Study Notes
Bronchodilators
- Bronchodilators are medications used to open up the airways in the lungs
-
Beta2-agonists stimulate beta2 receptors in the lungs, causing smooth muscle relaxation. This leads to bronchodilation and improved airflow.
- Short-acting beta2-agonists like albuterol and levalbuterol provide rapid relief during acute asthma exacerbations.
- Long-acting beta2-agonists like salmeterol and formoterol provide longer-lasting bronchodilation, used for preventing asthma attacks.
-
Anticholinergics block the action of acetylcholine, a neurotransmitter that constricts airway smooth muscles.
- Ipratropium and tiotropium are anticholinergic medications used to treat chronic obstructive pulmonary disease (COPD) and asthma.
-
Methylxanthines are a group of drugs that include theophylline and aminophylline.
- Theophylline relaxes airway smooth muscle and also has anti-inflammatory effects.
Anti-inflammatory Agents
-
Steroids are powerful anti-inflammatory medications that reduce inflammation in the airways of people with asthma.
- Inhaled steroids like beclomethasone and fluticasone are the most common way to deliver steroids for asthma treatment.
- Oral steroids like methylprednisolone and prednisone are used for short-term treatment of severe asthma exacerbations.
-
Leukotriene inhibitors block the action of leukotrienes, inflammatory chemicals in the body that contribute to asthma symptoms.
- Montelukast and zafirlukast are examples of leukotriene inhibitors.
- Mast cell stabilizers, like cromolyn, work by preventing the release of histamine and other inflammatory mediators from mast cells.
-
Phosphodiesterase-4 inhibitors block the enzyme phosphodiesterase-4, leading to increased cyclic adenosine monophosphate (cAMP) levels in the airways.
- Roflumilast is an example of a PDE-4 inhibitor used to treat COPD.
Bronchodilators
- Bronchodilators are used to open the airways in the lungs, making it easier to breathe.
- There are three main types: beta2-agonists, anticholinergics, and methylxanthines.
Beta2-Agonists
- Beta2-agonists work by relaxing the muscles that surround the airways.
- Short-acting beta2-agonists, such as albuterol and levalbuterol, are used to quickly relieve symptoms of wheezing and shortness of breath.
- Long-acting beta2-agonists, such as salmeterol and formoterol, are used to prevent symptoms from occurring, and are taken twice a day.
Anticholinergics
- Anticholinergics work by blocking the action of acetylcholine, a neurotransmitter that causes the airways to constrict.
- Examples include ipratropium and tiotropium.
Methylxanthines
- Methylxanthines work by relaxing the airway muscles and decreasing inflammation in the lungs.
- Important examples include theophylline and aminophylline.
Anti-inflammatory Agents
- Anti-inflammatory agents are used to reduce inflammation in the airways.
- They are often used alongside bronchodilators to manage asthma and other respiratory diseases.
Steroids
- Steroids are powerful anti-inflammatory agents that are widely used in the treatment of asthma.
- Inhaled corticosteroids, such as beclomethasone and fluticasone, are the mainstay of asthma treatment, and are inhaled directly into the lungs.
- Oral steroids such as methylprednisolone and prednisone are taken by mouth and are used for more severe asthma attacks or when inhaled steroids are ineffective.
Leukotriene Inhibitors
- Leukotrienes are inflammatory chemicals produced by the body that contribute to asthma symptoms.
- Leukotriene inhibitors block the production of leukotrienes, reducing inflammation and improving lung function.
- Examples include montelukast and zafirlukast.
Mast Cell Stabilizers
- Mast cells are immune cells that release histamine, a chemical that triggers allergic reactions and causes inflammation in the airways.
- Mast cell stabilizers, like cromolyn, prevent mast cells from releasing histamine.
Phosphodiesterase-4 inhibitors
- Phosphodiesterase-4 inhibitors block the action of an enzyme called phosphodiesterase-4, which plays a role in inflammation.
- An example is roflumilast.
Bronchodilators
- Bronchodilators are medications that help open up the airways in the lungs, making it easier to breathe.
- There are three main types: Beta2-agonists, anticholinergics, and methylxanthines.
-
Beta2-agonists stimulate the beta2-receptors in the lungs, causing relaxation of the smooth muscles and airway dilation.
- Short-acting beta-agonists like albuterol and levalbuterol provide quick relief of bronchospasm.
- Long-acting beta-agonists like salmeterol and formoterol provide longer-lasting bronchodilation, for prevention of symptoms.
-
Anticholinergics block the effects of acetylcholine, a neurotransmitter that constricts airways by stimulating muscles.
- Ipratropium and tiotropium are examples of anticholinergics used to treat asthma and COPD.
- Methylxanthines like theophylline and aminophylline have a complex mechanism of action, but they are known to relax airway smooth muscles and reduce inflammation.
Anti-inflammatory Agents
- Anti-inflammatory agents help reduce inflammation in the airways, reducing the severity of asthma symptoms.
- There are several classes of anti-inflammatory agents.
-
Steroids are powerful anti-inflammatory drugs.
- Inhaled steroids like beclomethasone and fluticasone deliver the drug directly to the airways, reducing side effects.
- Oral steroids like methylprednisolone and prednisone are more potent and used for short-term relief of severe asthma attacks.
-
Leukotriene inhibitors block the action of leukotrienes, inflammatory mediators that contribute to asthma symptoms.
- Montelukast and zafirlukast are common examples.
- Mast cell stabilizers like cromolyn prevent the release of histamine and other inflammatory chemicals from mast cells, reducing airway inflammation.
- Phosphodiesterase-4 inhibitors like roflumilast inhibit the breakdown of cyclic AMP, a molecule that promotes smooth muscle relaxation and reduces inflammation.
Bronchodilators
- Bronchodilators help open up the airways in the lungs, making it easier to breathe
- Short-acting beta2-agonists like albuterol and levalbuterol are used for quick relief of wheezing and shortness of breath
- Long-acting beta2-agonists like salmeterol and formoterol are used to prevent asthma symptoms
- Anticholinergics like ipratropium and tiotropium help relax the muscles in the airways
- Methylxanthines like theophylline and aminophylline are less commonly used bronchodilators
Anti-inflammatory Agents
- Anti-inflammatory agents help reduce inflammation in the airways
- Steroids, both inhaled (beclomethasone, fluticasone) and oral (methylprednisolone, prednisone), are powerful anti-inflammatories
- Leukotriene inhibitors like montelukast and zafirlukast block the action of chemicals that cause inflammation
