CEPHRADINE IS ALMOST COMPLETELY ABSORBED AFTER ORAL ADMIN; IN PRESENCE OF FOOD, ABSORPTION IS SLOWED BUT NOT DECR. ORAL DOSES OF 250 & 500 MG YIELD PEAK PLASMA LEVELS OF ABOUT 9 & 16.5 UG/ML, WITHIN 40 MIN FROM EMPTY STOMACH. ABSORPTION BY IM ROUTE IS CONSIDERABLY SLOWER.
AFTER SINGLE ORAL ADMIN, CEPHRADINE WAS ABSORBED RAPIDLY FROM GI TRACT & PEAK SERUM CONCN ACHIEVED WITHIN 1 HR. 75-100% OF DOSE EXCRETED UNCHANGED IN URINE IN FIRST 6 HOURS.
SIX SUBJECTS RECEIVED 1 G EACH OF CEPHRADINE (I) & CEPHALEXIN (II) EVERY 4 HR FOR 7 DOSES & 5 RECEIVED 2 G EVERY 6 HR FOR 5 DOSES. PEAK SERUM LEVELS FOR I & II WERE 29 & 35 UG/ML, RESPECTIVELY, FOLLOWING 1 G & 45-50 UG/ML FOLLOWING 2 G.
