Ephedrine HCl is a sympathomimetic amine that has been historically and scientifically validated as a bronchodilator and decongestant. The use of ephedrine for bronchial congestion stems from its ability to stimulate adrenergic receptors, leading to relaxation of bronchial smooth muscle and constriction of nasal mucosal blood vessels. This results in decreased airway resistance and improved airflow, which can alleviate symptoms of congestion, particularly in conditions such as asthma and bronchitis.

Ephedrine was first isolated from the plant Ephedra sinica and became a mainstay in asthma and bronchitis management prior to the widespread use of selective beta-2 agonists. Numerous clinical studies and decades of therapeutic use support its efficacy as a bronchodilator and decongestant. Its mechanism of action has been well-characterized: it acts both directly on alpha and beta adrenergic receptors and indirectly by promoting the release of norepinephrine.

However, due to adverse cardiovascular effects and the development of safer alternatives (such as pseudoephedrine for nasal congestion and beta-2 agonists for bronchospasm), the use of ephedrine has declined in modern practice. Still, its role in treating bronchial congestion is supported by substantial scientific evidence, and it remains an ingredient in some prescription and over-the-counter decongestant formulations in certain countries.
