Ce. Reed et al., AEROSOL BECLOMETHASONE DIPROPIONATE SPRAY COMPARED WITH THEOPHYLLINE AS PRIMARY-TREATMENT FOR CHRONIC MILD-TO-MODERATE ASTHMA, Journal of allergy and clinical immunology, 101(1), 1998, pp. 14-23
Background: Inhaled corticosteroids and oral theophylline are effectiv
e treatments for moderate asthma. Objective: We sought to compare the
benefits and adverse reactions of theophylline and aerosol beclomethas
one spray. Methods: A multicenter, double-blind, double-placebo, rando
mized, controlled trial of 1-year duration was performed. Seven hundre
d forty-seven patients with asthma received either beclomethasone dipr
opionate aerosol spray (84 mu g four times per day) or sustained-relea
se theophylline twice per day in doses adjusted for optimum control of
the disease. The main outcome measures were daily diary of symptoms a
nd peak flow rates (recorded on a mark-sense computer-readable form);
supplemental bronchodilator use; doctor's office or hospital visits an
d absence from work or school; spirometry; methacholine testing; adver
se experiences; and cortisol blood measurements. Results: Both treatme
nt strategies reduced symptoms promptly and achieved low absenteeism f
rom work or school and low rates of emergency treatment for asthma. Bo
th maintained nearly normal pulmonary function. Beclomethasone was sta
tistically significantly more effective in reducing symptoms, suppleme
ntal bronchodilator and systemic glucocorticoid doses, bronchial hyper
responsiveness, and eosinophilia. However, the magnitude of these diff
erences was small. Theophylline caused more headache, nervousness, ins
omnia, and gastrointestinal distress, and more patients discontinued t
reatment because of side effects. Beclomethasone caused more oropharyn
geal candidiases and hoarseness and reduced morning plasma cortisol le
vels before and after cosyntropin. It reduced the rate of growth in ch
ildren, No new cataracts or glaucoma developed. Conclusion: Theophylli
ne effectively controlled symptoms at lower than the customarily recom
mended blood level. The risk/benefit profiles of these agents suggest
that inhaled corticosteroids may be the preferred agent for most adult
patients and for some children.
