🟦 Bronchodilator Definition
Bronchodilators are one of the most common classes of medications that are used in the field of respiratory care. They’re often used for the treatment of obstructive conditions such as asthma and COPD.

➡️ There are two primary types of bronchodilators:
1. Adrenergic
2. Anticholinergic  

➡️ Adrenergic Bronchodilators
Adrenergic bronchodilators act on beta-2 receptors in the airways which causes the smooth muscle tissue to relax and helps the airways open back up. This is why they are effective in treating conditions that cause acute bronchospasm.

➡️ Types of Adrenergic Bronchodilators:
- Short-Acting Beta-2 Agonists
- Long-Acting Beta-2 Agonists

Short-Acting Beta-2 Agonists are known as rescue drugs because they are used to treat acute bronchospasm. For example, if a patient is having an acute asthma attack, then a short-acting bronchodilator would be indicated. Long-Acting Beta-2 Agonists, on the other hand, are known as maintenance medications. That is because they are used to control and maintain conditions that cause chronic bronchospasm. For example, they would be useful for the maintenance of patients with stable asthma and COPD who are not having an acute exacerbation. If a patient is having an acute attack, a short, fast-acting bronchodilator would be indicated. However, if they're in stable condition, this is where long-acting bronchodilators are useful to help prevent acute exacerbations from occurring.

➡️ Short-Acting Beta-2 Agonists:
- Albuterol (Ventolin, Proventil)
- Levalbuterol (Xopenex)
- Metaproterenol (Alupent)

➡️ Long-Acting Beta-2 Agonists:
- Arformoterol (Brovana)
- Salmeterol (Serevent)
- Formoterol (Foradil, Perforomist)

➡️ Anticholinergic Bronchodilators
Anticholinergic bronchodilators act on the parasympathetic nervous system. They work by blocking the mechanism of action of the neurotransmitter acetylcholine (ACh) which promotes relaxation of the smooth muscles in the airways of the lungs. There are both short-acting and long-acting anticholinergic agents as well. Ipratropium Bromide (Atrovent) is the most common short-acting anticholinergic bronchodilator.

➡️ Some examples of long-acting anticholinergic agents include:
- Aclidinium Bromide (Tudorza)
- Tiotropium Bromide (Spiriva)
- Umeclidinium (Anoro)
