Cephalosporins are a group of beta-lactam antibiotics derived from the fungus Cephalosporium acremonium. They are widely used in clinical medicine due to their broad spectrum of activity against both Gram-positive and Gram-negative bacteria. Cephalosporins are typically administered orally or intravenously and are effective against a variety of bacterial infections, including respiratory tract infections, skin and soft tissue infections, and urinary tract infections.

The cephalosporin class includes several generations, each with improved properties over the previous one. First-generation cephalosporins, such as cephalexin and cephalothin, have a limited spectrum of activity and are often used for mild to moderate infections. Second-generation cephalosporins, like cefuroxime and cefotaxime, have a broader spectrum and are used for more severe infections. Third-generation cephalosporins, such as ceftriaxone and cefotetan, have even broader spectra and are often used for serious infections, including those caused by multidrug-resistant bacteria. Fourth-generation cephalosporins, like cefepime, have an extended spectrum and are used for severe infections, including those caused by Pseudomonas aeruginosa.

Cephalosporins work by inhibiting the synthesis of peptidoglycan, a component of the bacterial cell wall. This leads to cell lysis and death. However, the use of cephalosporins is limited by the development of bacterial resistance. To combat this, cephalosporins are often used in combination with other antibiotics or with non-antibiotic drugs that enhance their effectiveness. Additionally, the responsible use of cephalosporins, including appropriate dosing and duration of treatment, is crucial to minimize the risk of resistance development.
