Ephedrine
Ephedrine
Ephedrine (pronounced: eh-FED-rin) is a medication and stimulant. It is often used to prevent low blood pressure during spinal anesthesia. It has also been used for asthma, narcolepsy, and obesity but is not the preferred treatment. It is of unclear benefit in nasal congestion. It can be taken by mouth or by injection into a muscle, vein, or just under the skin. Onset with intravenous use is fast, while injection into a muscle can take 20 minutes, and by mouth can take an hour for effect.
Etymology
The term "Ephedrine" is derived from Ephedra, a genus of gymnosperms in the family Ephedraceae. It is named after the plant Ephedra, from which it was first isolated in the 1880s.
