Half-lifeWhen administered parentally, the registered half-life of lorazepam is of 14 hours. Following the administration of 1 mg of lorazepam in healthy adult male volunteers and using a multi-doses equation based on a one-compartment model, the average elimination half-life of lorazepam was estimated to be 11 hours and 8 hours for sublingual and oral doses respectively. The absorption half-life was calculated to be 55 minutes for oral doses and 15 minutes for sublingual doses.
Protein bindingReports indicate that 85% of lorazepam administered dose is protein bound.
