Ethyl loflazepate (Lof) has been used widely as a sedative and anxiolytic agent for nearly 20 years. Ethyl loflazepate was designed to be a prodrug for descarboxyloflazepate, its active metabolite. It is the active metabolite which is responsible for most of the pharmacological effects rather than ethyl loflazepate. The main metabolites of ethyl loflazepate are descarbethoxyloflazepate, loflazepate and 3-ydroxydescarbethoxyloflazepate which are the benzodiazepine receptor agonists. Ethyl loflazeplate is commercialized in Mexico, under the trade name Victan. It is officially approved for the following conditions Anxiety: Post-trauma anxiety; Anxiety associated with severe neuropathic pain; Generalized anxiety disorder (GAD); Panic attack; Delirium tremens. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Accumulation of the active metabolites of ethyl loflazepate are not affected by those with renal failure or impairment. The symptoms of an overdose of ethyl loflazepate include sleepiness, agitation and ataxia. Hypotonia may also occur in severe cases. These symptoms occur much more frequently and severely in children. High doses of the antidepressant fluvoxamine may potentiate the adverse effects of ethyl loflazepate.
