Ceftriaxone Sodium & Sulbactam for Injection 1.5g
Pharmacotherapeutic group: Third generation cephalosporins; ATC code: J01DD54.
Ceftriaxone Sulbactam Injection improves the patient’s condition by performing the following functions:
Preventing destruction antibiotics, from chemicals released from bacteria.
Inhibiting the bacterial cell wall synthesis.
Ceftriaxone is a 2-aminothiazolyl methoxylmino third-generation cephalosporin derivative. Ceftriaxone, a bactericidal antimicrobial, inhibits bacterial cell wall synthesis of actively dividing cells by binding to one or more penicillin-binding proteins (PBPs). These proteins are associated with the bacterial cell membrane and probably serve in synthesis. The result is the formation of a defective cell wall that is osmotically unstable. Bacterial species have a unique set of PBPs. The affinity pattern of ceftriaxone for the PBPs for different bacterial species affects the drug’s antimicrobial spectrum of activity.
It is also felt that cephalosporins, as well as penicillins, may increase the breakdown of the cell wall of the bacteria by decreasing the availability of an inhibitor of murein hydrolase, an enzyme involved in cell division. If unimposed, this enzyme can destroy the integrity of the cell wall.
Sulbactam does not possess any useful antibacterial activity, except against Neisseriaceae and Acinetobacter. As Sulbactam also binds with some penicillin-binding proteins, sensitive strains are also often rendered more susceptible to Sulbactam/Ceftriaxone than to Ceftriaxone alone. The combination of Sulbactam and Ceftriaxone is active against all organisms sensitive to ceftriaxone.
Infections caused by pathogens sensitive to Ceftriaxone & Sulbactam for Injection, e.g.:
- Abdominal infections (peritonitis, infections of the biliary and gastrointestinal tracts)
- Infections of the bones, joints, soft tissue, skin and of wounds
- Infections in patients with impaired defense mechanisms
- Renal and urinary tract infections
- Respiratory tract infections, particularly pneumonia, and ear, nose and throat infections
- Genital infections, including gonorrhea.
- Perioperative prophylaxis of infections.
- Considerations should be given to official guidance on the appropriate use of antibacterial agents.
Posology and Method of Administration
The recommended adult dosage is 1.5 g (1 g Ceftriaxone as the sodium salt plus 0.5 g Sulbactam as the sodium salt) to 3 g (2 g Ceftriaxone as the sodium salt plus 1 g Sulbactam as the sodium salt) every six hours.
This 1.5 to 3 g range represents the total of Ceftriaxone content plus the Sulbactam content and corresponds to a range of 1 g Ceftriaxone /0.5 g Sulbactam to 2 g Ceftriaxone /1 g sulbactam. The total dose of Sulbactam should not exceed 4 grams per day.
Neonates, infants and children up to 12 years: The following dosage schedules are recommended for once daily administration. Neonates (up to 14 days): 20 to 50 mg/kg bodyweight once daily. The daily dose should not exceed 50 mg/kg. It is not necessary to differentiate between premature and term infants. Infants and children (15 days to 12 years): 20 to 80 mg/kg once daily. For children with bodyweights of 50 kg or more, the usual adult dosage should be used. Intravenous doses of NLT 50 mg/kg bodyweight should be given by infusion over at least 30 minutes.
Reconstitution or the preparation for use: Dissolve the contents in 10 ml of sterile water for injection USP provided with this vial & Inject slowly within 3 to 5 minutes. The reconstituted solution should be used immediately after preparation.
Method of administration: Intramuscular Injection/ slow Intravenous Injection.
Ceftriaxone Injection is contraindicated in patients with known hypersensitivity to cephalosporin antibiotics. In patients hypersensitive to penicillin, consider the possibility of allergic cross reactions. The use of Sulbactamis contraindicated in individuals with a history of hypersensitivity reactions to any of the penicillins.
Special Warnings and Special Precautions for Use
This product should be given cautiously to penicillin-sensitive patients. Serious acute hypersensitivity reactions may require the use of subcutaneous epinephrine and other emergency measures. Clostridium difficile associated diarrhea has been reported with nearly all antibacterial agents, including ceftriaxone/Sulbactam, and may range in severity from mild to life-threatening.
Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. An immune mediated hemolytic anemia has been observed in patients receiving cephalosporin class anti-bacterial including Ceftriaxone. If a patient develops anemia while on ceftriaxone, the diagnosis of a cephalosporin associated anemia should be considered and ceftriaxone stopped until the etiology is determined.
Although transient elevations of BUN and serum creatinine have been observed, at the recommended dosages, the nephrotoxic potential of ceftriaxone/ Sulbactam is similar to that of other cephalosporins.
Alterations in prothrombin times have occurred infrequently in patients treated with ceftriaxone/Sulbactam. Patients with impaired vitamin K synthesis or low vitamin K stores (eg, chronic hepatic disease and malnutrition) may require monitoring of prothrombin time during Ceftriaxone and Sulbactam treatment. It should also be prescribed with caution in individuals with a history of gastrointestinal disease, especially colitis. There have been reports of sonographic abnormalities in the gall bladder of patients treated with ceftriaxone/Sulbactam; some of these patients also had symptoms of gall bladder disease.
Interaction with Other Medicinal Products and Other Forms of Interaction
Calcium-containing diluents, such as Ringer’s solution or Hartmann’s solution, should not be used to reconstitute Rocephin vials or to further dilute a reconstituted vial for intravenous administration because a precipitate can form. Precipitation of ceftriaxonecalcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same intravenous administration line. Ceftriaxone must not be administered simultaneously with calcium-containing intravenous 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. In vitro studies using adult and neonatal plasma from umbilical cord blood demonstrated that neonates have an increased risk of precipitation of ceftriaxone-calcium.
Concomitant use with oral anticoagulants may increase the anti-vitamin K effect and the risk of bleeding. It is recommended that the International Normalised Ratio (INR) is monitored frequently and the posology of the anti-vitamin K drug adjusted accordingly, both during and after treatment with ceftriaxone.
There is conflicting evidence regarding a potential increase in renal toxicity of aminoglycosides when used with cephalosporins. The recommended monitoring of aminoglycoside levels (and renal function) in clinical practice should be closely adhered to in such cases.
In an in-vitro study antagonistic effects have been observed with the combination of chloramphenicol and ceftriaxone. The clinical relevance of this finding is unknown.
There have been no reports of an interaction between ceftriaxone and oral calciumcontaining products or interaction between intramuscular ceftriaxone and calciumcontaining products (intravenous or oral).
In patients treated with ceftriaxone, the Coombs’ test may lead to false-positive test results.
Ceftriaxone, like other antibiotics, may result in false-positive tests for galactosaemia.
Likewise, non-enzymatic methods for glucose determination in urine may yield falsepositive results. For this reason, glucose level determination in urine during therapy with ceftriaxone should be carried out enzymatically.
No impairment of renal function has been observed after concurrent administration of largedoses of ceftriaxone and potent diuretics (e.g. furosemide).
Simultaneous administration of probenecid does not reduce the elimination of ceftriaxone.
Fertility, pregnancy and lactation
Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).
Lactation: Caution when used during lactation.
Fertility: Reproductive studies have shown no evidence of adverse effects on male or female fertility.
Effects on Ability to Drive and Use Machines
If you experience drowsiness, dizziness, hypotension or a headache as side-effects when using Ceftriaxone SulbactamInjection medicine then it may not be safe to drive a vehicle or operate heavy machinery. One should not drive a vehicle if using the medicine makes you drowsy, dizzy or lowers your blood-pressure extensively.
Pharmacists also advise patients not to drink alcohol with medicines as alcohol intensifies drowsiness side-effects. Please check for these effects on your body when using Ceftriaxone SulbactamInjection. Always consult with your doctor for recommendations specific to your body and health conditions.
The most frequently reported adverse reactions for ceftriaxone are eosinophilia, leucopenia, thrombocytopenia, diarrhoea, rash, and hepatic enzymes increased.
Symptoms: In the case of Ceftriaxone overdose nausea, vomiting, diarrhoea, can occur. Ceftriaxone concentration cannot be reduced by haemodialysis or peritoneal dialysis.
Treatment: There is no specific antidote. Treatment is symptomatic.
