Acute angle closure can be seen as a side effect of some medications that can be used systemically. In this article, clinical characteristics of 54-year-old female patient who applied to our clinic with bilateral acute angle closure and has been received nebulized form of salbutamol and ipratropium bromide due to asthma for 4 days was evaluated. Right and left eye IOP were measured as 50 and 48 mmHg. IOP was reduced with anti-glaucomatous treatment. and peripheral iridectomy was done, and then the patient was discharged...

BACKGROUND: Status asthmaticus is an acute exacerbation of asthma that is persistent and intractable and remains unresponsive to initial treatment with bronchodilators and systemic corticosteroids and that can result in hypoxemia, hypercarbia, and secondary respiratory failure. METHOD: We reviewed treatment and recent patents on management of status asthmaticus. CONCLUSIONS: Supplemental oxygen should be given to maintain an oxygen saturation of ≥92% in room air...

Arginine is a critical amino acid in specific cancer types including hepatocellular carcinoma (HCC) and melanoma. Novel molecular mechanisms and therapeutic targets in arginine metabolism-mediated cancer formation await further identification. Our laboratory has previously demonstrated that arginine metabolic enzyme argininosuccinate lyase (ASL) promoted HCC formation in part via maintenance of cyclin A2 protein expression and arginine production for channeling to nitric oxide synthase. In this study, we investigated the mechanism by which ASL regulates cyclin A2 expression...

BACKGROUND: The aim of this study was to evaluate the responsiveness of the 3-minute constant rate step test (3-MST) to detect the relief of exertional dyspnea (respiratory discomfort) after acute bronchodilation in COPD patients. PATIENTS AND METHODS: A total of 40 patients with moderate-to-severe COPD (mean forced expiratory volume in 1 second: 45.7 (±14.7), % predicted) performed four 3-MSTs at randomly assigned stepping rates of 14, 16, 20 and 24 steps/min after inhalation of nebulized ipratropium bromide (500 µg)/salbutamol (2...

BACKGROUND: COPD is defined as partly irreversible airflow obstruction. The response pattern of bronchodilators has not been followed in advanced lung function parameters. PURPOSE: The aim of this study was to investigate bronchodilator response pattern in advanced lung function parameters in a continuous fashion along forced expiratory volume in 1 second (FEV1) percent predicted (%p) in COPD patients and controls. PATIENTS AND METHODS: Eighty-one smokers/ex-smokers (41 controls and 40 COPD) performed spirometry, body plethysmography, impulse oscillometry and single-breath helium dilution carbon monoxide diffusion at baseline, after salbutamol inhalation and then after an additional inhalation of ipratropium...

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 an 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...

This study aimed to investigate the role of M3 acetylcholine receptor (M3-AChR) expression in airway remodeling. Additionally, we aimed to evaluate the effects of ipratropium bromide solution inhaled in an early phase of asthma on airway remodeling in ovalbumin (OVA)-sensitized and challenged mice. Thirty BALB/c mice were divided into three groups, namely, control group (saline sensitized/challenged mice), asthma group (OVA sensitized/challenged mice), and treatment group (OVA sensitized/challenged mice treated by ipratropium bromide)...

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...
