Tablets Why Prescribed
To treat insomnia. How It Works
In general, estazolam produces a mild sedative effect by depressing activity in the central nervous system (the brain and spinal cord). In particular, estazolam appears to enhance the effect of gamma-aminobutyric acid (GABA), a natural chemical that inhibits the firing of neurons and dampens the transmission of nerve signals, thus decreasing nervous excitation.
