Pharmacology

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. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Use: Labeled Indications

Acute bacterial otitis media: Caused by Streptococcus pneumoniae, Haemophilus influenzae (including beta-lactamase-producing strains), or Moraxella catarrhalis (including beta-lactamase-producing strains).

Bacterial septicemia: Caused by Staphylococcus aureus, S. pneumoniae, Escherichia coli, H. influenzae, or Klebsiella pneumoniae.

Bone and joint infections: Caused by S. aureus, S. pneumoniae, E. coli, Proteus mirabilis, K. pneumoniae, or Enterobacter spp.

Intra-abdominal infections: Caused by E. coli, K. pneumoniae, Bacteroides fragilis, Clostridium spp. (most strains of C. difficile are resistant), or Peptostreptococcus spp.

Lower respiratory tract infections: Caused by S. pneumoniae, S. aureus, H. influenzae, Haemophilus parainfluenzae, K. pneumoniae, E. coli, Enterobacter aerogenes, P. mirabilis, or Serratia marcescens.

Meningitis: Caused by H. influenzae, Neisseria meningitidis, or S. pneumoniae. Ceftriaxone has also been used successfully in a limited number of cases of meningitis and shunt infection caused by Staphylococcus epidermidis and E. coli (efficacy for these 2 organisms in this organ system was studied in fewer than 10 infections).

Pelvic inflammatory disease: Caused by N. gonorrhoeae. Ceftriaxone, like other cephalosporins, has no activity against Chlamydia trachomatis. Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and C. trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added.

Skin and skin structure infections: Caused by S. aureus, S. epidermidis, Streptococcus pyogenes, viridans group streptococci, E. coli, Enterobacter cloacae, Klebsiella oxytoca, K. pneumoniae, P. mirabilis, Morganella morganii (efficacy for this organism in this organ system was studied in fewer than 10 infections), Pseudomonas aeruginosa, S. marcescens, Acinetobacter calcoaceticus, or B. fragilis (efficacy for this organism in this organ system was studied in fewer than 10 infections), or Peptostreptococcus spp.

Surgical prophylaxis: Reduce the incidence of postoperative infections in patients undergoing surgical procedures classified as contaminated or potentially contaminated (eg, vaginal or abdominal hysterectomy or cholecystectomy for chronic calculous cholecystitis in high-risk patients, such as those older than 70 years, with acute cholecystitis not requiring therapeutic antimicrobials, obstructive jaundice, or common duct bile stones) and in surgical patients for whom infection at the operative site would present serious risk (eg, during coronary artery bypass surgery).

Uncomplicated gonorrhea (cervical/urethral and rectal): Caused by N. gonorrhoeae, including both penicillinase- and nonpenicillinase-producing strains, and pharyngeal gonorrhea caused by nonpenicillinase-producing strains of N. gonorrhoeae.

Urinary tract infections (complicated and uncomplicated): Caused by E. coli, P. mirabilis, Proteus vulgaris, M. morganii, or K. pneumoniae.

Reconstitution

IM injection: Vials should be reconstituted with appropriate volume of diluent (including D5W, NS, SWFI, bacteriostatic water, or 1% lidocaine) to make a final concentration of 250 mg/mL or 350 mg/mL.

Volume to add to create a 250 mg/mL solution:

250 mg vial: 0.9 mL

500 mg vial: 1.8 mL

1 g vial: 3.6 mL

2 g vial: 7.2 mL

Volume to add to create a 350 mg/mL solution:

500 mg vial: 1.0 mL

1 g vial: 2.1 mL

2 g vial: 4.2 mL

IV infusion: Infusion is prepared in two stages: Initial reconstitution of powder, followed by dilution to final infusion solution.

Vials: Reconstitute powder with appropriate IV diluent (including SWFI, D5W, D10W, NS) to create an initial solution of ~100 mg/mL. Recommended volume to add:

250 mg vial: 2.4 mL

500 mg vial: 4.8 mL

1 g vial: 9.6 mL

2 g vial: 19.2 mL

Note: After reconstitution of powder, further dilution into a volume of compatible solution (eg, 50-100 mL of D5W or NS) is recommended.

Piggyback bottle: Reconstitute powder with appropriate IV diluent (D5W or NS) to create a resulting solution of ~100 mg/mL. Recommended initial volume to add:

1 g bottle:10 mL

2 g bottle: 20 mL

Note: After reconstitution, to prepare the final infusion solution, further dilution to 50 mL or 100 mL volumes with the appropriate IV diluent (including D5W or NS) is recommended.

Administration

Do not coadminister with calcium-containing solutions.

IM: Inject deep IM into large muscle mass; a concentration of 250 mg/mL or 350 mg/mL is recommended for all vial sizes except the 250 mg size (250 mg/mL is suggested); can be diluted with 1:1 water or 1% lidocaine for IM administration only.

IV: Infuse as an intermittent infusion over 30 minutes. IV push administration over 1 to 4 minutes has been reported in children ≥12 years, adolescents, and adults (concentration: 100 mg/mL), primarily in patients outside the hospital setting (Baumgartner 1983; Garrelts 1988; Poole 1999), although a 2 g dose administered IV push over 5 minutes resulted in tachycardia, restlessness, diaphoresis, and palpitations in one patient (Lossos 1994). IV push administration in young infants may also have been a contributing factor in risk of cardiopulmonary events occurring from interactions between ceftriaxone and calcium (Bradley 2009).

Calcium Salts (Intravenous): May enhance the adverse/toxic effect of CefTRIAXone. Ceftriaxone binds to calcium forming an insoluble precipitate. Management: Use of ceftriaxone with calcium-containing solutions within 48 hours of one another is contraindicated in neonates (28 days of age or younger). In older patients, flush lines with compatible fluid between administration. Consider therapy modification

Cholera Vaccine: Antibiotics may diminish the therapeutic effect of Cholera Vaccine. Avoid combination

Lactobacillus and Estriol: Antibiotics may diminish the therapeutic effect of Lactobacillus and Estriol. Monitor therapy

Probenecid: May increase the serum concentration of Cephalosporins. Monitor therapy

Ringer's Injection (Lactated): May enhance the adverse/toxic effect of CefTRIAXone. Ceftriaxone binds to calcium in the Lactated Ringer's forming an insoluble precipitate. Management: Use of ceftriaxone with calcium-containing solutions (including LR) within 48 hours of one another is contraindicated in neonates (28 days of age or younger). In older patients, flush lines with compatible fluid between administration. Consider therapy modification

Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Consider therapy modification

Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine. Only the live attenuated Ty21a strain is affected. Management: Vaccination with live attenuated typhoid vaccine (Ty21a) should be avoided in patients being treated with systemic antibacterial agents. Use of this vaccine should be postponed until at least 3 days after cessation of antibacterial agents. Consider therapy modification

Vitamin K Antagonists (eg, warfarin): Cephalosporins may enhance the anticoagulant effect of Vitamin K Antagonists. Monitor therapy

Warnings/Precautions

Concerns related to adverse effects:

• Hypersensitivity: Serious and sometimes fatal hypersensitivity has been reported. Use caution in patients with a history of any allergy (particularly drugs), penicillin allergy or beta-lactam sensitivity. If severe hypersensitivity occurs, discontinue immediately and institute supportive emergency measures.

• Elevated INR: May be associated with increased INR (rarely), especially in nutritionally-deficient patients, prolonged treatment, hepatic or renal disease. Monitor INR during treatment if patient has impaired synthesis or low stores of vitamin K; supplementation may be needed if clinically indicated.

• Hemolytic anemia: Severe cases (including some fatalities) of immune-related hemolytic anemia have been reported in patients receiving cephalosporins, including ceftriaxone.

• Pancreatitis: Secondary to biliary obstruction, pancreatitis has been reported rarely. Most patients had biliary stasis or sludge risk factors (eg, preceding major surgery, sever illness, TPN).

• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.

Disease-related concerns:

• Gallbladder pseudolithiasis: Abnormal gallbladder sonograms have been reported, possibly due to ceftriaxone-calcium precipitates; probability is greatest in pediatric patients. Discontinue in patients who develop signs and symptoms and/or sonographic evidence of gallbladder disease.

• Gastrointestinal disease: Use with caution in patients with a history of GI disease, especially colitis.

• Renal/hepatic impairment (concurrent) Use with caution in patients with concurrent hepatic dysfunction and significant renal disease; dosage should not exceed 2 g/day.

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.

Special populations:

• Neonates: Use extreme caution in neonates due to risk of hyperbilirubinemia, particularly in premature infants (contraindicated in hyperbilirubinemic neonates and neonates <41 weeks postmenstrual age). Fatal precipitation reactions in neonates due to coadministration of calcium-containing solutions have been reported; concurrent use in neonates is contraindicated.

Other warnings/precautions:

• Precipitation: Ceftriaxone may complex with calcium causing precipitation. Fatal lung and kidney damage associated with calcium-ceftriaxone precipitates has been observed in premature and term neonates. Due to reports of precipitation reaction in neonates, do not reconstitute, admix, or coadminister with calcium-containing solutions (eg, LR, Hartmann’s solution, parenteral nutrition), even via separate infusion lines/sites or at different times in any neonate. Ceftriaxone should not be diluted or administered simultaneously with any calcium-containing solution via a Y-site in any patient. However, ceftriaxone and calcium-containing solutions may be administered sequentially of one another for use in patients other than neonates if infusion lines are thoroughly flushed (with a compatible fluid) between infusions.

Monitoring Parameters

Prothrombin time/INR. Observe for signs and symptoms of anaphylaxis.

Pregnancy Risk Factor

B

Pregnancy Considerations

Adverse events have not been observed in animal reproduction studies. Ceftriaxone crosses the placenta. Pregnancy was found to influence the single dose pharmacokinetics of ceftriaxone when administered prior to delivery (Popović 2007). The pharmacokinetics of ceftriaxone following multiple doses in the third trimester are similar to those of nonpregnant patients (Bourget Fernandez 1993). Ceftriaxone is recommended for use in pregnant women for the treatment of gonococcal infections, Lyme disease, and may be used in certain situations prior to vaginal delivery in women at high risk for endocarditis (consult current guidelines) (ACOG 120, 2011; CDC [Workowski 2015]; Wormser 2006).

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience injection site irritation or diarrhea. Have patient report immediately to prescriber signs pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), signs of gallstones (pain in the upper right abdominal area, right shoulder area, or between the shoulder blades; yellow skin or eyes; or fever with chills), signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, or weight gain), signs of hemolytic anemia (severe loss of strength and energy, dark urine, or jaundice), back pain, abdominal pain, blood in urine, confusion, hallucinations, change in balance, passing out, extra muscle movement, seizures, or signs of Clostridium difficile (C. diff)-associated diarrhea (stomach pain or cramps, very loose or watery stools, or bloody stools) (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
