Predictors of non-persistence in women with overactive bladder syndrome.

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.

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 Comparison of U.S. Individual and Family Plan Medication Coverage for Overactive Bladder.

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.

Real-World Effectiveness of Single-Inhaler Triple Therapy for COPD: Impact of Diabetes Comorbidity.

Type 2 diabetes is a frequent comorbidity in chronic obstructive pulmonary disease (COPD) patients, with the GOLD treatment recommendations asserting that the presence of diabetes be disregarded in the choice of treatment.In a cohort of COPD patients with frequent exacerbations, initiators of single-inhaler triple therapy or dual bronchodilators were compared on the incidence of COPD exacerbation and pneumonia over one year, adjusted by propensity score weighting and stratified by type 2 diabetes.The COPD cohort included 1,114 initiators of triple inhalers and 4,233 of dual bronchodilators (28% with type 2 diabetes). The adjusted hazard ratio (HR) of exacerbation with triple therapy was 1.04 (95% CI: 0.86-1.25) among COPD patients with type 2 diabetes and 0.74 (0.65-0.85) in those without. The incidence of severe pneumonia was elevated with triple therapy among patients with type 2 diabetes (HR 1.77; 1.14-2.75).Triple therapy in COPD is effective among those without, but not those with, type 2 diabetes. Future therapeutic trials in COPD should consider diabetes comorbidity.

Triple therapy for frequent COPD exacerbators is effective in patients without type 2 diabetes but not in those with type 2 diabetes. The impact of comorbidities should be considered in future COPD therapeutic trials.

An eco-friendly one-pot spectrofluorimetric approach for the facile determination of overactive bladder drug, tolterodine: Application to dosage forms and biological fluids.

Tolterodine tartrate (TTD) was the first antimuscarinic medication developed exclusively for the treatment of overactive bladder syndrome and was approved by the FDA in 1998. As a result of the drug's extensive utilization within the local community following its authorization, there is a pressing need to develop and validate a spectrofluorometric method that is economically efficient, easily reproducible, environmentally sustainable, and possesses high sensitivity. The developed approach relies on enhancing the fluorescence intensity of TTD to reach a level 720 % higher than its initial value, achieved through the application of an aqueous sodium dodecyl sulfate (SDS) solution. A strong correlation was observed with a correlation coefficient of 0.9998 between the concentration of TTD and the fluorescence intensity within the range of 25.0-500.0 ng mL-1. This approach could be employed to quantify TTD in its pure form and to examine pharmaceutical tablets for the purposes of verifying uniform content. Additionally, it was utilized for the evaluation of TTD concentrations in spiked human plasma.

Multidisciplinary Management of Patients With Chronic Obstructive Pulmonary Disease and Cardiovascular Disease.

Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) frequently coexist, increasing the prevalence of both entities and impacting on symptoms and prognosis. CVD should be suspected in patients with COPD who have high/very high risk scores on validated scales, frequent exacerbations, precordial pain, disproportionate dyspnea, or palpitations. They should be referred to cardiology if they have palpitations of unknown cause or angina pain. COPD should be suspected in patients with CVD if they have recurrent bronchitis, cough and expectoration, or disproportionate dyspnea. They should be referred to a pulmonologist if they have rhonchi or wheezing, air trapping, emphysema, or signs of chronic bronchitis. Treatment of COPD in cardiovascular patients should include long-acting muscarinic receptor antagonists (LAMA) or long-acting beta-agonists (LABA) in low-risk or high-risk non-exacerbators, and LAMA/LABA/inhaled corticosteroids in exacerbators who are not controlled with bronchodilators. Cardioselective beta-blockers should be favored in patients with CVD, the long-term need for amiodarone should be assessed, and antiplatelet drugs should be maintained if indicated.

Preliminary investigation of the administration of biperiden to reduce relapses in individuals with cocaine/crack user disorder: A randomized controlled clinical trial.

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.

Cardiovascular Events with the Use of Long-Acting Muscarinic Receptor Antagonists: An Analysis of the FAERS Database 2020-2023.

PURPOSE: This study aimed to examine reports of cardiovascular adverse events (CV AEs) observed in the real-world during treatment with aclidinium, tiotropium, glycopyrronium, and umeclidinium alone or in combination with a LABA and, in the context of triple therapy, with the addition of an ICS, and submitted to the food and drug administration adverse event reporting system (FAERS). METHODS: A retrospective disproportionality analysis was conducted utilizing CV AE reports submitted to the FAERS from January 2020 to 30 September 2023. Disproportionality was measured by calculating the reporting odds ratio. RESULTS: Compared with ipratropium, tiotropium was associated with fewer reports of CV AEs. Compared with tiotropium, other LAMAs were more likely to be associated with reports of CV AEs. Combinations of glycopyrronium with indacaterol or formoterol and umeclidinium with vilanterol significantly reduced reports of CV AEs compared with the respective LAMA. The addition of an ICS to these combinations further reduced the risk of CV AE reports. CONCLUSION: Our study suggests that inhaled LAMAs are not free from cardiac AE risks. This risk may be more evident when the newer LAMAs are used, but it is generally significantly reduced when COPD patients are treated with dual bronchodilators or triple therapy. However, these results do not prove that LAMAs cause CV AEs, as FAERS data alone are not indicative of a drug's safety profile. Given the frequency with which COPD and cardiovascular disease co-exist, a large study in the general population could shed light on this very important issue.

Treatment pathways, economic burden and clinical outcomes in new users of inhaled corticosteroid/long-acting B2-agonist dual therapy with chronic obstructive pulmonary disease in a primary care setting in England: a retrospective cohort study.

OBJECTIVE: Management of chronic obstructive pulmonary disease (COPD) with inhaled corticosteroid/long-acting ß2-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.

[Medication management of COPD]. / Prise en charge médicamenteuse de la BPCO.

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 ß2-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.

PRISE EN CHARGE MÉDICAMENTEUSE DE LA BPCO. La prise en charge de la bronchopneumopathie chronique obstructive (BPCO) repose sur des mesures médicamenteuses et non médicamenteuses. Le principe des traitements médicamenteux dans la BPCO comprend des traitements inhalés, et notamment l'utilisation de bronchodilatateurs de courte durée d'action en cas de symptômes respiratoires. Si les symptômes sont quotidiens à type de dyspnée invalidante ou en cas d'exacerbations fréquentes, un traitement de fond quotidien par un bronchodilatateur de longue durée d'action est indiqué : antimuscarinique (LAMA) ou ß2-agoniste (LABA). En l'absence d'amélioration, une escalade est proposée par bithérapie puis trithérapie. Un autre enjeu majeur de la prise en charge de la BPCO est la désescalade thérapeutique en cas d'inefficacité ou d'effets indésirables des corticostéroïdes inhalés (CSI). Enfin, la place du dosage des éosinophiles et autres biomarqueurs sanguins est d'autant plus importante que les biothérapies pourraient venir élargir l'arsenal thérapeutique pour certains soustypes de patients atteints de BPCO.

The effect of combining an inhaled corticosteroid and a long-acting muscarinic antagonist on human airway epithelial cells in vitro.

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.

Real-world users of triple therapy for asthma in the US.

OBJECTIVES: For patients with asthma who remain symptomatic on a medium-dose inhaled corticosteroid/long-acting ß2 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.

Severe night sweating treated by oxybutynin.

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.

Detrusor relaxing agents for neurogenic detrusor overactivity: a systematic review, meta-analysis and network meta-analysis.

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.

[Perioperative Rehabolotation Usefulness in Preventing Complications].

The number of elderly patients in thoracic surgery is increasing. The percentage of patients over the age of 80 in surgical cases of malignant diseases such as lung cancer and mediastinal tumors is increasing every year. It is also true that the indications for surgery have been expanding as surgery itself has become less invasive, such as thoracoscopic and robotic surgery. However, it is not uncommon for patients over 80 years of age to have some organ dysfunction and many comorbidities. Therefore, when performing surgery for lung cancer and other diseases, it is important to assess the patient's ability to tolerate surgery, including respiratory and cardiac functions, and to perform risk management. To prevent postoperative complications and improve the accuracy of perioperative management, respiratory rehabilitation should be conducted before and after surgery, and not only smoking cessation instruction but also inhalation training using incentive spirometry( IS), breathing exercises, and the use of inhalers such as long-acting ß2 agonist (LABA)/long-acting muscaring antagonist (LAMA) for patients with chronic obstructive pulmonary disease( COPD) are useful.

[CQ IN THE LONG-TERM MANAGEMENT OF ADULT ASTHMATIC PATIENTS WHO ARE NOT ADEQUATELY CONTROLLED WITH INHALED CORTICOSTEROIDS MONOTHERAPY, WHICH IS MORE BENEFICIAL: ADDING A LONG ACTING BETA2 AGONIST OR A LONG ACTING MUSCARINIC ANTAGONIST?]

Long-acting beta2-agonists (LABA) are preferred add-on treatment for adult asthmatic patients whose symptoms cannot be controlled with inhaled corticosteroids (ICS) alone. However, over the last decade, long-acting muscarinic antagonists (LAMA) have gained approval for use in treating asthma, and their efficacy is anticipated. Therefore, we conducted a systematic review to investigate whether the addition of LABA or LAMA is more beneficial for the long-term management of adult asthmatic patients poorly controlled on ICS monotherapy. We extracted eight relevant randomized controlled trials (represented in 18 articles) conducted by June 2022 form the corresponding Cochrane review and additional searches through medical databases (CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and ICHUSHI (https://www.jamas.or.jp/)). While the LAMA add-on group showed a significantly better improvement in some respiratory function tests, the difference between groups did not exceed the minimum clinically important difference (MCID). On the other hand, the Asthma Quality of Life Questionnaire, a quality of life metric, was significantly higher in the LABA add-on group, but the difference also did not surpass the MCID. Because no outcomes exceeded the MCID, we could not determine whether adding LABA or LAMA on ICS is more beneficial in the long-term management of adult asthmatic patients. Given that no significant differences were found in the incidence of adverse events (including serious ones), when specific adverse events associated with one treatment occur, switching to the other treatment (from LABA to LAMA, or vice versa) can be considered as an option.

Overuse of long-acting ß2-agonist/inhaled corticosteroids in patients with chronic obstructive pulmonary disease: time to rethink prescribing patterns.

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 ß2-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.

Chronic obstructive pulmonary disease (COPD) is a common disease of the lungs associated with continued respiratory symptoms and airflow limitation. COPD causes symptoms such as breathlessness, cough, and production of phlegm, and, if not properly managed, these symptoms may get worse and result in flare-ups, also termed exacerbations. COPD management includes controlling symptoms while reducing the risk of exacerbations. COPD treatments include bronchodilators and inhaled corticosteroids (ICS). Bronchodilators help by widening the airways, making it easier to breathe. The two types of bronchodilators are long-acting muscarinic antagonists (LAMAs; these drugs prevent closing of the airways) and long-acting ß₂-agonists (LABAs; these drugs relax the muscles around the airways to help keep the airways open for a longer time). ICS may reduce swelling in the airways in some patients with COPD. However, the use of ICS-based regimens as the first treatment choice has been linked to health risks and is not in keeping with the recent national and international recommendations. In this narrative review, we examine why the use of ICS-based regimens is still growing and explore, based on available evidence, and why this treatment course may not be optimal for most patients with COPD. We discuss how the treatment for COPD has changed over time, and our findings support the use of LAMA and LABA as the first course of therapy in many patients with COPD. We conclude that greater adherence to the treatment guidelines can help to improve treatment outcomes for many patients with COPD.

Rational use of inhaled corticosteroids for the treatment of COPD: a plain language summary.

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.
