Ceftaroline Fosamil

Generic name: ceftaroline systemic

Brand names: Teflaro

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Solution Reconstituted, Intravenous [preservative free]:

Teflaro: 400 mg (1 ea); 600 mg (1 ea)


Mechanism of Action

Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) 1 through 3. This action blocks the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls and inhibits cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysis and murein hydrolases) while cell wall assembly is arrested. Ceftaroline has a strong affinity for PBP2a, a modified PBP in MRSA, and PBP2x in S. pneumoniae, contributing to its spectrum of activity against these bacteria.



Vd: Median: 20.3 L (range: 18.3 to 21.6 L)


Ceftaroline fosamil (inactive prodrug) undergoes rapid conversion to bioactive ceftaroline in plasma by phosphatase enzyme; ceftaroline is hydrolyzed to form inactive ceftaroline M-1 metabolite


Urine (~88%); feces (~6%)

Time to Peak

~1 hour

Half-Life Elimination

1.6 ± 0.38 hours (single dose); 2.66 ± 0.4 hours (multiple dose)

Protein Binding


Use in Specific Populations

Special Populations: Renal Function Impairment

AUC increased 52% in moderate renal impairment (CrCl >30 to 50 mL/minute) and 115% in severe renal impairment (CrCl 15 to 30 mL/minute) as compared to patients with normal renal function. Following a 4-hour hemodialysis session, 21.6% of a single 400 mg IV dose (administered prior to hemodialysis) was recovered in the dialysate.

Special Populations: Elderly

The AUC was approximately 33% higher in elderly patients, mainly because of changes in renal function.

Use: Labeled Indications

Reconstitute 400 mg or 600 mg vial with 20 mL SWFI, NS, D5W, or LR. Mix gently to reconstitute (<2 minutes). Reconstituted solution (400 mg vial = 20 mg/mL, 600 mg vial = 30 mg/mL) should be further diluted for IV administration in a compatible solution not to exceed a final concentration of 12 mg/mL. To prepare a 400 or 600 mg dose, withdraw 20 mL of diluent from 50 mL IV bag; inject the entire contents of the ceftaroline vial (also 20 mL) to achieve a total volume of 50 mL; resulting concentration is 12 mg/mL (600 mg vial) or 8 mg/mL (400 mg vial). Use the same solution as used for reconstitution (Note: If SWFI was used for reconstitution, then appropriate infusion solutions include NS, 1/2NS, D5W, D2.5W, or LR). Color of infusion solutions ranges from clear and light to dark yellow depending on concentration and storage conditions; potency is not affected.


IV: Administer by slow IV infusion over 5 to 60 minutes.


Store unused vials at 25°C (77°F); excursions permitted between 15°C and 30°C (59°F and 86°F). Diluted solutions in D2.5W, 1/2NS, D5W, LR, or NS (in infusion bags or Mini-Bag Plus) should be used within 6 hours when stored at room temperature or within 24 hours if refrigerated at 2°C to 8°C (36°F to 46°F).

Concerns related to adverse effects:

  • Hemolytic anemia: Seroconversion from a negative to a positive direct Coombs’ test has been reported. Hemolytic anemia was not reported in clinical studies; however, if anemia develops during or after treatment, consider drug-induced hemolytic anemia. Diagnostic tests should include a direct Coombs’ test. If hemolytic anemia is suspected, discontinue the drug and institute supportive care as clinically indicated.
  • Hypersensitivity: Serious hypersensitivity (anaphylactic) and skin reactions have occurred with ceftaroline. Use with caution in patients with a history of penicillin, cephalosporin, or carbapenem allergy. Maintain clinical supervision if given to penicillin or beta-lactam allergic patients; cross sensitivity among beta-lactam antibacterial agents has been reported. If a serious reaction occurs, discontinue the drug and institute supportive measures as clinically indicated.
  • Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis (including fatalities); CDAD has been observed >2 months postantibiotic treatment.

Disease-related concerns:

  • Renal impairment: Use with caution in patients with renal impairment (CrCl ≤50 mL/minute); dosage adjustments recommended.

Concurrent drug therapy issues:

  • Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Monitoring Parameters

Obtain specimen for culture and susceptibility prior to the first dose. Monitor for signs of anaphylaxis during first dose. Monitor renal function.
