A box of Lorazepam Orion (Lorazepam) tablets. Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication. [14] It is used to treat anxiety (including anxiety disorders), trouble sleeping, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting.

Active metabolites are produced when a person's body metabolizes the drug into compounds that share a similar pharmacological profile to the parent compound and thus are relevant when calculating how long the pharmacological effects of a drug will last. Long-acting benzodiazepines with long-acting active metabolites, such as diazepam and ...
These long-acting metabolites are partial agonists. [6] [152] Short-acting compounds have a median half-life of 1–12 hours. They have few residual effects if taken before bedtime, rebound insomnia may occur upon discontinuation, and they might cause daytime withdrawal symptoms such as next day rebound anxiety with prolonged usage.
After the last dose has been taken, the acute phase of the withdrawal generally lasts for about two months although withdrawal symptoms, even from low-dose use, can persist for six to twelve months gradually improving over that period, [123] [68] however, clinically significant withdrawal symptoms may persist for years, although gradually ...
In a study in 1984, 20 patients having taken long-term benzodiazepines were submitted to brain CT scan examinations. Some scans appeared abnormal. The mean ventricular-brain ratio measured by planimetry was increased over mean values in an age- and sex-matched group of control subjects but was less than that in a group of alcoholics. There was ...
[13] [25] More often than not, a patient who inadvertently takes more than the prescribed dose will simply feel drowsy and fall asleep for a few hours. Benzodiazepines taken in overdose in combination with alcohol , barbiturates , opioids , tricyclic antidepressants , or sedating antipsychotics , anticonvulsants , or antihistamines are ...
If held there long enough, the drug will diffuse into the blood stream, bypassing the GI tract. This may be a preferred method to simple oral administration, because MAO is known to oxidize many drugs (especially the tryptamines such as DMT ) and because this route translates the chemical directly to the brain, where most psychoactives act.
In a study of long term diazepam use, withdrawal phenomena occurred in 5% of patients taking diazepam for less than 8 months and 43% of patients taking diazepam for more than 8 months. [17] This can lead to benzodiazepines being taken for longer than originally intended, as people continue to take the drugs over a long period of time to ...
