DESCRIPTION
Labetalol hydrochloride (HCl) is an adrenergic receptor blocking agent
that has both selective alpha
-
adrenergic and nonselective beta-adrenergic receptor blocking actions
in a single substance.
Labetalol HCl is a racemate chemically designated as
2-hydroxy-5-[1-hydroxy-2-[(1-methyl-3-
phenylpropyl)amino]ethyl]benzamide monohydrochloride, and it has the
following structure:
Labetalol HCl has the empirical formula C
H
N
O
•HCl and a molecular weight of 364.9. It has
two asymmetric centers and therefore exists as a molecular complex of
two diastereoisomeric pairs.
Dilevalol, the R,R’ stereoisomer, makes up 25% of racemic labetalol.
Labetalol HCl is a white or off-white crystalline powder, soluble in
water.
Labetalol Hydrochloride Tablets, USP for oral administration contain
100 mg, 200 mg, or 300 mg of
labetalol HCl. Each tablet also contains the following inactive
ingredients: anhydrous lactose, colloidal
silicon dioxide, crospovidone, hydroxypropyl methylcellulose,
magnesium stearate, microcrystalline
cellulose, polyethylene glycol, polysorbate 80, pregelatinized starch,
purified water, and titanium
dioxide. Labetalol HCl Tablets, USP 100 mg also contain synthetic red

CLINICAL PHARMACOLOGY
Labetalol HCl combines both selective, competitive, alpha
-adrenergic blocking and nonselective,
competitive, beta-adrenergic blocking activity in a single substance.
In man, the ratios of alpha- to beta-
blockade have been estimated to be approximately 1:3 and 1:7 following
oral and intravenous (IV)
administration, respectively. Beta
-agonist activity has been demonstrated in animals with minimal beta
-agonist (ISA) activity detected. In animals, at doses greater than
those required for alpha-or beta-
adrenerg
