Methamphetamine is a highly lipophilic amphetamine derivative that rapidly crosses the blood-brain barrier and elicits substantially greater dopamine release than amphetamine. Repeated use is associated with neurotoxicity, stimulant psychosis, and severe dependence.

Receptor Targets
Mechanism of Action
Methamphetamin acts through the following pharmacological mechanisms:
Receptor Profile
Der Serotonintransporter (SERT/5-HTT) ist ein Natrium-abhängiger Monoamintransporter, der Serotonin aus dem synaptischen Spalt zurück in die präsynaptische Zelle transportiert. Er ist das primäre Ziel von SSRI und MDMA.
Der Noradrenalintransporter (NET) ist ein Monoamintransporter, der Noradrenalin aus dem synaptischen Spalt zurücktransportiert. Er wird von verschiedenen Stimulants und Antidepressiva beeinflusst.
Der Dopamintransporter (DAT) ist ein Natrium-abhängiger Monoamintransporter, der Dopamin aus dem synaptischen Spalt entfernt. Er ist ein zentrales Ziel von Stimulants und spielt eine Schlüsselrolle im Belohnungssystem.
Der vesikuläre Monoamintransporter 2 (VMAT2) verpackt Monoamine (Dopamin, Serotonin, Noradrenalin) aus dem Zytoplasma in synaptische Vesikel. Hemmung führt zu erhöhten zytosolischen Monoamin-Konzentrationen und verstärkter Freisetzung.
Der Trace-Amine-assoziierte Rezeptor 1 (TAAR1) ist ein Gs-gekoppelter GPCR, der durch endogene Spurenamine und exogene Amphetamine aktiviert wird. Er moduliert dopaminerge und serotonerge Neurotransmission und wird als Ziel für die Sucht- und Schizophreniebehandlung erforscht.

Risks & Harm Reduction translation in progress
English prose is being expanded. Safety-critical structured data may still be shown when available.
The risks listed may be incomplete. Especially for research chemicals and rare substances, available data is limited.
Based on substance class, receptors, mechanisms, and effect profile.

These entries are submitted by users and are not verified. They may contain subjective experiences, observations, source leads, or corrections. They do not replace scientific data and are not consumption advice.
The signal hub collects approved risk signals, experience reports and source leads by relevance.
These curated terms are linked deterministically to the structured substance profile. They do not describe frequency or strength and do not replace the monograph's claims.
