DL-Methamphetamine (also known as +/- Methamphetamin) is a central nervous system stimulant and sympathomimetic with actions and uses similar to DEXTROAMPHETAMINE. The smokable form is a drug of abuse and is referred to as crank, crystal, crystal meth, ice, and speed. Methamphetamine is a mixture of two isomers. One isomer called Dextro, or D Methamphetamine, is active as a central nervous system stimulant and it is a DEA Schedule 2 controlled drug commonly called “Meth” or “Speed”. Desoxyn, a prescription drug also contains D Methamphetamine. The other isomer, Levo, or L Methamphetamine is not a DEA controlled drug. It is found in an over the counter medicine called “Vicks Inhaler” or as the prescription drug, Selegiline. (+)-methamphetamine is the more physiologically active isomer. In addition to some medications, L Methamphetamine can be produced in the illegal production of street Methamphetamine.

Sample Use Guides

In Vivo Use Guide

Attention Deficit Disorder with Hyperactivity: For treatment of children 6 years or older with a behavioral syndrome characterized by moderate to severe distractibility, short attention span, hyperactivity, emotional lability and impulsivity: an initial dose of 5 mg DESOXYN once or twice a day is recommended. Daily dosage may be raised in increments of 5 mg at weekly intervals until an optimum clinical response is achieved. The usual effective dose is 20 to 25 mg daily. The total daily dose may be given in two divided doses daily. Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy. For Obesity: One 5 mg tablet should be taken one-half hour before each meal. Treatment should not exceed a few weeks in duration. Methamphetamine is not recommended for use as an anorectic agent in children under 12 years of age.

Route of Administration: Oral

In Vitro Use Guide

It was investigated whether the psychostimulant methamphetamine (METH) has a cytotoxic effect on oligodendrocytes and which cell-death pathways are involved in the cytotoxic process. METH caused concentration- and time-dependent cytotoxicity in rat oligodendrocyte cultures. METH induced apoptotic cell death and mRNA expression of pro-apoptotic proteins (bax and DP5), but not anti-apoptotic proteins (bcl-2 and bcl-XL). These results suggest that METH induces cytotoxicity in rat oligodendrocytes via the differential regulation of the expression of genes involved in the apoptotic process.
