Indications & Uses

Pharmacology

Cefditoren is delivered as Cefditoren Pivoxil, a broad-spectrum third-generation cephalosporin antibiotic. It is a prodrug, hydrolyzed by esterases during absorption, so the active form, Cefditoren, is what circulates in the blood. Cefditoren acts against both gram-positive and gram-negative organisms. Its bactericidal effect comes from blocking cell wall synthesis, achieved by binding to penicillin-binding proteins (PBPs). Cefditoren also holds up well against several ß-lactamases, including penicillinases and certain cephalosporinases.

Dosage Reference

Cautions & Contraindications

Warnings & Precautions

Cefdiren is not recommended for prolonged antibiotic treatment, since other pivalate-containing compounds have caused clinical signs of carnitine deficiency when used over a period of months. Prescribing Cefdiren without a proven or strongly suspected bacterial infection, or without a prophylactic indication, is unlikely to benefit the patient and raises the risk of developing drug-resistant bacteria.

Contraindications

Cefditoren should not be used in patients who are allergic to cephalosporin antibiotics or to any of its ingredients. It also contains sodium caseinate, a milk protein, so patients with a genuine milk protein allergy (as opposed to lactose intolerance) should avoid taking Cefditoren.

Pregnancy & Breastfeeding

Pregnancy category B. No adequate, well controlled studies have been conducted in pregnant women, so Cefditoren should be used during pregnancy only if clearly needed. Animal studies show that Cefditoren passes into breast milk, so caution should be exercised when giving it to nursing mothers.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

Children: Cefditoren is not recommended for children under 12 years of age. Its safety and efficacy in Cefditoren tablets for this age group, including any effects of altered carnitine concentration, have not been established.

Geriatric patients: No dose adjustment is needed for geriatric patients whose kidney function is normal for their age.

Patients with renal insufficiency: No dose adjustment is needed for mild renal impairment (ClCr: 50-80 mL/min/1.73 m2). In moderate renal impairment (ClCr: 30-49 mL/min/1.73 m2), no more than 200 mg BID should be given. In severe renal impairment (ClCr: <30 mL/min/1.73 m2), the recommended dose is 200 mg QD. The right dose for patients with end-stage renal disease has not been determined.

Patients with hepatic disease: No dose adjustment is needed for mild or moderate hepatic impairment.

Overdose

No information is available on Cefditoren overdose in humans. With other ß-lactam antibiotics, though, overdose has caused nausea, vomiting, epigastric distress, diarrhea and convulsions. Hemodialysis may help remove Cefditoren from the body, particularly if kidney function is compromised.

⚠️ In an emergency call 999 or go to the nearest hospital emergency department.
