Whether IV Ī² 2-agonists improve bronchodilator response when administered in addition to nebulae bronchodilators was only addressed in three studies 20 under review. In general pure beta-adrenergic agonists have the opposite function of beta blockers. ENDPOINT--Change in peak expiratory flow rate over 4 hours.

There was no difference in heart rate 45 bpm. Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways causing widening of the airways and resulting in easier breathing. In the included RCTs there was no consistent evidence favouring either IV beta2-agonists or IV aminophylline for patients with acute asthma.
Overall selective IV beta2-agonist use conferred no advantage over the comparator regimes. Epinephrine acts on both alpha- and beta. Camargo Jr Andrew H.
MEASUREMENTS and MAIN RESULTS--Peak expiratory flow rate improved more in. Both drugs can be given intravenously. Inhaled and IV beta-agonists can contribute to lactic acidosis.
