Ephedrine is an adrenergic drug that works by stimulating alpha
-and beta receptors thus causing the release of norepinephrine.
-Alpha and beta receptors exist in the sympathetic nervous system,
-(fight or flight) and stimulation causes increased heart rate,
-bronchodilation, and vasoconstriction.

In the United States, ephedra and ephedrine are sold in health food stores under a variety of brand names. Ephedrine is widely used for weight loss, as an energy booster, and to enhance athletic perfo

Ephedrine is a naturally occuring central nervous system stimulant obtained
-from the plant _Ephedra equisetina_. It is now also produced by chemical
-synthesis, the synthetic product being mark
eted in the form of its salt,
-ephedrine sulfate; it occurs as a white crystalline powder with a bitter
-taste, soluble in water and very soluble in alcohol. Ephedrine is closely
-related in
structure to methamphetamine, although its CNS actions are much
-less potent and also longer-acting than those of the amphetamines. Its
-peripheral stimulant actions are similar to but less powe
rful than those of
-epinephrine (also called adrenaline), a hormone produced in the body by the
-adrenal glands.

mucosa, raises the blood pressure and is a cardiac stimulant. Further these compounds often cause psychological side effects such as depression, nervousness, insomnia, and rapid heart rate. When take
