Ritalin

Methylin stays in your system for 15 to 24-hours. This medication may cause side effects, such as nausea, headache, nervousness and insomnia.

No, its kind of like a dietary supplement, most likely if you eat right before you take any sort of generic brand of addy, you wont eat much of anything for the rest of the day, especially if you are focus on something like studying

Chemically, I don't know. That's what I was hoping to find. I know that if I don't take it, I know it. That day. As it has been explained to me, it lasts for the prescribed time, then is gone. That's why it's a daily dose. I take 60 mg a day. I would prefer 50 but they don't make a 50 mg dose. Nor do they make a 60 mg but I take (2) 30 mg at a time. The long acting (LA) version since my days are typically longer than 12 hours, which is the prescribed effective time. I have found that sleep deprivation, a common occurence for me, will shorten the effective time.

They are both Amphetamines and will show up as such on a drug test. They cannot distinguish what type of Amphetamine you took at an earlier date, only that Amphetamines were in your system. Most drug tests will not pick up on this drug after about 3 to 4 days later, but a hair test will! So I'd use a Hair Follicle Shampoo! Good Luck

No, since it is prescribed for various conditions it does not show up unless specifically tested for.

450000 billion years it will take to leave your body if u want it to go faster you need to have butt sex

i am sure that if u tack ritalin one time that you would be fine to tack a drug test in two days. they say on some 24 hours but if you do not have much in you system it would be gone faster.

Off kids with ADD/ADHD, a 20 mg goes for a dollar. Anyone charging any more is a dishonest dealer.

I don't think ritalin affects urine. I take ritalin for ADHD aand i'm pretty sure it has to relationship with pee.

1-2days

Acoording to: http://www.ipassedmydrugtest.com/drug_detection_times.asp Ritalin (Methylphenidate) is 1-2 days.

RITALIN (methylphenidate), works on the central-nervous-system in your body, as a mild stimulant. There are many uses for it, including helping people who have narcolepsy (falling asleep at inappropriate times), treats hiccups after anesthesia, treats ADHD, stroke recovery, among other things. It has a potential to be abused and become addictive. Continued abuse can cause people to have psychotic episodes. I'm sorry but the above Answer does not accurately or unbiasly depict the drug or explain or answer the question that was asked. To Answer the question, Ritalin works to increase certain nuero transmitters, specifically "Therapeutic Doses of Oral Methylphenidate Significantly Increase Extracellular Dopamine in the Human Brain".1 Dopamine is responsible for learning by increasing the "reward" response which basically tells the brain to "encode" information it learns by providing a "teaching signal" which tells the brain to "remember things" because it is good to do so. Dopamine dysfunction is responsible for decline in mental functions, such as memory, attention, and problem-solving. Ritalin Also increases Seratonin slightly "Serotonin and the Therapeutic Effects of Ritalin".2 1. http://www.jneurosci.org/cgi/reprint/21/2/RC121.pdf 2. http://www.sciencemag.org/cgi/content/full/288/5463/11a?ck=nck hope this helps :)

Absolutely....while there's not really any tests to say so, I see no reason why not, and have done so many times. Theanine is great for smoothing out the sometimes rough edges of Ritalin, as well as making for a more cozy and comfortable landing when the Ritalin wears off.

It is always important that there is good communication between your physicians. Talk to them and let them decide what treatment is appropriate. I'd say it's especially important in this case as both supplemental thyroid hormone and add stims can affect your heart.

Though the mechanism of action of cocaine is not fully understood, it is thought to bind to and block the dopamine transporter protein (DAT). Blocking the action of this protein increases the concentration of dopamine in the synaptic cleft, thereby producing the characteristic effects of cocaine (such as stimulation and euphoria). Cocaine also affects serotonin receptors, sigma receptors, and sodium channels, though these actions play less of a role in its pharmacology.

If you snort a pill it only stays in you system for about 1-2 days. But you better be ready for your nose to fell like you just inhale a fire ball......

Answer: Ritalin is an effective drug for treating ADHD because it releases an chemical in the brain called dopamine which helps to improve the concentration levels and attention of the person who is taking the drug, so yes it is an effective drug for treating ADHD.

i have both methylin er and methylnphenidate sr both 20 mg. there the same thing prity sher but i just snorted tyhe second one and it just works faster and gives you a rush faster than swolowing it

Ritalin (Methylphenidate), affects the synapse in a way that is similar to amphetamines, however in a more mild manner. It is an agonist to Dopamine and Norepenephrine; neurotransmitters in our brain that regulate arousal and attention. Normally, the transmitter fires the chemical into the synapse. the next transmitter accepts the chemical, sends the signal on, and the chemicals are recycled back into the sending transmitter; a process called "re-uptake". What Ritalin does is it blocks the re-uptake of the neurotransmitter, so more stays in the synapse, therefore creating a stronger signal throughout the brain. When these two neurotransmitters are affected in this way, it causes a feeling of arousal because of the dopamine excess, and mental clarity and focus, because of the noropenephrine excess.

yes. i have seen it happen
