7-chloro-5-(2-chlorophenyl)-3-hydroxy-1,3-dihydro-1,4-benzodiazepin-2-one
Lorazepam is a benzodiazepine that primarily acts by enhancing GABA-A receptor activity. It is medically used for the treatment of anxiety disorders, sleep disturbances, and seizures. The substance possesses sedative, anxiolytic, and muscle-relaxant properties. Due to its potential for dependence, Lorazepam should only be used under medical supervision.

Receptor Profile
Der GABA-A-Rezeptor ist ein ligandengesteuerter Chloridkanal und der wichtigste inhibitorische Rezeptor im zentralen Nervensystem. Er besitzt multiple allosterische Bindungsstellen für verschiedene Substanzklassen.

Lorazepam ist ein hochpotentes Benzodiazepin und positiv-allosterischer Modulator von GABAA-Rezeptoren. Bindet an die Benzodiazepinbindungsstelle (zwischen α- und γ-Untereinheiten) und erhöht die Affinität von GABA für den Rezeptor, was den Cl⁻-Einstrom verstärkt (Hyperpolarisation). Im Gegensatz zu Diazepam: Konjugation durch direkte Glucuronidierung in der Leber (kein CYP450-Abbau) — dadurch weniger pharmakokinetische Interaktionen. Halbwertszeit 10-20h (intermediär). Kein aktiver Hauptmetabolit.

Safer Use
Depressant-risk context
This substance belongs to a context where combinations with opioids, benzodiazepines, alcohol, GHB/GBL, or other sedating substances can increase sedation, blackout, aspiration, and breathing-risk patterns. Risk Check can review warning patterns; it is not medical advice and it cannot clear a combination as safe.
The risks listed may be incomplete. Especially for research chemicals and rare substances, available data is limited.
Interaction details from the knowledge layer are still being translated.
Interaction data is based on known mechanisms. Unknown or rare interactions are possible and may be life-threatening.
