Spray-dried ipratropium bromide (IPB) microspheres for oral inhalation were engineered using Quality by Design. The interrogation of material properties, process parameters, and critical product quality attributes interplay enabled rational product design. A 2(7-3) screening design exhibited the Maillard reaction between L-leucine (LL) and lactose at studied outlet temperatures (OT) >130°C. A response surface custom design was used in conjunction with multicriteria optimization to determine the operating design space to achieve inhalable microparticles...

OBJECTIVE: In addition to lung volume restriction, persons with chronic tetraplegia demonstrate obstructive airway physiology evinced by pharmacologically-induced bronchodilation. We previously found independent evidence that anticholinergic agents (ipratropium bromide; IB) and beta-2 adrenergic agonists (albuterol sulfate; AS) were associated with significant bronchodilation in subjects with tetraplegia as determined via spirometry or body plethysmography. Direct comparison of these two classes of agents has received little attention...

Parasympathetic activity is increased in patients with chronic obstructive pulmonary disease (COPD) and asthma and appears to be the major reversible component of airway obstruction. Therefore, treatment with muscarinic receptor antagonists is an effective bronchodilator therapy in COPD and also in asthmatic patients. In recent years, the accumulating evidence that the cholinergic system controls not only contraction by airway smooth muscle but also the functions of inflammatory cells and airway epithelial cells has suggested that muscarinic receptor antagonists could exert other effects that may be of clinical relevance when we must treat a patient suffering from COPD or asthma...

Unilateral fixed mydriasis can be an ominous sign; however in many cases, it is benign and represents pharmacologic mediated action on the iris dilator or sphincter. Differentiation between pharmacologic mediated anisocoria and physiologic anisocoria can be challenging but may save on costly imaging. An 83 year-old woman was admitted with critical limb ischemia and subsequently developed respiratory failure treated with positive pressure ventilation and ipratropium nebulizers. She was noted to have left unilateral mydriasis without other neurologic deficits...

Tropane alkaloids and their derivatives are anticholinergic drugs with narrow therapeutic range. Here we characterize the organic cation transporters from the SLC22 (OCT1, OCT2, and OCT3) and the SLC47 families (MATE1 and MATE2-K) as potential mediators of the renal and extra-renal excretion, the two major roads of elimination of these substances. All analyzed compounds inhibited and the quaternary amine derivatives ipratropium and trospium were strongly transported by OCTs and MATEs. Overexpression of OCTs or MATEs in HEK293 cells resulted in up to 63-fold increase in the uptake of ipratropium (Km of 0...

Categorization of patients with COPD as reversible or nonreversible to a bronchodilator may change over time. This post hoc analysis aimed to determine if an individual's reversibility, when treated as a continuous variable, could predict his/her future response to two short-acting bronchodilators: albuterol and ipratropium. The analysis was completed using data from a 4-week, randomized, open-label, two-period crossover study (NCT01691482; GSK study DB2114956). Patients received albuterol (doses: UK =4×100 μg/puff; US =4×90 μg/puff) followed 1 hour later by ipratropium (4×20 μg/puff) or vice versa during treatment Period 1...

BACKGROUND: The use of chlorofluorocarbons (CFCs) has contributed to the depletion of the stratospheric ozone layer resulting in serious health concerns. Ipratropium bromide/salbutamol sulphate CFC-pressurized metered-dose inhalers (IB/SAL-CFC pMDI) have been in widespread use for many years without any apparent ill consequences. This combination has now been reformulated using the hydrofluoroalkane (HFA) propellant. This study sought to establish the clinical noninferiority of a new HFA-containing IB/SAL pMDI to the conventional IB/SAL-CFC pMDI in subjects with mild/moderate COPD...

Treatment of patients with acute severe or life-threatening asthma in the emergency department or in rescue services is a challenge for the physician. The decision on which therapy is needed depends on the clinical assessment of severity. Early administration of bronchodilators, ipratropium bromide and oral or intravenous corticosteroids is the cornerstone of treatment. If these treatments fail, systemic administration of bronchodilators, MgSO4 and theophylline should be carried in order to avoid intubation...

Management of acute viral bronchiolitis is largely supportive. There is currently no proven effective therapy other than oxygen for hypoxic children. The evidence indicates that there is no routine benefit from inhaled, rapid short-acting bronchodilators, adrenaline or ipratropium bromide for children with acute viral bronchiolitis. Likewise, there is no demonstrated benefit from routine use of inhaled or oral corticosteroids, inhaled hypertonic saline nebulisation, montelukast or antibiotics. The last should be reserved for children with severe disease, when bacterial co-infection is suspected...

INTRODUCTION: Conflicting results has been achieved in a small number of clinical studies evaluating the efficiency of magnesium sulphate (MS) in COPD exacerbations. We aimed to investigate the efficiency of nebulised MS in COPD exacerbations. PATIENTS AND METHODS: Twenty patients who met the study criteria were randomized into two groups. All patients were treated with O2, antibiotics and oral corticosteroids. Additionally one group received ipratropium bromide (IB) 500 µg together with MS 151 mg/dose, while the other group received IB together with placebo...

Current literature does not consistently show a benefit to providing medication cost information to inpatient health care prescribers. This study assessed the effectiveness of computerized provider order entry alerts that displayed the cost of a high-cost medication alongside a lower cost alternative, targeting 3 high-cost medications. Medication utilization during the one year prior to the intervention was compared to usage in the year after implementation. Reduced utilization of high-cost medications was found when comparing pre to post...

BACKGROUND: Up to 30 % of children with acute asthma are refractory to initial therapy, and 84 % of this subpopulation needs hospitalization. Finding safe, noninvasive, and effective strategies to treat this high-risk group would substantially decrease hospitalizations, healthcare costs, and the psycho-social burden of the disease. Whereas intravenous magnesium (Mg) is effective in severe refractory asthma, its use is sporadic due to safety concerns, with the main treatment goal being to prevent intensive care unit admission...

BACKGROUND: Asthma is the most common pediatric chronic disease and currently affects 7.1 million children in the United States. Many children experience acute asthma exacerbations. Many children also require hospitalization despite treatment in an emergency department with current standard therapy (corticosteroids, albuterol, and ipratropium). These hospitalizations may be avoided if effective adjunctive therapies can be developed to adequately treat severe exacerbations. METHODS: Publications were searched in the PubMed database using the following keywords: magnesium AND asthma AND children AND randomized controlled trial...

BACKGROUND: Conventional lung function parameters, such as forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and inspiratory capacity (IC) are often used to assess the therapeutic outcomes of bronchodilators, but they lack sensitivity. A novel indicator, namely efficiency of neural respiratory drive (NRD), may objectively evaluate the physiological changes in patients with chronic obstructive pulmonary disease (COPD). We investigated whether this indicator could be used to more accurately assess the responsiveness to inhaled bronchodilators...

BACKGROUND AND OBJECTIVE: Cigarette smoke exposure increases airway smooth muscle (ASM) contractility. Abnormalities in peripheral airway function in smokers with normal spirometry could be due to the effects of ASM tone. We aimed to determine the contribution of ASM tone to peripheral airway function in smokers with normal spirometry from the response to bronchodilator (BD). METHODS: Ventilation heterogeneity in peripheral conductive (Scond) and acinar (Sacin) airways were measured in 50 asymptomatic smokers and 20 never-smokers using multiple breath nitrogen washout, before and 20 min after inhalation of 200 µg salbutamol and 80 µg ipratropium bromide...
