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.

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.

PRIMARY Description: Colourless crystals or a white, crystalline powder; odourless or with a slight, aromatic odour.Solubility: Soluble in water; very soluble in ethanol (~750 g/l) TS; freely soluble in ether R.Category: Antiasthmatic drug.Storage: Ephedrine should be kept in a well-closed container, protected from light.Labelling: The designation on the container should state whether the substance is the hemihydrate or is in the anhydrous form.Additional information. Solutions of Ephedrine in chloroform R may become turbid, especially when the substance contains morethan 10 mg of water per g. Even in the absence of light, Ephedrine is gradually degraded on exposure to a humid atmosphere,the decomposition being faster at higher temperatures. Anhydrous Ephedrine melts at about 38?C, whereas Ephedrinehemihydrate melts at about 42?C.
