Question.3595 - Question: 1) Compare the chemical structure of amphetamine (which is the main component in all legal prescription stimulants, such as Vyvanse, Adderall, etc.) to methamphetamine on p. 151 of the text; note that the only difference is a methyl group, which allows for amphetamine to pass the blood-brain barrier faster than if it weren't methylated (i.e., methamphetamine). What are your reactions to this tiny difference in chemical structure? We have talked about dosing and frequency as being extremely important variables for determining a particular drug's action. How would these variables apply here with amphetamine/d-amphetamine and methamphetamine?
