Action
Description: Nordazepam is a long-acting benzodiazepine. It enhances the activity of GABA, a major inhibitory neurotransmitter in the brain, by binding to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites within the CNS. This results in increased neuronal membrane permeability to chloride ions, leading to hyperpolarisation (a less excitable state) and stabilisation.
Pharmacokinetics:
Absorption: Time to peak plasma concentration: 1.5 hours.
Distribution: Enters breast milk. Plasma protein binding: 97%.
Metabolism: Metabolised in the liver via hydroxylation to form oxazepam.
Excretion: Mainly via urine. Elimination half-life: Approx 65 hours.
