Levoamphetamine is a stimulant of the sympathetic nervous system. Its found in most amphetamine preparations, such Adderall or Benzedrine (with the exception of Dexedrine). In layman's terms, there are two different types of the molecule amphetamine, levo and dextro. Dextroamphetamine, being a central nervous system stimulant, is typically associated with the "positive" or therapeutic effects of amphetamine (mental stimulation/alertness, increased confidence, decreased drowsiness/appetite). Levoamphetamine, being a sympathetic nervous system stimulant, is mostly responsible for the adverse side effcts of amphetamine, which can become worse over a period of prolonged use, in some cases even once tolerance begins to develop.
Levoamphetamine causes sweating, racing/irregular heartbeat (tachycardia), "jumpiness" or "jitters", and cotton mouth in some users. Although levoamphetamine has not been proven to have any therapeutic potential, it is still prescribed heavily by doctors for the treatment of ADD/ADHD in the form of Adderall, which is a preparation of four amphetamine salts, two of them being pure dextroamphetamine and the others being racemic (meaning they contain about equal amounts of both dextro- and levo-amphetamine). Dexedrine and its different brand-name equivalents (dextrostat, vyvnase, etc.), are the only amphetamine-based medications that contain only pure dextroamphetamine sulfate and are generally more well-tolerated than other stimulants largely due to the absence of levoamphetamine.

I want to know if I got the levoamphetamine garbage in my adderall RX. It's a blue cap with printing M. Amphet Salts 10mg The Mfg is Global. I bought them at Walgreens. Thank you counselors?
"M. Amphet Salts" is short for "mixed amphetamine salts". You really shouldn't be bothered by the presence of levoamphetamine (L-amphetamine). Adderall is racemic amphetamine. This means that it has a mixture of the left-handed (levo-) amphetamine and the right-handed (dextro-) amphetamine molecules. While dextroamphetamine has about twice the binding affinity to dopamine and norepinephrine receptors than levoamphetamine, both molecules displace catecholamines from neural vesicles at about the same rate...and that is the primary action of amphetamine in the body.
What is the difference between amphetamine and d-amphetamine?
Amphetamine is a stimulant used to treat ADHD/ADD, narcolespy, and in some cases obesity. Amphetamine has two sides (levoamphetamine and dextroamphetamine). Dextroamphetamine exerts more mental effects than levoamphetamine.
Is there any difference between the soon-to-be-generic Adderall XR and the new Vyvanse by Shire Pharmaceuticals that would justify switching to Vyvanase given that both claim to last up to 12 hours?
Vyvanase and Adderall both exert their effect in the brain through the same active chemical (dextroamphetamine). The difference between them is that they use different mechanisms for slowing the release of active drug, and that Adderall contains levoamphetamine as well and Vyvanase does not. Having looked over the prescribing information for Vyvanase, it sounds like the time release mechanism in Vyvanase is significantly better, and therefore you should expect a smoother 12 hours of effects with fewer peaks and valleys. Vyvanase may also have fewer side-effects than Adderall due to the absence of levoamphetamine. People's bodies differ in their response to drugs, so the only way to know which drug will work better for you is to try them both. One thing that is certain, though, is that Vyvanase will be more expensive, probably by a large margin.
What is the difference between Dexedrine and Adderall?
Both Dexedrine and Adderall are amphetamine based products. Amphetamine is used from treating ADHD, narcolepsy, and in some cases extreme obesity. Dexedrine contains d-amphetamine (dextroamphetamine), while Adderall contains l-amphetamine (levoamphetamine) and d-amphetamine (dextroamphetamine). These two chemicals are both sides of the drug (d is the left, l is the right) and some find a mix of the two work better.
What is the difference between d-amphetamine and ic-amphetamine?
ic amphetamine salts are generic for Adderall IR, which contains 4 different types of amphetamine salts, racemic amphetamine aspartate monohydrate, racemic amphetamine sulfate, dextroamphetamine saccharide, and dextroamphetamine sulfate. All of these are amphetamine salts. ic amphetamine salts contain dextroamphetamine as well racemic amphetamine mixtures, which contain equal parts levo- and dextro- amphetamine. So the difference is that ic amphetamine salts (Adderall IR) contains ~75% dextoamphetamine and ~25% levoamphetamine.
What is in Adderall XR?
extended release meaning it will have a much longer affect, around 12 hours, then normal addy. it basically has one side of the pill that releases it's effects immediately and lasts for a few hours then the second half dissolves more slowly to give an extended effect.
How long will Adderall 5mg take to clear your system?
Four hours is the time to reach the peak. The dextroamphetamine has a half-life of approximately 10 hours and the levoamphetamine has a half-life of 13 hours. It will take something like 2-5 for the concentrations in your body to not appear in a standard drug test.
I take 2 30mg of Adderall daily how long does it take to leave your system?
The average elimination half-life in adults for dextroamphetamine and levoamphetamine is 10 hours and 13 hours respectively. Lets say 1/2 life = 11.5h (of course depending your body and ratio of amphetamine preparations you may possess a different half life) 2x30mg = 60mg 1/2 life = 11,5h In other words: 60mg(after 11,5h) -> 30mg(1/2 of 60mg) 60mg(after 23h) -> 15mg(1/4 of 60mg) 60mg(after 34,5h) -> 7,5mg(1/8 0f 60mg) ***** 24-72 hours depending on your metabolic rate. But if you're asking this for drug testing purposes, you should know that Adderall WILL show up in a hair follicle drug test for up to 90m days after you take it. It should be undetectable in a urine test after 72 hours. But again, that depends on your metabolic rate and how well your liver is working.
I've been treated with Dexamphetamine in Australia since i was 14 and I'm 29 currently. What i want to know is if Adderall only available in us has any added benefits that Dexamphetamine if so what?
First off, know that most molecules (drug or otherwise) exist in two forms, which can be considered akin to "right-handed" and "left-handed" versions. For most drugs, there is little if any significant difference between the two forms. When it comes to amphetamine, the right-handed version (dextroamphetamine or (d)-amp) has been associated with the "positive" side effects: increased stamina/concentration, reduced appetite, etc. The left-handed version (levoamphetamine or (l)-amp) tends to be associated with the negative side effects: agitation, withdrawal, nausea at higher doses, etc. That said, both forms act as central nervous system stimulants and their differences may not be functionally significant in all people. Dexedrine™ is strictly the right-handed isomer of amphetamine. Adderall™ is a mixture of amphetamine salts, with an overall 3:1 ratio between right- and left-handed molecules. In conclusion, you're not likely to experience any significant benefits from Adderall™.
Does d-amphetamine salt combo have maoi?
D-amphetamine salt combo is a mixture of 25% dextroamphetamine sulphate, 25% dextroamphetamine saccharate, 25% racemic amphetamine aspartate monohydrate, and 25% racemic amphetamine sulfate. To put it simply, its 75% dextroamphetamine, and 25% levoamphetamine. It's Adderall and watered down speed. It helps control symptoms of attention deficit hyperactivity disorder, like what I have. It helps me calm down and not me so "all over the place" so I can stay on one task and not be so unfocused. For people without ADHD, it can make them wired, speedy, euphoric, etc. Since it is just watered down speed.
What is the drug Adderall?
Adderall is the racemic mixture of 4 amphetamine salts. The amphetamine salts are derivatives of dextroamphetamine and levoamphetamine (2 Analogues of the Amphetamine molecule). It is a stimulant used in people with ADHD, narcolepsy, and sometimes treatment resistant depression. Adderall has a calming effect on those who have ADHD so it will allow them to focus, get their tasks completed, and manage their ADHD. In order for a person with ADHD to receive therapeutic benefits, it is generally taken at low doses. If an individual with ADHD were to take a higher dose of the drug, they would experience effects of speed. For those who do not have ADHD that so choose to take Adderall, they will have effects similar to speed, because that is what Adderall is, pharmaceutical grade speed. It's effects are euphoria, alertness, metacognition, increased confidence, compulsion to achieve some sort of task (whether it be homework, cleaning, dancing, etc.). This is why it is sometimes sought out by students who wish to improve their grades, especially during final examinations at colleges and univeristies. I used to take Adderall XR for my ADHD, but then it started making me nervous, so I was switched to Dexedrine Spansules (which is pure dextroamphetamine). As a college student, I have been approached numerous times with offers to buy my prescription. Even though the money offered for my prescription is a very nice chunk of change, I do not sell it. Instead I just deny any allegations of me having a prescription for speed or ADHD at all.
When taking Adderall will you fail youe drug test for weed?
its possible if you are only being tested for methamphetamine, though this can be solved through gc/ms testing. adderall contains a mix of amphetamine salts. the amphetamine molecule is broken down into two isomers, levo amphetamine and dextroamphetamine. Adderall is made up of about 71% dextroamphetamine, the rest is levoamphetamine. through gc/ms they can break it down and see that you have dexro and levo and not the methylated version. of course this is redundant if you don't have a legal prescription for it.AnswerThe thing about Adderall is this: It's made out of amphetamine, which is always tested for. If you're taking Adderall and you're not supposed to be, you'll get nailed for amphetamines.
