Which of the following statements accurately describes a key difference between aminoglycosides and tetracyclines?
Which of the following statements accurately describes a key difference between aminoglycosides and tetracyclines?
- Aminoglycosides are typically used to treat fungal infections, while tetracyclines are used for bacterial infections.
- Tetracyclines primarily function by disrupting the bacterial cell wall, while aminoglycosides inhibit protein synthesis.
- Tetracyclines are effective against aerobic gram-negative bacteria, while aminoglycosides are effective against anaerobic gram-positive bacteria.
- Aminoglycosides are known for their potential toxicity and require careful monitoring, while tetracyclines are not recommended for children or pregnant women. (correct)

Tetracyclines
Tetracyclines
Class of antibiotics that generally prevent protein synthesis in bacteria, leading to growth inhibition between 1950-1960.
Doxycycline uses
Doxycycline uses
Useful against both gram-negative and gram-positive organisms. Can treat gonorrhea, chlamydia, and anthrax.
Minocycline
Minocycline
A type of tetracycline that is useful against upper and lower respiratory tract infections.

Study Notes
- Tetracyclines were introduced in 1950-1960 and prevent protein synthesis
- Doxycycline is effective against Gram-negative and Gram-positive bacteria
- It is also used to treat gonorrhea, chlamydia, and anthrax
- Minocycline is used for community-acquired pneumonia (CAP)
- Tetracycline is not recommended for children or pregnant women because it prevents protein synthesis
Macrolides
- Erythromycin can be administered PO or IV
- Clarithromycin is effective against infections resistant to penicillins and inhibits the reproduction of microorganisms by inhibiting protein synthesis
- Azithromycin can be bactericidal or bacteriostatic and is effective at treating many infections
Aminoglycosides
- Aminoglycosides are very toxic, it's important to monitor blood levels and kidney function
- Amikacin and Paromomycin are effective against aerobic Gram-negative bacteria, including Pseudomonas and Tuberculosis
- Gentamicin and Tobramycin are also Aminoglycosides
- Kanamycin and Neomycin are Aminoglycosides used topically, IV, or as eye/ear drops
Quinolones
- Quinolones are anti-infectives
- Ciprofloxacin is bacteriostatic and is an FDA-DC medication
- Ofloxacin can be administered IV, PO, or as eye drops and is used to treat UTIs
- Side effects of Ofloxacin may include dizziness, confusion, tremors, hallucinations, depression, allergic reactions, pain, and muscle aches
