A member asked:
Before albuterol what were the most commonly used bronchodilators?
A doctor has provided 1 answer
Racemic epinephrine: Once upon a time (1980) albuterol was called a long-acting bronchodilator because its effects lasted for up to 6 hours. Earlier drugs were not as good. Alupent (metaproterenol) last 3-4 hours, isoetherane 1 hour, Epinephrine 20 minutes. Theophylline, an oral bronchodilator, lasted 1-2 hours in non time-release tablets. These other drugs caused tremor, arrhythmias, and stomach upset. Albuterol was a great advance.
