Study Notes

Antibiotic Mechanisms of Action and Adverse Effects

Amoxicillin/Clavulanate: Inhibits bacterial cell wall synthesis and protects against beta-lactamase.
Ciprofloxacin: Associated with QT prolongation as an adverse effect.
Levofloxacin: Myasthenia gravis is a contraindication for its use.
Azithromycin: Primarily used to treat respiratory tract infections.
Piperacillin/Tazobactam: A beta-lactam/beta-lactamase inhibitor combination.
Trimethoprim/Sulfamethoxazole: Nephrotoxicity is a potential adverse effect.
Ceftriaxone: Inhibits bacterial cell wall synthesis.
Metronidazole: Effective against anaerobic bacteria.
Vancomycin (oral): Primarily used for Clostridium difficile infections.
Rifaximin: Inhibits bacterial RNA polymerase.

Additional Antibiotic Information

Metronidazole: Adverse effect is metallic taste.
Rifaximin: Used to treat hepatic encephalopathy.
Fluoroquinolones (e.g., ciprofloxacin): Black-box warning for tendon rupture.
Vancomycin (IV): Nephrotoxicity is a significant adverse effect.
Vancomycin: Requires monitoring of trough levels.
Metronidazole: Commonly interacts with warfarin, increasing its toxicity.
Fidaxomicin: Adverse effect is anemia.
Piperacillin/Tazobactam: Mechanism is inhibiting bacterial cell wall synthesis and beta-lactamase.
