PHARMACODYNAMIC AND PHARMACOKINETIC PROPERTIES
•
PHARMACODYNAMICS
Pharmacologically,
zolpidem
binds
selectively
to
the
omega-1
subclass
(or
BZ1)
of
benzodiazepine receptors in the brain without binding to peripheral
benzodiazepine
receptors. This has been corroborated by the observation that zolpidem
has little or no
muscle relaxant properties.
Zolpidem has been shown to reduce sleep latency (time to fall asleep),
decrease the
number
of
awakenings, and
to
increase total
sleep
time.
While
REM
sleep
is
not
significantly decreased, the onset of REM is delayed. The REM/non-REM
ratio is not
significantly altered. Slow wave (stages 3 and 4) sleep time is
increased. This more
closely resembles natural sleep than does hypnosis induced by the
benzodiazepines; this
may result in fewer adverse reactions related to disturbance of normal
sleep patterns.

PHARMACOKINETICS
_Absorption_
Zolpidem is rapidly absorbed from the gastrointestinal tract after
oral doses, peak
plasma concentrations occurring within 3 hours. Oral bioavailability
is 70%.
_Effect of food_: decreased systemic exposure (decreased C
max
and AUC; increased T
max
).
_Distribution_
Zolpidem is about 92% bound to plasma proteins. The distribution
volume in adults is
0.54L/kg Zolpidem is distribu
