Physical properties of MXE
The hydrochloride salt of methoxetamine is a white, odorless crystalline powder at room temperature. A physical description of the freebase form could not be found in the readily accessible literature.
In research examining the pharmacological profile, data suggests that methoxetamine has an affinity for the N-methyl-D-aspartate (NMDA) receptor and acts as an antagonist.
Also, it is similar to the related ketamine but it has a longer duration of action than that of ketamine.
nIn addition similarly to ketamine, methoxetamine also involves dopamine and serotonin reuptake inhibition.
No studies have been performed examining the pharmacology and mode of action of methoxetamine in humans.
Pharmacokinetics of MXE
There are no published formal animal or human studies examining the pharmacokinetic properties of MXE.
Users report the rapid onset of action (10-20 minutes) following nasal insufflation, rectal, or intravenous/intramuscular administration.
The sublingual route is reported as less effective, with oral least effective.
Peak effects are reported to occur between 1-3 hours after exposure with a further duration of between three and six hours during which after-effects are experienced.
There are a few reports of effects lasting 24 hours; the half-life for clinical effects is three hours.
