Critical care antibiotics are used to manage severe infections in critically ill patients. These infections can be life-threatening and require prompt and effective treatment. Here are some common classes and examples of antibiotics used in critical care:

Beta-Lactams:

Penicillins (e.g., Piperacillin-Tazobactam, Ampicillin)
Cephalosporins (e.g., Ceftriaxone, Cefepime)
Carbapenems (e.g., Imipenem, Meropenem)
Monobactams (e.g., Aztreonam)
Macrolides:

Azithromycin
Clarithromycin
Fluoroquinolones:

Levofloxacin
Ciprofloxacin
Aminoglycosides:

Gentamicin
Tobramycin
Glycopeptides:

Vancomycin
Teicoplanin
Lincosamides:

Clindamycin
Oxazolidinones:

Linezolid
Polymyxins:

Colistin (Polymyxin E)
The choice of antibiotic depends on the infection’s type, severity, the patient’s condition, and local resistance patterns. Broad-spectrum antibiotics are often used initially until specific pathogens are identified, after which therapy can be adjusted.
