BACKGROUND Inhalational insulin was withdrawn from market in 2007 due to its potential to produce airway hyper-reactivity and bronchoconstriction. So we explored the possible mechanism underlying the acute contractile effects of insulin and protective effects of beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pig in vitro. METHOD...

A highly sensitive, specific and rapid LC–ESI-MS/MS method has been developed and validated for simultaneous quantification of Salbutamol and Beclomethasone in human plasma (200 μl) using Anastrozole respectively, as an internal standard (IS) as per the regulatory guidelines. Results: The LLE method was used to extract the analytes and IS from human plasma. The chromatographic resolution of Sal...

In the present study, we examined whether there is a difference in the onset of bronchodilatation between formoterol/beclomethasone 12/200 μg Modulite and formoterol/budesonide 9/320 μg Turbuhaler in patients with COPD. We enrolled 28 patients with stable COPD. Both formoterol/beclomethasone and formoterol/budesonide elicited a larger mean FEV₁-AUC₀₋₁₅min than formoterol alone, whereas there wa...

BACKGROUND Fluticasone propionate is a new inhaled corticosteroid with a 2:1 efficacy ratio compared with beclomethasone dipropionate with regard to lung function and symptom scores, without increased systemic activity. The aim of this study was to investigate whether this was also the case for bronchial hyperresponsiveness, assessed by both a direct (histamine) and an indirect (ultrasonically ...

BACKGROUND Characteristics of inhaled corticosteroids (ICSs) differ, but data comparing the real-life effectiveness of various ICSs for asthma are lacking. OBJECTIVE We sought to compare real-life asthma outcomes and costs of extrafine hydrofluoroalkane (HFA)-beclomethasone and fluticasone administered through a pressurized metered-dose inhaler. METHODS This retrospective matched cohort stu...

We wanted to compare the efficacy and safety of fluticasone propionate, a new topically active inhaled corticosteroid, to that of high dose beclomethasone dipropionate, in severe adult asthma. Patients currently receiving between 1.5-2.0 mg.day-1 of an inhaled corticosteroid were treated for six weeks in a double-blind, randomized, parallel group study with 1 mg.day-1 fluticasone propionate (n ...

inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. so the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

AIMS To test the hypothesis that inhaled salbutamol or beclomethasone will reduce the frequency of cough in children with recurrent cough. A secondary aim was to determine if the presence of airway hyperresponsiveness (AHR) can predict the response. DESIGN Randomised, double blind, placebo controlled trial. METHODS During a coughing phase, 43 children (age 6-17 years) with recurrent cough w...

Inhaled glucocorticoids such as beclomethasone dipropionate, which are used in the treatment of asthma, may be associated with systemic adverse effects. To determine whether any systemic absorption following the inhalation of beclomethasone was a result of drug being absorbed from the lung (inhaled fraction) or the gastrointestinal tract (swallowed fraction), we studied normal subjects after th...
