How AMBIEN Works

Zolpidem functions as a GABA A receptor positive modulator. It binds to the benzodiazepine site of GABA A receptors specifically containing the α1 subunit. This binding increases the frequency of chloride channel opening, leading to hyperpolarization of the neuron and the inhibition of neuronal excitation, which facilitates the onset of sleep.
