Study Notes
Antimicrobial Agents
- Antimicrobial agents are chemicals that eliminate pathogenic microorganisms in humans.
- These agents can be chemical, like sulfonamides, or derived from microorganisms, like penicillins.
Antibacterial Agents
- Antibacterial agents are antimicrobials specifically targeting bacteria.
- Aminoglycosides are a class of antibacterial agents acting by inhibiting bacterial protein synthesis.
- Aminoglycosides are used against Gram-negative microorganisms causing urinary tract infections, meningitis, wound infections, and life-threatening sepsis.
- Aminoglycosides are commonly used for treating hospital-acquired (nosocomial) Gram-negative infections caused by several bacterial species, including Acinetobacter, Citrobacter, Enterobacter, Escherichia coli, Kleibsiella, Providencia, Pseudomonas, Salmonella, and Shigella.
- Examples of aminoglycoside agents include amikacin, gentamicin, kanamycin, neomycin, netilmicin, streptomycin, and tobramycin.
