Cautions for Teflaro


Contraindications



  • Known hypersensitivity to ceftaroline or other cephalosporins.1 (See Sensitivity Reactions under Cautions.)



Warnings/Precautions


Sensitivity Reactions


Hypersensitivity Reactions

Serious, sometimes fatal, anaphylactic reactions and serious skin reactions reported in patients receiving β-lactam antibiotics.1 Anaphylaxis and anaphylactoid reactions have been reported with ceftaroline.1


Discontinue drug if hypersensitivity occurs.1 Serious acute hypersensitivity (e.g., anaphylaxis) reactions require emergency treatment (e.g., epinephrine, airway management, oxygen, IV fluids, antihistamines, corticosteroids, vasopressors) as clinically indicated.1


Cross-hypersensitivity

Partial cross-sensitivity occurs among β-lactam antibiotics.1 27


Prior to initiation of therapy, make careful inquiry concerning previous hypersensitivity reactions to ceftaroline, other cephalosporins, penicillins, or carbapenems.1 Contraindicated in patients hypersensitive to the drug or other cephalosporins; use with caution in those allergic to penicillin or other β-lactams.1


Clostridium difficile-associated Diarrhea and Colitis (CDAD)


Treatment with anti-infectives alters normal colon flora and may permit overgrowth of Clostridium difficile.1 12 13 14 15 16


C. difficile infection (CDI) and C. difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis) have been reported with nearly all systemic anti-infectives, including ceftaroline, and may range in severity from mild diarrhea to fatal colitis.1 12 13 14 15 16 C. difficile produces toxins A and B which contribute to development of CDAD;1 13 12 hypertoxin-producing strains of C. difficile are associated with increased morbidity and mortality since they may be refractory to anti-infectives and colectomy may be required.1


Consider CDAD if diarrhea develops during or after anti-infective therapy and manage accordingly.1 12 13 14 15 16 Obtain a careful medical history since CDAD may occur as late as 2 months or longer after anti-infective therapy is discontinued.1


If CDAD is suspected or confirmed, discontinue anti-infectives not directed against C. difficile whenever possible.1 12 14 15 16 Initiate appropriate supportive therapy (e.g., fluid and electrolyte management, protein supplementation), anti-infective therapy directed against C. difficile (e.g., metronidazole, vancomycin), and surgical evaluation as clinically indicated.1 12 13 14 15 16


Hematologic Effects


Seroconversion from negative to positive direct antiglobulin (Coombs’) tests reported in approximately 11% of patients receiving ceftaroline in phase 3 clinical trials; no evidence of hemolytic anemia in these patients.1


Consider drug-induced hemolytic anemia in patients who develop anemia during or after ceftaroline treatment; perform diagnostic studies, including direct antiglobulin test.1 If drug-induced hemolytic anemia is suspected, consider discontinuing ceftaroline and administer supportive treatment (e.g., transfusion) as clinically indicated.1


Selection and Use of Anti-infectives


To reduce development of drug-resistant bacteria and maintain effectiveness of ceftaroline and other antibacterials, use only for treatment of infections proven or strongly suspected to be caused by susceptible bacteria.1


When selecting or modifying anti-infective therapy, use results of culture and in vitro susceptibility testing.1 In the absence of such data, consider local epidemiology and susceptibility patterns when selecting anti-infectives for empiric therapy.1

Teflaro Pharmacokinetics


Absorption


Ceftaroline is administered as ceftaroline fosamil, a prodrug that is inactive until converted in vivo to ceftaroline by a plasma phosphatase.1 4


Plasma Concentrations


In healthy adults, peak plasma concentrations and AUC increase approximately in proportion to dose following single IV doses of 50–1000 mg of ceftaroline fosamil.1


No appreciable accumulation reported when 600-mg doses are given by IV infusion over 1 hour every 12 hours for up to 14 days in adults with normal renal function.1


Special Populations


In healthy adolescents 12–17 years of age, peak plasma concentrations and AUC after a single 8-mg/kg IV dose (600 mg in those weighing >75 kg) are 10 and 23% lower, respectively, compared with healthy adults who received a single 600-mg IV dose.1


Distribution


Extent


Limited data available regarding tissue distribution; animal data indicate ceftaroline is distributed into kidneys, skin, and lungs.4 9


Not known whether distributed into milk.1


Plasma Protein Binding


Approximately 20%;1 decreases slightly with increasing concentrations >1–50 mcg/mL.1


Elimination


Metabolism


Ceftaroline fosamil is rapidly converted in vivo to ceftaroline by a plasma phosphatase, principally during IV infusion.1 4 In addition, the β-lactam ring of ceftaroline is hydrolyzed to an inactive, open-ring metabolite (ceftaroline M-1).1


Ceftaroline is not a substrate of CYP isoenzymes.1


Elimination Route


Ceftaroline and its metabolites principally eliminated in urine by glomerular filtration.1 Following a single 600-mg IV dose of ceftaroline fosamil, approximately 88% is eliminated in urine (approximately 64% as unchanged drug, and 2% as ceftaroline M-1) and 6% is eliminated in feces within 48 hours.1


Removed by hemodialysis.1


Half-life


Adults: 2.7 hours.1


Special Populations


Pharmacokinetics in patients with hepatic impairment not established.1


AUC and half-life increased in patients with renal impairment.1 4

Actions and Spectrum



  • Based on spectrum of activity, classified as a fifth generation cephalosporin.5 6 7 8 27




  • Like third and fourth generation cephalosporins, ceftaroline has an expanded spectrum of activity that includes both gram-positive and gram-negative bacteria.4 5 6 7 17 21 27 Unlike first, second, third, and fourth generation cephalosporins, ceftaroline has activity against methicillin-resistant S. aureus (MRSA; also known as oxacillin-resistant Staphylococcus aureus, ORSA).4 5 6 7 17 27




  • Usually bactericidal.1 4 17 22




  • Like other β-lactam antibiotics, antibacterial activity results from inhibition of bacterial cell wall synthesis.1




  • Spectrum of activity includes many gram-positive and gram-negative aerobic bacteria1 4 17 18 19 20 21 24 27 and some anaerobic bacteria.23




  • Gram-positive aerobes: Active in vitro against S. aureus (including MRSA, vancomycin-resistant S. aureus [VRSA], and daptomycin-nonsusceptible S. aureus),1 4 17 21 24 27 coagulase-negative staphylococci (including methicillin-resistant [oxacillin-resistant] strains),4 21 27 Streptococcus pneumoniae (including penicillin- or cefotaxime-resistant S. pneumoniae or multidrug-resistant S. pneumoniae [MDRSP]),1 4 18 19 20 21 24 27 S. pyogenes (group A β-hemolytic streptococci),1 4 21 27 S. agalactiae (group B streptococci),1 4 21 27 viridans streptococci,4 21 27 and S. dysgalactiae.1 Has only limited activity against Enterococcus faecalis; E. faecium are resistant.4 21




  • Gram-negative aerobes: Active in vitro against Escherichia coli,1 21 27 Klebsiella pneumoniae,1 21 27 K. oxytoca,1 and Haemophilus influenzae (including β-lactamase-producing strains).1 4 21 27 Also active in vitro against Citrobacter koseri,1 C. freundii,1 21 27 Enterobacter cloacae,1 21 27 E. aerogenes,1 27 Moraxella catarrhalis (including β-lactamase-producing strains),1 4 21 27 Morganella morganii,1 21 Pasteurella multocida,21 Proteus mirabilis,1 21 27 and H. parainfluenzae.1 Inactive against Pseudomonas aeruginosa4 27 .




  • Gram-negative bacteria that produce extended-spectrum β-lactamases (ESBLs) from the TEM, SHV or CTX-M families, AmpC cephalosporinases, class B metallo-β-lactamases, or serine carbapenemases are resistant.1 4 21 27




  • Although cross-resistance may occur between ceftaroline and other cephalosporins, some bacteria resistant to other cephalosporins may be susceptible to ceftaroline.1



Advice to Patients



  • Advise patients that antibacterials (including ceftaroline) should only be used to treat bacterial infections and not used to treat viral infections (e.g., the common cold).1




  • Importance of completing full course of therapy, even if feeling better after a few days.1




  • Advise patients that skipping doses or not completing the full course of therapy may decrease effectiveness and increase the likelihood that bacteria will develop resistance and will not be treatable with ceftaroline or other antibacterials in the future.1




  • Advise patients that diarrhea is a common problem caused by anti-infectives and usually resolves when the drug is discontinued.1 Importance of contacting a clinician if watery or bloody diarrhea occurs.1




  • Importance of informing clinicians of prior hypersensitivity reactions to ceftaroline, other cephalosporins, other β-lactam antibiotics, or other allergens.1 Importance of discontinuing the drug and immediately informing clinician if an allergic or hypersensitivity reaction occurs.1




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and dietary or herbal supplements, as well as any concomitant illnesses.1




  • Importance of women informing their clinician if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of informing patients of other important precautionary information.1 (See Cautions.)
