THERAPEUTIC CLASSIFICATION
VASODILATOR
ACTIONS AND CLINICAL PHARMACOLOGY
The principal pharmacological action of NITROJECT® (Nitroglycerin for
Injection, USP) is the
relaxation of vascular smooth muscle. Nitrates probably act primarily
by reducing oxygen
demand rather than increasing myocardial oxygen supply. Although
venous effects predominate,
nitroglycerin produces, in a dose-related manner, dilatation of both
arterial and venous beds.
Dilation of the postcapillary vessels, including large veins, promotes
peripheral pooling of blood
and
decreases
venous
return
to
the
heart,
reducing
left
ventricular
end-diastolic
pressure
(preload).
Arteriolar
relaxation
reduces
systemic
vascular
resistance
and
arterial
pressure
(afterload). Left ventricular end diastolic pressure and volume are
decreased, resulting in
reduction of ventricular wall tension results in a net decrease in
myocardial oxygen consumption
(as measured by the pressure-rate product, tension time index and
stroke work index). A
favorable net balance between myocardial oxygen supply and demand is
achieved. Elevated
central venous and pulmonary capillary wedge pressures, pulmonary
vascular resistance and
systemic vascular resistance are also reduced by nitroglycerin
therapy.
Therapeutic doses of intravenous nitroglycerin reduce systolic,
diastolic and mean arterial blood
pressure. Effective coronary perfusio
