থেরাপিউটিক ইঙ্গিত:

Lorazepam is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety or anxiety associated with depressive symptoms. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic. The effectiveness of lorazepam in long-term use, that is, more than 4 months, has not been assessed by systematic clinical studies. The physician should periodically reassess the usefulness of the drug for the individual patient. Lorazepam is contraindicated in patients with -  hypersensitivity to benzodiazepines or to any components of the formulation. -  acute narrow-angle glaucoma.

DESCRIPTION
Lorazepam, an antianxiety agent, has the chemical formula,
7-chloro-5-(o -chlorophenyl)-1,3-dihydro-3-
hydroxy-2H-1,4-benzodiazepin-2-one:
It is a nearly white powder almost insoluble in water. Each lorazepam
tablet, to be taken orally, contains
0.5 mg, 1 mg, or 2 mg of lorazepam. The inactive ingredients present
are lactose monohydrate,
magnesium stearate, microcrystalline cellulose, and sodium starch
glycolate.
CLINICAL PHARMACOLOGY
Studies in healthy volunteers show that in single high doses lorazepam
has a tranquilizing action on the
central nervous system with no appreciable effect on the respiratory
or cardiovascular systems.
Lorazepam is readily absorbed with an absolute bioavailability of 90
percent. Peak concentrations in
plasma occur approximately 2 hours following administration. The peak
plasma level of lorazepam from
a 2 mg dose is approximately 20 ng/mL.
The mean half-life of unconjugated lorazepam in human plasma is about
12 hours and for its major
metabolite, lorazepam glucuronide, about 18 hours. At clinically
relevant concentrations, lorazepam is
approximately 85% bound to plasma proteins. Lorazepam is rapidly
conjugated at its 3-hydroxy group
into lorazepam glucuronide which is then excreted in the urine.
Lorazepam glucuronide has no
demonstrable CNS activity in animals.
The plasma levels of lorazepam are proportional to the dose given.
There is no evidence of
accumulation of lorazepam on administration up to six months.
Studies comparing young and elderly subjects have shown that advancing
age does not have a significant
effect on the pharmacokinetics of lorazepam. However, in one study
involving single intravenous doses
of 1.5 to 3 mg of lorazepam injection, mean total body clearance of
lorazepam decreased by 20% in 15
elderly subjects of 60 to 84 years of age compared to that in 15
younger subjects of 19 to 38 years of
age.
INDICATIONS AND USAGE
Lorazepam is indicated for the managem
