Study Notes
Types of Antibiotics
- Broad-spectrum antibiotics target a wide range of bacteria, including both Gram-positive and Gram-negative types.
Antibiotic Classes
- Beta-lactam antibiotics include agents that inhibit cell wall synthesis, crucial for bacterial structural integrity.
Ideal Antimicrobial Properties
- Ideally, antimicrobial agents should have a selective toxicity, minimal side effects on host, effective against pathogens, stability in body fluids, and an ability to penetrate tissues.
Penicillin Types
- Penicillin V is less acid labile, allowing for oral administration without significant degradation.
Benzylpenicillin Administration
- Benzylpenicillin procaine salt is used for prolonged action through intramuscular administration, enhancing the antibiotic’s duration in the system.
Spectrum of Benzylpenicillin
- Benzylpenicillin is effective against a narrow spectrum of bacteria due to its specific mechanism targeting mainly Gram-positive organisms and a select few Gram-negative bacteria.
