how any one individual will respond to various doses or types of Attention Deficit Disorder medication. However, the drug of choice for Attention Deficit Disorder is Ritilan. Ritilan (Methylphenidate) is a mild CNS stimulant. In medicine, Ritilan's primary use is treatment of Attention Deficit /Hyperactive Disorder (ADHD). The reason why this drug works so well is not completely understood, but Ritilan presumably activates the arousal system of the brain stem and the cortex to produce its stimulant effect. According to the Drug Enforcement Agency (DEA), prescriptions for Ritilan have increased more than 600% in the past five years. Ritilan (Methylphenidate) is manufactured by CIBA-Geigy Corporation. It is supplied in 5 mg., 10 mg., and 20 mg. tablets, and in a sustained release form, Ritilan SR, in 20 mg. tablets. It is readily water soluble and is intended for oral use. It is a Schedule II Controlled Substance under both the Federal and Vermont Controlled Substance Acts (Bailey 1995). As stated before, ADHD is a condition most likely based in an inefficiency and inadequacy of Dopamine and Norepinephrine hormone availability, typically occurring when a person with ADHD tries to concentrate. Ritilan improves the efficiency of the hormones Dopamine and Norepinephrine, increasing the resources for memory, focus, concentration and attention (Clark 1996). Ritilan exhibits pharmacological activity similar to that of amphetamines. Ritilan's exact mechanism of action in the CNS is not fully understood, but the primary sites of activity appear to be in the cerebral cortex and the subcortical structures including the thalamus. Ritilan blocks the re-uptake mechanism present in dopaminergic neurons. As a result, sympathomimetic activity in the central nervous system and in the peripheral nervous system increases. Ritilan-induced CNS stimulation produces a decreased sense of fatigue, an increase in motor activity and mental alertness, mil...
