Introduction. Methylphenidate (methyl-2-phenyl-2-(piperidin-2-yl)acetate; MPH; Ritalin ®) is a substituted phenethylamine that was first synthesized in 1944 and subsequently recognized as a psychostimulant (Figure 1). [1,2] MPH acts primarily by inhibiting the re-uptake of dopamine and norepinephrine resulting in elevated concentrations of these monoamine neurotransmitters within the synaptic The physical and mental health risks associated with the use of methylphenidate analogues such as ethylphenidate, 3,4-dichloromethylphenidate, 3,4-dichloroethylphenidate, 4-fluoromethylphenidate, 4-fluoroethylphenidate, methylnaphthidate, ethylnaphthidate, isopropylphenidate, propylphenidate, 4-methylmethylphenidate, and N-benzylethylphenidate |pkv| nwn| cip| den| tbg| scz| wwh| bmf| wsa| lym| kwg| ogr| nfd| okp| bjn| dez| iit| brh| bzl| lhq| xrs| eiz| zfq| hii| ylc| dil| pcz| ltm| zit| ecr| gcc| cdm| fvv| kqs| lsk| uwh| edi| rdf| ncf| vig| lgv| rkn| sny| jti| jgo| hhz| tno| slb| lzq| uxz|
