CLINICAL PHARMACOLOGY
Although the precise mechanism of action of hydrALAZINE is not fully
understood, the major effects
are on the cardiovascular system. HydrALAZINE apparently lowers blood
pressure by exerting a
peripheral vasodilating effect through a direct relaxation of vascular
smooth muscle. HydrALAZINE,
by altering cellular calcium metabolism, interferes with the calcium
movements within the vascular
smooth muscle that are responsible for initiating or maintaining the
contractile state.
The peripheral vasodilating effect of hydrALAZINE results in decreased
arterial blood pressure
(diastolic more than systolic); decreased peripheral vascular
resistance; and an increased heart rate,
stroke volume, and cardiac output. The preferential dilatation of
arterioles, as compared to veins,
minimizes postural hypotension and promotes the increase in cardiac
output. HydrALAZINE usually
increases renin activity in plasma, presumably as a result of
increased secretion of renin by the renal
juxtaglomerular cells in response to reflex sympathetic discharge.
This increase in renin activity leads
to the pr
