Study Notes
- Broad spectrum antibiotics include tetracyclines.
- Narrow spectrum antibiotics include biosynthetic penicillins.
- Polymyxins act only on gram-negative flora.
- Monobactams are beta lactam antibiotics.
- Beta-lactam antibiotics interfere with the synthesis of the bacterial cell wall.
- Biosynthetic penicillins include benzylpenicillin sodium salt.
- The antibacterial effect of ampicillin is reinforced under the influence of oxacillin.
- Azithromycin is an antibiotic from the azalide group.
- Ampicillin has a wide spectrum of antimicrobial activity, is acid resistant, and not resistant to penicillinase.
- Benzylpenicillin preparations are not stable in an acid environment.
- Benzylpenicillin sodium salt acts mainly on gram-positive flora, is not resistant to penicillinase, is not stable in an acidic environment, and its duration of action is 3-4 hours.
- Benzathine benzylpenicillin acts mainly on gram-positive flora, is not resistant to penicillinase, is not stable in an acidic environment, and its duration of action is about 4 weeks.
- Ampicillin is a semi-synthetic penicillin with a wide spectrum of action.
- Oxacillin is a semi-synthetic penicillin, resistant to penicillinase, stable in an acidic environment, and acts mainly on gram-positive flora.
- Benzylpenicillin preparations are used for syphilis.
- Bicillins act longer, in contrast to benzylpenicillin sodium salt.
- Tetracyclines causes liver dysfunction.
