed: 04/02/2024] Open
Abstract
Persistence is important for the success in the treatment of women with overactive bladder syndrome (OAB). We aimed to identify the predictors of non-persistence in women with OAB after first-line medical treatment. All consecutive women with OAB (n = 608), who underwent urodynamic studies and received first-line medical treatment (5 mg of solifenacin or 25 mg of mirabegron per day) in a referral medical center, were reviewed. Mirabegron (hazard ratio [HR] = 0.711) was associated with a higher persistence rate, compared to solifenacin. Mirabegron treatment (HR = 0.269) was less likely to switch medication; however, a high Urogenital Distress Inventory score (HR = 1.082) was more likely to switch medication. Furthermore, old age (HR = 1.050, especially for ≥ 75 years) and high voided volume (dL, HR = 1.420, especially for voided volume ≥ 250 ml) were associated with added medication at follow-up. Additionally, women with low parity (HR = 0.653, especially for parity ≤ 3) and a low Incontinence Impact Questionnaire (IIQ-7) score (HR = 0.828, especially for IIQ-7 score ≤ 7) were associated with improvement without medication. In conclusion, mirabegron can be considered as the first frontline treatment to increase the persistence rate and decrease the rate of switched medications, compared to solifenacin. In addition, combination therapy or higher-dose monotherapy could be used as the first front-line treatment for women ≥ 75 years of age or with ≥ 250 ml of voided volume.

A muscarinic receptor antagonist reverses multiple indices of diabetic peripheral neuropathy: preclinical and clinical studies using oxybutynin. Acta Neuropathol 2024; 147:60. [PMID: 38526612 DOI: 10.1007/s00401-024-02710-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/16/2024] [Accepted: 02/17/2024] [Indexed: 03/27/2024]
Abstract
Preclinical studies indicate that diverse muscarinic receptor antagonists, acting via the M1 sub-type, promote neuritogenesis from sensory neurons in vitro and prevent and/or reverse both structural and functional indices of neuropathy in rodent models of diabetes. We sought to translate this as a potential therapeutic approach against structural and functional indices of diabetic neuropathy using oxybutynin, a muscarinic antagonist approved for clinical use against overactive bladder. Studies were performed using sensory neurons maintained in vitro, rodent models of type 1 or type 2 diabetes and human subjects with type 2 diabetes and confirmed neuropathy. Oxybutynin promoted significant neurite outgrowth in sensory neuron cultures derived from adult normal rats and STZ-diabetic mice, with maximal efficacy in the 1-100 nmol/l range. This was accompanied by a significantly enhanced mitochondrial energetic profile as reflected by increased basal and maximal respiration and spare respiratory capacity. Systemic (3-10 mg/kg/day s.c.) and topical (3% gel daily) oxybutynin reversed paw heat hypoalgesia in the STZ and db/db mouse models of diabetes and reversed paw tactile allodynia in STZ-diabetic rats. Loss of nerve profiles in the skin and cornea of db/db mice was also prevented by daily topical delivery of 3% oxybutynin for 8 weeks. A randomized, double-blind, placebo-controlled interventional trial was performed in subjects with type 2 diabetes and established peripheral neuropathy. Subjects received daily topical treatment with 3% oxybutynin gel or placebo for 6 months. The a priori designated primary endpoint, significant change in intra-epidermal nerve fibre density (IENFD) in skin biopsies taken before and after 20 weeks of treatments, was met by oxybutynin but not placebo. Secondary endpoints showing significant improvement with oxybutynin treatment included scores on clinical neuropathy, pain and quality of life scales. This proof-of-concept study indicates that muscarinic antagonists suitable for long-term use may offer a novel therapeutic opportunity for treatment of diabetic neuropathy. Trial registry number: NCT03050827.

A Double-blind, Randomised Four-way Crossover Study to Compare the Effects of Fesoterodine 4 and 8 mg Once Daily and Qxybutynin 5 mg Twice Daily After Steady-state Dosing Versus Placebo on Cognitive Function in Overactive Bladder-wet Patients over the Age of 75 Years with Mild Cognitive Impairment. Eur Urol Focus 2024; 10:325-331. [PMID: 38402104 DOI: 10.1016/j.euf.2024.02.005] [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: 09/01/2023] [Revised: 12/19/2023] [Accepted: 02/14/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND AND OBJECTIVE There is a reported association between overactive bladder (OAB) treated with antimuscarinic drugs and an increased risk of a dementia diagnosis, although short-term data suggest that newer OAB antimuscarinics are cognitively safe. This study examined the cognitive safety of fesoterodine in older adults with mild cognitive impairment (MCI) and OAB. METHODS This four-way randomised crossover study examined the cognitive effects of fesoterodine 4 and 8 mg and oxybutynin 5 mg b.i.d. compared with placebo. Older adult patients with OAB and MCI were included. Treatment and washout periods were of 1-week duration, to reach steady-state drug levels. The primary outcome was continuity of attention at 1 and 4 h after the dose. The secondary outcomes included other cognitive domains, change in Montreal Cognitive Assessment score, and alertness. KEY FINDINGS AND LIMITATIONS Twenty-three patients completed the study (16 females and seven males). For the primary outcome, at 1 h after the dose, a trend towards worsening of continuity of attention was observed for fesoterodine 4 mg (p = 0.09) compared with placebo. At 4 h after the dose, a nonstatistically significant trend towards improvement compared with placebo was observed in the fesoterodine 4 mg group (p = 0.0633) compared with placebo. No differences were observed in any other treatment group at either time point. Apart from quality of working memory, associated with a statistically significant improvement with fesoterodine 4 mg, there was no difference in any comparison for other secondary outcomes. CONCLUSIONS Exposure to steady-state dosing of fesoterodine 4 and 8 mg or oxybutynin 5 mg b.i.d. was not associated with any detectable effect on cognitive function using a sensitive battery of cognitive tests in a group of older adult patients with MCI and OAB. PATIENT SUMMARY In this report, we investigated whether the medication fesoterodine, a member of a family of drugs called anticholinergics, commonly used for the treatment of a condition called overactive bladder that leads to accidental leakage of urine, affected the memory function of older adults with mild memory impairment. These people might be more sensitive to memory side effects. We found that at the doses most used by doctors, the drug had no effect on any of the memory functions we tested.

Abstract
INTRODUCTION Orphenadrine overdoses can cause antimuscarinic toxicity, respiratory failure, refractory seizures and cardiotoxicity. The dose-toxicity relationship is poorly defined. Orphenadrine is marketed as immediate and sustained release formulations, and it is not known how the formulation impacts on toxicity. We determined the clinical toxicity of orphenadrine in patients referred to a regional poisons centre. METHODS Retrospective case series of patients in New South Wales with orphenadrine deliberate self-poisoning from January 2016 to April 2022 referred to the New South Wales Poisons Information Centre. Demographics, history of exposure, treatment and outcomes were extracted from clinical databases. Receiver-operating characteristic curves were constructed to determine thresholds predicting toxicity. RESULTS Forty-eight patients were identified, with information on clinical outcomes in 46 patients and doses in 41 patients. All patients were older than 12 years. The median orphenadrine dose was 770 mg (range 210-10,000 mg), 59 per cent as the immediate release formulation, and 67 per cent reported coingestants. Doses of sustained release formulations were significantly greater than immediate release formulations, median 2,750 mg versus 595 mg. Common clinical features were drowsiness (59 per cent), sinus tachycardia (37 per cent) and confusion (33 per cent). Three patients had mild hypotension, three were intubated for coma, and two had seizures; no patients suffered ventricular dysrhythmias. All patients survived, with 75 per cent being medically cleared within 24 hours of presentation. A dose-toxicity relationship was observed, but conclusions are limited by the small number of cases with moderate or severe toxicity. DISCUSSION All patients survived, and severe cardiac and neurological toxicity were not observed. This contrasts to published case reports noting severe poisoning at similar or lower doses. Formulation may have an impact on outcomes, with lesser toxicity from sustained release products. CONCLUSIONS Orphenadrine doses up to 10 g were associated with antimuscarinic toxicity and sedation, but not severe cardiotoxicity. More research exploring the effect of dose and formulation on outcomes is required.

Abstract
IMPORTANCE There is strong evidence for long-term cognitive effects with anticholinergic use. Differences in insurance coverage of anticholinergics and beta-3 agonists hinder individualization of overactive bladder (OAB) treatment. OBJECTIVES The aims of the study were to assess individual and family health insurance plan coverage for select OAB medications and to compare coverage of preferred medications to those with a greater risk of cognitive dysfunction. STUDY DESIGN This cross-sectional study analyzed formularies for the top 7 U.S. medical insurers. Coverage tiers were assessed for the following 7 OAB medications: (1) oxybutynin instant-release 5 mg, (2) oxybutynin extended-release 5 mg, (3) solifenacin 5 mg, (4) trospium instant-release 20 mg, (5) trospium extended-release 60 mg, (6) mirabegron 25 mg, and (7) vibegron 75 mg. Coverage was compared between nonpreferred (oxybutynin, solifenacin) and preferred medications (trospium, mirabegron, vibegron). Coverage scores, representing a weighted average based on coverage tier frequency relative to the number of plans investigated for each state or insurer, were generated with a lower coverage score indicating better coverage (range, 0.2-1.0). RESULTS A total of 2,780 insurance plans from 41 states representing a 47% market share for the individual and family marketplace were evaluated. Oxybutynin IR had the best coverage score across insurers (0.2) while vibegron had the worst (0.92). Preferred medications were more often designated to higher tiers with worse coverage compared with nonpreferred medications (P < 0.001). Less concordance in coverage between insurers was noted for anticholinergics with greater bladder specificity and for extended-release formulations. CONCLUSIONS Despite risks with anticholinergics, beta-3 agonists were more expensive across all insurers highlighting the need for expanded coverage of preferred medications to avoid cognitive dysfunction when undergoing treatment for OAB.

Abstract
BACKGROUND Airway epithelial cells (AECs) are a major component of local airway immune responses. Direct effects of type 2 cytokines on AECs are implicated in type 2 asthma, which is driven by epithelial-derived cytokines and leads to airway obstruction. However, evidence suggests that restoring epithelial health may attenuate asthmatic features. METHODS We investigated the effects of passive sensitisation on IL-5, NF-κB, HDAC-2, ACh, and ChAT in human bronchial epithelial cells (HBEpCs) and the effects of fluticasone furoate (FF) and umeclidinium (UME) alone and in combination on these responses. RESULTS IL-5 and NF-κB levels were increased, and that of HDAC-2 reduced in sensitised HEBpCs. Pretreatment with FF reversed the effects of passive sensitisation by concentration-dependent reduction of IL-5, resulting in decreased NF-κB levels and restored HDAC-2 activity. Addition of UME enhanced these effects. Sensitized HEBpCs also exhibited higher ACh and ChAT levels. Pretreatment with UME significantly reduced ACh levels, and addition of FF caused a further small reduction. CONCLUSION This study confirmed that passive sensitisation of AECs results in an inflammatory response with increased levels of IL-5 and NF-κB, reduced levels of HDAC-2, and higher levels of ACh and ChAT compared to normal cells. Combining FF and UME was found to be more effective in reducing IL-5, NF-κB, and ACh and restoring HDAC-2 compared to the individual components. This finding supports adding a LAMA to established ICS/LABA treatment in asthma and suggests the possibility of using an ICS/LAMA combination when needed.

Abstract
OBJECTIVE Management of chronic obstructive pulmonary disease (COPD) with inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) improves lung function and health status and reduces COPD exacerbation risk versus monotherapy. This study described treatment use, healthcare resource utilisation (HCRU), healthcare costs and outcomes following initiation of single-device ICS/LABA as initial maintenance therapy (IMT). DESIGN Retrospective cohort study. SETTING Primary care, England. DATA SOURCES Linked data from the Clinical Practice Research Datalink Aurum and Hospital Episode Statistics datasets. PARTICIPANTS Patients with COPD and ≥1 single-device ICS/LABA prescription between July 2015 and December 2018 were included. PRIMARY AND SECONDARY OUTCOME MEASURES Treatment pathways, COPD-related HCRU and healthcare costs, COPD exacerbations, time to triple therapy, medication adherence (proportion of days covered ≥80%) and indexed treatment time to discontinuation. Data for patients without prior maintenance therapy history (IMT users) and non-triple users were assessed over a 12-month follow-up period. RESULTS Of 13 451 new ICS/LABA users, 5162 were IMT users (budesonide/formoterol, n=1056; beclomethasone dipropionate/formoterol, n=2427; other ICS/LABA, n=1679), for whom at 3 and 12 months post-index, 45.6% and 39.4% were still receiving any ICS/LABA. At >6 to ≤12 months, the proportion of IMT users with ≥1 outpatient visit (10.1%) and proportion with ≥1 inpatient stay (12.6%) had increased from those at 3 months (9.0% and 7.4%, respectively). Inpatient stays contributed most to total COPD-related healthcare costs. For non-triple IMT users, at 3 and 12 months post-index, 4.5% and 13.7% had ≥1 moderate-to-severe COPD exacerbation. Time to triple therapy initiation and time to discontinuation of index medication ranged from 45.9 to 50.2 months and 2.3 to 2.8 months between treatments. Adherence was low across all time points (21.5-27.6%). Results were similar across indexed therapies. CONCLUSIONS In the year following treatment initiation, ICS/LABA adherence was poor and many patients discontinued or switched therapies, suggesting that more consideration and optimisation of treatment is required in England for patients initiating single-device ICS/LABA therapy.

Abstract
The prevalence of myopia is increasing across the world. Controlling myopia progression would be beneficial to reduce adverse outcomes such as retinal detachment and myopic maculopathy which are associated with increased axial length. Pharmacological control of myopia progression with atropine has been investigated since the 19th century and the benefits of slowing myopia progression are considered against the side-effects of near blur and photophobia. More recently, randomised trials have focused on determining the optimum concentration of atropine leading to low-concentration atropine being used to manage myopia progression by practitioners across the world. Currently, in the United Kingdom, there is no licensed pharmacological intervention for myopia management. The aim of this review is to interpret the available data to inform clinical practice. We conducted a narrative review of the literature and identified peer-reviewed randomised controlled trials using the search terms 'myopia' and 'atropine', limited to the English language. We identified two key studies, which were the Atropine in the Treatment Of Myopia (ATOM) and Low-concentration Atropine for Myopia Progression (LAMP). Further studies were identified using the above search terms and the references from the identified literature. Atropine 0.01% has a modest effect on controlling axial length progression. Atropine 0.05% appears to be superior to atropine 0.01% in managing myopia progression. There is a dose-dependent rebound effect when treatment is stopped. Atropine is a well-tolerated, safe, and effective intervention. Treatment would be needed for several years and into adolescence, until axial length progression is stable.

Abstract
OBJECTIVES For patients with asthma who remain symptomatic on a medium-dose inhaled corticosteroid/long-acting β2 agonist, addition of a long-acting muscarinic antagonist as a supplementary controller is a recommended option. However, real-world data on the characteristics and treatment patterns of these patients are limited. This study described the demographics and clinical characteristics of new users of single- or multiple-inhaler triple therapy and treatment patterns preceding triple-therapy initiation. STUDY DESIGN This retrospective cohort study used medical and pharmacy claims data from the IQVIA PharMetrics Plus database. METHODS The study population comprised adults with asthma with or without chronic obstructive pulmonary disease (COPD) initiating triple therapy with single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI; 100/62.5/25 μg) or multiple-inhaler triple therapy (MITT) between September 18, 2017, and September 30, 2019. Demographics, clinical characteristics, and treatment patterns in the 12 months preceding triple-therapy initiation were described (baseline period). RESULTS A total of 12,395 patients were included. Among FF/UMEC/VI initiators with asthma (n = 1301), the mean age was 49.0 years and 59.3% were women. During the baseline period, 81.5% of patients used controller therapy, 94.7% used rescue medications, and 42.0% reported at least 1 asthma-related exacerbation; the annual mean exacerbation rate was 0.96. Similar trends were observed among patients with asthma initiating MITT and patients with comorbid asthma-COPD initiating FF/UMEC/VI or MITT. CONCLUSION In real-world practice, triple therapy is often utilized following other asthma controller medication use. High disease burden, as evidenced by substantial use of rescue medications and continued asthma-related exacerbations, suggests that patients may not have achieved adequate asthma control prior to triple-therapy initiation.

Abstract
BACKGROUND Cough is a common symptom in patients with chronic obstructive pulmonary disease (COPD). Patients with cough may exhibit various clinical characteristics and experience varying outcomes based on inhaled therapies they receive. OBJECTIVES This study aimed to explore the clinical characteristics and outcomes of various inhaled therapies in COPD patients with frequent cough. METHODS This was a multicenter, prospective cohort study. Of these patients, the median cough score in COPD assessment test (CAT) was two. Patients were classified into frequent cough group if they scored two or over in the first item of CAT and infrequent cough group otherwise. Patients with frequent cough were then divided into long-acting antimuscarinic (LAMA), long-acting beta2-agonist (LABA)/LAMA, inhaled corticosteroids (ICS)/LABA and ICS/LABA/LAMA groups. Minimum clinically important difference (MCID) (CAT scores decreased ≥2 from baseline) and the improvement of cough (cough score decreased ≥1 from baseline) were collected in the six-month follow-up. Frequent exacerbations (experiencing at least two exacerbations) were collected in the one-year follow-up. RESULTS Of 906 patients, 581 (64.1%) patients reported frequent cough at the initial visit. Frequent cough was associated with the current smokers and CAT scores (p < 0.05). The MCID showed no significant difference between frequent cough and infrequent cough groups in the follow-up. More patients with frequent cough experienced future frequent exacerbations compared to those with infrequent cough. After receiving inhaled therapies, 62% of patients with frequent cough got the cough improved. More patients with frequent cough treated with LABA/LAMA or ICS/LABA/LAMA attained MCID and fewer experienced exacerbations than those treated with LAMA or ICS/LABA (p < 0.05). The change in cough score showed no difference among various inhaled therapies in patients with frequent cough. CONCLUSION COPD patients with frequent cough were related to current smokers and higher CAT scores. These patients had a higher incidence of frequent exacerbations than those with infrequent cough. Patients with frequent cough who were treated with LABA/LAMA or ICS/LABA/LAMA were more likely to attain MCID and at a lower risk of exacerbation than those treated with LAMA or ICS/LABA.

Abstract
Sleep hyperhidrosis is defined as profuse nocturnal sweating that disrupts sleep. Although the mechanism is unknown, some cases are secondary to hot flushes during the menopausal period, medical, mental and sleep disorders, and medication, while dysregulation of thermoregulation during sleep is suspected in primary cases. We present the case of a woman with severe primary sleep hyperhidrosis, occurring nightly for 23 years, which definitively resolved after brief treatment with oxybutynin (a muscarinic receptor-blocking anticholinergic). An ammoniacal odor in the sweat and a sensation of coldness on awakening during sweating episodes suggest that the mechanism of her night sweating was not an exacerbation of thermoregulation during the night but shares the mechanical properties of emotional/psychological sweating. This extreme case of sleep hyperhidrosis was treated with excellent efficacy and minimal side effects using oxybutynin, which could benefit other patients with nighttime discomfort.

Abstract
MEDICATION MANAGEMENT OF COPD. The management of chronic obstructive pulmonary disease (COPD) is based on drug and non-drug measures. Inhaled therapies are the major issues including the use of short-acting bronchodilators for respiratory symptoms. If symptoms are daily, such as disabling dyspnea or frequent exacerbations, daily treatment with a long-acting bronchodilator is proposed: anti-muscarinic (LAMA) or β2-agonist (LABA). If there is no improvement, escalation to dual and then triple therapy is proposed. Another major issue in the management of COPD is de-escalation in the event of ineffectiveness or side effects of inhaled corticosteroids (ICS). Finally, the role of blood eosinophils and other biomarkers is even more important that biotherapies could expand the therapeutic options for some subtypes of COPD patients.

Abstract
OBJECTIVE To evaluate the evidence regarding the therapeutic benefits and safety of oral detrusor relaxing agents (DRAs) in treating neurogenic detrusor overactivity (NDO). METHODS A comprehensive search was performed on 1 September 2022. Two authors independently reviewed the articles to extract data using a pre-designed form. The meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A common-effect or random-effects model was used based on the heterogeneity among studies. Bayesian network meta-analysis (NMA) was further performed to make indirect comparisons of antimuscarinics and mirabegron. RESULTS A total of 23 randomised controlled trials (RCTs) comprising 1697 patients were included in our analysis. Compared to placebo, the clinical benefits of oral DRAs, along with more adverse events (AEs), were demonstrated in the treatment of NDO. In the subgroup analysis, antimuscarinics significantly improved both urodynamic and bladder diary outcomes (including urinary incontinence episodes, urinary frequency, and residual volume), with a higher rate of AEs, such as xerostomia. Mirabegron improved some of the parameters and had fewer bothersome side-effects in patients with NDO. The NMA showed that none of the antimuscarinics or mirabegron was superior or inferior to the other. CONCLUSIONS Detrusor relaxing agents are associated with improved outcomes in patients with NDO and our analysis has added new evidence regarding antimuscarinics. Evidence concerning mirabegron as first-line therapy for NDO is still limited. Well-designed RCTs are still required in this specific population.

Abstract
Rationale: Obstructive sleep apnea (OSA) is a common sleep disorder for which the principal treatment option, continuous positive airway pressure, is often poorly tolerated. There is currently no approved pharmacotherapy for OSA. However, recent studies have demonstrated improvement in OSA with combined antimuscarinic and noradrenergic drugs. Objectives: The aim of this study was to evaluate the efficacy and safety of AD109, a combination of the novel antimuscarinic agent aroxybutynin and the norepinephrine reuptake inhibitor atomoxetine, in the treatment of OSA. Methods: Phase II randomized, double-blind, placebo-controlled, parallel-group, 4-week trial comparing AD109 2.5/75 mg, AD109 5/75 mg, atomoxetine 75 mg alone, and placebo (www.clinicaltrials.gov identifier NCT05071612). Measurements and Main Results: Of 211 randomized patients, 181 were included in the prespecified efficacy analyses. Sleep was assessed by two baseline and two treatment polysomnograms. Apnea-hypopnea index with a 4% desaturation criterion (primary outcome) was reduced from a median (IQR) of 20.5 (12.3-27.2) to 10.8 (5.6-18.5) in the AD109 2.5/75 mg arm (-47.1%), from 19.4 (13.7-26.4) to 9.5 (6.1-19.3) in the AD109 5/75 mg arm (-42.9%; both P < 0.0001 vs. placebo), and from 19.0 (11.8-28.8) to 11.8 (5.5-21.5) with atomoxetine alone (-38.8%; P < 0.01 vs. placebo). Apnea-hypopnea index with a 4% desaturation criterion decreased from 20.1 (11.9-25.9) to 16.3 (11.1-28.9) in the placebo arm. Subjectively, there was improvement in fatigue with AD109 2.5/75 mg (P < 0.05 vs. placebo and atomoxetine). Atomoxetine taken alone decreased total sleep time (P < 0.05 vs. AD109 and placebo). The most common adverse events were dry mouth, insomnia, and urinary hesitancy. Conclusions: AD109 showed clinically meaningful improvement in OSA, suggesting that further development of the compound is warranted. Clinical trial registered with www.clinicaltrials.gov (NCT05071612).

Abstract
WHAT IS THIS SUMMARY ABOUT? Inhaled corticosteroids (ICS) are a type of medication delivered via an inhaler device that are commonly used in the treatment of asthma. ICS can also be used to treat chronic obstructive pulmonary disease (COPD), a progressive respiratory condition in which the lungs become worse over time. However, unlike in asthma, ICS are only effective in a small proportion of people with COPD. ICS can cause significant side effects in people with COPD, including pneumonia. Because of this, guidelines written by COPD experts recommend that ICS should largely be prescribed to people with COPD whose symptoms flare up frequently and become difficult to manage (episodes known as exacerbations). Despite this guidance, records collected from routine clinical practice suggest that many healthcare professionals prescribe ICS to people with COPD who do not have frequent exacerbations, putting them at unnecessary risk of side effects. The over-prescription of ICS in COPD may partly be due to the recent introduction of single-inhaler combination therapies, which combine ICS with other medicines (bronchodilators). This 'one inhaler for all' approach is a concerning trend as it goes against global COPD treatment guidelines, which recommend ICS use in only a small proportion of people. This is a plain language summary of a review article originally published in the journal NPJ Primary Care Respiratory Medicine. In this review, we investigate the benefits and risks of ICS use in COPD. Using data from both randomized controlled trials (RCTs) and observational studies, we explain which people benefit from ICS use, and why health regulatory bodies have concluded that ICS do not help people with COPD to live longer. Lastly, we provide practical guidance for doctors and people with COPD regarding when ICS should be prescribed and when they should be withdrawn. VIDEO ABSTRACT

Abstract
INTRODUCTION Neurogenic lower urinary tract dysfunction (NLUTD) in children can cause renal failure and urinary incontinence if not treated sufficiently. Antimuscarinics (AM) and intradetrusor botulinum toxin injections (BoNT-A) with clean intermittent catheterization (CIC) are widely used treatment options for children with NLUTD. However, a considerable number will become refractory to these treatment options. This study aimed to evaluate the efficacy and long-term outcomes of mirabegron in children with NLUTD as an add-on and as a stand-alone treatment. MATERIAL AND METHODS Patients under 18 years of age with NLUTD who were refractory to AM and/or BoNT-A and were treated with mirabegron 50 mg were retrospectively studied. Mirabegron was either used as monotherapy or in addition to AM and/or BoNT-A. Video-urodynamic studies (VUDSs) were performed before and after treatment with mirabegron. Changes in video-urodynamic parameters, the need for other NLUTD therapy during follow-up, patient-reported side effects, and urinary incontinence were outcomes of interest. RESULTS A total of 34 patients with NLUTD were included. All patients were on CIC and the median age was 13.1 years (IQR 15.9-10.3). Median follow-up was 31.4 months (IQR 57.4-11.4). Bladder compliance improved by 89.9%, from 14.9 to 28.3 ml/cm H2O (p-value<0.001). Maximum cystometric capacity, end-filling detrusor pressure, volume at first detrusor overactivity, vesicoureteral reflux, and urinary incontinence significantly improved after mirabegron. The add-on therapy group showed more significant improvements in video-urodynamic outcomes compared to the monotherapy group. The median time of requiring other NLUTD therapy was 25.5 months (IQR 39.8-14.8). None of the included patients reported side effects. CONCLUSIONS Mirabegron is an effective treatment for children with therapy-refractory NLUTD with an average efficacy of 2 years after which additional therapy is required. Despite the retrospective character of this study, our results confirm the beneficial effect of mirabegron in children with therapy-refractory NLUTD, in particular when mirabegron is used as add-on therapy in those with low-compliance bladders.

Abstract
Background: Based on current clinical guidelines, long-acting β2-agonists (LABA) are frequently prescribed before long-acting muscarinic antagonists (LAMA) as an add-on to inhaled corticosteroids (ICS) in uncontrolled asthma. However, there is insufficient real-world evidence that supports this therapeutic approach. Objective: The objective was to compare asthma exacerbations and healthcare resource utilization in patients with asthma using the LAMA tiotropium bromide (Tio) or a LABA as an add-on to ICS (ICS + Tio or ICS/LABA) in a real-world setting. Methods: This retrospective, observational study included patients aged ≥12 years with asthma diagnoses identified in a U.S. longitudinal claims database (October 2015 to August 2020). The ICS + Tio and ICS/LABA cohorts were 1:2 propensity score matched for baseline variables. Outcomes were compared in the postmatched cohorts, and the risk of exacerbation was evaluated by using Kaplan-Meier curves. Results: After propensity score matching, there were 633 and 1266 patients in the ICS + Tio and ICS/LABA cohorts, respectively. The proportion of patients who experienced a severe or a moderate-or-severe exacerbation during follow-up was similar between the ICS + Tio versus ICS/LABA cohorts (4% versus 3%, p = 0.472, and 50% versus 45%, p = 0.050, respectively). The mean time to first severe (ICS + Tio 43.8 days versus ICS/LABA 49.4 days, p = 0.758) and moderate-or-severe exacerbation (ICS + Tio 65.8 days versus ICS/LABA 58.9 days, p = 0.474) was not statistically different between cohorts. The treatments had no effect on the risk of severe exacerbation, although it was 36% lower in ICS + Tio users than in ICS/LABA users (hazard ratio 0.64 [95% confidence interval, 0.22-1.84]). All-cause and asthma-related average monthly healthcare resource utilization were comparable between the treatments for hospitalizations and emergency department visits but were significantly greater in the ICS + Tio cohort than in the ICS/LABA cohort for asthma-related outpatient visits (p < 0.0001). Conclusion: This study provides real-world evidence that ICS + Tio may be a valid alternative when ICS/LABA cannot be used as first-line treatment for asthma maintenance therapy.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality globally. In the major revision of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 report, the scientific committee concluded that the use of long-acting β2-agonist/inhaled corticosteroids (LABA/ICS) is not encouraged in patients with COPD. However, current prescribing patterns reveal significant use of LABA/ICS. In this paper, the evidence behind the current practice and the latest treatment recommendations is reviewed. We compare the efficacy and safety of combination therapy with long-acting muscarinic antagonist (LAMA) and LABA vs LABA/ICS and note that LAMA/LABA combinations have reduced the annual rate of moderate/severe exacerbations, delayed the time to first exacerbation, and increased post-dose FEV1 vs ICS-based regimens. The GOLD 2023 report recommends treatment with LABA and LAMA combination (preferably as a single inhaler) in patients with persistent dyspnea, with initiation of ICS in patients based on the symptoms (dyspnea and exercise intolerance as indicated by modified Medical Research Council [mMRC] score ≥ 2 and COPD Assessment Test [CAT™] > 20), blood eosinophil count (≥ 300 cells/µL), and exacerbation history (history of hospitalizations for exacerbations of COPD and ≥ 2 moderate exacerbations per year despite appropriate long-acting bronchodilator maintenance therapy). We describe practical recommendations for primary care physicians to optimize therapy for their patients and prevent overuse of ICS-based regimens. We advocate adherence to current recommendations and a greater focus on effective treatments to successfully control symptoms, minimize exacerbation risk, preserve lung function, maximize patient outcomes, and reduce the burden of drug-related adverse events.

Abstract
AVANT was a Phase 3, 24-week, randomized, parallel-group, double-blind, double-dummy, placebo-controlled study to assess the efficacy and safety of aclidinium/formoterol 400 μg/12 μg combination vs monotherapies and aclidinium vs placebo (1:1:1:1) in Asian patients (∼70% of whom were Chinese) with moderate-to-severe stable chronic obstructive pulmonary disease. Endpoints were analyzed hierarchically to incorporate type I error control. At Week 24, aclidinium/formoterol demonstrated improvements from baseline in 1-h morning post-dose forced expiratory volume in 1 s (FEV1) vs aclidinium (least squares [LS] mean 92 mL; 95% confidence interval [CI] 60, 124 mL; p < 0.001), and in trough FEV1 vs formoterol (LS mean 85 mL; 95% CI 53, 117 mL; p < 0.001). Furthermore, aclidinium provided improvements in trough FEV1 vs placebo (LS mean 134 mL; 95% CI 103, 166 mL; p < 0.001). There was an improvement in transition dyspnea index focal score at Week 24 for aclidinium/formoterol vs placebo (LS mean 0.8; 95% CI 0.2, 1.3; p = 0.005) but not for aclidinium vs placebo (LS mean 0.4; 95% CI -0.1, 1.0; p = 0.132). Improvements in St George's Respiratory Questionnaire total scores occurred for aclidinium/formoterol vs placebo (LS mean -4.0; 95% CI -6.7, -1.4; p = 0.003) and aclidinium vs placebo (LS mean -2.9; 95% CI -5.5, -0.3; p = 0.031). Aclidinium/formoterol and aclidinium were well tolerated and safety findings were consistent with known profiles; rates of treatment-emergent adverse events (AEs) (aclidinium/formoterol: 54.8%; aclidinium: 47.4%; placebo: 53.9%), serious AEs (7.2, 7.9, and 7.8%, respectively), and AEs leading to discontinuation of study medication (2.3, 1.5, and 2.2%, respectively) were similar between groups.

Abstract
Chronic obstructive pulmonary disease patient care must include confirming a diagnosis with postbronchodilator spirometry. Because of the clinical heterogeneity and the reality that airflow obstruction assessed by spirometry only partially reflects disease severity, a thorough clinical evaluation of the patient should include assessment of symptom burden and risk of exacerbations that permits the implementation of evidence-informed pharmacologic and nonpharmacologic interventions. This guideline provides recommendations from a comprehensive systematic review with a meta-analysis and expert-informed clinical remarks to optimize maintenance pharmacologic therapy for individuals with stable COPD, and a revised and practical treatment pathway based on new evidence since the 2019 update of the Canadian Thoracic Society (CTS) Guideline. The key clinical questions were developed using the Patients/Population (P), Intervention(s) (I), Comparison/Comparator (C), and Outcome (O) model for three questions that focuses on the outcomes of symptoms (dyspnea)/health status, acute exacerbations, and mortality. The evidence from this systematic review and meta-analysis leads to the recommendation that all symptomatic patients with spirometry-confirmed COPD should receive long-acting bronchodilator maintenance therapy. Those with moderate to severe dyspnea (modified Medical Research Council ≥ 2) and/or impaired health status (COPD Assessment Test ≥ 10) and a low risk of exacerbations should receive combination therapy with a long-acting muscarinic antagonist/long-acting ẞ2-agonist (LAMA/LABA). For those with a moderate/severe dyspnea and/or impaired health status and a high risk of exacerbations should be prescribed triple combination therapy (LAMA/LABA/inhaled corticosteroids) azithromycin, roflumilast or N-acetylcysteine is recommended for specific populations; a recommendation against the use of theophylline, maintenance systemic oral corticosteroids such as prednisone and inhaled corticosteroid monotherapy is made for all COPD patients.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction on spirometry and symptoms such as dyspnea on exertion and chronic cough with sputum production, thus making it a significant healthcare issue worldwide. Japanese patients with COPD have unique characteristics compared to patients in Western countries, including older age and lower exacerbation frequency. The Japanese Respiratory Society (JRS) published the 6th edition of the COPD guideline in June 2022. This article introduces the management goals of COPD and describes its management during the stable phase, as outlined in the guideline. Management goals include improving the current status, such as the symptoms, quality of life (QOL), exercise tolerance, and physical activity, and reducing future risks through prevention of exacerbation and suppression of disease progression to prevent shortening of healthy life expectancy. Management plans should include avoidance of causative substances, assessment of disease severity, and personalized treatment plans. Pharmacotherapy using inhalation bronchodilators is a key component of the treatment of stable COPD. Bronchodilators, including short- and long-acting dilators, are commonly used to relieve symptoms and improve QOL. Inhaled corticosteroids (ICSs) are used in combination with long-acting bronchodilators, especially in patients with asthma and COPD overlap, or those experiencing frequent exacerbation of eosinophilia. Combination therapy with a long-acting muscarinic antagonist (LAMA), a long-acting beta 2 agonist (LABA), and ICS is expected to improve QOL and respiratory function and reduce mortality and exacerbation compared to the LAMA + LABA combination. Non-pharmacological therapies, including smoking cessation and pulmonary rehabilitation, should also be considered.

Abstract
BACKGROUND Patients with benign prostatic hyperplasia (BPH) receive α-blockers as first-line therapy to treat lower urinary tract symptoms; however, some individuals still experience residual storage symptoms. Antimuscarinics, β3-agonists, and desmopressin are effective add-on medications. Nevertheless, there is currently no evidence for the appropriate choice of the first add-on medication. This systematic review aimed to investigate the clinical benefits of antimuscarinics, β3-agonists, and desmopressin, in addition to α-blockers, for persistent storage symptoms in BPH patients. METHODS A comprehensive literature search of randomized controlled trials (RCTs) comparing the efficacy of different add-on medications in BPH patients with persistent storage symptoms despite α-blocker treatment was conducted. Clinical outcomes included the International Prostate Symptom Score (IPSS), IPSS storage subscore, nocturia, micturition, and urgency. A network meta-analysis was performed to estimate the effect size. Surface under cumulative ranking curves (SUCRAs) were used to rank the included treatments for each outcome. RESULTS A total of 15 RCTs were identified. Add-on imidafenacin and mirabegron resulted in significant improvement in all outcomes assessed. Other add-on medications such as desmopressin, tolterodine, solifenacin, fesoterodine, and propiverine showed positive benefits for most, but not all, outcomes. Based on the SUCRA rankings, add-on desmopressin was the best-ranked treatment for IPSS and nocturia, and add-on imidafenacin was the best for the IPSS storage subscore and micturition. CONCLUSIONS BPH patients presenting with persistent storage symptoms despite α-blocker administration are recommended to include additional treatment. Desmopressin and imidafenacin may be considered high-priority add-on treatments because of their superior efficacy compared with other medications.
