Chống chỉ định
Hypersensitivity to cefpodoxime or other cephalosporins.
Patient w/ history of penicillin allergy. Renal impairment. Childn. Pregnancy and lactation.
Monitor renal function; observe for signs and symptoms of anaphylaxis during 1st dose.
Symptoms: Nausea, vomiting, epigastric distress and diarrhoea. Management: Haemodialysis or peritoneal dialysis may be useful in the event of a serious toxic reaction particularly if renal function is compromised.
Antacids or H2-blockers may decrease the absorption of cefpodoxime. Reduced renal excretion w/ probenecid.
Cefpodoxime levels may be increased w/ food.
Urinary glucose test using cupric sulfate (e.g. Benedict's or Fehling's tests soln, Clinitest®) may produce false-positive result. May induce a positive direct Coombs' test; false-positive serum or urine creatinine w/ Jaffe' reaction.
Description: Cefpodoxime binds to 1 or more of the penicillin-binding proteins (PBPs) which inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death. Pharmacokinetics: Absorption: Rapid and well absorbed from the GI tract (approx 50%). Decreased absorption in low gastric acidity conditions. Food may increase bioavailability. Bioavailability: Approx 50%. Time to peak plasma concentration: Approx 2-3 hr. Distribution: Reaches bile, resp and genito-urinary tract (therapeutic concentrations); enters breast milk (low concentrations). Plasma protein binding: Approx 20-30%. Metabolism: De-esterified to cefpodoxime in the intestinal lumen. Excretion: Via urine (80% as unchanged drug). Plasma half-life: Approx 2-3 hr.
Store between 20-25°C. Reconstituted powd: Store between 2-8°C.
