Aztreonam
Aztreonam is a vital monobactam antibiotic, a specialized subclass of beta-lactam antibiotics, primarily targeting Gram-negative aerobic bacteria. It works by inhibiting bacterial cell wall synthesis, a critical process for bacterial survival. This targeted mechanism makes it an effective treatment for severe infections across various bodily systems.
- Aztreonam mechanism of action: Its primary function is to inhibit the synthesis of bacterial cell walls, leading to bacterial death.
- Aztreonam side effects: While generally well-tolerated, potential side effects include injection site discomfort, diarrhea, nausea, vomiting, and rash.
- Aztreonam gram-negative infections: It is particularly effective against infections caused by Gram-negative bacteria, including notorious pathogens like Pseudomonas aeruginosa.
- Aztreonam beta-lactam allergy: Aztreonam is often a preferred choice for patients with allergies to other beta-lactam antibiotics, due to its low cross-reactivity, although caution is advised for severe allergies to ceftazidime or cefiderocol.
Key Advantages
Targeted Efficacy
Aztreonam's selective action against Gram-negative bacteria minimizes disruption to beneficial flora, reducing the risk of secondary infections.
Hypersensitivity Profile
Its unique structure offers a favorable safety profile for patients with allergies to other beta-lactams, making it a crucial alternative.
Versatile Administration
Available for both injection and inhalation, Aztreonam provides flexibility in treating various infection types and patient needs.
Key Applications
Respiratory Tract Infections
Effective in treating bacterial pneumonia and other lower respiratory tract infections caused by susceptible Gram-negative bacteria.
Urinary Tract Infections
A reliable option for managing bacterial UTIs, particularly when caused by Gram-negative pathogens resistant to other agents.
Bloodstream Infections
Used in the treatment of sepsis and bacteremia originating from Gram-negative bacterial infections.
Skin and Soft Tissue Infections
Effective for treating infections of the skin and soft tissues caused by susceptible Gram-negative bacteria.
