Single-Inhaler Fluticasone Furoate/Umeclidinium/Vilanterol Bremner et al. Respiratory Research (2018) 19:19 DOI 10.1186/s12931-018-0724-0 RESEARCH Open Access Single-inhaler fluticasone furoate/ umeclidinium/vilanterol versus fluticasone furoate/vilanterol plus umeclidinium using two inhalers for chronic obstructive pulmonary disease: a randomized non- inferiority study Peter R. Bremner1, Ruby Birk2, Noushin Brealey2, Afisi S. Ismaila3,4, Chang-Qing Zhu2 and David A. Lipson5,6* Abstract Background: Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 μg has been shown to improve lung function and health status, and reduce exacerbations, versus budesonide/formoterol in patients with chronic obstructive pulmonary disease (COPD). We evaluated the non-inferiority of single-inhaler FF/ UMEC/VI versus FF/VI + UMEC using two inhalers. Methods: Eligible patients with COPD (aged ≥40 years; ≥1 moderate/severe exacerbation in the 12 months before screening) were randomized (1:1; stratified by the number of long-acting bronchodilators [0, 1 or 2] per day during run-in) to receive 24-week FF/UMEC/VI 100/62.5/25 μg and placebo or FF/VI 100/25 μg + UMEC 62.5 μg; all treatments/placebo were delivered using the ELLIPTA inhaler once-daily in the morning. Primary endpoint: change from baseline in trough forced expiratory volume in 1 s (FEV1) at Week 24. The non-inferiority margin for the lower 95% confidence limit was set at − 50 mL. Results: A total of 1055 patients (844 [80%] of whom were enrolled on combination maintenance therapy) were randomized to receive FF/UMEC/VI (n = 527) or FF/VI + UMEC (n = 528). Mean change from baseline in trough FEV1 at Week 24 was 113 mL (95% CI 91, 135) for FF/UMEC/VI and 95 mL (95% CI 72, 117) for FF/VI + UMEC; the between-treatment difference of 18 mL (95% CI -13, 50) confirmed FF/UMEC/VI’s was considered non-inferior to FF/ VI + UMEC. At Week 24, the proportion of responders based on St George’s Respiratory Questionnaire Total score was 50% (FF/UMEC/VI) and 51% (FF/VI + UMEC); the proportion of responders based on the Transitional Dyspnea Index focal score was similar (56% both groups). A similar proportion of patients experienced a moderate/severe exacerbation in the FF/UMEC/VI (24%) and FF/VI + UMEC (27%) groups; the hazard ratio for time to first moderate/ severe exacerbation with FF/UMEC/VI versus FF/VI + UMEC was 0.87 (95% CI 0.68, 1.12). The incidence of adverse events was comparable in both groups (48%); the incidence of serious adverse events was 10% (FF/UMEC/VI) and 11% (FF/VI + UMEC).

Abstract Indacaterol is a novel β2-adrenoceptor agonist in development for the once-daily treatment of asthma and COPD. This study evaluated the relaxant effect of indacaterol on isolated human bronchi obtained from lungs of patients undergoing surgery for lung carcinoma. Potency (-logEC50), intrinsic efficacy (Emax) and onset of action were determined at resting tone. Duration of action was determined against cholinergic neural contraction induced by electrical field stimulation (EFS). At resting tone, -logEC50 and Emax values were, respectively, 8.82±0.41 and 77±5% for indacaterol, 9.84±0.22 and 94±1% for formoterol, 8.36±0.16 and 74±4% for salmeterol, and 8.43±0.22 and 84±4% for salbutamol. In contrast to salmeterol, indacaterol did not antagonize the isoprenaline response.

  • Effect of Theophylline and Enprofylline on Bronchial Hyperresponsiveness
    Thorax: first published as 10.1136/thx.44.12.1022 on 1 December 1989. Downloaded from Thorax 1989;44:1022-1026 Effect of theophylline and enprofylline on bronchial hyperresponsiveness G H KOETER, J KRAAN, M BOORSMA, J H G JONKMAN, TH W VAN DER MARK From the Department ofPulmonology and Lung Function, University Hospital, Groningen; Pharma Bio Research, Assen; and Astra Pharmaceutica, Rijswijk, The Netherlands ABSTRACT The effect of increasing intravenous doses of theophylline and enprofylline, a new xanthine derivative, on bronchial responsiveness to methacholine was studied in eight asthmatic patients. Methacholine provocations were carried out on three days before and after increasing doses of theophylline, enprofylline, and placebo, a double blind study design being used. Methacholine responsiveness was determined as the provocative concentration of methacholine causing a fall of 20% in FEV, (PC20). The patients were characterised pharmacokinetically before the main study to provide an individual dosage scheme for each patient that would provide rapid steady state plasma concentration plateaus of 5, 10, and 15 mg/l for theophylline and 1 25, 2 5, and 3-75 mg/l for enprofylline. Dose increments in the main study were given at 90 minute intervals. FEV, showed a small progressive decrease after placebo; it remained high in relation to placebo after both drugs and this effect was dose related. Methacholine PC20 values decreased after placebo; mean values were (maximum difference 2-0 and 1 7 higher after theophylline and enprofylline than after placebo copyright. doubling doses of methacholine); the effect of both drugs was dose related. Thus enprofylline and theophylline when given intravenously cause a small dose related increase in FEV1 and methacholine PC20 when compared with placebo.

  • Beclometasone / Formoterol / Glycopyrronium Bromide Pressurised Metered Dose Inhaler (Trimbow®) for the Treatment of COPD
    Beclometasone / formoterol / glycopyrronium bromide pressurised metered dose inhaler (Trimbow®) for the treatment of COPD Commissioning Statement Fylde and Wyre Clinical Commissioning Group has agreed to fund the prescribing of Beclometasone / formoterol / glycopyrronium bromide pressurised metered dose inhaler (Trimbow®) for the treatment of COPD Restriction: Triple therapy should be reserved for patients who have failed to achieve or maintain an adequate response to an appropriate course of dual therapy This medicine is classified as GREEN (Restricted) for this indication Summary of supporting evidence TRILOGY shows that in patients with COPD who have severe or very severe airflow limitation,symptoms, and an exacerbation history, triple therapy with BDP/FF/GB (beclomethasone dipropionate / formoterol fumarate / glycopyrronium bromide) had a greater effect on pre-dose and 2-h post-dose FEV1 than BDP/FF. For the co-primary endpoint measuring breathlessness (Transition Dyspnea Index, TDI), superiority of BDP/FF/GB over BDP/FF was not shown. The rate of moderate-to-severe COPD exacerbations was 23% lower with BDP/FF/GB compared with BDP/FF, with the time to first exacerbation significantly longer with triple therapy. Thus, the greater improvement in lung function with BDP/FF/GB compared with BDP/FF was more clearly accompanied by a reduction in exacerbations than an improvement in breathlessness in this group of patients. Furthermore, BDP/FF/GB had a greater effect on health related quality of life than BDP/FF. TRINITY met the primary and both key secondary endpoints. Extrafine fixed triple (i.e. extra fine inhaled particle fraction, ICS/LABA/LAMA in one inhaler) resulted in a 20% (95% CI 8– 31) reduction in the rate of moderate-to-severe COPD exacerbations compared with tiotropium, together with a 0·061L mean improvement in pre-dose FEV1.

These authors contributed equally. y Co-last authors. z Received: 22 July 2020; Accepted: 4 September 2020; Published: 8 September 2020 Abstract: The senescence process is the result of a series of factors that start from the genetic constitution interacting with epigenetic modifications induced by endogenous and environmental causes and that lead to a progressive deterioration at the cellular and functional levels. One of the main causes of aging is oxidative stress deriving from the imbalance between the production of reactive oxygen (ROS) and nitrogen (RNS) species and their scavenging through antioxidants. Xanthine oxidoreductase (XOR) activities produce uric acid, as well as reactive oxygen and nitrogen species, which all may be relevant to such equilibrium. This review analyzes XOR activity through in vitro experiments, animal studies and clinical reports, which highlight the pro-aging effects of XOR products. However, XOR activity contributes to a regular level of ROS and RNS, which appears essential for the proper functioning of many physiological pathways. This discourages the use of therapies with XOR inhibitors, unless symptomatic hyperuricemia is present.

  • Hypersalivation in Children and Adults
    Pharmacological Management of Hypersalivation in Children and Adults Scope: Adult patients with Parkinson’s disease, children with neurodisability, cerebral palsy, long-term ventilation with drooling, and drug-induced hypersalivation. ASSESSMENT OF SEVERITY/RESPONSE TO TREATMENT: Severity of drooling can be assessed subjectively via discussion with patients and their carers/parents and by observation. Amount of drooling can be quantified by measuring the number of bibs required per day and this can also be graded using the Thomas-Stonell and Greenberg scale: • 1 = Dry (no drooling) • 2 = Mild (moist lips) • 3 = Moderate (wet lips and chin) • 4 = Severe (damp clothing) CONSIDERATIONS FOR PRESCRIBING/TITRATION No evidence to support the use of one particular treatment over another. Drug choice is to be determined by individual patient factors. When prescribing/titrating antimuscarinic drugs to treat hypersalivation always take account of: • Coexisting conditions (for example, history of urinary retention, constipation, glaucoma, dental issues, reflux etc.) • Use of other existing medication affecting the total antimuscarinic burden • Risk of adverse effects Titrate dose upward until the desired level of dryness, side effects or maximum dose reached. Take into account the preferences of the patients and their carers/ parents, and the age range and indication covered by the marketing authorisations (see individual summaries of product characteristics, BNF or BNFc for full prescribing information).
