Metabolism: Lorazepam is extensively bound to plasma proteins and metabolized in the liver, in which about 95% of orally administered lorazepam is excreted in the urine and feces within 5 days. Three main metabolites are generally formed 4 h after administration of lorazepam including the lorazepam-glucuronide.

Ser det står opp til 9 dager noen steder.

Er det lab test eller hurtigprøve? For det er en del info om at lorazepam ikke alltid slår ut på slike tester, har selv opplevd dette med clonazepam på en hurtigprøve.
«Common benzodiazepines, such as clonazepam and lorazepam often result in false negatives (e.g., the patient is actually taking the substance, but the test results as negative). The immunoassay often uses an antibody to oxazepam, a metabolite of diazepam and chlordiazepoxide.»
Vet ikke hvilken prøve en immunoassay er, men det tyder jo på at både clonazepam og lorazepam er litt annerledes enn de andre benzoene.
