Use |
|
Treatment of lower respiratory tract infections, skin and skin structure
infections, bone and joint infections, intra-abdominal and urinary tract
infections, sepsis and meningitis due to susceptible organisms; documented or
suspected infection due to susceptible organisms in home care patients and
patients without I.V. line access; treatment of documented or suspected
gonococcal infection or chancroid; emergency room management of patients at high
risk for bacteremia, periorbital or buccal cellulitis, salmonellosis or
shigellosis, and pneumonia of unestablished etiology (<5 years of age);
treatment of Lyme disease, depends on the stage of the disease (used in Stage II
and Stage III, but not stage I; doxycycline is the drug of choice for Stage
I) |

Contraindications |
|
Hypersensitivity to ceftriaxone sodium, any component, or cephalosporins;
do not use in hyperbilirubinemic neonates, particularly those who are
premature since ceftriaxone is reported to displace bilirubin from albumin
binding sites |
|
|
Warnings/Precautions |
|
Modify dosage in patients with severe renal impairment, prolonged use may
result in superinfection; use with caution in patients with a history of
penicillin allergy, especially IgE-mediated reactions (eg, anaphylaxis,
urticaria); may cause antibiotic-associated colitis or colitis secondary to
C. difficile |
|
|
Adverse
Reactions |
|
1% to 10%:
Dermatologic: Rash (1.7%)
Gastrointestinal: Diarrhea (2.7%)
Hematologic: Eosinophilia (6%), thrombocytosis (5.1%), leukopenia (2.1%)
Hepatic: Elevated transaminases (3.1% to 3.3%)
Local: Pain, induration at injection site (1%)
Renal: Increased BUN (1.2%)
<1%: Phlebitis, pruritus, fever, chills, anemia, hemolytic anemia,
neutropenia, lymphopenia, thrombocytopenia, prolonged PT, nausea, vomiting,
dysgeusia, increased alkaline phosphatase, increased bilirubin, increased
creatinine, urinary casts, headache, dizziness, candidiasis, vaginitis,
diaphoresis, flushing
Other reactions with cephalosporins include anaphylaxis, paresthesia,
Stevens-Johnson syndrome, toxic epidermal necrolysis, erythema multiforme,
angioedema, pseudomembranous colitis, hemolytic anemia, encephalopathy,
asterixis, neuromuscular excitability, seizures, serum-sickness reactions, renal
dysfunction, interstitial nephritis, toxic nephropathy, cholestasis, aplastic
anemia, hemolytic anemia, pancytopenia, agranulocytosis, colitis, hemorrhage,
superinfection |
|
|
Overdosage/Toxicology |
|
Symptoms of overdose include neuromuscular hypersensitivity, convulsions
especially with renal insufficiency; many beta-lactam antibiotics have the
potential to cause neuromuscular hyperirritability or seizures
Hemodialysis may be helpful to aid in the removal of the drug from the blood,
otherwise most treatment is supportive or symptom directed |
|
|
Drug
Interactions |
|
Increased effect:
Aminoglycosides may result in synergistic antibacterial activity
High-dose probenecid decreases clearance
Increased toxicity: Aminoglycosides increase nephrotoxic potential
|
|
|
Stability |
|
Reconstituted solution (100 mg/mL) is stable for 3 days at room temperature
and 3 days when refrigerated; for I.V. infusion in NS or D5W solution
is stable for 3 days at room temperature, 10 days when refrigerated, or 26 weeks
when frozen; after freezing, thawed solution is stable for 3 days at room
temperature or 10 days when refrigerated |
|
|
Mechanism of
Action |
|
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. |

|
Pharmacodynamics/Kinetics |
|
Absorption: I.M.: Well absorbed
Distribution: Widely distributed throughout the body including gallbladder,
lungs, bone, bile, CSF (diffuses into the CSF at higher concentrations when the

Elimination: Excreted unchanged in urine (33% to 65%) by glomerular
filtration and in feces |
