Ceftriaxone

INDICATIONS AND USAGE Before instituting treatment with Ceftriaxone for Injection, USP, appropriate specimens should be obtained for isolation of the causative organism and for determination of its susceptibility to the drug. Therapy may be instituted prior to obtaining results of susceptibility testing. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Ceftriaxone for Injection, USP and other antibacterial drugs, Ceftriaxone for Injection, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Ceftriaxone for Injection, USP is indicated for the treatment of the following infections when caused by susceptible organisms: LOWER RESPIRATORY TRACT INFECTIONS caused by Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Escherichia coli, Enterobacter aerogenes, Proteus mirabilis or Serratia marcescens. ACUTE BACTERIAL OTITIS MEDIA caused by Streptococcus pneumoniae, Haemophilus influenzae (including beta‐lactamase producing strains) or Moraxella catarrhalis (including beta-lactamase producing strains). NOTE: In one study lower clinical cure rates were observed with a single dose of Ceftriaxone for Injection, USP compared to 10 days of oral therapy. In a second study comparable cure rates were observed between single dose of Ceftriaxone for Injection, USP and the comparator. The potentially lower clinical cure rate of Ceftriaxone for Injection, USP should be balanced against the potential advantages of parenteral therapy (see CLINICAL STUDIES ). SKIN AND SKIN STRUCTURE INFECTIONS caused by Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes , Viridans group streptococci, Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Morganella morganii 1 , Pseudomonas aeruginosa, Serratia marcescens, Acinetobacter calcoaceticus, Bacteroides fragilis 1 or Peptostreptococcus species. URINARY TRACT INFECTIONS (complicated and uncomplicated) caused by Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii or Klebsiella pneumoniae. UNCOMPLICATED GONORRHEA (cervical/urethral and rectal) caused by Neisseria gonorrhoeae, including both penicillinase- and nonpenicillinase-producing strains, and pharyngeal gonorrhea caused by nonpenicillinase‐producing strains of Neisseria gonorrhoeae. PELVIC INFLAMMATORY DISEASE caused by Neisseria gonorrhoeae. Ceftriaxone for Injection, USP, like other cephalosporins, has no activity against Chlamydia trachomatis . Therefore, when cephalosporins are used in the treatment of patients with pelvic inflammatory disease and Chlamydia trachomatis is one of the suspected pathogens, appropriate antichlamydial coverage should be added. BACTERIAL SEPTICEMIA caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae or Klebsiella pneumoniae. BONE AND JOINT INFECTIONS caused by Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae or Enterobacter species. INTRA-ABDOMINAL INFECTIONS caused by Escherichia coli, Klebsiella pneumoniae, Bacteroides fragilis, Clostridium species (Note: most strains of Clostridium difficile are resistant) or Peptostreptococcus species. MENINGITIS caused by Haemophilus influenzae, Neisseria meningitidis or Streptococcus pneumoniae. Ceftriaxone for Injection, USP has also been used successfully in a limited number of cases of meningitis and shunt infection caused by Staphylococcus epidermidis 1 and Escherichia coli. 1 1 Efficacy for this organism in this organ system was studied in f …

DOSAGE AND ADMINISTRATION Ceftriaxone may be administered intravenously or intramuscularly. Do not use diluents containing calcium, such as Ringer's solution or Hartmann's solution, to reconstitute ceftriaxone vials or to further dilute a reconstituted vial for IV administration because a precipitate can form. Precipitation of ceftriaxone-calcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same IV administration line. Ceftriaxone must not be administered simultaneously with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition via a Y-site. However, in patients other than neonates, ceftriaxone and calcium-containing solutions may be administered sequentially of one another if the infusion lines are thoroughly flushed between infusions with a compatible fluid (see WARNINGS ). There have been no reports of an interaction between ceftriaxone and oral calcium-containing products or interaction between intramuscular ceftriaxone and calcium-containing products (IV or oral). NEONATES: Hyperbilirubinemic neonates, especially prematures, should not be treated with ceftriaxone. Ceftriaxone is contraindicated in premature neonates (see CONTRAINDICATIONS ). Ceftriaxone is contraindicated in neonates (≤ 28 days) if they require (or are expected to require) treatment with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition because of the risk of precipitation of ceftriaxone-calcium (see CONTRAINDICATIONS ). Intravenous doses should be given over 60 minutes in neonates to reduce the risk of bilirubin encephalopathy. PEDIATRIC PATIENTS: For the treatment of skin and skin structure infections, the recommended total daily dose is 50 to 75 mg/kg given once a day (or in equally divided doses twice a day). The total daily dose should not exceed 2 grams. For the treatment of acute bacterial otitis media, a single intramuscular dose of 50 mg/kg (not to exceed 1 gram) is recommended (see INDICATIONS AND USAGE ). For the treatment of serious miscellaneous infections other than meningitis, the recommended total daily dose is 50 to 75 mg/kg, given in divided doses every 12 hours. The total daily dose should not exceed 2 grams. In the treatment of meningitis, it is recommended that the initial therapeutic dose be 100 mg/kg (not to exceed 4 grams). Thereafter, a total daily dose of 100 mg/kg/day (not to exceed 4 grams daily) is recommended. The daily dose may be administered once a day (or in equally divided doses every 12 hours). The usual duration of therapy is 7 to 14 days. ADULTS: The usual adult daily dose is 1 to 2 grams given once a day (or in equally divided doses twice a day) depending on the type and severity of infection. The total daily dose should not exceed 4 grams. If Chlamydia trachomatis is a suspected pathogen, appropriate antichlamydial coverage should be added, because ceftriaxone sodium has no activity against this organism. For the treatment of uncomplicated gonococcal infections, a single intramuscular dose of 250 mg is recommended. For preoperative use (surgical prophylaxis), a single dose of 1 gram administered intravenously 1/2 to 2 hours before surgery is recommended. Generally, ceftriaxone therapy should be continued for at least 2 days after the signs and symptoms of infection have disappeared. The usual duration of therapy is 4 to 14 days; in complicated infections, longer therapy may be required. When treating infections caused by Streptococcus pyogenes , therapy should be continued for at least 10 days. No dosage adjustment is necessary for patients with impairment of renal or hepatic function (see PRECAUTIONS ). The dosages recommended for adults require no modification in elderly patients, up to 2 g per day, provided there is no severe renal and hepatic impairment (see PRECAUTIONS ). DIRECTIONS FOR USE: Intramuscular Administration: Reconstitute ceftriaxone powder with …

CONTRAINDICATIONS Hypersensitivity Ceftriaxone for injection is contraindicated in patients with known hypersensitivity to ceftriaxone, any of its excipients or to any other cephalosporin. Patients with previous hypersensitivity reactions to penicillin and other beta lactam antibacterial agents may be at greater risk of hypersensitivity to ceftriaxone (see WARNINGS – Hypersensitivity). Neonates Premature neonates : Ceftriaxone for injection is contraindicated in premature neonates up to a postmenstrual age of 41 weeks (gestational age + chronological age). Hyperbilirubinemic neonates : Hyperbilirubinemic neonates, should not be treated with ceftriaxone for injection. Ceftriaxone can displace bilirubin from its binding to serum albumin, leading to a risk of bilirubin encephalopathy in these patients. Neonates Requiring Calcium Containing IV Solutions Ceftriaxone for injection is contraindicated in neonates (≤ 28 days) if they require (or are expected to require) treatment with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition because of the risk of precipitation of ceftriaxone-calcium (see CLINICAL PHARMACOLOGY, WARNINGS and DOSAGE AND ADMINISTRATION ). Cases of fatal outcomes in which a crystalline material was observed in the lungs and kidneys at autopsy have been reported in neonates receiving ceftriaxone for injection and calcium-containing fluids. In some of these cases, the same intravenous infusion line was used for both ceftriaxone for injection and calcium-containing fluids and in some a precipitate was observed in the intravenous infusion line. There have been no similar reports in patients other than neonates. Lidocaine Intravenous administration of ceftriaxone solutions containing lidocaine is contraindicated. When lidocaine solution is used as a solvent with ceftriaxone for intramuscular injection, exclude all contraindications to lidocaine. Refer to the prescribing information of lidocaine.

ADVERSE REACTIONS Ceftriaxone for injection is generally well tolerated. In clinical trials, the following adverse reactions, which were considered to be related to ceftriaxone for injection therapy or of uncertain etiology, were observed: LOCAL REACTIONS - pain, induration and tenderness was 1% overall. Phlebitis was reported in < 1% after IV administration.

Postmarketing Experience In addition to the adverse reactions reported during clinical trials, the following adverse experiences have been reported during clinical practice in patients treated with ceftriaxone for injection. Data are generally insufficient to allow an estimate of incidence or to establish causation. A small number of cases of fatal outcomes in which a crystalline material was observed in the lungs and kidneys at autopsy have been reported in neonates receiving ceftriaxone for injection and calcium-containing fluids. In some of these cases, the same intravenous infusion line was used for both ceftriaxone for injection and calcium-containing fluids and in some a precipitate was observed in the intravenous infusion line. At least one fatality has been reported in a neonate in whom ceftriaxone for injection and calcium-containing fluids were administered at different time points via different intravenous lines; no crystalline material was observed at autopsy in this neonate. There have been no similar reports in patients other than neonates. GASTROINTESTINAL – pancreatitis, stomatitis and glossitis. GENITOURINARY – oliguria, ureteric obstruction, post-renal acute renal failure. DERMATOLOGIC – exanthema, allergic dermatitis, urticaria, edema; acute generalized exanthematous pustulosis (AGEP) and isolated cases of severe cutaneous adverse reactions (erythema multiforme, Stevens-Johnson syndrome or Lyell’s syndrome/toxic epidermal necrolysis) have been reported. HEMATOLOGICAL CHANGES: Isolated cases of agranulocytosis (< 500/mm 3 ) have been reported, most of them after 10 days of treatment and following total doses of 20 g or …

8 USE IN SPECIFIC POPULATIONS Hepatic impairment: Patients with both hepatic and renal impairment should not receive more than 2 grams of ceftriaxone per day. ( 5.7 ) Renal Impairment: This formulation of Ceftriaxone for Injection USP – Pharmacy Bulk Package bag, SmartPak ® should not be used in renally impaired patients who require less than the 1 gram dose of ceftriaxone. Patients with both hepatic and renal impairment should not receive more than 2 grams of ceftriaxone per day. ( 5.7 ) Pediatric Patients: This formulation of Ceftriaxone for Injection USP – Pharmacy Bulk Package bag, SmartPak ® should not be used in pediatric patients who require less than the 1 gram adult dose of ceftriaxone. ( 2.2 , 8.4 ) 8.1 Pregnancy Pregnancy Category B. Reproductive studies have been performed in mice, rats, and primates at intravenous doses of 625, 586, and 84 mg/kg/day, respectively without evidence of embryotoxicity, fetotoxicity, or teratogenicity. These doses are approximately 1.5, 2.8, and 0.8 times the recommended clinical dose of 2 grams/day based on body surface area comparisons. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Ceftriaxone was tested in a Segment III (pre-postnatal) study in rats at intravenous doses of up to 586 mg/kg/day approximately 2.8 times (mg/m 2 comparison) the recommended daily dose of 2 grams/day. No adverse effects were noted on various reproductive parameters during gestation and lactation, including postnatal growth, functional behavior, and reproductive ability of the offspring. 8.3 Nursing Mothers Ceftriaxone is excreted in human breast milk. Caution should be exercised when Ceftriaxone for Injection is administered to a nursing woman. 8.4 Pediatric Use Ceftriaxone for Injection USP, Pharmacy Bulk Package bag, SmartPak ® should not be used in pediatric patients who require less than the 1 gram dose of ceftriaxone. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the adult 1 gram dose of ceftriaxone. 8.5 Geriatric Use Of the total number of subjects in clinical studies of ceftriaxone sodium, 32% were 60 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Ceftriaxone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. The pharmacokinetics of ceftriaxone were only minimally altered in geriatric patients compared to healthy adult subjects, and dosage adjustments are not necessary for geriatric patients with ceftriaxone dosages up to 2 grams per day [see Clinical Pharmacology (12) ].

Mechanism of Action Ceftriaxone is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Ceftriaxone has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-negative and Gram-positive bacteria.
