Filter by:To humidify gases during non invasive ventilation, both to heated humidifier (HH) and heat and moisture exchanger (HME) are routinely used. Patients receiving non invasive ventilation for acute respiratory failure were randomized to HME or HH. The purpose of this study was to evaluate respiratory parameters and arterial blood gases (ABG) of patients during NIV with small dead space HME compared to HH.
PEP03 is a new chemical entity developed as a highly selective, potent, and orally active 5-LO inhibitor. PEP03 exerts its action by blocking the generation of both cysteinyl LTs and LTB4. These LTs have been associated with the inflammatory response in the lung and with the clinical sequelae, including bronchospasm. Preclinical pharmacological in- vitro, ex-vivo and in-vivo testing indicates that PEP03 has multiple beneficial actions including prevention of bronchoconstriction, and reduction of vascular leakage, cellular infiltration, and bronchial hyperresponsiveness. Clinical studies in asthmatic patients indicate that PEP03 improved FEV1 and other secondary endpoints, such as morning and evening peak flow, daytime and nighttime symptoms score, beta-agonist use, physician’s and patient’s global impression of change. Since leukotrienes have been suggested to be involved in the pathophysiology of COPD, this study is designed to explore the clinical utility of PEP03 for the treatment of moderate COPD.6; 7; 8; 9

The purpose of this study is to compare Symbicort in a pressurized metered-dose inhaler (pMDI) with formoterol and placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD).
The purpose of this study is to compare a combination asthma drug (Symbicort) with its two components, budesonide and formoterol, taken individually or in combination, and with placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD)
Human and animal studies have shown that inhaled corticosteroids (ICS) decrease airway blood flow . This effect is immediate (within 30 minutes), transient (lasting 90 minutes), and in animal studies independent of gene expression. In COPD patients, decrease in bronchial blood flow may also decrease mucosal edema, airway resistance and improve small airway function. If such an effect exists, then we should be able to measure improvements in airway conductance and reduce lung hyperinflation, which would have salutary effects on dyspnea and exercise endurance. To our knowledge, no study has examined the immediate effect of ICS on small airway function in COPD. The purpose of this study is to examine the effects of nebulized Pulmicort on small airway function (spirometry, plethysmographic lung volumes, airways resistance, closing volume, partial flow-volume loop analysis) and exercise endurance in patients with moderate to severe COPD. HYPOTHESIS 1. Nebulized ICS will immediately improve airway function compared with placebo (nebulized saline). 2. Enhanced lung emptying and reduced operating lung volumes during rest and exercise following ICS therapy will translate acutely into clinically important reductions in exertional dyspnea and improvements in exercise endurance.
In people with mild COPD, the ability to exhale air from the lungs is partly limited because of narrowing and collapse of the airways. This results in the trapping of air within the lungs and over-distention of the lungs and chest (lung hyperinflation). Breathing at high lung volumes (hyperinflation) is an important cause of breathing discomfort (dyspnea) in people with COPD. Bronchodilators help to relax muscles in the airways or breathing tubes. Bronchodilators are often prescribed if a cough occurs with airway narrowing as this medication can reduce coughing, wheezing and shortness of breath. Bronchodilators can be taken orally, through injection or through inhalation and begin to act almost immediately but with the effect only lasting 4-6 hours. The main purpose of this study is to examine the effects of inhaled bronchodilators on breathing discomfort and exercise endurance in patients with mild COPD.
