DESCRIPTION
Metoprolol tartrate is a selective beta
-adrenoreceptor blocking agent, available as 25 mg, 50 mg, and
100 mg tablets for oral administration. Metoprolol tartrate is
(±)-1-(isopropylamino)-3-[ _p_-2-
methoxyethyl)phenoxy]-2-propanol (2:1) _dextro_-tartrate salt. Its
structural formula is:
Metoprolol tartrate, USP is a white, crystalline powder with a
molecular weight of 684.82. It is very
soluble in water; freely soluble in methylene chloride, in chloroform,
and in alcohol; slightly soluble in
acetone; and insoluble in ether.
Each tablet for oral administration contains 25 mg, 50 mg, or 100 mg
of metoprolol tartrate and the

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Metoprolol is a beta
-selective (cardioselective) adrenergic receptor blocker. This
preferential effect
is not absolute, however, and at higher plasma concentrations,
metoprolol also inhibits beta
adrenoreceptors, chiefly located in the bronchial and vascular
musculature.
Clinical pharmacology studies have demonstrated the beta-blocking
activity of metoprolol, as shown by
(1) reduction in heart rate and cardiac output at rest and upon
exercise, (2) reduction of systolic blood
pressure upon exercise, (3) inhibition of isoproterenol-induced
tachycardia, and (4) reduction of reflex
orthostatic tachycardia.
_HYPERTENSION_
The mechanism of the antihypertensive effects of beta-blocking agents
has not been fully elucidated.
