Dioxethedrin (INNTooltip International Nonproprietary Name), or dioxethedrine, also known as 3,4-dihydroxy-N-ethylnorephedrine, is a sympathomimetic medication. It was a component of the antitussive syrup Bexol (a combination of dioxethedrin, codeine, and promethazine). It is an ephedrine derivative (and hence is a phenethylamine and amphetamine) and is described as a bronchodilator and β-adrenergic receptor agonist. Analogues of dioxethedrin include dioxifedrine (α-methylepinephrine; 3,4-dihydroxyephedrine), corbadrine (levonordefrin; α-methylnorepinephrine), and α-methyldopamine.
