I don't understand. Some sites classify ritalin as an amphetamine. I always thought it was an analog of cocaine which isn't really considered an amphetmaine.
When comparing the chemical structure however, ritalin resembles amphetamine more than it does cocaine.
Input?

my pdoc says its a reuptake inhibitor and not a releaser like amphetamines. I don´t know if thats entirely true or if it releases a little some suggest it does.

Technically, no. Ritalin may be a psychostimulant, like amphetamine, but it is not an amphetamine.

'stimulant' isn't a concrete term, and since its a drug with positive effects there is lots of politics in the word. see also 'narcotic' which has a legal classification that includes drugs that have nothing to do with teh orignal meaning (opioids).
methylphenidate does not release catecholamines, but does block reuptake. it is not chemically an amphetamine (a structural word, Alpha Methyl PHenyl EThylAMINE), unlike drugs like MDMA. it is not structurally like cocaine either, though that is probably the most similar drug, though cocaine has more serotonergic effect i think.

Ritalin is chemically related to amphetamines but produces less CNS arousal than mental stimulation, a cup of coffee raises BP more than Ritalin.The PDR says "Ritalin restores mental and physical activities to normal or near normal levels.......induces alertness a brighter mental outlook and improved psychomotor performance-a specific recommendation for CF and apathy" it was also suggested for use in helping people recover from general anaesthesia-when it was available in parenteral form.
Called a 'mild stimulant' Ritalin is known to be just as good as Dexedrine. Comparison tests of both show Ritalin to be superior MG for MG in it's ability to excite mental faculties.
It is NOT technically an amphetamine but shares a similar backbone. It's mode of action shows it is closer to Cocaine than amphet.
Ritalin:-Psychostimulant
-DA reuptake inhibitor
-NE reuptake inhibitor
-NE release
Cocaine Hcl:-Psychostimulant
-DA reuptake inhibitor
-NE reuptake inhibitor
-NE release
D-amphetamine:-Psychostimulant
-DA release ++
-NE release +++
-DA reuptake inhibitor+
-NE reuptake inhibitor+

Yeah, cocaine has effects on the serotonin reuptake pump which ritalin does not.
Also, I read that ritalin does increase the release of monoamines, but just not to the extent that ampetamine does.

Don't amphetamines also *reverse* the dopamine transporter as opposed to just inhibiting it?

cocaine should include serotonin reuptake inhibition.
I never heard that ritalin definetely releases NE.

Acording to the DSM psychiatric drug charts drug MOA, which i have print outs of-it does, thou nothing comparable to Dex/meth/amphetamine, when i had a short term trial of (Dex) and which i noticed a considerable HR increase from, even after years of varying doses of MPD.
