Third generation Cephalosporins
Orcef DS – Cefixime 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.

Increased prothrombin time (with or withot bleeding) with anticoagulants (e.g. warfarin). Increased plasma carbamazepine concentrations with concomitant use. Increased bioavailability with nifedipine. Increased serum concentration with probenecid.
Patients with known hypersensitivity to cephalosporin antibiotics, children under 6 months.
Orcef DS – Cefixime is generally well tolerated. The majority of side-effects observed in clinical trials were mild and self-limiting in nature. Diarrhoea, stool changes, nausea, vomiting, abdominal pain, dyspepsia, headache and dizziness.
Pregnancy & Lactation
Pregnancy category B. There are no adequate and well-controlled studies in pregnant women. So this drug should be used during pregnancy only if clearly needed.
Use in Lactation: It is not known whether Orcef DS – cefixime is excreted in human milk. So it is probably best either to avoid using the drug by the nursing mother or to discontinue breast feeding.
Patient with history of penicillin allergy. Renal impairment. Children. Pregnancy and lactation.
Symptoms: Mild to moderate adverse GI effects.
Management: Supportive treatment. Empty stomach by gastric lavage.

Use in elderly: No special precautions are necessary. Old age is not an indication for dose adjustment.
Dosage in renal impairment:
Creatinine clearance: 20 ml/min or greater: normal dose
Creatinine clearance: <20 ml/min or chronic ambulatory peritoneal dialysis
Haemodialysis: daily dose should not exceed 200 mg.
