Cephalosporins are a type of antibiotic. Antibiotics are medications that treat bacterial infections. There are many types, often called classes, of antibiotics available. Cephalosporins are a type of beta-lactam antibiotic. Cephalosporins kill bacteria and function similarly to penicillins. They bind to and inhibit the action of enzymes involved in the production of peptidoglycan, an essential component of the bacterial cell wall. They are known as broad-spectrum antibiotics because they are effective against a wide range of bacteria. Cephalosporins tablets are available in multiple dosages of 250mg, 500mg, and 750mg.
