The aim of pharmacological treatment is to reduce symptoms, the risk and severity of exacerbations in addition to improve health status and tolerance to exercise (Global initiative for chronic obstructive Lung disease [GOLD], 2018). A self-management programme comprising of a written personalised action plan and education should be offered to all patients with asthma (and/or their family or carers), and should be supported with regular review by a healthcare professional. Taking into account the lung function, all the studies included in the meta-analysis demonstrated an improvement in pre-bronchodilator FEV1 at the end of the study for the LABA + TIO groups. Ipratropium bromide is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally-mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released at the neuromuscular junctions in the lung. doi: 10.1164/rccm.201209-1665OC, Vestbo, J., Papi, A., Corradi, M., Blazhko, V., Montagna, I., Francisco, C., et al. The rate of moderate or severe exacerbations was significantly reduced with ACL/FF 400/12 μg compared with placebo (p < 0.05) but not monotherapies. Respir. In a separate study versus SPIRIVA HANDIHALER, statistical significance cannot be inferred. Health Technol. (2017). (2012). J. It is also desirable that a new LABA should demonstrate fast onset of action, and a safety profile at least comparable to existing LABAs. Several long-acting β adrenoreceptor agonists have a duration of action of 24 hours, allowing for once-daily dosing. In addition to their bronchodilator action, LABA also inhibit mast cell mediator release, plasma exudation and may reduce sensory nerve activation. The efficacy and safety of this combination was studied several randomized, double-blind, parallel-group, multicenter trials (Derom et al., 2016). Chronic obstructive pulmonary disease (COPD) is believed to be the third leading cause of death worldwide by 2020 (WHO, 2008). Assessment in a Real World Setting of the Effect of Inhaled Steroid-Based Triple Therapy Versus the Combination of Tiotropium and Olodaterol on Reducing Chronic Obstructive Pulmonary Disease (COPD) Exacerbations [AIRWISE]. ACL/FF 400/12 is commercialized with the names of Duaklir® and Brimica®, delivered by the Genuair® dry powder inhaler (available only in European market). Improvements in lung function with umeclidinium/vilanterol versus fluticasone propionate/salmeterol in patients with moderate-to-severe COPD and infrequent exacerbations. Budesonide is an inhaled corticosteroid (ICS) that works by reducing and preventing respiratory tract inflammation, while formoterol is a long-acting beta2-agonist bronchodilator (LABA) that decreases resistance in the respiratory airway and increases … SLIDESHOW What is Asthma? Glucocorticoids achieve this by binding to receptors in cytosol – known as glucocorticoid receptors (GR). COPD is a disabling disease with huge impact on normal daily activities and limiting quality of life, the disease abruptly worsen due to exacerbations inducing a step down of health conditions, following which the recovery of breath function and activities is gradually slower and more difficult leading to disability and death (Global initiative for chronic obstructive Lung disease [GOLD], 2018). (2013). Beta2-adrenoceptors: mechanisms of action of beta2-agonists The human beta2-adrenoceptor is a member of the 7 transmembrane family of receptors. Drug Deliv. Clusters of comorbidities based on validated objective measurements and systemic inflammation in patients with chronic obstructive pulmonary disease. Lung deposition of fenoterol and flunisolide delivered using a novel device for inhaled medicines: comparison of RESPIMAT with conventional metered-dose inhalers with and without spacer devices. Global initiative for COPD suggests the use of long acting beta agonists (LABA) and long acting muscarinic antagonists (LAMA) in combination for group B patients with persistent symptoms, group C patients with further exacerbations on LAMA treatment and for group D patients with or without the addition of inhaled corticosteroids (ICSs). Marvell 22 Sep 2009. doi: 10.1016/j.rmed.2017.03.015, Horita, N., Goto, A., Shibata, Y., Ota, E., Nakashima, K., Nagai, K., et al.   Gary P. Anderson. 3,4,5,6,7,8,9 This action can also be additive to the bronchodilation caused by the concomitant use of a beta agonist. Long acting beta agonist can be divided into once-daily and twice-daily LABA. Curr. Symptoms of bronchospasm include shortness of breath, wheezing, coughing and chest tightness. The flow rate able to activate the different inhalers, the need for greater or less coordination of the patient and the preferences of the patients regarding the “taste” of the different formulations are all elements that will play a fundamental role not yet studied in the daily clinical application of these formulations. (2017a). Answers (1) MA. Expert Opin. Due to the combination of smaller particle size, lower velocity and longer duration of the nebulization, a smaller dose of bronchodilators ensure the same level of efficacy and safety than metered dose inhalers. Another disadvantage of pMDIs is the propellant; previously chlorofluorocarbon (CFC) was used now substituted by hydrofluoroalkane (HFA) and this can cause the inhaler to be more expensive. TIO/FF is commercialized only in few countries with the name of DUOVA® (Lebanon) with different dosages (9/6 mcg; 9/12 mcg and 18/12 mcg) and TIOFORM® (India) 18/12 mcg; 9/6 mcg. GLY/IND association 50–110 μg is marketed in EU with the brand name of Ultibro®, delivered by Neohaler®DPI. This combinations have a synergistic effect rather than just being additive one (Tashkin and Ferguson, 2013). doi: 10.1089/jam.2005.18.264, Rajan, S. K., and Gogtay, J.

LABA Monotherapy vs Continued Therapy With ICS in Patients With Persistent Asthma: A Randomized Controlled Trial SOCObjective: To examine the effectiveness of salmeterol as replacement therapy inpatients whose asthma is well controlled by low-dose TAPatient 164 patients, 12-65 … FLAME A 52-week multi-center, parallel-group, active controlled study to compare the effect of QVA149 OD with SAL/FP TD on the rate of exacerbations in 3332 patients with moderate-to-very severe COPD. Asthma Myths Debunked See Slideshow. 10, 1023–1031. The 400/12 μg combination induced a Peak FEV1 improvement at 24 weeks by 285 ml versus placebo (p < 0.0001) and the 400/6 μg combination by 259 ml with versus placebo (p < 0.0001). It has shown a significant improvement in lung function for the FDC compared to monocomponents and in HRQL and RMu compared to placebo (Mahler et al., 2015). The vast majority of DPIs are breath-actuated devices, using a passive mechanism, without the need of patient-device coordination; for a proper dose release the patient is required to make a minimal inspiratory effort. Lancet. doi: 10.2147/COPD.S72762, Lal, C., and Strange, C. (2017). Comparison of tiotropium once daily, formoterol twice daily and both combined once daily in patients with COPD. Respir. 1, 524–533. AR, VF, FP, and PP contributed to various parts of the text and wrote the manuscript. Searching for the synergistic effect between aclidinium and formoterol: from bench to bedside. As before discussed each inhaler type has pros and cons that must be considered in the selection of a device for a particular patient. Formoterol mono- and combination therapy with tiotropium in patients with COPD: a 6-month study. B. J. However, the results of head to head comparison between LAMA/LABA and LAMA/LABA/ICS combinations are still pending. The challenge of delivering therapeutic aerosols to asthma patients. Med. Thus these two classes of drug address complementary aspects of the pathophysiology of asthma that neither drug class is able to achieve alone. The rate required to deliver the medication in pMDI inhalers is low (about 30 L/min) while the rate required for DPIs is higher (differs based on the build of the inhaler). Respir. The One Muscarinic Agonist. J. Chron. doi: 10.1016/S0140-6736(18)30206-X, Pascoe, S. J., Lipson, D. A., Locantore, N., Barnacle, H., Brealey, N., Mohindra, R., et al. Obstruct. The incidence of pneumonia was threefold lower with QVA149 (0.8%) (Zhong et al., 2015). Impact Factor 4.225 | CiteScore 5.0More on impact ›, New Perspectives in Assessment, Phenotyping and Pharmacological Treatment of Chronic Obstructive Pulmonary Disease (COPD) Med. Same results have been obtained in DYNAGITO trial with TIO/OLO dual therapy versus TIO alone (Calverley et al., 2018). Med. The effects of a LABA can last 5 to 12 hours depending on how frequently you use this inhaler. Triple therapy also resulted in a lower rate of hospitalization due to COPD than UMEC/VIL association (Lipson et al., 2018). In the clinical trials these problems have never been observed and all LAMA/LABA FDC have shown optimal tolerability profiles. Vilanterol is another LABA with a quick onset of action, however, ICS/LABA inhalers containing vilanterol have not been studied as single inhaler treatment and are not indicated for this use. Moreover LAMA/LABA combinations have been noted to be superior compared to LABA/ICS combined treatment for COPD with at least one exacerbation in the previous year (Wedzicha et al., 2016). Moreover LAMA/LABA direct comparison in head-to-head trials would be suggested. MM and AR conceived the idea of the manuscript. British Thoracic Society & Scottish Intercollegiate Guidelines Network (SIGN). Respir. The FDA approved dose for GLY/IND in the US is 15.6/27.5 μg TD based on the FLIGHT1 and FLIGHT2 studies (Mahler et al., 2015) while in the European Union the approved dose for GLY/IND is 50/110 μg OD. Until now, the experiences reported in the daily clinical practice have given encouraging results, but we should keep the guard high in the detection of possible tolerance problems, especially in complex patients with multiple associated diseases usually excluded from clinical trials. Care Med. Med. Salmeterol is the result of a specific research program designed to achieve prolonged duration of action by molecular modification of the short-acting β2-agonists salbutamol. However, only the observation in real life clinical setting can reassure us about this aspect. QVA149 had significant superiority to SAL/FP for tFEV1 and for the standardized AUC from 0 to 4 h. QVA149 showed similar improvements in TDI focal score, St George Respiratory Questionnaire total score, and RMu compared to the other active arm. They are designed to reduce the need for shorter-acting β2 agonists such as salbutamol (albuterol), as they have a duration of action of approximately 12 hours in comparison with the 4-to-6-hour duration of salbutamol, making them candidates for sparing high doses of corticosteroids[citation needed] or treating nocturnal asthma and providing symptomatic improvement in patients with COPD. (2014). Med. Clearly none of the pharmacological treatments have ever shown a significant impact on COPD mortality, however we believe that the effects of the LABA/LAMA combination treatment observed improving patient quality of life represent main issues in the treatment of COPD. Search for more papers by this author. Non-inferiority of GLY/IND to UMEC/VIL could not be declared although between-treatment differences were not clinically relevant (Kerwin et al., 2017). Bronchodilator efficacy of tiotropium-formoterol via single pressurized meter dose inhaler (pMDI) versus tiotropium alone in COPD. M3 receptors are coupled (GTP) – binding protein (G2) which regulates intracellular calcium concentration and calcium-modulated proteins (Pera and Penn, 2014) (Figure 2). Efficacy of tiotropium-olodaterol fixed-dose combination in COPD. Res. Lung Disease Research Group, Departments of Pharmacology and Medicine, University of Melbourne, Parkville, 3010 VIC, Australia . The main published studies on LAMA/LABA single inhaler treatments are summarized in Table 2. Currently the LAMA/LABA combination in single inhaler device disposable on the market include Umeclidinium/ Vilanterol (Anoro®), Tiotropium/Olodaterol (Stiolto®), Glycopyrrolate/Formoterol (Bevespi®) and Glycopyrronium/Indacaterol (Ultibron®) available in the United States. The devices are substantially divided in: active devices, where the energy needed to create the aerosol is generated by the same inhaler through a complex technological system, and passive devices where the aerosolization of the drug is dependent from the inhaled air stream. Tiotropium versus salmeterol for the prevention of exacerbations of COPD. (2008). Combination therapy involving the bronchodilator action of a LABA and a LAMA for moderate to severe COPD has been shown to be more effective than single bronchodilator monotherapy (either a LABA or LAMA in a single inhaler) due to the complementary mechanism of action of … Despite its worldwide democratization, owing to its clinical efficacy, high safety profile and cheap cost, the exact mechanism(s) of action of this anti-hyperglycemic molecule with pleiotropic properties still remains to be fully elucidated. Research has focused on the following parameters … They reported that both associations treatments were superior to TIO, UMEC, and VIL alone in improving tFEV1 and RMu (Decramer et al., 2014). UMEC/VIL 55–22 μg is commercialized with the name of Anoro® and delivered by the Ellipta® dry powder inhaler (DPI). With the exception of formoterol, long-acting β2 agonists are not recommended for the treatment of acute asthma exacerbations because of their slower onset of action compared to salbutamol. Mechanism of action. QVA149 reduced the annual rate of all COPD exacerbations (the rate was 11% lower in the QVA149 group than in the SAL/FP group) (Wedzicha et al., 2016). Group D: in group D, characterized by patients with high symptoms burden and high number of moderate/severe exacerbations, the initial therapy should be based on a combination bronchodilator therapy LAMA/LABA. In particular It should be noted that the GLY/IND associations in the US is available only at a lower dosage than that used in clinical trials (Vogelmeier et al., 2013; Zhong et al., 2015; Wedzicha et al., 2016) in relation to the differences in the US-approved IND dosage compared to the one approved in the EU. 1, 199–209. 19:CD001104. (2015). 374, 2222–2234. doi: 10.1002/14651858.CD002876.pub2, Bateman, E. D., Chapman, K. R., Singh, D., D’Urzo, A. D., Molins, E., Leselbaum, A., et al. There were no asthma-related deaths and few asthma-related serious adverse events when salmeterol is used with an inhaled steroid. Another (Maleki-Yazdi et al., 2014) 24-week, multicenter, randomized, blinded, double-dummy, parallel-group study Phase III study compared UMEC/VIL 62.5/25 μg, to TIO 18 μg OD. doi: 10.1111/j.1476-5381.2012.01881.x, Inhaler Error Steering Committee, Price, D., Bosnic-Anticevich, S., Briggs, A., Chrystyn, H., Rand, C., et al.

Here we resemble the principle international studies on efficacy and safety of LAMA/LABA combinations. Comparison between TIO/OLO 5/5 μg FDC OD and OLO 5 μg OD, was generally statistically but not clinically significant in favor of fixed dose association not reaching the minimal clinical important difference (MCID). ACh, acetylcholine; M1, M1-muscarinic receptor; M2, M2-muscarinic receptor; M3, M3-muscarinic receptor. 85, 960–964. For these reasons clinical trials aimed at the ability to detect different endpoints capturing different aspects of COPD pathobiology such as real life clinical improvement are claimed. In those patients with persistent exacerbations, the addition of a second long acting bronchodilator or a combination of a LABA and an ICS may be beneficial (Miravitlles et al., 2017). ICS=inhaled corticosteroids; LABA=long-acting β 2-agonists; OCS=oral corticosteroids; SOC=standard of care. However, a number of questions is still pending and under debate. doi: 10.1016/j.pupt.2010.03.003, Celli, B., Crater, G., Kilbride, S., Mehta, R., Tabberer, M., Kalberg, C. J., et al.
