Plain language summary
Adding the LAMA tiotropium Respimat inhaler to combination LABA/ICS inhaler may reduce the need for rescue oral steroids. A noticeable benefit on quality of life is unlikely, and we couldn't tell if it reduced hospital admissions, but adding tiotropium has some benefit on lung function, asthma control, and non‐serious side effects.
Abstract
Background: Maintenance treatment with long‐acting beta 2 ‐agonists and inhaled corticosteroids (LABA/ICS) can relieve asthma symptoms and reduce the frequency of exacerbations, but there are limited treatment options for people who do not gain control on combination LABA/ICS.

Tiotropium in chronic obstructive pulmonary disease – a review of clinical development. An infographic that provides a summary of the clinical trial results of tiotropium in chronic obstructive pulmonary disease
How long does ipratropium dissociate?
Ipratropium has a short duration of action, with a dissociation half-life of 0.3 h from the M3 receptor and requires four-times-a-day (QID) dosing, potentially affecting adherence to therapy [ 4, 5 ]. In contrast, tiotropium has a long duration of action, enabling once-daily (QD) dosing [ 5 ].
What is a DPI inhaler?
DPIs, pressurized metered-dose inhalers (pMDIs), and SMIs are used for delivery of inhaled COPD medications. However, patients with COPD might not be able to generate the inspiratory flow necessary for optimal drug de-aggregation and lung deposition with DPIs [ 11 ]. DPIs with varying internal resistances are available [ 11 ], and patients’ peak inspiratory flow should ideally be assessed before prescribing a DPI [ 12 ]. Further, the velocity of the aerosol from pMDIs and the inability of some patients with COPD to properly coordinate actuation and inhalation when using pMDIs can lead to considerable oropharyngeal drug deposition [ 11 ]. Use of a spacer or holding chamber with a pMDI helps slow the velocity of aerosolized particles; removes larger, nonrespirable particles; and reduces oropharyngeal deposition [ 13 ]. Respimat®, the only available SMI, is a propellant-free inhaler that uses mechanical energy to generate a fine, slow-moving mist [ 14 ]. Respimat® provides a higher lung drug deposition than pMDIs or DPIs [ 15, 16, 17 ], delivers the dose of medication independent of the patient’s inspiratory effort [ 18 ], and requires minimal coordinated actuation and inhalation [ 19, 20 ], thereby making it suitable for a range of patients with COPD [ 14 ].
Why was Tiospir conducted?
TIOSPIR® was conducted because a numerical, but not statistically significant, imbalance in the number of deaths had been noted in meta-analyses of Respimat® trials , between tiotropium Respimat® and placebo Respimat® or tiotropium HandiHaler®, particularly for patients with known cardiac disorders [ 85, 86, 87 ]. Valid concerns were quickly raised, however, about the meta-analyses’ methodologies and conclusions, particularly the analysis conducted by Singh et al. [ 85 ], which included five of the aforementioned RCTs [ 27, 28, 29, 88, 89, 90 ]. For example, in that analysis, conclusions were based on three 1-year studies that had mortality imbalances (and not based on two 12-week studies that showed no imbalance) [ 88 ]. Additionally, in one of the studies with mortality imbalances, the placebo arm had an unusually low (0.77%) mortality rate compared with that observed in other studies (1.5–2.5% or higher) [ 88 ]. Further, fatal cases were incorrectly assigned to treatment groups [ 88, 91 ], and a 6-month trial of > 850 patients [ 92 ], which had only two deaths in the tiotropium Respimat® arm and five deaths in the placebo Respimat® arm, was not included [ 88, 91 ]. Moreover, two doses of tiotropium—the marketed 5-μg dose and a non-approved, unmarketed 10-μg dose—were included in the primary analysis [ 91, 93 ]. These and other factors provide a plausible explanation for the imbalances observed in the aforementioned meta-analyses. In TIOSPIR®, a similar impact on survival was observed between tiotropium Respimat® 2.5 μg and tiotropium HandiHaler® 18 μg, which expands upon findings from UPLIFT and reinforces the safety and efficacy of tiotropium in patients with COPD, regardless of cardiac arrhythmia history [ 26, 29, 81 ].
Does tiotropium bromide inhibit acetylcholine?
LAMAs inhibit the bronchoconstrictor effect of acetylcholine by prolonged binding to the M3 muscarinic receptors present on airway smooth muscles and faster dissociation from M2 receptors [ 2, 3 ]. Tiotropium bromide, the first LAMA available for COPD in clinical practice, with a dissociation half-life of 35 h from the M3 receptor, is structurally related to ipratropium [ 4, 5 ]. Ipratropium has a short duration of action, with a dissociation half-life of 0.3 h from the M3 receptor and requires four-times-a-day (QID) dosing, potentially affecting adherence to therapy [ 4, 5 ]. In contrast, tiotropium has a long duration of action, enabling once-daily (QD) dosing [ 5 ]. Tiotropium was first available as an inhalation powder delivered via a dry-powder inhaler (DPI; Spiriva® HandiHaler®; Boehringer Ingelheim Pharmaceuticals, Inc) and later became available as an inhalation spray delivered via a soft mist inhaler (SMI; Spiriva® Respimat®; Boehringer Ingelheim Pharmaceuticals, Inc). Tiotropium HandiHaler® and tiotropium Respimat® are indicated for long-term, QD maintenance treatment of bronchospasm associated with COPD and for reducing COPD exacerbations in the United States (US), European Union (EU), and other countries [ 6, 7 ]. A LABA/LAMA combination is used to leverage their different mechanisms of action. While LAMAs prevent bronchoconstriction, LABAs relax bronchial smooth muscle and cause bronchodilation by stimulating β2-adrenergic receptors in airway smooth muscle which trigger cellular pathways [ 8 ]. Tiotropium in a fixed-dose combination with the LABA olodaterol (Stiolto® Respimat® inhalation spray [Spiolto® Respimat® inhalation solution in Europe]; Boehringer Ingelheim Pharmaceuticals, Inc) is indicated for the long-term, QD maintenance treatment of patients with COPD [ 9, 10 ].
Is tiotropium bromide safe for COPD?
Tiotropium bromide was the first LAMA available for COPD in clinical practice and, because of its long duration of action, is administered once daily. Tiotropium was initially available as an inhalation powder delivered via a dry-powder inhaler (DPI). Later, tiotropium also became available as an inhalation spray delivered via a soft mist inhaler (SMI). The SMI was designed to overcome or minimize some of the issues associated with other inhaler types (eg, the need for strong inspiratory airflow with DPIs). Results of short- and long-term randomized, controlled clinical trials of tiotropium in patients with COPD indicated tiotropium was safe and significantly improved lung function, health-related quality of life, and exercise endurance, and reduced dyspnea, lung hyperinflation, exacerbations, and use of rescue medication compared with placebo or active comparators. These positive efficacy findings triggered the evaluation of tiotropium in fixed-dose combination with olodaterol (a long-acting β 2 -agonist). In this review, we provide an overview of studies of tiotropium for the treatment of COPD, with a focus on pivotal studies.
Is tiotropium safe for lung disease?
Tiotropium is safe and efficacious as a long-term, once-daily LAMA for the maintenance treatment of COPD and for reducing COPD exacerbations. The SMI generates a low-velocity, long-duration aerosol spray with a high fine-particle fraction, which results in marked lung drug deposition.
