What is 3rd generation cephalosporins?
Third-generation cephalosporins are broad-spectrum antimicrobial agents useful in a variety of clinical situations. No one cephalosporin is appropriate for all infectious disease problems. Cefotaxime and ceftizoxime have the best gram-positive coverage of the third-generation agents.
Are 4th generation cephalosporins broad-spectrum?
They bind to and block the activity of enzymes responsible for making peptidoglycan, an important component of the bacterial cell wall. They are called broad-spectrum antibiotics because they are effective against a wide range of bacteria.
