Halazepam
 

Halazepam is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is a trifluoromethyl derivative of nordazepam. While its structure may be similar to chlordiazepoxide and diazepam, it has both less toxicity and less tendency to cause paradoxical hostility and aggression than either of them. [Wikipedia]

indication

Used to relieve anxiety, nervousness, and tension associated with anxiety disorders.

mechanism of action

Benzodiazepines bind nonspecifically to benzodiazepine receptors BNZ1, which mediates sleep, and BNZ2, which affects affects muscle relaxation, anticonvulsant activity, motor coordination, and memory. As benzodiazepine receptors are thought to be coupled to gamma-aminobutyric acid-A (GABAA) receptors, this enhances the effects of GABA by increasing GABA affinity for the GABA receptor. Binding of GABA to the site opens the chloride channel, resulting in a hyperpolarized cell membrane that prevents further excitation of the cell.

biotransformation

Hepatic.
