Study Notes

Omalizumab (Xolair)

A monoclonal antibody that binds to IgE, preventing it from attaching to receptors on mast cells and basophils.
This action reduces allergic inflammation.
Indicated for moderate to severe allergic asthma unresponsive to inhaled corticosteroid (ICS) therapy.
Potential adverse effects include injection site reactions, headache, and possible anaphylaxis.
Contraindicated in individuals with hypersensitivity to any component of the formulation.
May interact with certain immunosuppressants or antipsychotics.
Monitoring for allergic reactions post-administration is crucial.

Albuterol (Ventolin)

A short-acting beta agonist (SABA).
Stimulates beta-2 receptors in bronchial smooth muscle, leading to bronchodilation.
Used for relief of acute bronchospasm and prevention of exercise-induced bronchospasm.
Potential adverse effects include tremor, tachycardia, and central nervous system stimulation.
Contraindicated in individuals with hypersensitivity to albuterol or other ingredients.
May have interactions with beta-blockers which diminish its effects.
Use caution with non-selective beta-blockers.

Salmeterol

A long-acting beta agonist (LABA).
Provides prolonged beta-2 receptor stimulation, resulting in extended bronchodilation.
Used as maintenance therapy for asthma when combined with ICS.
Potential adverse effects include headache, muscle cramps, and potential for tachycardia.
Not recommended for monotherapy in asthma.
Contraindicated in individuals with hypersensitivity to the medication.
Interactions with beta-blockers may counteract its effects.
Monitoring for potential cardiovascular side effects in at-risk patients is important.

Ipratropium (Atrovent)

A short-acting muscarinic antagonist (SAMA).
Blocks muscarinic receptors, reducing bronchoconstriction and mucus secretion.
Used for moderate to severe asthma exacerbations, often as adjunctive therapy.
Potential adverse effects include dry mouth, headache, and blurred vision.
Contraindicated in individuals with hypersensitivity to atropine derivatives.
Use caution in patients with glaucoma.
May interact with other anticholinergic agents.

Formoterol/Budesonide (Symbicort)

A combination ICS/LABA.
Budesonide reduces inflammation, while formoterol provides long-acting bronchodilation.
Used for maintenance therapy in asthma.
Some formulations can be used for acute symptom relief.
Potential adverse effects include oral thrush, headache, and tremor.
Not recommended for use in acute asthma exacerbations unless specifically indicated.
May interact with beta-blockers, reducing efficacy.
Use caution with certain antivirals, such as ritonavir.
Monitoring for signs of adrenal suppression with prolonged use is essential.

Beclomethasone (Qvar)

An inhaled corticosteroid (ICS).
Reduces airway inflammation by inhibiting inflammatory mediators.
Used for maintenance/controller therapy in asthma.
Potential adverse effects include oral thrush, headache, and pharyngitis.
Contraindicated in individuals with hypersensitivity to the medication.
Not recommended for acute asthma exacerbation.
Interactions with desmopressin (caution in pediatric nocturia).

Fluticasone (Arnuity Ellipta)

An inhaled corticosteroid (ICS).
Anti-inflammatory effects reduce airway swelling and mucus production.
Used for maintenance therapy in asthma.
Potential adverse effects include oral thrush, arthralgia, and headache.
Contraindicated in individuals with hypersensitivity to the medication.
Interactions with desmopressin (monitor in children).
Long-term use may warrant occasional monitoring for systemic effects.

Prednisone

An oral corticosteroid.
Broad anti-inflammatory action reduces immune response and inflammation.
Used for acute asthma exacerbations.
Potential adverse effects include hyperglycemia, insomnia, mood changes, and adrenal suppression with long-term use.
Contraindicated in individuals with hypersensitivity to the medication.
Use caution with live vaccines.
May interact with immunosuppressants, and increase blood glucose levels.
Monitoring of blood glucose and adrenal function with prolonged use is crucial.

Montelukast (Singulair)

A leukotriene receptor antagonist (LTRA).
Blocks leukotriene receptors, reducing inflammation and bronchoconstriction.
Used for asthma maintenance, particularly beneficial for children and patients with allergic asthma.
Potential adverse effects include rare but serious neuropsychiatric effects (e.g., mood changes).
Contraindicated in individuals with hypersensitivity to the medication.
Few drug interactions; use caution with certain psychiatric medications.
Monitoring for neuropsychiatric symptoms is important.

Asthma Severity Classification and Medication Therapy

Severity is classified based on symptom frequency, night awakenings, and rescue inhaler use.
Initial therapy is determined based on the frequency and severity of asthma symptoms.
Step 1: Low-dose ICS-formoterol PRN for infrequent symptoms.
Step 2: Low-dose ICS maintenance with PRN SABA or ICS-formoterol.
Step 3: Low-dose ICS-LABA for persistent symptoms most days.
Step 4: Medium/high-dose ICS-LABA for daily symptoms or low lung function.
Step 5: Medium/high-dose ICS-formoterol with add-ons (LAMA or biologics such as anti-IgE, anti-IL5).

Asthma Management: Stepwise Approach

Therapy should be adjusted based on control level, increasing stepwise for inadequate control or persistent symptoms and frequent exacerbations.
Control is determined by frequency and severity of symptoms.
Decrease therapy stepwise once asthma control is maintained for three months.
Each step incorporates a combination of ICS and LABA, with additional options such as LAMA or biologics for severe cases.

Goals of Asthma Therapy

The primary goals of asthma therapy are:
Controlling symptoms.
Maintaining lung function.
Preventing exacerbations.
Chronic therapy emphasizes daily controller medications to prevent airway remodeling and achieve long-term control.

Proper Inhaler Technique

MDI (Metered Dose Inhaler):
Shake the inhaler.
Exhale completely.
Press the inhaler while inhaling slowly and deeply.
Hold breath for 10 seconds.
Exhale slowly.
DPI (Dry Powder Inhaler):
Do not shake the inhaler.
Inhale quickly and deeply.
Hold breath for 10 seconds.
Exhale slowly.

Management of Acute Asthma Exacerbation

Administer SABA (e.g., albuterol) via MDI with a spacer or nebulizer every 20 minutes for the first hour.
Add systemic corticosteroids (e.g., prednisone) if moderate to severe symptoms persist.

Outpatient Asthma Management

Prescribe maintenance medications according to asthma control.
Educate patients on using a written asthma action plan and recognizing symptom worsening.
