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, clarithromycin tablets
may be given without regard to food.
