Drug Index


Mechanism :

Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs), which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis.

Indication :

  • Infections caused by beta-lactamase-producing isolates of S. aureus, Haemophilus influenzae, Klebsiella species, E. coli, Pseudomonas aeruginosa (or other Pseudomonas species), Citrobacter species, Enterobacter cloacae, Serratia marcescens.

Hypersensitivity (history of a serious reaction [e.g., anaphylaxis, Stevens-Johnson syndrome]) to ticarcillin, clavulanate, or to other beta-lactams (e.g., penicillins, cephalosporins).

Dosing :

Infants ≥3 months, Children, and Adolescents: IV
<60 kg: 200 mg ticarcillin/kg/day in divided doses every 6 hours. Maximum: 12 g daily.

Cystic fibrosis (off-label use): IV
400 mg ticarcillin/kg/day in divided doses every 6 hours.

Adverse Effect :

Rash, nausea, diarrhea, phlebitis at injection site, increased eosinophils, increased AST, increased ALT.

Interaction :

Aminoglycosides: Penicillins may decrease the serum concentration of Aminoglycosides.
Tetracyclines: May diminish the therapeutic effect of Penicillins.
Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine.
