New page

==General==
*Type: [[Is Generation::3rd generation]] [[Is DrugClass::Cephalosporin]]
*Dosage Forms: powder for injection
*Dosage Strengths: 1g, 2g, 10g
*Routes of Administration: IV, IM
*Common Trade Names: Cefobid

==Adult Dosing==
===General===
*Mild-Moderate: 1-2g IM/IV q12h
*Severe: 2-4g IM/IV q8h or 3-4g q12h
*Max: 12g/day (total daily dose)

===[[HAP]]/[[VAP]], Pseudomonas===
*2g IV q8h or 3g IV q12h
*Often used in combination with another anti-pseudomonal agent

===Complicated [[Intra-abdominal Infections]]===
*2g IV q12h
*Usually combined with metronidazole or used as Cefoperazone/Sulbactam

===Complicated [[UTI]] and Gynecological Infections===
*2g IV q12h

==Pediatric Dosing==
===General===
*Neonates (<8 days): Not recommended
*Infants/Children: 50-200mg/kg/day IM/IV divided q12h
*Max: 12g/day

==Special Populations==
*Pregnancy: B
*Lactation: Low distribution into milk; generally compatible
*Renal
**Adult
***No adjustment necessary for renal impairment alone (primary excretion is biliary)
***Hemodialysis: Schedule dose to follow dialysis
**Pediatric
***No adjustment defined
*Hepatic
**Modification required in severe obstruction or severe hepatic disease
**Max dose 1-2g/day if severe hepatic dysfunction + renal impairment exist

==Contraindications==
*Allergy to class/drug (Cephalosporins)
*History of severe hypersensitivity to penicillin

==Adverse Reactions==
===Serious===
*[[Anaphylaxis]]
*[[Stevens-Johnson Syndrome]]
*[[Clostridium difficile]]
*Hypoprothrombinemia (Bleeding risk due to MTT side chain)
*Disulfiram-like reaction (Alcohol intolerance)

===Common===
*[[Diarrhea]] (Higher incidence than other cephalosporins due to biliary excretion)
*[[Rash]]
*Phlebitis at injection site
*Eosinophilia
*Reversible Neutropenia

==Pharmacology==
*Half-life: 2.0h
*Metabolism: Hepatic (not extensively metabolized, but extensively excreted via bile)
*Excretion: Bile (70-75%), Urine (20-30%)
*Mechanism of Action: Bactericidal; inhibits cell wall mucopeptide synthesis. Contains N-methylthiotetrazole (MTT) side chain.
