Metoprolol tartrate USP is a selective beta -adrenoreceptor blocking
agent, available as 25, 50 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, practically odorless, 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.
The tablets contain the following inactive ingredients:
microcrystalline cellulose, corn starch, sodium
starch glycollate, colloidal silicon dioxide, sodium lauryl sulfate,
talc, magnesium stearate,

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Metoprolol tartrate 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.
