DESCRIPTION / DEFINITIONS

Ativan® (lorazepam) is a benzodiazepine. It is prescribed for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety or anxiety associated with depressive symptoms. The exact mechanism of Ativan is not known.

ABUSE

According to its label, "The use of benzodiazepines, including lorazepam, may lead to physical and psychological dependence. The risk of dependence increases with higher doses and longer term use and is further increased in patients with a history of alcoholism or drug abuse or in patients with significant personality disorders. In general, benzodiazepines should be prescribed for short periods only (e.g. 2- 4 weeks)."

ADDICTION / DEPENDENCE

HALF LIFE AND METABOLISM

The biological half life of a substance is the time it takes for a drug to lose half of its pharmacologic activity. This is significant because it affects how soon withdrawal symptoms may appear.

The half life of Ativan is between 12-18 hours.

Ativan is mainly metabolized through the P450 pathway in the liver and the enzyme primarily handling the metabolism is CYP3A4 but it is not clear how much of the metabolism is done by other enzymes.

The CYP enzymes are the major enzymes involved in drug metabolism, and since many drugs may increase or decrease the activity of various CYP isozymes, this is a major source of adverse drug interactions, since changes in CYP enzyme activity may affect the metabolism and clearance of various drugs. For example, if one drug inhibits the CYP-mediated metabolism of another drug, the second drug may accumulate within the body to toxic levels, possibly causing an overdose.
