Question: 1 / 400

What is a common side effect of chronic use of bronchodilators?

Hypotension

Tachycardia

Chronic use of bronchodilators often leads to tachycardia, which is an increased heart rate. This side effect occurs primarily due to the stimulation of the adrenergic nervous system; many bronchodilators, especially those that are β-agonists (like albuterol), activate β-adrenergic receptors that not only relax bronchial smooth muscles but can also influence the heart, resulting in a higher heart rate.

In patients using bronchodilators regularly, particularly at higher doses, monitoring for cardiac effects is essential. Although other factors can contribute to heart rate changes, the mechanism of action of these medications predisposes patients to experience tachycardia as a common side effect. Understanding this relationship can help healthcare providers manage symptoms effectively and provide appropriate patient education.
