Ephedrine, a sympathomimetic amine, acts on part of the sympathetic nervous system (SNS). The principal mechanism of action relies on its indirect stimulation of the adrenergic receptor system by increasing the activity of norepinephrine at the postsynaptic α and β receptors.
What are the effects of ephedrine?
The most common side effects of Ephedrine include:
- spinning sensation (vertigo),
- loss of appetite,
- trouble sleeping,
What does ephedrine do in the brain?
Ephedrine, which has been used as a decongestant and weight loss agent, causes both central serotonin and dopamine (DA) release (Bowyer et al., 2000).
How does ephedrine affect blood pressure?
Ephedrine produces norepinephrine release, stimulating mostly A1 and B1 receptors; the effects resemble those of epinephrine although they are less intense. Increases in systolic blood pressure, diastolic blood pressure, heart rate, and cardiac output are noted.
What is the function of ephedrine?
What Is Ephedrine? Ephedrine is a central nervous system stimulant used to treat breathing problems (as a bronchodilator), nasal congestion (as a decongestant), low blood pressure problems (orthostatic hypotension), or myasthenia gravis.
What are the long term effects of ephedrine?
Ephedra can cause severe life-threatening or disabling conditions in some people. Ephedra use is linked to high blood pressure, heart attacks, muscle disorders, seizures, strokes, irregular heartbeat, loss of consciousness, and death.
How much weight can you lose on ephedrine?
In addition to the short-term changes in metabolism, some studies show that ephedrine can promote weight and fat loss over longer time periods. In five studies of ephedrine compared to a placebo, ephedrine led to weight loss of 3 pounds (1.3 kg) per month more than a placebo — for up to four months ( 10 , 11 ).
Does ephedrine affect sleep?
When given by injection it lasts about an hour and when taken by mouth it can last up to four hours. Common side effects include trouble sleeping, anxiety, headache, hallucinations, high blood pressure, fast heart rate, loss of appetite, and inability to urinate. Serious side effects include stroke and heart attack.
Does ephedrine deplete?
Large parenteral doses of ephedrine may cause confusion, delirium, hallucinations, or euphoria. Ephedrine may deplete norepinephrine stores in sympathetic nerve endings and tachyphylaxis to the cardiac and pressor effects of the drug may develop.
Why is ephedrine controlled?
Stringent regulation of all ephedrine products is necessary to prevent misuse and to protect the public’s health.
What medications have ephedrine?
Common brands containing ephedrine:
- Primatene® Tablets.
- Store Brands (ex: Walmart’s “Equate” store brand or CVS Health store brand)
Does ephedrine lower blood pressure?
EPHEDRINE (e FED rin) injection is used to treat low blood pressure in patients who received certain types of anesthesia, underwent a specific type of surgery, or received an overdose of a drug that can lower blood pressure.
Why do you take aspirin with ephedrine?
Aspirin. Aspirin is a pain reliever. When taken as part of an ECA stack, aspirin prevents norepinephrine levels from decreasing. In other words, its helps maintain the stimulation effects that the caffeine and ephedrine help provide.
What is ephedrine found in?
Synthetic ephedrine and pseudoephedrine are found in over-the-counter decongestants and cold medicines and are used to treat asthma. Ephedrine is not approved in the United States as a drug for weight loss or to enhance athletic performance.
Is ephedrine basic or acidic?
It has a role as a nasal decongestant, a sympathomimetic agent, a vasoconstrictor agent, a xenobiotic, an environmental contaminant, a plant metabolite and a bacterial metabolite. It is a member of phenylethanolamines and a phenethylamine alkaloid. It is a conjugate base of a (-)-ephedrinium.
Which is better ephedrine or pseudoephedrine?
Ephedrine applied to the nasal mucosa reduces nasal resistance more quickly and strongly than oral pseudoephedrine, but with shorter action time , . At end of treatment, there may be a rebound effect with increased nasal resistance and recurrence of congestion, for which several hypotheses have been suggested.
