ACTION AND CLINICAL PHARMACOLOGY
Dolasetron and its active metabolite, hydrodolasetron (MDL 74156), are
selective 5-HT
3
receptor antagonists shown not to have activity at other known
serotonin receptors and with
low affinity for dopamine receptors. The serotonin 5-HT
3
receptors are located on the nerve
terminals of the vagus in the periphery and centrally in the
chemoreceptor trigger zone of
the area postrema. It is thought that chemotherapeutic agents produce
nausea and
vomiting by releasing serotonin from the enterochromaffin cells of the
small intestine, and
that serotonin then activates the 5-HT
3
receptors located on vagal afferents to initiate the
vomiting reflex.
In healthy volunteers (N=4), dolasetron mesylate in single intravenous
doses up to 5 mg/kg
produced no effect on pupil size or meaningful changes in EEG
tracings. Results from
neuropsychiatric
tests
revealed
that
dolasetron
mesylate
does
not
alter
mood
or
concentration. Multiple daily doses of dolasetron have no effect on
colonic transit in
humans. Dolasetron has no effect on plasma prolactin concentrations.
EFFECTS ON ELECTROCARDIOGRAM
Acute, reversible, ECG changes (PR and QTc; QRS widening), caused by
dolasetron, have
been
observed
in
controlled
clinical
trials.
Dolasetron
appears
to
prolong
both
depolarization and repolarization time. The magnitude and frequency of
the ECG changes
increased with dose (related to the peak plasma concentration of
hydrodolasetron but not
the parent compound). These ECG changes usually returned to baseline
within 6 to 8
hours, but in some patients have lasted 24 h or longer. Dolasetron
