## Mechanism of action

✂**MRSA PBP2a and other PBPs**Ceftobiprole

ⓘ The figure shows methicillin-resistant Staphylococcus aureus PBP2a acylated by ceftobiprole in the active site.

**Target in 3D:** MRSA PBP2a and other PBPs. PDB structure 4DKI (RCSB PDB, public domain). [View the structure at RCSB PDB](https://www.rcsb.org/structure/4DKI) · Drag to rotate · pinch to zoom

Ceftobiprole medocaril is a prodrug rapidly converted to ceftobiprole. It acylates the PBPs, including PBP2a, which makes S. aureus methicillin-resistant and which other cephalosporins barely inhibit. Against gram-positives it resembles ceftaroline; against gram-negatives, including Pseudomonas, it resembles ceftazidime.

- The medocaril prodrug releases ceftobiprole in the blood
- Acylates MRSA PBP2a and other PBPs
- Wall cross-linking halts
- The bacterium lyses (bactericidal)

## Indications

- Certain bacterial pneumonias
- Certain bloodstream infections (bacteraemia)
- Certain bacterial skin infections

## Adverse effects

### Common

- Nausea, vomiting, diarrhoea and abdominal pain
- Headache and insomnia
- Unusual taste in the mouth
- Infusion-site reactions

### Serious (rare, important)

- Seizures, above all with epilepsy or kidney disease
- Severe allergic reactions
- Clostridioides difficile diarrhoea

## Contraindications

- Allergy to ceftobiprole or other cephalosporins

## Key interactions

**Laboratory tests**
It may alter some results; the laboratory is told.

## What is monitored

- Kidney function
- Neurological status in people with epilepsy or kidney failure
- Follow-up blood cultures in bacteraemia

## Administration and safety

- Slow IV infusion of about 2 hours
- Name looks like ceftaroline and ceftazidime: the label is checked

## Nursing care

- Ask about beta-lactam allergy, epilepsy and kidney disease
- Watch for seizures or changes in consciousness
- Watch the infusion site
- Ask the patient to report severe diarrhoea

## Pharmacokinetics

**Absorption**
IV only.

**Metabolism**
The prodrug is rapidly converted to active ceftobiprole.

**Elimination**
Renal, like ceftaroline.

## Memory aid

«CefTOBIprole, TOtal in One»: MRSA through PBP2a (like ceftaroline) and Pseudomonas (like ceftazidime) in the same molecule.

## Test yourself

Think of the answer, then tap the question to see it.

## Which protein lets ceftobiprole act against MRSA?

PBP2a, encoded by mecA, which ceftobiprole acylates and other cephalosporins barely inhibit.

## How does ceftobiprole's spectrum differ from ceftaroline's?

Besides MRSA, it covers Pseudomonas aeruginosa, with a gram-negative spectrum similar to ceftazidime.

## Which neurological adverse effect is watched with ceftobiprole?

Seizures, above all in people with epilepsy or kidney disease.
