How Do Nitroimidazoles Work?
Nitroimidazoles are antibiotics used to treat anaerobic bacterial infections, parasitic infections, and protozoal infections and prevent postoperative infections.
Nitroimidazoles work by disrupting the DNA of the susceptible bacteria and inhibiting the protein synthesis of the cell wall leading to cell death; they act as bactericidal and antimicrobial agents.
Nitroimidazoles are given orally as intravenous infusions and used for local applications in skin infections.
Nitroimidazoles should be used with caution in patients with a medical history of central nervous system disorders (seizures) and with blood dyscrasias (a disorder that affects blood and its components).
