    Study Notes

    Tuberculosis (TB)

    • Rifapentine: contraindicated in patients with liver disease
    • Ethambutol: first bacteriostatic drug used to treat TB, causes optic neuritis in pediatric patients (younger than 13)
    • Other first-line drugs: Rifabutin, Pyrazinamide, Rifampin, Streptomycin
    • Second-line drugs: Bedaquiline (used for multidrug-resistant TB), Pretomanid (used for only pulmonary multidrug-resistant TB), Capreomycin, Cycloserine, Levofloxacin, Ethionamide, Oflaxacin, Kanamycin, Para-aminosalicylic acid (PAS)

    TB Infection and Diagnosis

    • Primary TB infection: first infectious episode

    • Purified protein derivatives (PPD) or Mantoux test: an injection given intradermally to detect exposure to TB organism
    • A positive result is indicated by induration (not erythema) at the site of injection

    Drug Therapy Considerations

    • Monitor patient closely during therapy
    • Major effects of drug therapy: reduction of cough, and therefore reduction of infectiousness
    • Normally occurs within 2 weeks
    • Treatment can take up to 2 years due to non-compliance and environmental factors
    • Patient education: therapy may last from 12 months to 2 years, take medications as ordered, and inform patient of importance of taking medications as prescribed

    Anti-Inflammatory Drugs

      • Allopurinol: used to prevent uric acid production and to prevent acute tumor lysis syndrome
      • Febuxostat: used to decrease uric acid production
      • Colchicine: used for short-term management of gout
      • Probenecid: inhibits the reabsorption of uric acid in the kidneys and thus increases the excretion of uric acid
    • Anticoagulant medications:
      • Warfarin: therapeutic range is 2-3, patient education: safe administration, prevention and management of bleeding, and when to contact the doctor
      • Heparin: unfractionated and low molecular weight, lab monitoring: aPTT, antidote: IV protamine sulfate
      • Antiplatelet medications: Aspirin, Clopidogrel, and Ticagrelor

    COPD (Chronic Obstructive Pulmonary Disease)

    • Definition: recurrent and reversible shortness of breath
    • Causes: bronchospasms, inflammation of the bronchial mucosa, edema of the bronchial mucosa, and production of viscous mucus
    • Short-acting beta agonists (SABAs):
      • Albuterol (Ventolin, ProAir): most commonly used, first line of defense in acute respiratory distress
      • Levalbuterol (Xopenex)
      • Terbutaline (Brethine)
      • Metproterenol (Alupent)
    • Long-acting beta agonists (LABAs):
      • Arformoterol (Brovana)
      • Formoterol (Foradil, Perforomist)
      • Salmeterol (Serevent)
      • Vilanterol in conjunction with fluticasone (Breo Ellipta)
      • Vilanterol in conjunction with the anticholinergic, umeclidinium (Anoro Ellipta)
    • Anticholinergics:
      • Ipratropium (Atrovent)
      • Tiotropium (Spiriva)
      • Aclidinium (Tudorza)
    • Xanthine derivatives: Theophylline
    • Corticosteroids:
      • Inhaled corticosteroids: Beclomethasone (Beclovent), Budesonide (pulmicort, turbuhaler), Ciclesonide (Omnaris), Flunisolide (Aerobid), Fluticasone (Flovent, Flonase)
      • Systemic corticosteroids: used to treat acute exacerbations or severe asthma

    Antibiotics

    • Sulfonamides: one of the first groups of antibiotics, often combined with another antibiotic
    • Beta-Lactam antibiotics: Penicillins, Cephalosporins, Carbapenems, Monobactams
    • Macrolides: Erythromycin (E-mycin), Azithromycin (Zithromax), Clarithromycin (Biaxin)
    • Tetracyclines: Demeclocyline, Oxytetracycline, Tetracycline
    • Aminoglycosides: Gentamicin, Neomycin, Tobramycin, Amikacin
    • Quinolones: Ciprofloxacin (Cipro), Norfloxacin (Noroxin), Levofloxacin (Levaquin), Moxifloxacin (Avelox), Gemifloxacin (Factive), Delfloxacin (Baxda)

    Antitubercular Drugs

    • First-line drugs: Isoniazid (INH), Rifampin, Pyrazinamide, Ethambutol, Streptomycin
    • Second-line drugs: Bedaquiline, Pretomanid, Capreomycin, Cycloserine, Levofloxacin, Ethionamide, Oflaxacin, Kanamycin, Para-aminosalicylic acid (PAS)### Tuberculosis (TB)
    • Contraindicated for patients with liver disease: Rifapentine
    • First bacteriostatic drug used to treat TB: Ethambutol
    • Causes optic neuritis in pediatric patients (younger than 13): Rifabutin

      • Adverse effects: headache, chest pain, nausea, and OT prolongation and cardiac arrest

    PPD (Purified Protein Derivatives, Mantoux)

    • An injection given intradermally to detect exposure to the TB organism
