Study Notes
Tetracyclines Overview
- Class of antibiotics effective against both gram-negative and gram-positive bacteria
- Function by inhibiting protein synthesis in bacterial cells
Importance of Protein Synthesis
- Stopping protein synthesis prevents bacterial cell division and replication
Uses of Tetracyclines
- Alternative treatment for patients allergic to penicillins
- Indicated for certain venereal diseases, UTIs, upper respiratory infections, pneumonia, and meningitis
Effectiveness
- Particularly effective for skin infections (acne), rickettsial infections, and mycoplasmic infections
Impact on Tooth Development
- Administration during tooth development (from second half of pregnancy to age 8) can lead to enamel hypoplasia and permanent tooth staining
Breast Milk Secretion
- Tetracyclines are secreted in breast milk, which might pose risks for nursing infants
Therapeutic Outcome
- Aims for the elimination of bacterial infections in patients
Premedication Assessment
- Obtain baseline assessments: presenting symptoms, temperature, pulse, respirations, blood pressure, and hydration status
- Assess for gastric symptoms, allergies, and complete necessary lab studies before therapy
Availability
- Tetracyclines are available in oral (PO) form
Common Adverse Effects
- Adverse effects include nausea, vomiting, abdominal cramps, diarrhea, and photosensitivity
Interaction with Warfarin
- Tetracyclines may enhance the anticoagulant effects of warfarin, increasing bleeding risk
- Monitor for signs of bleeding such as petechiae, ecchymoses, nosebleeds, bleeding gums, and dark or bloody stools
Administration Guidelines
- Administer tetracycline products at least 1 hour before or 2 hours after ingestion of substances that decrease absorption, including:
- Iron
- Calcium-containing foods
- Calcium supplements
- Aluminum and magnesium preparations
Contraindications for Co-administration
- Avoid administering tetracycline within 2 hours of taking didanosine or pediatric powder for oral solution due to absorption inhibition caused by antacids in these products
