Glucagon has a bronchodilator effect by stimulating cyclic AMP production t
hrough activation of its own receptor. The purpose of this study was to det
ermine if bronchodilation can be induced by glucagon in acute asthma in chi
ldren. Twenty patients with acute asthma (mean age 9.9 +/- 2.1 years) were
treated with 1 mg of subcutaneous glucagon, and 20 patients with acute asth
ma (mean age 10.7 +/- 2.1 years) received 400 mu g of metered-dose salbutam
ol. Respiratory function tests were performed (FVC, FEV1, PEFR, FEF25-75) b
efore treatment and 30 and 120 min after treatment. The test results were c
ompared with the basal values within each group and between the two groups.
When the 30-min and 120-min posttreatment respiratory function test values
were compared with the basal values, a significant improvement was found i
n the glucagon and salbutamol groups (p < 0.05). When the 0-, 30-, and 120-
min values of the glucagon group were compared with those of the salbutamol
group, there was no significant difference (p > 0.05 for each). Subcutaneo
us glucagon treatment may be an alternative to metered-dose inhaler salbuta
mol as a bronchodilator in the treatment of acute asthma in children.
