TABLETS USP
DESCRIPTION
Hydralazine Hydrochloride Tablets USP is an antihypertensive, for oral
administration. Its chemical
name is 1-hydrazinophthalazine monohydrochloride, and its structural
formula is:
C
H
N
·HCL M.W. 196.64
Hydralazine hydrochloride, USP is a white to off-white, odorless
crystalline powder. It is soluble in
water, slightly soluble in alcohol, and very slightly soluble in
ether. It melts at about 275°C, with
decomposition.
Each tablet for oral administration contains 10 mg, 25 mg, 50 mg or
100 mg hydralazine hydrochloride,
USP. Tablets also contain anhydrous lactose, FD&C yellow no. 6
aluminum lake, microcrystalline
cellulose, sodium starch glycolate, and stearic acid.
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 production
of angiotensin II, which then causes stimulation of aldosterone and
consequent sodium reabsorption.
