Antibiotic Drug
An antibiotic drug is a medication that is used to treat infections caused by bacteria or other microorganisms. Antibiotics work by killing or inhibiting the growth of the infecting microorganisms.
Characteristics of Antibiotics:
- Antibacterial: Specifically targets bacteria without harming host cells.
- Selective: Generally targets specific types of bacteria, preventing broad-spectrum damage to the microbiome.
- Bacteriostatic: Inhibits bacterial growth without killing them.
- Bactericidal: Kills bacteria outright.
- Narrow-spectrum: Effective against a limited range of bacteria.
- Broad-spectrum: Effective against a wide range of bacteria.
Classes of Antibiotics:
There are numerous classes of antibiotics with different mechanisms of action and target organisms. Some common classes include:
- Penicillins: Inhibit bacterial cell wall synthesis.
- Cephalosporins: Similar to penicillins but have a broader antimicrobial spectrum.
- Macrolides: Inhibit bacterial protein synthesis.
- Tetracyclines: Inhibit bacterial protein synthesis and bone growth in children.
- Aminoglycosides: Damage bacterial cell membranes and inhibit protein synthesis.
- Quinolones: Inhibit bacterial DNA synthesis.
- Sulfonamides: Inhibit bacterial folic acid synthesis.
- Nitrofurans: Damage bacterial DNA and inhibit cellular metabolism.
Uses of Antibiotics:
Antibiotics are commonly used to treat infections caused by bacteria, including:
- Pneumonia
- Urinary tract infections (UTIs)
- Skin infections
- Sepsis
- Meningitis
- Tuberculosis
Importance of Antibiotic Stewardship:
Excessive or inappropriate use of antibiotics can lead to the development of antibiotic resistance. This can make it difficult or impossible to treat bacterial infections in the future. Therefore, it is important to use antibiotics only when necessary and as directed by healthcare professionals.
