Lorazepam is a drug used for treatinganxiety. It is in the benzodiazepine family, the same family that includesdiazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), flurazepam (Dalmane)and others. Excessive activity of nerves in the brain may cause anxiety and other psychological disorders. Gamma-aminobutyric acid (GABA) is a neurotransmitter in the brain used to send messages . GABA reduces the activity of nerves in the brain. Using Lorazepam and other benzodiazepines may enhance the effects of GABA in the brain. Because lorazepam is extracted from the blood more rapidly than many other benzodiazepines, there is less chance that lorazepam in blood will become too high and become toxic. Lorazepam also has less interactions with other kinds medications than most of the other benzodiazepines. Lorazepam has been approved by the FDA in March 1999.
