Etafedrine
Etafedrine (pronounced: eh-tuh-fed-rin) is a pharmaceutical drug used primarily in the treatment of asthma and bronchitis. It is a bronchodilator and a vasodilator, meaning it widens the bronchi and blood vessels, respectively, to allow for easier airflow and blood flow.
Etymology
The term "Etafedrine" is derived from the Greek word "eta," meaning "seven," and "fedrine," a common suffix in the names of many pharmaceutical drugs. The "seven" in the name refers to the seven carbon atoms in the chemical structure of the drug.
Pharmacology
Etafedrine works by stimulating the adrenergic receptor, specifically the beta-2 adrenergic receptor. This stimulation causes the muscles lining the bronchi and blood vessels to relax, thereby widening these passages and allowing for easier airflow and blood flow.
