Prolonged use of inhaled corticosteroids for asthma treatment

Inhaled steroids were prescribed to 25% (n = 352) of the cohort with use steadily increasing during the first two months of hospitalization. The most frequently prescribed steroid was beclomethasone (n = 194, 14%), followed by budesonide (n = 125, 9%), and then fluticasone (n = 90, 6%). Birth gestation <24 weeks, birth weight 500-999 grams, and prolonged ventilation all increased the adjusted odds of ever receiving inhaled corticosteroids (p<). Wide variations between hospitals in the frequency of infants ever receiving inhaled steroids (range: 0-60%) and the specific drug prescribed were noted. This variation persisted, even after controlling for observed confounders.

Glycopyrrolate, a quaternary ammonium anticholinergic compound is a potentially useful bronchodilator. To determine the efficacy, optimal dose, and duration of action of inhaled glycopyrrolate, we gave the drug to 11 asthmatic patients. Each subject received placebo or glycopyrrolate (100, 200, 600, or 1,200 micrograms) by inhalation in a double-blind, randomized, crossover design. Measurements included FEV1, FVC, heart rate, and blood pressure before administration of the drug and periodically for 12 hours. For eight hours following all doses of glycopyrrolate, both FEV1 and FVC (both as percent of predicted) were significantly greater for drug than for placebo. Glycopyrrolate may be a useful long-acting drug for the treatment of asthma.
