Ephedrine (l-form) is an alkaloid, which was initially purified from Ephedra plant. The extract form Ephedra has been used in China for medicinal purposes for several thousand years. Ephedrine acts as an agonist at alpha- and beta-adrenergic receptors and indirectly causes the release of norepinephrine from sympathetic neurons. The drug crosses the blood brain barrier and stimulates the central nervous system. Ephedrine products are now banned in many countries, as they are a major source for the production of the addictive compound methamphetamine. FDA has approved ephedrine only for the treatment of clinically important hypotension occurring in the setting of anesthesia.

Sample Use Guides

The recommended dosages for the treatment of clinically important hypotension in the setting of anesthesia is an initial dose of 5 to 10 mg administered by intravenous bolus. Administer additional boluses as needed, not to exceed a total dosage of 50 mg.
Route of Administration: Intravenous
In Vitro Use Guide
Segments of guinea-pig ileum were treated with 10(-6)-10(-3) M ephedrine. Ephedrine inhibited the ileal responses to transmural stimulation in the terminal and the proximal ileum with EC50 values of 57.2 and 85.5 uM, respectively. In the proximal part of the ileum, more than 70% of preparations were relaxed by ephedrine.
