What is the difference between methylphenidate(Ritalin) and methamphetamine they are very close sounding and?

Question

are both stimulants......so is cocaine...what is the difference beside the obvious one is legal (if you have a real prescription)and one illegal. Then compared to cocaine which i have heard they actually use as a pain antestetic(sp) numbing for broken nose and having to rebreak a nose, to fix it. As weell as resetting (rebreaking) a bone that has started to heal wrong. Always wondered and never knew who to ask so i ask Yahoo Answers charming individuals.

Answer 1

The means by which methylphenidate helps people with ADHD are not well understood. Some researchers have theorized that ADHD is caused by a dopamine imbalance in the brains of those affected. MPH is a dopamine reuptake inhibitor, which means that it increases the level of the dopamine neurotransmitter in the brain by partially blocking the transporters that remove it from the synapses.
----------------------------------------------------
Methamphetamine causes the norepinephrine and dopamine transporters to reverse their direction of flow. This inversion leads to a release of these transmitters from the vesicles to the cytoplasm and from the cytoplasm to the synapse, causing increased stimulation of post-synaptic receptors.

--------------------
If you did not understand that above, I will summarize the difference:

* Methylphenidate increases the dopamine levels which are being blocked by the transporters - since it's not being allowed to the synapse as needed.

* Methamphetamine doesn't block the transporter, but instead reverses the path of the chemical dopamine back to the synapse which in turn stimulates the brain to produce more of that chemical (somehow lol).

They are similar, but work in different ways - as explained above.

Oh - and actually .. both are legal in prescribed medication form. Methylphenidate usually is known as Ritalin and Methamphetamine usually prescribed is known as Desoxyn. Both can treat ADHD and narcolepsy. It just happens that both are very commonly also turned into street drugs, and meth is often made from psuedophedrine and common house hold cleaning chemicals where as Ritalin is usually snorted for a quick hit.

Noise is unoriginality, or music attempted without soul. Sound can seem like noise in that it is not always beautiful, but it is original, and it is something with soul behind it, something real, something that can be acknowledged as familiar because it picks up on everyday subtleties. A real musician hears music in the beat of a train on tracks, the breeze flowing through leaves, horns and long-distance shouts and garbage can lids hitting the ground, the silence. There is a pulsation in every inch of life that creates a lyric and a note, and if someone can capture that, or even understand it, then they know what sound is.
