title: The effect of glucagon on airway resistance.
abstract: Nine subjects with obstructive airway disease took part in this double-blind study of the effect of glucagon in relieving bronchoconstriction compared with isoproterenol or isotonic saline. Drugs were administered via an in-line intermittent positive-pressure breathing unit. FEV1, MEF, PEF, and nitrogen washout data were evaluated. Ten minutes after administration of saline, mean FEV1 and MEF values were significantly reduced from baseline levels (P less than 0.05). Compared to saline, isoproterenol was followed by significantly increased FEV1 and MEF values (P less than 0.05) at both 10 and 30 minutes after medication, indicating reduction in bronchoconstriction. Although the 1-mg dose of glucagon was followed by a mean decrease in these parameters, this decrease was less than that seen after saline alone.
