Comparative study of acute effects of albuterol and isoproterenol sulphate aerosols in bronchial asthma. 1977

V K Mahajan, and J F Tomashefski, and G L Huber

Albuterol, a new bronchodilator drug known to cause beta2-adrenergic receptor stimulation, was compared with isoproterenol sulphate for their pulmonary and cardiovascular effects in patients suffering from bronchial asthma. In a double-blind manner 24 patients received as aerosol 170 micrograms of Albuterol or 150 micrograms of Isoproterenol or placebo on three different days. Spirometric, plethysmographic, heart rate and blood pressure measurements were made at 1, 5, 15, 30, 60, 90, 120, 300 and 360 minutes after drug inhalation. Baseline values for the various indices were not significantly different before administration of the drugs. Results demonstrate that Albuterol is an effective bronchodilator and its bronchodilating effect is significantly superior and of longer duration than that of Isoproterenol. Albuterol did not produce any significant changes in blood pressure and pulse rate, thus confirming its selectivity for beta2 receptors.
