Study Notes
Inhaled Corticosteroids
- Inhaled corticosteroids are used for long-term asthma management and to prevent exacerbations.
- Examples of inhaled corticosteroids include: Beclomethasone dipropionate, Budesonide, Ciclesonide, Flunisolide, Fluticasone, Mometasone, and Triamcinolone acetonide.
- Ciclesonide has a longer duration of action than other inhaled corticosteroids.
- Fluticasone is available in inhaled and intranasal forms, used for asthma and allergic rhinitis respectively.
- Contraindications for inhaled corticosteroids include: drug allergy and acute asthma attacks.
Respiratory Drugs
- Respiratory drugs are essential for the treatment and management of lung and airway conditions.
- These medications alleviate symptoms, improve lung function, and prevent exacerbations.
Diseases of the Lower Respiratory Tract
- COPD stands for Chronic Obstructive Pulmonary Disease and encompasses a group of chronic lung diseases like chronic bronchitis and emphysema, causing airflow obstruction.
- Asthma is a chronic inflammatory disease characterized by recurring episodes of wheezing, breathlessness, chest tightness, and coughing.
- Emphysema damages the alveoli, causing them to lose elasticity and impair expansion and contraction.
- Chronic bronchitis is a condition where airway inflammation and swelling cause persistent cough and excess mucus production.
Bronchial Asthma
- Bronchial asthma is a chronic inflammatory disorder causing recurrent episodes of wheezing, breathlessness, chest tightness, and coughing.
- Asthma is characterized by airway inflammation leading to bronchospasm and mucus hypersecretion.
- Inflammation involves the recruitment of inflammatory cells like eosinophils, mast cells, and lymphocytes into the airway walls.
Asthma Categories
- Intrinsic asthma occurs in individuals without allergies or specific triggers.
- Extrinsic asthma develops in individuals exposed to known allergens like pollen, dust mites, or animal dander.
- Exercise-induced asthma is triggered by physical exertion, often in individuals with a history of asthma.
- Drug-induced asthma is caused by exposure to certain medications such as aspirin or beta-blockers.
- Anticholinergic medications block the action of acetylcholine, a neurotransmitter in the parasympathetic nervous system.
- Corticosteroids reduce inflammation in the airways.
Leukotriene Receptor Antagonists (LTRAs)
- Leukotrienes are inflammatory substances released when triggers like cat hair or dust initiate chemical reactions in the body.
- Leukotrienes cause inflammation, bronchoconstriction, and mucus production leading to coughing, wheezing, and shortness of breath.
- LTRAs block leukotrienes from attaching to their receptors.
- LTRAs reduce inflammation in the lungs and decrease airway constriction.
- LTRAs are used for prophylaxis and long-term management of asthma in adults and children 12 years and older.
- LTRAs are not for treating acute asthma exacerbations.
- LTRAs are not for immediate relief of acute asthma attacks.
LTRAs: Drug Effects
- LTRAs reduce mucus secretion, which can contribute to airway obstruction.
- LTRAs decrease inflammation in the lungs by reducing neutrophil and leukocyte infiltration.
- Montelukast, an LTRA, carries a black box warning for serious mood changes and behaviors.
Bronchodilators: Short-acting Beta-Agonists (SABAs)
- SABAs are used for rapid relief of acute asthma or COPD episodes.
- SABAs stimulate beta-2 adrenergic receptors in the bronchioles, leading to muscle relaxation and bronchodilation.
- SABAs increase airflow and improve lung function.
- SABAs are typically used for short-term relief of symptoms.
Bronchodilators: Long-acting Beta-Agonists (LABAs)
- LABAs relax airway muscle, making it easier to breathe.
- LABAs provide long-lasting relief, lasting 12 hours or more.
- LABAs are never used for acute asthma attacks, only for long-term asthma symptom management.
Bronchodilators: Beta-Adrenergic Agonists: Newest LABA
- Indacaterol is a long-acting beta-agonist (LABA) indicated for the long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD.
- Vilanterol is available in combination with Fluticasone (Breo Ellipta) or the anticholinergic, Umeclidinium (Anoro Ellipta).
- Ellipta refers to a unique dry powder inhaler delivery system designed to improve patient adherence and compliance.
Bronchodilators: Acute Phase
- Beta-adrenergic agonists are used to quickly relieve airway constriction during acute asthma attacks.
- These drugs help restore normal airflow by relaxing the bronchiole smooth muscle.
- Beta-adrenergic agonists are generally for short-term relief of acute asthma symptoms.
Xanthine Derivatives: Adverse Effects
- Gastrointestinal side effects include nausea, vomiting, loss of appetite, and gastroesophageal reflux.
- Cardiovascular effects include increased heart rate and arrhythmias.
- Urinary side effects include transient increased urination.
- Metabolic side effects include hyperglycemia, especially in patients with diabetes.
Xanthine Derivatives: Caffeine
- Caffeine is used over-the-counter as a central nervous system stimulant to promote alertness.
- Caffeine is used as a cardiac stimulant in infants with bradycardia.
- Caffeine can enhance respiratory drive in infants.
Xanthine Derivatives: Theophylline
- Theophylline is available in oral, rectal, injectable, and topical forms.
- Aminophylline is an intravenous (IV) form used for patients with status asthmaticus who have not responded to fast-acting beta agonists.
- The therapeutic range for theophylline blood levels is 10 to 20 mcg/mL.
Nonbronchodilating Respiratory Drugs
- Leukotriene receptor antagonists (LTRAs) prevent asthma attacks but don't treat acute attacks.
- Corticosteroids reduce inflammation in the airways and help prevent asthma attacks.
- Mast cell stabilizers prevent the release of histamine, reducing inflammation and airway constriction.
Leukotriene Receptor Antagonists (LTRAs)
- LTRAs are a newer class of asthma medications that don't directly relax airway smooth muscle.
- LTRAs offer an alternative to traditional asthma medications like beta-agonists and corticosteroids.
