What class of antibiotics does Ceftriaxone belong to?

Ceftriaxone is classified as a third-generation cephalosporin antibiotic. This classification is important because third-generation cephalosporins, like Ceftriaxone, possess a broader spectrum of activity compared to earlier generations. They are particularly effective against a wide range of gram-negative bacteria, including some strains that are resistant to other antibiotics.

Additionally, third-generation cephalosporins are known for their ability to penetrate the central nervous system, making them effective for treating infections such as meningitis. Ceftriaxone is commonly used in clinical settings to treat various infections, including those caused by Streptococcus pneumoniae and certain strains of Escherichia coli.

In contrast, first-generation and second-generation cephalosporins have a more limited spectrum of activity and are typically more effective against gram-positive bacteria than gram-negative. Fourth-generation cephalosporins further expand the spectrum to include more resistant strains but are classified separately due to their distinct features and clinical uses.
