...Amphetamine (amfetamine (INN)) is a psychostimulant drug that is known to produce increased wakefulness and focus in association with decreased fatigue and appetite. Amphetamine is related to drugs such as methamphetamine and dextroamphetamine, which are a group of potent drugs that act by increasing levels of dopamine and norepinephrine in the brain, inducing euphoria.Rang and Dale, Pharmacology The group includes prescription CNS drugs commonly used to treat attention-deficit hyperactivity disorder (ADHD) in children. It is also used to treat symptoms of traumatic brain injury and the daytime drowsiness symptoms of narcolepsy, Postural Orthostatic Tachycardia Syndrome and chronic fatigue syndrome. Initially, amphetamine was more popularly used to diminish the appetite and to control weight. Brand names of the drugs that contain amphetamine include Adderall, Vyvanse and Dexedrine.

Amphetamines?
Do players such as Mike
Schmidt, Willie Mays, Hank
Aaron, etc deserve to be
docked because of amphetamines
use?
Or is it not a performance
enhancer, despite evidence by
anti-doping experts such as
Gary Wadler running tests, and
coming to the conclusion that
they are?

If amphetamines make your I read that melatonin is one
of the chemicals that
amphetamines makes your brain
produce. I thought this makes
you tired, so how come you
feel so full of energy? Is it
because the neurotransmitters
responsible for the stimulant
effects greatly outweigh the
effects of melatonin?

So i to am not familiar with amphetamine-induced-melatonin production, however i can offer somewhat of a mechanistic link between the 2. So if anything, the production of melatonin which may be induced by amphetamine is definitly an indirect method. Ampethamine is classically regarded as a dopamine, noradrenaline, and even to some lesser extent serotonin uptake inhibitor "reverser", basically it cases uptake proteins to actually release neurotransmitters stores from their respective cells. Well, all of those NT's share circuitry with the hypothalamus, meaning they comunicate in sequence and regulate each other. The hypothalamus is the main regulator of melatonin production within the pineal gland. So assuming over activation by dopamine (most likely) input to cells of the hypothalamus is excitatory, or maybe even inhibitory, which then either excites or relieves inhibition exerted by the hypothalamus onto the pineal gland. So thats possibly the link, it should be noted that production of this kind is a much longer process, maybe takes hours to days? and i am not familiar with melatonin biosynthesis so whether it is stored in some sort of granule or vessicle, and released upon a different mechanism? It should be noted though that melatonin is not the only sleep factor, and may serve other regulatory roles that are not well understook as of yet? |

How long does it take for If someone takes amphetamines
on a regular basic, then stops
for a week, would it still be
in your system

Amphetamines can be detected in urine for up to about 4 days after use. Unlike some other drugs, regular use of amphetamine does not significantly increase the detection window for drug testing. Amphetamines can probably be detected in blood for about a day, but blood tests are rarely used except for therapeutic monitoring, which I am guessing is not the basis of your question. |
