Key Anti-Infective Drug Classes: A Quizlet-Style Breakdown

This section mirrors the format you'd expect from Quizlet, presenting key information in a concise and memorable way. Think of each point as a flashcard, ready to be reviewed and internalized.

1. Antibiotics:

• Mechanism of Action: Interfere with bacterial cell wall synthesis, protein synthesis, nucleic acid synthesis, or metabolic pathways.
• Key Classes:
  • Penicillins (e.g., Amoxicillin, Penicillin G): Beta-lactam antibiotics that inhibit cell wall synthesis. Watch for allergic reactions!
  • Cephalosporins (e.g., Cefazolin, Ceftriaxone): Also beta-lactams, structurally similar to penicillins; broader spectrum of activity. Cross-allergenicity with penicillins is a concern.
  • Tetracyclines (e.g., Doxycycline, Tetracycline): Inhibit protein synthesis. Avoid in pregnancy and young children due to tooth discoloration.
  • Macrolides (e.g., Erythromycin, Azithromycin): Inhibit protein synthesis. Often used as alternatives to penicillins.
  • Aminoglycosides (e.g., Gentamicin, Tobramycin): Inhibit protein synthesis; potent but nephrotoxic and ototoxic. Monitor serum levels closely.
  • Fluoroquinolones (e.g., Ciprofloxacin, Levofloxacin): Inhibit DNA gyrase and topoisomerase IV; broad-spectrum activity. Can cause tendon rupture, especially in older adults.
  • Sulfonamides (e.g., Sulfamethoxazole): Inhibit folic acid synthesis. Often combined with trimethoprim (e.g., Bactrim).
• Nursing Considerations: Monitor for allergic reactions (rash, itching, swelling), superinfections (e.g., C. difficile), and organ toxicity (kidneys, liver, ears). Always assess for allergies and obtain cultures before initiating therapy.
• Patient Education: Emphasize the importance of completing the entire course of antibiotics, even if symptoms improve. Discuss potential side effects and when to contact healthcare providers.

2. Antifungal Medications:

• Mechanism of Action: Disrupt fungal cell membranes or inhibit fungal enzyme activity.
• Key Classes:
  • Azoles (e.g., Fluconazole, Ketoconazole): Inhibit ergosterol synthesis. Can interact with many other medications.
  • Echinocandins (e.g., Caspofungin): Inhibit cell wall synthesis. Generally well-tolerated but can cause infusion-related reactions.
  • Polyenes (e.g., Amphotericin B): Bind to ergosterol, causing cell membrane damage. Known for significant nephrotoxicity.
• Nursing Considerations: Monitor for liver function abnormalities, renal function, and infusion reactions (especially with amphotericin B). Assess for signs of infection resolution.
• Patient Education: Explain the duration of therapy and the importance of adherence. Address potential side effects, including liver and kidney problems.

3. Antiviral Medications:

• Mechanism of Action: Inhibit viral replication by targeting specific viral enzymes or processes.
• Key Classes:
  • Acyclovir (for Herpes viruses): Inhibits viral DNA polymerase.
  • Oseltamivir (Tamiflu, for Influenza): Neuraminidase inhibitor, preventing viral release.
  • Antiretroviral therapy (ART, for HIV): A combination of drugs targeting different stages of the HIV life cycle. (e.g., Nucleoside/Nucleotide reverse transcriptase inhibitors (NRTIs), Non-nucleoside reverse transcriptase inhibitors (NNRTIs), Protease inhibitors (PIs), Integrase strand transfer inhibitors (INSTIs), Entry inhibitors).
• Nursing Considerations: Monitor for drug interactions, organ toxicity, and virologic response. Patient education is crucial for adherence to complex ART regimens.
• Patient Education: Emphasis on adherence to medication regimens, regular monitoring of viral load, and lifestyle modifications to support immune function. Importance of preventative measures to avoid infection.

4. Antiparasitic Medications:

• Mechanism of Action: Varies widely depending on the parasite and the drug. May interfere with metabolic pathways or neuromuscular function.
• Key Classes:
  • Metronidazole (Flagyl): Effective against several anaerobic bacteria and protozoa. Avoid alcohol consumption.
  • Ivermectin: Effective against several parasitic worms and some arthropods.
  • Quinine: Used for malaria treatment. Has significant side effects.
• Nursing Considerations: Monitor for gastrointestinal distress, neurotoxicity, and allergic reactions. Patient education is critical, focusing on safe medication use and prevention of re-infection.
• Patient Education: Importance of proper hygiene, safe food and water practices, and avoiding insect bites. Complete the entire course of medication even if symptoms improve.

Beyond the Basics: Advanced Concepts & Nursing Implications

This section delves into more nuanced aspects of infection management pharmacology, focusing on crucial nursing considerations and patient education strategies.

1. Antimicrobial Stewardship: The responsible use of antimicrobials is paramount in preventing the development and spread of antibiotic-resistant organisms. Nurses play a key role in:

• Promoting appropriate antibiotic prescribing: Advocating for culture and sensitivity testing before initiating therapy.
• Monitoring for therapeutic efficacy and adverse effects: Closely observing patients for signs of improvement or worsening infection and reporting any adverse effects promptly.
• Educating patients on appropriate antibiotic use: Emphasizing the importance of completing the entire course of antibiotics and avoiding unnecessary antibiotic use.

2. Understanding Antimicrobial Resistance: The rise of antibiotic-resistant bacteria is a serious global health threat. Nurses must be aware of:

• Risk factors for developing resistant infections: Previous antibiotic use, hospitalization, immunocompromised status.
• Strategies to prevent the spread of resistant organisms: Strict adherence to infection control protocols, hand hygiene, and appropriate isolation precautions.
• The importance of infection prevention and control: Emphasis on preventing infections in the first place to minimize the need for antibiotics.

3. Patient-Specific Considerations: Pharmacological decisions must always consider individual patient factors:

• Age: Drug dosage and choice may vary based on age and renal or hepatic function.
• Pregnancy and lactation: Many medications are contraindicated or require careful monitoring during pregnancy and lactation.
• Renal and hepatic function: Drug metabolism and excretion are significantly affected by kidney and liver function. Dosage adjustments are often necessary.
• Allergies and drug interactions: Thorough medication reconciliation and allergy assessment are vital to avoid adverse reactions and drug interactions.

4. Monitoring for Therapeutic Effectiveness and Adverse Effects: Continuous assessment is crucial:

• Clinical signs and symptoms: Monitor for improvement or worsening of infection, including fever, pain, inflammation, and laboratory values.
• Laboratory tests: Culture and sensitivity tests, complete blood count (CBC), renal and liver function tests.
• Adverse effects: Watch for signs and symptoms of organ toxicity, allergic reactions, and superinfections.

5. Patient Education: A Cornerstone of Care: Effective patient education is paramount:

• Medication administration: Provide clear instructions on how to take medications, including dosage, timing, and route of administration.
• Potential side effects: Educate patients about common and serious side effects and when to seek medical attention.
• Adherence to therapy: Emphasize the importance of completing the entire course of antibiotics even if symptoms improve.
• Lifestyle modifications: Advise patients on lifestyle changes that may improve their immune function and reduce the risk of infection.
• Infection prevention strategies: Teach patients about hand hygiene, safe food and water practices, and avoiding exposure to infectious agents.
