An analog of Lorazepam (L469850). Sedative, hypnotic.
Controlled substance (depressant). | [Definition]
ChEBI: Lormetazepam is a 1,4-benzodiazepinone compound having a methyl substituent at the 1-position, a hydroxy substituent at the 3-position, a 2-chlorophenyl group at the 5-position and a chloro substituent at the 7-position. It has a role as a sedative. It is a 1,4-benzodiazepinone and an organochlorine compound. | [Manufacturing Process]
To a suspension of 3.4 g of 3-acetoxy-7-chloro-1,3-dihydro-5-(ochlorophenyl)-2H-1,4-benzodiazepin-2-one in 80 ml of alcohol was added 6 ml of 4 N sodium hydroxide. After complete solution had taken place a solid precipitated that redissolved upon the addition of 80 ml of water. The solution was acidified with acetic acid to give white crystals. After recrystallization from alcohol the compound melted at 192°C to 194°C. | [Therapeutic Function]

#N/A | [Drug interactions]
Potentially hazardous interactions with other drugs
Antibacterials: metabolism possibly increased by
rifampicin.
Antipsychotics: increased sedative effects; risk of
serious adverse effects in combination with clozapine.
Antivirals: concentration possibly increased by
ritonavir.
Disulfiram: metabolism inhibited, increased sedative
effects.
Sodium oxybate: enhanced effect - avoid. | [Metabolism]
Lormetazepam is metabolised in the liver to the inactive
glucuronide, and excreted in the urine. |
