Changes in methacholine induced bronchoconstriction with the long acting beta 2 agonist salmeterol in mild to moderate asthmatic patients.
BACKGROUND Beta-2 agonists protect against non-specific bronchoconstricting agents such as methacholine, but it has been suggested that the protection afforded by long acting beta 2 agonists wanes rapidly with regular treatment. METHODS The changes in airway responsiveness were investigated during and after eight weeks of regular treatment with salmeterol 50 micrograms twice daily in 26 adult...
متن کاملOveruse of short-acting beta-agonist bronchodilators in COPD during periods of clinical stability.
BACKGROUND Overuse of short-acting beta-agonists (SABA) is described in asthma, but little is known about overuse of SABA in chronic obstructive pulmonary disease (COPD). METHODS Prospective 3-month cohort study of patients with moderate-to-severe COPD who were provided a portable electronic inhaler sensor to monitor daily SABA use. Subjects wore a pedometer for 3 seven-day periods and were a...

متن کاملBronchodilator tolerance and rebound bronchoconstriction during regular inhaled beta-agonist treatment.
There is uncertainty about the development of airway tolerance to beta-agonists and the phenomenon of rebound bronchoconstriction on beta-agonist withdrawal. We have recently completed a study of the regular terbutaline and budesonide treatment in asthma. We report our observations on the effect of starting and stopping terbutaline treatment on morning and evening peak flows. The study was a ra...
متن کاملPrescription of oral short-acting beta 2-agonist for asthma in non-resource poor settings: A national study in Malaysia
OBJECTIVE Use of oral short-acting beta 2-agonist (SABA) persists in non-resource poor countries despite concerns for its lower efficacy and safety. Utilisation and reasons for such use is needed to support the effort to discourage the use of oral SABA in asthma. This study examined the frequency of oral short-acting Beta 2-agonist (SABA) usage in the management of asthma in primary care and de...
