Essential inhaler medications for patients with respiratory diseases are backordered due to the coronavirus disease of 2019 (COVID-19). In hospitals, there has been a drastic increase in the use of salbutamol pressurized metered-dose inhalers (pMDIs), as well as salbutamol Diskus, leading to a decline in availability and causing interruptions in the supply chain. Patients with asthma are at higher risk of respiratory complications if they are infected with COVID-19. Salbutamol, a short-acting β-agonist (SABA), could be a life-saving medication during critical conditions...

Inhalation therapy with a nebulizer is widely used in chronic respiratory disease. Mixing inhalation solutions/suspensions for simultaneous inhalation is more convenient and might simplify the administration procedure. However, there are no data available to address the in vitro aerosol characteristics and physico-chemical compatibility of Combivent® (containing Salbutamol and Ipratropium bromide) with other inhalation solutions/suspensions. In order to investigate the in vitro aerosol characteristics and physico-chemical compatibility of Combivent® with Budesonide, Beclomethasone, and N -acetylcysteine, the appearance, pH, osmotic pressure, chemical stability, mass median aerodynamic diameter (MMAD), fine particles fraction (FPF), particle size corresponding to X50 (particle size, which accounts for 50% of the total cumulative percentage of volume of all particles), delivery rate, and total delivery of the mixed inhalation solution/suspension were tested...

BACKGROUND: Acute mountain sickness (AMS) is common in high-altitude travelers, and may lead to life-threatening high-altitude cerebral edema (HACE) or high-altitude pulmonary edema (HAPE). The inhaled drugs have a much lower peak serum concentrations and a shorter half-life period than oral drugs, which give them a special character, greater local effects in the lung. Meanwhile, short-term administration of inhaled drugs results in almost no adverse reactions. METHODS: We chose inhaled ipratropium bromide/salbutamol sulfate (combivent, COM), budesonide (pulmicortrespules, BUD), and salbutamol sulfate (ventolin, VEN) in our study to investigate their prophylactic efficacy against AMS...

BACKGROUND: Physicians consider ease of use, satisfaction, and preferences when prescribing an inhaler device. These factors may impact appropriate usage and compliance. METHODS: The objectives were to quantify the relative importance of inhaler attributes in patients currently using Combivent Respimat by eliciting preferences for performance and convenience attributes assessed by items in the Patient Satisfaction and Preference Questionnaire (PASAPQ). Using a pharmacy database, 19,964 adults in the United States who filled ≥2 Combivent Respimat prescriptions were identified...

We observed the effect of Combivent combined with glucocorticoids in the treatment of patients with AECOPD to explore a better drug treatment for AECOPD. The clinical observation of two clinical curative effective was carried out. Firstly, 100 patients were equally divided into treatment group and control group, who were given basic treatment. The control group was treated with inhalation of salbutamol sulfate and the other was with inhalation of Combivent and glucocorticoid. The clinical effect, dyspnea score, PaO2, PaCO2 and pulmonary function index were observed and compared...

The propellant-free Combivent Respimat Soft Mist Inhaler (CVT-R) was developed to replace the chlorofluorocarbon-propelled Combivent metered-dose inhaler (CVT-MDI). This steady-state pharmacokinetic (PK) substudy evaluated drug lung-delivery efficiency, using data from two phase III safety and efficacy trials. PK parameters were obtained from well-controlled population PK analyses. Area under the plasma concentration-time curve (AUC), maximum observed plasma concentration (C(max)), and minimum observed plasma concentration (C(min)) showed systemic exposure to ipratropium bromide and albuterol delivered via the CVT-R was proportional to ex-mouthpiece delivered dose...

BACKGROUND: The interleukin (IL)-32/tumor necrosis factor (TNF) a pathway is supposed to play a key role in the amplification of the immune response in chronic obstructive pulmonary disease (COPD) inflammation. Inhaled corticosteroids (ICS) in combination with long-acting β2-agonists (LABA) have shown airway anti-inflammatory effects in recent studies, but the mechanism is still uncertain. METHODS: Patients were treated in a randomized, open-labeled, parallel group clinical trial with either a combination of salmeterol xinafoate/fluticasone propionate (SF; Seretide, GlaxoSmithKline) Diskus (50/500 µg twice daily) or ipratropium bromide/salbutamol (IS; Combivent, Boehringer Ingelheim) MDI (42 µg/240 µg quartic daily) for 12 weeks...

Respiratory toxicity, injury and treatment following vapor inhalational exposure to the chemical warfare nerve agent (CWNA) soman (GD) were examined in non-anesthetized rats. This study exposed male Sprague-Dawley rats (250-300g) to 520, 560, 600, 825 or 1410mg×min/m(3) of soman in a customized head-out inhalation system. Signs of CWNA-induced cholinergic crises were observed in all soman-exposed animals. The LCt50 of vaporized soman as determined by probit analysis was 593.1mg×min/m(3). All animals exposed to 825 and 1410mg×min/m(3) developed severe convulsions and died within 4-8min post-exposure...

BACKGROUND: In chronic obstructive pulmonary disease (COPD) the clinical efficacy of bronchodilator therapy delivered via a nebulizer versus an aerochamber on FEV1 is controversial. No studies comparing changes in inspiratory pulmonary function parameters (ILPs) using these inhaler devices are currently available. This information might be of interest because due to dynamic bronchial compression, the relationship between the ILPs and dyspnea is more reliable than that between FEV1 and dyspnea...

Combinations of a muscarinic receptor antagonist (MA) and a β(2)-adrenoceptor agonist (BA) improve bronchodilation in COPD patients to a greater extent than drugs with either mechanism alone. Here, using an in vivo model of bronchoprotection in guinea pigs, we characterize a single agent with dual-acting MA and BA activity, THRX-200495 (MABA). THRX-200495 was compared to a fixed-dose combination of a short-acting muscarinic receptor antagonist (SAMA) and a β(2)-adrenoceptor agonist (SABA). The SAMA/SABA combination consisted of a 1:5...

We compared the efficacy and safety of ipratropium bromide/albuterol delivered via Respimat inhaler, a novel propellant-free inhaler, versus chlorofluorocarbon (CFC)-metered dose inhaler (MDI) and ipratropium Respimat inhaler in patients with COPD. This was a multinational, randomized, double-blind, double-dummy, 12-week, parallel-group, active-controlled study. Patients with moderate to severe COPD were randomized to ipratropium bromide/albuterol (20/100mcg) Respimat inhaler, ipratropium bromide/albuterol MDI [36mcg/206mcg (Combivent Inhalation Aerosol MDI)], or ipratropium bromide (20mcg) Respimat inhaler...

IMPORTANCE OF THE FIELD: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality throughout the world. Combination therapy with albuterol and ipratropium bromide was approved > 15 years ago for the treatment of COPD. We review the mechanism of action, clinical efficacy, and safety of albuterol, ipratropium and combined albuterol-ipratropium therapy. AREAS COVERED IN THIS REVIEW: We conducted a PubMed literature search using the keywords COPD, albuterol, ipratropium bromide and Combivent (Boehringer Ingelheim Corp...

The purpose of this research was to compare two cascade impaction devices for the aerodynamic particle size assessment of a combination metered-dose inhaler (MDI) product, Combivent. Particle size analysis was performed using an Anderson Mark II cascade impactor (ACI) and a Next Generation Pharmaceutical Impactor (NGI), both fitted with a preseparator and either a 1 L glass chamber or USP throat, and operated at various flow rates. Particle size distributions (PSDs) and dose delivery profiles were assessed by means of the mass median aerodynamic diameter (MMAD), geometric standard deviation (GSD), fine particle fraction <5 micron aerodynamic diameter (FPF(<5 microm)), and induction port deposition fraction (IPF)...

Pharmacological aerosols of precisely controlled particle size and narrow dispersity can be generated using the spinning-top aerosol generator (STAG). The ability of the STAG to generate monodisperse aerosols from solutions of raw drug compounds makes it a valuable research instrument. In this paper, the versatility of this instrument has been further demonstrated by aerosolizing a range of commercially available nebulized pulmonary therapy preparations. Nebules of Flixotide (fluticasone propionate), Pulmicort (budesonide), Combivent (salbutamol sulphate and ipratropium bromide), Bricanyl (terbutaline sulphate), Atrovent(ipratropium bromide), and Salamol (salbutamol sulphate) were each mixed with ethanol and delivered to the STAG...

Bronchodilators are the mainstay of therapy for patients with established chronic obstructive pulmonary disease (COPD) but, at present, the majority of patients use short-acting agents. There is increasing evidence that long-acting agents, such as the beta(2)-adrenoceptor agonists salmeterol and formeterol, and the new anticholinergic tiotropium bromide provide a better therapeutic option. In the treatment of COPD, long-acting beta(2)-adrenoceptor agonists (LABAs) given twice daily cause the same degree of bronchodilation as tiotropium bromide given once daily...
