CLARITHROMYCIN TABLETS, USP
RX ONLY
To reduce the development of drug-resistant bacteria and maintain the
effectiveness of clarithromycin
and other antibacterial drugs, clarithromycin tablets should be used
only to treat or prevent infections
that are proven or strongly suspected to be caused by bacteria.
DESCRIPTION
Clarithromycin is a semi-synthetic macrolide antibiotic. Chemically,
it is 6-_0_-methylerythromycin. The
molecular formula is C
H NO , and the molecular weight is 747.96. The structural formula is:
Clarithromycin is a white to off-white crystalline powder. It is
soluble in acetone, slightly soluble in
methanol, ethanol, and acetonitrile, and practically insoluble in
water.
Clarithromycin Tablets, USP are available as immediate-release
tablets.
Each tablet for oral administration contains 500 mg of clarithromycin
and the following inactive
ingredients: croscarmellose sodium, lactose monohydrate, magnesium
stearate, microcrystalline
cellulose, Opadry II (White), povidone, stearic acid, and talc. Opadry
II (White) contains hypromellose,
polyethylene glycol, polydextrose, titanium dioxide and triacetin.
CLINICAL PHARMACOLOGY
PHARMACOKINETICS
Clarithromycin is rapidly absorbed from the gastrointestinal tract
after oral administration. The absolute
bioavailability of 250 mg clarithromycin tablets was approximately
50%. For a single 500 mg dose of
clarithromycin, food slightly delays the onset of clarithromycin
absorption, increasing the peak time
from approximately 2 to 2.5 hours. Food also increases the
clarithromycin peak plasma concentration by
about 24%, but does not affect the extent of clarithromycin
bioavailability. Food does not affect the
onset of formation of the antimicrobially active metabolite, 14-OH
clarithromycin or its peak plasma
concentration but does slightly decrease the extent of metabolite
formation, indicated by an 11%
decrease in area under the plasma concentration-time curve (AUC).
Therefore, clarithromyc
