ACTION AND CLINICAL PHARMACOLOGY
Epoprostenol sodium, also known as prostacyclin, PGI
2
or PGX, a metabolite of arachidonic
acid, is a naturally occurring prostaglandin. Epoprostenol has two
major pharmacological
actions: (1) direct vasodilation of pulmonary and systemic arterial
vascular beds, and (2)
inhibition of platelet aggregation. In animals, the vasodilatory
effects of epoprostenol reduce
right and left ventricular afterload and increase cardiac output and
stroke volume. The effect of
epoprostenol on heart rate in animals varies with dose. At low doses,
there is vagally mediated
bradycardia, but at higher doses, epoprostenol causes reflex
tachycardia in response to direct
vasodilation and hypotension. No major effects on cardiac conduction
have been observed.
Additional pharmacologic effects of epoprostenol in animals include
bronchodilation, inhibition
of gastric acid secretion, and decreased gastric emptying.
PHARMACOKINETICS
ABSORPTION/DISTRIBUTION:
Epoprostenol is rapidly hydrolyzed at neutral blood pH and is also
subject to enzymatic degradation. No available chemical assay is
sufficiently sensitive and
specific to assess the
_in vivo_
human pharmacokinetics of epoprostenol. Animal studies using
tritium-labelled epoprostenol have indicated a high clearance (93
mL/min/kg), small volume of
distribution (357 mL/kg), and a short half-life (2.7 minutes). During
infusions in animals, steady-
state plasma concentrations of tritium-labelled epoprostenol were
reached within 15 minutes and
were proportional to infusion rates.
METABOLISM:
Tritium-labelled epoprostenol has been administered to humans in order
to identify
the
