Ceftriaxone, sold under the brand name Rocephin, is a third-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [4] These include middle ear infections, endocarditis, meningitis, pneumonia, bone and joint infections, intra-abdominal infections, skin infections, urinary tract infections, gonorrhea, and pelvic inflammatory disease.

β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Cefuroxime is active against many bacteria including susceptible strains of Staphylococci and Streptococci, as well as a range of gram negative organisms. [11] As with the other cephalosporins, it is susceptible to beta-lactamase, although as a second-generation variety, it is less so.
Second generation cephalosporins are more effective in treating Gram-negative bacilli compared to first generation cephalosporins, which have a greater coverage for Gram-positive cocci. Also, it has been reported that cefuroxime is resistant to hydrolysis by β-lactamases produced by Gram-negative bacteria. [4] Some medical uses are: [5] [6]
