Pharmacology

Cefpodoxime is an oral 3rd generation cephalosporin, which has good stability to beta lactamases and activity against Gram negative and Gram positive bacteria. It is indicated for the treatment of infections either before the infecting organism has been identified. It is a prodrug its active metabolite is Cefpodoxime. Approximately 29 to 33% of Cefpodoxime excreted unchanged in the urine in 12 hours.

Interaction

Cefpodoxime concomitant administration of high doses of antacids (sodium bicarbonate and aluminum hydroxide) or H2 blockers reduces peak plasma levels and the extent of absorption respectively. Renal excretion of Cefpodoxime is inhibit by probenecid.

Contraindications

Cefpodoxime is contraindicated in patients with known allergy to cephalosporins.

Side Effects

Cefpodoxime has very few side effects. Possible side effects include gastrointestinal disorders (such as- diarrhea, nausea, vomiting and abdominal pain), rash, urticaria and itching.

Pregnancy & Lactation

US FDA pregnancy category of Cefpodoxime is B. There is, however, no adequate and well-controlled study in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Cefpodoxime have been shown to be excreted in human milk. So, caution should be exercised when Cefpodoxime is administered to a nursing woman.

Precautions & Warnings

In patients with transient or persistent reduction in urinary output due to renal insufficiency, the total daily dose of Cefpodoxime should be reduced. Cefpodoxime should be administered with caution to patients receiving concurrent treatment with potent diuretics. As with other antibiotics, prolonged use of Cefpodoxime may result in overgrowth of non-susceptible organisms.

Use in Special Populations

Patients with severe renal impairment (creatinin clearance <30 ml/min) the dosing intervals should be increased to 24 hourly. The dosage adjustment is not require in cases of hepatic impairment.
