Drug Interactions
Oral Contraceptives: Multiple doses of cefditoren pivoxil had no effect on the pharmacokinetics of ethinyl estradiol, the estrogenic component in most oral contraceptives.
Antacids: Co-administration of a single dose of an antacid which contained both magnesium (800 mg) and aluminum (900 mg) hydroxides reduced the oral absorption of a single 400 mg dose of cefditoren pivoxil administered following a meal, as evidenced by a 14% decrease in mean Cmax and an 11% decrease in mean AUC. Although the clinical significance is not known, it is not recommended that cefditoren pivoxil be taken concomitantly with antacids.
H2-Receptor Antagonists: Co-administration of a single dose of intravenously administered famotidine (20 mg) reduced the oral absorption of a single 400 mg dose of cefditoren pivoxil administered following a meal, as evidenced by a 27% decrease in mean Cmax and a 22% decrease in mean AUC. Although the clinical significance is not known, it is not recommended that cefditoren pivoxil be taken concomitantly with H2-receptor antagonists.
Probenecid: As with other β-lactam antibiotics, co-administration of probenecid with cefditoren pivoxil resulted in an increase in the plasma exposure of cefditoren, with a 49% increase in mean Cmax, a 122% increase in mean AUC, and a 53% increase in t½.
Drug/Laboratory Test Interactions: Cephalosporins are known to occasionally induce a positive direct Coombs’ test. A false-positive reaction for glucose in the urine may occur with copper reduction tests (Benedict’s or Fehling’s solution or with CLINITEST tablets), but not with enzymebased tests for glycosuria (eg, CLINISTIX, TES-TAPE). As a false-negative result may occur in the ferricyanide test, it is recommended that either the glucose oxidase or hexokinase method be used to determine blood/plasma glucose levels in patients receiving cefditoren pivoxil.
