ADHD Medications
ADHD medications work to effect the chemistry of the body by blocking dopamine receptors so there is more circulating in the body and reinforcing important neural circuits in the brain. For this reason these medications fall into the category of stimulant drugs. because they excite the brain and Central Nervous System. As a result a person may feel more awake, have an elevated mood, and a decrease in appetite.
Two types of molecules are used to achieve this; amphetamine, which is the stimulant component in Adderall, and methylphenidate, which is the active component in Ritalin and Concerta.
