Cephalosporins are known to be an antibiotic, which is divided into several different drug classes. With each group of drugs, the way of use is also different, it is necessary to follow the doctor's instructions, do not arbitrarily use the drug without a doctor's prescription.

Cephalosporins are classified by generation based on the characteristics of their antibacterial action. The third generation cephalosporins are less effective against Gram-positive cocci than the first generation, but are much more effective against the Enterobacteriaceae family, including beta-lactamase-producing strains. However, the effect against Pseudomonas aeruginosa must be considered very carefully because of the wide variation in rates of resistance and antibiotic use across hospitals, communities and cities.
