Why Does Ativan Last For So Long?
The medication of Ativan basically interferes with the work of the central nervous system. Ativan is an anti-anxiety medicine. The chemical responsible for calming the brain (nervous system) is gamma-aminobutyric acid (GABA). During anxiety or restlessness, the brain becomes deficient in this chemical. Hence, this medicine is taken as it increases the availability of GABA to the brain which provides a calming effect to the body and mind.
Not only does Ativan act fast, but its effect also lasts for a much longer period of time. The half-life of Ativan is said to be 12 hours which means its concentration decreases in the body to half after every 12 hours.
The longevity of this medication depends on various biological factors such as height, weight, age, kidney functioning, etc. Young people are able to get this cleared in a lesser amount of time as compared to the older ones. With kidney malfunctioning, the drug may last for a longer time in the body.
Ativan is an anti-anxiety medication. This medication was developed by D.J. Richards. It was launched by Wyeth Pharmaceuticals in 1977. Other names of this mediciene are diazepam, oxazepam, bromazepam etc. Its chemical formula is C15H10Cl2N2O2.
This drug can be consumed orally in the form of pills and can be injected into the body as well. The injection rather works faster than the pills. Ativan works directly on the nervous system and is then metabolized by the liver and is then eliminated from the kidneys in the form of urine. In this way, it gets out of the body.
The medicine should be taken as prescribed by the doctor because its overdose can be dangerous and can even be fatal.
