Study Notes
Antimicrobial Agents
- Antimicrobial agents are substances that eliminate disease-causing microorganisms in humans.
- They can be synthetic, like sulfonamides, or derived from living organisms, like penicillins.
Antibacterial Agents
- Antibacterial agents target bacteria specifically.
- Different classes of antibacterial agents exist for treating bacterial infections.
Aminoglycosides
- Aminoglycosides work by inhibiting bacterial protein synthesis, killing bacteria.
- Used to treat Gram-negative bacterial infections.
- These infections can include urinary tract infections, meningitis, wound infections, and life-threatening sepsis.
- Aminoglycosides are a standard treatment for hospital-acquired (nosocomial) infections caused by specific Gram-negative bacteria like Acinetobacter, Citrobacter, Enterobacter, Escherichia coli, Kleibsiella, Providencia, Pseudomonas, Salmonella, and Shigella.
- Specific aminoglycoside agents include amikacin, gentamicin, kanamycin, neomycin, netilmicin, streptomycin, and tobramycin.
