Ceftobiprole, sold under the brand name Zevtera among others, is a fifth-generation[7]cephalosporin antibacterial used for the treatment of hospital-acquired pneumonia (excluding ventilator-associated pneumonia) and community-acquired pneumonia. It is marketed by Basilea Pharmaceutica under the brand names Zevtera and Mabelio.[8][9][10][11][12][13] Like other cephalosporins, ceftobiprole exerts its antibacterial activity by binding to important penicillin-binding proteins and inhibiting their transpeptidase activity which is essential for the synthesis of bacterial cell walls. Ceftobiprole has high affinity for penicillin-binding protein 2a of methicillin-resistant Staphylococcus aureus strains and retains its activity against strains that express divergent mecA gene homologues (mecC or mecALGA251). Ceftobiprole also binds to penicillin-binding protein 2b in Streptococcus pneumoniae (penicillin-intermediate), to penicillin-binding protein 2x in Streptococcus pneumoniae (penicillin-resistant), and to penicillin-binding protein 5 in Enterococcus faecalis.[14]
For adults with Staphylococcus aureus bloodstream infections (bacteremia), the most common side effects include anemia, nausea, low levels of potassium in the blood (hypokalemia), vomiting, diarrhea, increased levels of certain liver tests (hepatic enzymes and bilirubin), increased blood creatinine, high blood pressure, low white blood cell count (leukopenia), fever, abdominal pain, fungal infection, headache and shortness of breath (dyspnea).[15] For adults with acute bacterial skin and skin structure infections, the most common side effects include nausea, diarrhea, headache, injection site reaction, increased levels of hepatic enzymes, rash, vomiting and altered taste (dysgeusia).[15] For adults with community-acquired bacterial pneumonia, the most common side effects include nausea, increased levels of hepatic enzymes, vomiting, diarrhea, headache, rash, insomnia, abdominal pain, vein inflammation (phlebitis), high blood pressure and dizziness.[15] For children with community-acquired bacterial pneumonia, the most common side effects include vomiting, headache, increased levels of hepatic enzymes, diarrhea, infusion site reaction, vein inflammation (phlebitis) and fever.[15]
Ceftobiprole medocaril was approved for medical use in the United States in April 2024.[15][16]
