Doctors' Answers to "Frequently Asked Questions" - Dextroamphetamine Sulfate
Dexedrine and Methamphetamines
Answer: Dexedrine(dextroamphetamine sulfate) is a member of the class of drugs called sympathomimetic drugs. These include many different drugs with slightly different structures and a subgroup of these drugs are amphetamines. Dextroamphetamine is included in this subgroup as is methamphetamines. These are similar drugs and will produce similar effects. The metabolism is similar although differences can be detected by very specific testing. A simple drug screen will usually not detect the subtle differences between these drugs. I would refer you to Goodman and Gilmans The Pharmacological Basis of Therapeutics (editors Hardman, Molinoff, Ruddon, and Gilman). However, for something this serious you will need an expert in drug testing and a lawyer. Also, you will need to find out how specific the drug testing is. Some drug testing is very specific(and expensive) while some is directed only at large groups of drugs(less expensive). Most drug screens are of the less expensive variety.
Answer: Most people prefer time release medications for ease of administration. However, there is always the risk that a slower more controlled release will not have the same effect as ìpulseî therapy. If you feel better on the 5 mg tablets, I would convey this to your Psychiatrist. Iím sure they wonít care a great deal as long as the daily milligram dosage is similar.
