Phase
4

This third-generation cephalosporin antibiotic with unusual oxacephem structure had good activity against gram-negative bacteria and anaerobes but was associated with serious bleeding problems due to interference with vitamin K-dependent clotting factors. It has been largely replaced by safer cephalosporins and other antibiotics.
