Indications:Indicated in the treatment of UTI, lower respiratory tract infections, bacteremia, septicaemia, meningitis, abdominal infections and infections caused by pseudomonas species.
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.
Usual adult dose is 1-2g once a day or in divided doses. Should not exceed 4 g/day. 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.
