Methamphetamine use among adolescents is a significant social and public health concern.

BACKGROUND Methamphetamine is a major drug of abuse with no effective pharmacotherapy available. Trace amine associated receptor 1 is implicated in cocaine addiction and represents a potential therapeutic target. However, the effects of trace amine associated receptor 1 agonists on addiction-related behavioral effects of methamphetamine are unknown. METHODS This study examined the effects of ...

Cytochrome P450 3A4 (CYP3A4) is the major drug metabolic enzyme, and is involved in the metabolism of antiretroviral drugs, especially protease inhibitors (PIs). This study was undertaken to examine the effect of methamphetamine on the binding and metabolism of PIs with CYP3A4. We showed that methamphetamine exhibits a type I spectral change upon binding to CYP3A4 with δAmax and KD of 0.016±0.0...
