These studies examined the effects of a high-affinity anti-(+)-methamphetamine monoclonal antibody (mAb; KD = 11 nM) on (+)-methamphetamine [(+)-METH] and (+)-amphetamine [(+)-AMP] serum and tissue disposition and serum protein binding following i.v. (+)-METH administration. Male Sprague-Dawley rats were pretreated with a buffer solution (control rats) or with anti-(+)-METH mAb [equimolar in bi...

Monoamine transporters are the main targets of methamphetamine (METH). Recently, we showed that fluoxetine, a selective serotonin reuptake inhibitor (SSRI), decreased METH conditioned place preference (CPP), suggesting that serotonin transporter (SERT) inhibition reduces the rewarding effects of METH. To further test this hypothesis, in the present study we investigated the effects of additiona...

Foster care caseloads have nearly doubled over the last three decades. Parental methamphetamine (meth) use grew significantly during the same period. While child welfare workers and law enforcement claim that parental meth use contributes to foster care growth, the evidence for a causal effect has not been determined. This paper presents the first evidence of a causal effect of meth on foster c...

s | 39 Abstract Oxytocin has been proposed as a potential treatment approach in drug addiction, but little is known about the effects of oxytocin in translationally relevant models of addiction or the neurobiological substrates of the actions of oxytocin. This presentation highlights the ability of oxytocin to reduce drug taking and drug seeking in a rat model of methamphetamine (meth) addictio...

background and aims: this study examined sub-chronic effects of methamphetamine (meth) on the stereological parameters in the cornu ammonis (ca) of the hippocampus in adult mice. materials and methods: fifteen adult male mice, eight weeks old, were randomly divided into three groups: receive saline (controls), or low-dose (ld) 2.5 mg/kg meth, or high-dose (hd) 25 mg/kg meth, via daily intraperi...

Methamphetamine (METH) is a widely abused illegal psychostimulant, which is confirmed to be neurotoxic and of great damage to human. Studies on the role of brain-derived neurotrophic factor (BDNF) in human METH addicts are limited and inconsistent. The purposes of this study are to compare the serum BDNF levels between METH addicts and healthy controls during early withdrawal, and explore the c...

BACKGROUND Methamphetamine (METH) is a psychostimulant with high abuse liability that affects the monoamine neurotransmitter systems, particularly the dopamine system. Currently there are no effective medications for the treatment of METH abuse to restore METH-induced dopaminergic dysfunction. The Jitai tablet (JTT), a commercial traditional Chinese medicinal preparation, has been shown to modu...

We hypothesized that treatment of pregnant rat dams with a dual reactive monoclonal antibody (mAb4G9) against (+)-methamphetamine [METH; equilibrium dissociation rate constant (KD) = 16 nM] and (+)-amphetamine (AMP; KD = 102 nM) could confer maternal and fetal protection from brain accumulation of both drugs of abuse. To test this hypothesis, pregnant Sprague-Dawley rats (on gestational day 21)...

BACKGROUND Methamphetamine (METH) and amphetamine (AMP) concentrations in 200 plasma and 590 oral fluid specimens were used to evaluate METH pharmacokinetics and pharmacodynamics after oral administration of sustained-release METH. METHODS Eight participants received four oral 10-mg S-(+)-METH hydrochloride sustained-release tablets within 7 days. Three weeks later, five participants received...
