An increased concentration of nitric oxide (NO) in the exhaled air of asthmatic patients may reflect inflammation of the airways, and exhaled NO may, therefore, be useful in monitoring asthma control and the optimal use of anti-inflammatory treatment. We have studied the effect of reducing and then increasing the dose of inhaled steroid on exhaled NO, lung function and symptoms in 14 asthmatic ...

Ciclesonide is a nonhalogenated corticosteroid that is converted to its clinically active metabolite, desisobutyryl-ciclesonide, by esterases in the airways. Pharmacodynamic studies have shown that inhaled ciclesonide has potent antiinflammatory activity in patients with asthma, and does not appear to have clinically relevant systemic effects, even at high doses. It is highly protein-bound and ...

Current guidelines recommend the use of inhaled corticosteroids (ICS) for suppression of airway inflammation in patients with asthma. Although it is well known that ICS cause dose-related adrenocortical suppression, it is less known that they can lead to iatrogenic Cushing's syndrome (CS). Fluticasone propionate (FP) is an ICS more potent than beclomethasone and budesonide. FP is metabolized as...

The absolute systemic availability and pulmonary deposition of budesonide inhaled from a pressurized metered-dose inhaler (pMDI) attached to a Nebuhaler spacer was determined in 15 healthy subjects. The study was of an open cross-over design. Each subject randomly received three single doses of budesonide on separate days: 0.5 mg given intravenously and 1.0 mg (0.2 mg x 5) by inhalation from a ...

To investigate the association between inhaled corticosteroid (ICS) exposure patterns and the risk of pneumonia in chronic obstructive pulmonary disease (COPD) patients, we performed a nested case-control study. Between 1998 and 2010, 51,739 patients, including 19,838 cases of pneumonia, were matched to 74,849 control subjects selected from a cohort of COPD patients using ICSs via risk-set samp...

BACKGROUND Budesonide inhalation suspension and the leukotriene receptor antagonist montelukast have demonstrated efficacy in children with mild persistent asthma, but comparative long-term studies in young children are needed. OBJECTIVE To compare the long-term efficacy and safety of budesonide inhalation suspension and montelukast. METHODS After a run-in period, children 2 to 8 years old ...

This study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. The size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). Processing/formulation parameters for formation of the nanoparticles were studied to determine their effects o...

INTRODUCTION Inhaled budesonide is a novel approach to prevent acute mountain sickness (AMS). However, its mechanism is not completely understood. We aimed to investigate the effects of budesonide and dexamethasone on renin-angiotensin-aldosterone system in AMS prevention. MATERIALS AND METHODS Data were obtained from a randomised controlled trial including 138 participants. The participants ...

Symbicort SMART(R) (Symbicort Maintenance and Reliever Therapy) represents a new and unique way of treating patients with moderate-to-severe asthma, ie, those patients who require combination treatment with an inhaled corticosteroid and a long-acting inhaled beta(2)-agonist. Symbicort SMART enables patients to use only one inhaler, the budesonide-formoterol combination inhaler, for both mainten...
