In particular, it has been documented that montelukast can cause bronchodilation as soon as within 2 hours of oral administration. Expert Rev. This section does not cite any sources. Brovana Inhalation Solution.  They should not be used without an accompanying steroid due to an increased risk of severe symptoms, including exacerbation in both children and adults. Cochrane Database Syst. Pressurized metered dose inhaler and DPIs have their advantages and disadvantages. doi: 10.1183/13993003.02165-2015, Pedersen, S., Dubus, J. C., Crompton, G. K., and ADMIT Working Group (2010). At week 26 FEV1 AUC 0–12 h was significantly higher with QVA149 than with SAL/FP, with a similar incidence of serious adverse events. Chest 113, 957–963. This combinations have a synergistic effect rather than just being additive one (Tashkin and Ferguson, 2013). Med. 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). These drugs represent 2 different classes of medications (an anticholinergic and a LABA) that have different effects on clinical and physiological indices. Chest 145, 981–991. Two 24-weeks, randomized, double blind, and placebo controlled phase III trials: PINNACLE-1 and PINNACLE-2 assessed the clinical efficacy and safety of GLY/FF 18/9.6 μg fixed dose association in patients with moderate and very severe COPD (Martinez et al., 2017b). Geneva: WHO. doi: 10.1016/j.drudis.2014.08.004. Theophylline relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels and reduces airway responsiveness to histamine, methacholine, adenosine, and allergen. (2015). International nonproprietary name (INN): Trade (brand) name. Chest 152, 1169–1178. Mahler, D. A., D’Urzo, A., Bateman, E. D., Özkan, S. A., White, T., Peckitt, C., et al. Some studies investigated satisfaction, preference, and error occurrence of these DPIs. The cornerstones of treatment are bronchodilator drugs of two different classes: beta agonists and muscarinic antagonists. Beta-adrenoceptor desensitisation is associated with β 2-agonist activation and differs depending on the cell type. Res. Appleton, S., Poole, P., Smith, B., Veale, A., Lasserson, T. J., and Chan, M. M. (2006). 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 … (2018). doi: 10.4104/pcrj.2010.00043, Pera, T., and Penn, R. B. We summarize the principal studies: a 24 weeks trial UMEC/VIL 125/25 μg once daily (OD) was tested vs. UMEC 125 μg, VIL 25 μg and placebo (OD) in more than 1000 COPD patients.

Global initiative for chronic obstructive Lung disease [GOLD] (2018). 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. 102, 1511–1520.
Med. Inhalation devices can be distinguished in three types: pressurized metered dose inhalers (pMDIs), dry powder inhalers (DPIs) and, recently, soft mist inhaler (SMI, Boehringer Ingelheim).

Indeed, in DPIs the inhalation maneuver is crucial and reflects the deposition rate of active principle in the respiratory tract; each DPI device has a different inhalation maneuver and the ability to perform a correct process is dependent from patient’s characteristics such as age and clinical condition (Brocklebank et al., 2001; Lavorini et al., 2008; Pedersen et al., 2010; Inhaler Error Steering Committee et al., 2013; Lexmond et al., 2014). |, Pharmacology Mechanism of Action and Rationale for LAMA/LABA Fixed Dose Combinations in a Single Inhaler for COPD, LAMA/LABA Fixed Dose Combinations in a Single Inhaler for COPD: Evidences From Clinical Trials, The Role of LAMA/LABA Fixed Dose Combinations in a Single Inhaler for COPD Therapy in Global Initiative for Obstructive Lung Disease Recommendations, Critical Issues for LABA/LAMA Combinations in a Single Inhaler Therapy for COPD, Global initiative for chronic obstructive Lung disease [GOLD], 2018, Inhaler Error Steering Committee et al., 2013, https://clinicaltrials.gov/ct2/show/NCT03265145?term=NCT03265145&rank=1, https://goldcopd.org/wp-content/uploads/2017/11/GOLD-2018-v6.0-FINAL-revised-20-Nov_WMS.pdf, Creative Commons Attribution License (CC BY). Table 2. Because of the differences in the mechanisms of action, it has been hypothesized that LAMAs and LABAs might have a synergistic effect if combined. doi: 10.1016/j.rmed.2017.03.015, Horita, N., Goto, A., Shibata, Y., Ota, E., Nakashima, K., Nagai, K., et al. Tiotropium in combination with placebo, salmeterol, or fluticasone-salmeterol for treatment of chronic obstructive pulmonary disease: a randomized trial. Figure 1. Unfortunately, only few studies attempting to identify the optimal LABA/LAMA dose combination in COPD patients have been conducted, and the majority of them simply confirmed the hypothesis that the combination of two bronchodilator agents with different mechanisms of action provided improvements in lung function, compared to monotherapy with either … Principal differences between inhaler devices used to deliver LAMA/LABA FDC. Concurrent use of indacaterol plus tiotropium in patients with COPD provides superior bronchodilation compared with tiotropium alone: a randomised, double-blind comparison. doi: 10.1080/14656566.2017.1403583, Lange, P., Marott, J. L., Vestbo, J., Olsen, K. R., Ingebrigtsen, T. S., Dahl, M., et al. Trough FEV1 at week 26 was significantly improved with QVA149 compared to all other treatment arms, with a safety and tolerability profile similar to placebo. However, a number of questions is still pending and under debate. 102, 593–604. Mechanism : Salbutamol is a beta2-adrenergic agonist. Glucocorticoids work by modulating gene expression. Twice-daily LABAs are formoterol fumarate (FF) or propionate (FP) and salmeterol (SAL). Figure 2. Importantly, a LABA does not decrease any of the underlying inflammation associat… Lung Disease Research Group, Departments of Pharmacology and Medicine, University of Melbourne, … The combined therapy with LABA and LAMA plays an important role in therapeutic strategies three out of four ABCD groups: Group B: in group B, characterized by patients with high symptoms burden but low number of moderate/severe exacerbations, the initial therapy should be based on a long acting bronchodilator, LABA or LAMA (Barr et al., 2005; Appleton et al., 2006). Patients belonging to group D could be naive patients (at first diagnosis), or could be shifted to this group coming from group B, in case of increased number of exacerbations during the previous year, or from group C, in case of increase of symptoms’ burden. (2013). Efficacy of tiotropium-olodaterol fixed-dose combination in COPD. 2:CD012066. A systematic review with meta-analysis of dual bronchodilation with LAMA/LABA for the treatment of stable COPD.

Mechanism of action. In summary the considered trials concluded that once-daily UMEC/VIL 62.5/25 μg OD, was well-tolerated, provided clinically-significant improvements in lung function and symptoms in COPD patients. Pharmacol. Lancet. Med. BMC Pulm. Med. (2012). 374, 2222–2234. The study was designed to assess not only the value of triple therapy compared to dual therapy, but also the relative comparative advantages of the two dual therapies (ICS/LABA and LABA/LAMA) (Pascoe et al., 2016).
