Study Notes
Inhaled Anticholinergics
- Treats bronchospasm in asthma and COPD by blocking the parasympathetic nervous system.
- Promotes bronchodilation by enhancing sympathetic system activity.
- Potential side effects include nervousness, dizziness, headache, nausea, cough, palpitations, ocular changes, hypersensitivity, urinary retention, and paradoxical bronchospasm.
- Key drug: Ipratropium (Atrovent).
Xanthines
- Used for long-term control of chronic asthma or COPD.
- Increases cyclic adenosine monophosphate (cAMP) which regulates physiological processes leading to bronchodilation.
- Commonly associated with theophylline levels above 20 mcg/mL leading to risks such as irritability, restlessness, dizziness, palpitations, life-threatening arrhythmias, loss of appetite, proteinuria, respiratory arrest, fever, and flushing.
- Key drug: Theophylline (Theolair).
Glucocorticoids
- Provides long-term control of severe asthma or COPD by dampening inflammation and airway edema.
- Short-term therapy is effective for treating status asthmaticus by reducing mucus production and promoting responsiveness of beta-2 receptors.
- Long-term use can lead to side effects including pharyngitis, oral candidiasis, and bone mineralization issues, alongside immunosuppression risks.
- Key drugs: Beclomethasone (Qvar), Prednisone, Methylprednisolone (IV).
Leukotriene Modifiers
- Used for asthma or COPD prevention and exercise-induced bronchospasm.
- Suppresses the effects of leukotrienes, reducing airway edema, inflammation, bronchoconstriction, and mucus production.
- Key drug: Montelukast (Singulair).
Monoclonal Antibodies
- Effective in controlling persistent asthma or COPD symptoms by binding to IgE and blocking reactions to antigens.
- This mechanism inhibits the release of inflammatory mediators.
- Contraindications include infections and malignancies.
- Key drug: Omalizumab (Xolair).
Opioids
- Cough suppressants that act on the central nervous system by raising cough threshold to inhibit the cough reflex.
- Side effects may include sedation, respiratory depression, hypotension, GI upset, and constipation.
- Key drug: Codeine.
Non-opioids
- Suppress cough similarly by acting on the CNS without the opioid interaction.
- Side effects such as dizziness and sedation are more pronounced at high doses.
- Key drug: Dextromethorphan (Delsym).
Expectorants
- Promote mucus expectoration by thinning and increasing mucus flow.
- Allows for easier clearance of secretions from the respiratory tract.
- Common side effects include GI upset and dizziness.
- Key drug: Guaifenesin (Mucinex).
Classification and Uses
- Beta2-adrenergic agonists control asthma symptoms and are divided into Short-Acting (SABA) for rescue and Long-Acting (LABA) for maintenance.
- Xanthines are used for long-term control of chronic asthma or COPD.
- Glucocorticoids provide long-term control of severe asthma or COPD.
- Mucolytics promote expectoration by breaking down mucus structure, also beneficial in cystic fibrosis.
- Alpha-adrenergic agonists are indicated for allergic or non-allergic rhinitis and sinusitis.
- H1 Receptor Antagonists offer relief from common allergy symptoms.
- Nasal glucocorticoids are preferred for treating nasal congestion due to perennial allergies.
Mechanism of Action
- Beta2-adrenergic agonists bind to beta 2 receptors in bronchial smooth muscle to promote bronchodilation, relieve bronchospasm, and inhibit histamine release.
- Theophylline (a xanthine) increases cAMP levels, regulating physiological processes and aiding in bronchodilation.
- Glucocorticoids dampen inflammation by suppressing inflammatory cells and mediators.
- Mucolytics break down mucus to facilitate easier expectoration.
- Alpha-adrenergic agonists stimulate alpha1 adrenergic receptors, causing vasoconstriction and reducing nasal passage edema.
- H1 Receptor Antagonists block histamine's action at H1 receptors, reducing symptoms like itching and sneezing.
- Nasal glucocorticoids decrease secretion of inflammatory mediators, reducing mucosal edema.
Adverse Effects
- Beta2-adrenergic agonists may cause anxiety, dizziness, tachycardia, and paradoxical bronchospasm.
- Theophylline can lead to increased irritability, potential arrhythmias, or life-threatening respiratory arrest if levels exceed 20 mcg/mL.
- Glucocorticoids may result in throat soreness and candidiasis with prolonged use, along with bone mineralization issues.
- Mucolytics may induce bronchospasm, nausea, or vomiting.
- Alpha-adrenergic agonists can cause flushing, appetite loss, and feelings of restlessness.
- H1 Receptor Antagonists can lead to sedation or anticholinergic effects.
- Nasal glucocorticoids typically have a favorable safety profile but may still cause localized effects.

- Albuterol: Inhaled SABA for acute asthma relief.
- Salmeterol: Inhaled LABA for asthma maintenance.
- Terbutaline: Oral LABA for asthma.
- Theophylline: Long-term asthma management.
- Beclomethasone: Inhaled glucocorticoid for asthma control.
- Prednisone: Systemic glucocorticoid for severe conditions.
- Acetylcysteine: Mucolytic used for mucus breakup.
- Phenylephrine: Oral and nasal alpha-agonist for rhinitis.
- Diphenhydramine: H1 antagonist for allergy symptom relief.
- Mometasone: Nasal glucocorticoid for allergy-related congestion.
