This product is a benzodiazepine hypnotic sedative and anxiolytic. The drug acts on the benzodiazepine receptor (BZR) of the central nervous system, strengthens the binding of the central inhibitory neurotransmitter -aminobutyric acid (GABA) and the GABA receptor, promotes the opening of chlorine channels, and hyperpolarizes cells Enhances synaptic inhibition mediated by GABAergic neurons and reduces neuronal excitability. BZR receptors are divided into type I and type II. It is believed that type I receptor excitement can explain the anxiolytic effects of BZ drugs, and type II receptors are related to the sedative and skeletal muscle relaxation effects of these drugs. Can cause inhibition of different parts of the central nervous system. With the increase of dosage, clinical manifestations can range from mild sedation to hypnosis and even coma.
