Clarithromycin tablets are indicated for the treatment of mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions as listed below: Pharyngitis/Tonsillitis due to Streptococcus pyogenes (The usual drug of choice in the treatment and prevention of streptococcal infections and the prophylaxis of rheumatic fever is penicillin administered by either the intramuscular or the oral route. Clarithromycin is generally effective in the eradication of S. pyogenes from the nasopharynx; however, data establishing the efficacy of clarithromycin in the subsequent prevention of rheumatic fever are not available at present.)

CLARITHROMYCIN - CLARITHROMYCIN TABLET
LIFE LINE HOME CARE SERVICES, INC.
----------
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.
NOTE: When testing _Streptococcus_ spp., including _Streptococcus
pneumoniae,_ susceptibility and resistance
to clarithromycin can be predicted using erythromycin.
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.
Each clarithromycin tablet intended for oral administration contains
250 mg or 500 mg of
clarithromycin. In addition, each clarithromycin tablet contains the
following inactive ingredients:
croscarmellose sodium, hypromellose, magnesium stearate,
microcrystalline cellulose, polyethylene
glycol, polysorbate 80, povidone, talc, and titanium dioxide.
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 concent
