title: A bronchodilator action of glucagon.
abstract: We evaluated the effect of glucagon on eight patients with asthma. After withholding bronchodilators for 12 hours, patients received either 2 units of intravenous glucagon or 2 ml of saline after a double-blind crossover protocol. Glucagon significantly improved the FEV1 (17.5% +/- 5.5 SEM) and the peak expiratory flow rate (14.2% +/- 4.9), compared to placebo (-2.4% +/- 2.9, p less than 0.02; 4.5% +/- 4.1, p less than 0.25, respectively). Seven patients had an excellent response to glucagon (40% to 105% of the response to inhaled isoproterenol), but four patients had no significant response. We conclude that glucagon, through its pharmacologic actions, can have a bronchodilator effect in selected patients with asthma.
