Axon is a 3rd generation broad-spectrum parenteral cephalosporin antibiotic. It has potent bactericidal activity against a wide range of Gram-positive and Gram-negative organisms. Axon like other cephalosporins and penicillins kills bacteria by interfering with the synthesis of the bacterial cell wall. Axon has a high degree of stability in the presence of beta lactamases. A remarkable feature of Axon is its relatively long plasma elimination half-life of about 6 to 9 hours, which makes single or once-daily dosage of the drug appropriate for most patients. Ceftriaxone is not metabolized in the body. About 40-65% of a dose of Ceftriaxone is excreted unchanged in the urine; the remainder is excreted in the bile and ultimately found in the feces as unchanged drug and microbiologically inactive compound. The drug is highly protein bound (95%).

9. Prevention of postoperative infections
10. Perioperative prophylaxis of infections associated with surgery
11. Typhoid fever.
Adult: By deep intramuscular injection, or by intravenous injection over at least 2-4 minutes, or by intravenous infusion, 1 g daily; 2-4 g daily in severe infections; intramuscular doses over 1 g divided between more than one site. Neonate: By intravenous infusion over 60 minutes, 20-50 mg/kg daily (max.50 mg/kg daily). Infant and child under 50 kg: by deep intramuscular injection or by intravenous injection over 2-4 minutes or by intravenous infusion, 20-50 mg/kg daily; up to 80 mg/kg daily in severe infections; doses of 50 mg/kg and over by intravenous infusion only; 50 kg and over, adult dose.
Uncomplicated gonorrhea: by deep intramuscular injection, 250 mg as a single dose. Surgical prophylaxis: by deep intramuscular injection or by intravenous injection over at least 2-4 minutes, 1 g at induction, Colorectal surgery: by deep intramuscular injection or by intravenous injection over at least 2-4 minutes or by intravenous infusion, 2 g at induction; intramuscular doses over 1 g divided between more than one site.
Duration of therapy: Continue for more than 2 days after signs and symptoms of infection have disappeared. Usual duration is 4 to 14 days; in complicated infections, longer therapy may be required.
Preparation of Solutions for Intramuscular/intravenous Injections:
For intramuscular injection: 250 mg or 500 mg Axon should be dissolved in 2 ml of 1% Lidocaine Injection USP or 1 g Axon in 3.5 ml of 1% Lidocaine Injection USP. For intravenous injection: 250 mg or 500 mg Axon should be dissolved in 5 ml of Water for Injection BP or 1 g Axon in 10 ml of Water for Injection BP or 2 g Axon in 20 ml of Water for Injection BP. The injection should be administered over 2-4 minutes, directly into the vein or via the tubing of an intravenous infusion. The use of freshly reconstituted solution is recommended. However, it maintains potency for at least 6 hours at room temperature or 24 hours at 5°C.
Ceftriaxone should not be given to patients with a history of hypersensitivity to cephalosporin antibiotics.
The admixture of beta-lactam antibacterials (penicillins and cephalosporins) and aminoglycosides may result in substantial mutual inactivation. If they are administered concurrently , they should be administered in separate sites. Do not mix them in the same intravenous bag or bottle.
Ceftriaxone is generally well tolerated. A few side effects such as gastro-intestinal effects including diarrhoea, nausea and vomiting, stomatitis & glossitis; cutaneous reactions including rash, pruritus, urticaria, oedema & erythema multiforme; hematologic reactions including eosinophilia, thrombocytopenia, leucopenia, anemia and neutropenia; hepatic reactions including elevations of SGOT or SGPT, bilirubinemia; CNS reactions including headache, hyperactivity, nervousness, sleep disturbances, confusion, hypertonia and dizziness were reported. Local phlebitis occurs rarely following intravenous administration but can be minimized by slow injections over 2-4 minutes.
No drug interactions have been observed with diuretics or with aminoglycosides.
Use in pregnancy: Its safety in human pregnancy has not been established. Therefore it should not be used in pregnancy unless absolutely indicated.
Use in nursing mother: Only minimal amount of Ceftriaxone is excreted in breast milk, so mother-receiving Ceftriaxone should not breast-feed. In severe renal impairment accompanied by hepatic insufficiency, dosage reduction is required.
