The active ingredient in Ativan is lorazepam [1]. Lorazepam is a benzodiazepine medication used to treat anxiety disorders, insomnia, and seizures [2]. It works by enhancing the effect of a neurotransmitter called GABA, which has a calming effect on the brain [3].
What other ingredients are in Ativan?
Besides the active ingredient lorazepam, Ativan tablets contain inactive ingredients that help form the tablet and ensure its stability [1]. These may include:
* Lactose monohydrate [1]
* Microcrystalline cellulose [1]
* Polysorbate 80 [1]
* Sodium starch glycolate [1]
* Magnesium stearate [1]
* Hypromellose [1]
* Titanium dioxide [1]
* Polyethylene glycol [1]
The specific inactive ingredients can vary slightly depending on the manufacturer and dosage form.
How does lorazepam work in the body?
Lorazepam functions by increasing the activity of gamma-aminobutyric acid (GABA) in the brain [3]. GABA is an inhibitory neurotransmitter, meaning it reduces nerve activity [3]. By amplifying GABA's effects, lorazepam leads to a general calming and sedative effect [3]. This mechanism is responsible for its therapeutic effects in conditions like anxiety and insomnia [2].
When does the patent for Ativan expire?
The original patent for lorazepam expired many years ago, allowing for the production of generic versions of the medication [4]. DrugPatentWatch.com tracks patent information for pharmaceuticals; details on lorazepam patents can be found on their site [4].
