Which of the following is a second generation cephalosporin?

Cefuroxime is classified as a second-generation cephalosporin. This class of antibiotics is known for being effective against a broader range of Gram-negative bacteria compared to first-generation cephalosporins while still maintaining efficacy against Gram-positive organisms. Cefuroxime offers enhanced activity against organisms such as Haemophilus influenzae and Escherichia coli, making it useful in treating respiratory tract infections and other bacterial infections.

In contrast, cefdinir and ceftazidime are classified as third-generation cephalosporins, with cefdinir targeting a variety of bacterial infections with good oral bioavailability and ceftazidime having specific activity against Pseudomonas aeruginosa. Cefepime is a fourth-generation cephalosporin, which provides broad-spectrum coverage, including more resistant strains of bacteria. This progression in classification reflects a change in the bacteria that each generation effectively targets, as well as the introduction of new treatment capabilities.
