Study Notes
Asthma and COPD Overview
- Asthma is characterized by eosinophilic inflammation of the airways which leads to obstructive episodes.
- Chronic Obstructive Pulmonary Disease (COPD) involves progressive, non-reversible airflow limitation, distinguishing it from asthma.
Common Causes and Characteristics
- Key risk factor for COPD includes being over 45 years old and having a history of smoking.
- Main symptom of asthma includes intermittent wheezing and shortness of breath, while a hallmark symptom in COPD is persistent cough with mucus production.
Treatments for Asthma
- First-line treatment for asthma exacerbations is short-acting beta-agonists (SABAs) like Salbutamol.
- Inhaled corticosteroids (ICS) are used as a 'preventer' in asthma management, requiring regular use for effectiveness.
- Common side effect of ICS includes oral candidiasis (thrush).
Long-acting Beta-agonists
- Formoterol is a long-acting beta-agonist (LABA) commonly used in combination with ICS for asthma management.
- LABAs should never be used alone in asthma treatment due to potential worsening of symptoms.
COPD Management Strategies
- Antimuscarinics (LAMA and SAMA) are the mainstay of bronchodilator therapy in COPD, providing effective bronchodilation by blocking muscarinic receptors.
- Combination therapy with LABA, LAMA, and ICS is recommended for patients with severe COPD to enhance survival and reduce exacerbations.
- Smoking cessation is critical in preventing COPD progression.
Monitoring and Potential Adverse Effects
- Patients on inhaled corticosteroids should be monitored for signs of oral thrush and hoarseness.
- Long-term high-dose ICS may lead to osteoporosis as a potential adverse effect.
Mechanisms of Action
- Leukotriene receptor antagonists (LTRAs) inhibit leukotriene-mediated bronchoconstriction and inflammation, aiding in asthma management.
- Long-acting muscarinic antagonists (LAMAs) help prevent bronchospasm by inhibiting acetylcholine in COPD management.
Goals of Management
- The primary goal of asthma management is to achieve normal lung function and prevent exacerbations, rather than eliminating all triggers or avoiding physical activity.
Asthma Characteristics and Drugs
- Asthma is a chronic inflammatory disorder of the airways.
- It involves reversible airflow obstruction and bronchial hyper-reactivity.
- Asthma is associated with eosinophilic inflammation, while neutrophilic inflammation does not characterize it.
Asthma and COPD Treatment
- Inhaled corticosteroids (ICS) are fundamental in asthma treatment, but are utilized in severe cases of Chronic Obstructive Pulmonary Disease (COPD).
- Distinctive for COPD is progressive and usually irreversible airflow limitation, contrasting with asthma's reversible nature.
Spirometry and Asthma
- An increase in Forced Expiratory Volume in one second (FEV1) after a bronchodilator is a significant indicator of asthma.
Side Effects of Medications
- Oral candidiasis is a common adverse effect noted with long-term use of inhaled corticosteroids.
Combination Therapy in Asthma
- Long-acting beta-agonists (LABA) should be combined with inhaled corticosteroids (ICS) for effective asthma management.
Quick Relief Medications
- Salbutamol, a short-acting beta-agonist (SABA), is the first-line bronchodilator for rapid relief in asthma and COPD exacerbations.
Drug Classes for COPD
- Long-acting muscarinic antagonists (LAMAs) are more beneficial in COPD management than in asthma, due to their effect on larger airways.
Leukotriene Receptor Antagonists (LTRAs)
- Montelukast is a notable LTRA employed in asthma treatment.
Management of Aspirin/NSAID-Induced Asthma
- For aspirin or NSAID-induced asthma exacerbations, the effective approach involves stopping the drug and administering an LTRA.
COPD Exacerbation Prevention
- Long-acting muscarinic antagonists (LAMAs) help prevent COPD exacerbations but offer limited benefits for non-allergic asthma patients.
Monitoring Drug Levels
- Theophylline demands careful monitoring because of its narrow therapeutic index.
Preference for Combination Therapy in COPD
- In COPD, LABA and LAMA combinations are favored over ICS due to an increased risk of pneumonia associated with ICS usage.
Common Inhaled Corticosteroid
- Fluticasone is frequently prescribed as an inhaled corticosteroid for asthma management.
Treatment Reassessment in Asthma
- Treatment can be stepped down when asthma has been controlled effectively for three months.
