Study Notes

Chronic Obstructive Pulmonary Disease (COPD)

  • COPD is caused by chronic exposure to irritants like smoking, damaging lung tissue.
  • Two key components are chronic bronchitis (inflammation and mucus buildup in bronchi) and emphysema (damage to alveoli, reducing gas exchange surface area).
  • Airflow limitation is a result, progressive, and irreversible.

COPD Drugs

  • Bronchodilators (Beta-2 agonists, anticholinergics): Relax bronchial smooth muscle, relieving bronchospasm in COPD. Side effects include tachycardia, tremors, dry mouth, and blurred vision. Contraindicated in glaucoma, urinary retention, or heart disease.
  • Corticosteroids (Fluticasone, Budesonide): Reduce airway inflammation, manage chronic COPD, especially exacerbations. Side effects include oral thrush, hoarseness, and osteoporosis. Use cautiously in systemic infections, diabetes, or fungal infections
  • Phosphodiesterase-4 Inhibitors (Roflumilast): Reduce inflammation by increasing cAMP, used in severe COPD. Side effects include diarrhea, weight loss, and nausea. Avoid in liver disease.

Asthma

  • Asthma is a reversible airway obstruction with inflammation in small airways.
  • Key causes include edema, excess mucus production, and bronchoconstriction.
  • Asthma triggers include allergens, infections, exercise, and irritants.

Asthma Drugs

  • Short-Acting Beta Agonists (SABA): (e.g., Albuterol) provide rapid relief during acute attacks through beta-2 receptor stimulation for bronchodilation. Side effects include tachycardia, palpitations, and nervousness. Contraindicated in heart disease or hyperthyroidism.
  • Inhaled Corticosteroids (ICS): (e.g., Fluticasone, Budesonide) reduce airway inflammation by suppressing immune responses. Used for long-term control and prevention of asthma symptoms. Higher dose options have potential systemic side effects.
  • Leukotriene Receptor Antagonists (LTRA): (e.g., Montelukast) prevent bronchoconstriction and inflammation by blocking leukotriene receptors; used for allergic asthma. Side effects include headache and gastrointestinal issues.
  • Long-Acting Beta Agonists (LABA): (e.g., Salmeterol) provide sustained bronchodilation. Combination with ICS is common. Should not be used alone as their use alone may increase risk of asthma exacerbations. Side effects include tachycardia and tremors.

Pneumonia

  • Pneumonia is a lung infection causing inflammation and fluid buildup in alveoli, impairing gas exchange.
  • Common causes include bacteria (Streptococcus pneumoniae), viruses, or fungi.
  • Symptoms include cough, fever, chills, difficulty breathing, and chest pain.

Pneumonia Drugs

  • Antibiotics: (Penicillin, Macrolides) target bacterial cell wall or protein synthesis, treating bacterial pneumonia. Side effects include diarrhea and allergic reactions.
  • Antivirals: (Oseltamivir) prevent viral replication, treating influenza-related pneumonia. Side effects may include nausea, headache, and fatigue.
  • Oxygen Therapy: Essential to maintain adequate blood oxygen levels, especially in cases of severe pneumonia. Oxygen toxicity risk exists with prolonged use at high concentrations. Note cautions from renal impairment.

Interesting Facts

  • COPD is a major global cause of death, primarily due to smoking.
  • Asthma affects 8-10% of the population, often triggered by environmental factors like dust mites and pollen.
  • Pneumonia contributes significantly to global mortality, particularly in the elderly.
