What is a potential side effect of albuterol on the cardiovascular system?

Albuterol is a beta-2 adrenergic agonist primarily used to treat bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD). While its action mainly targets the bronchial smooth muscle to cause bronchodilation, it can also stimulate beta-1 adrenergic receptors in the heart at higher doses or in sensitive individuals.

The stimulation of these receptors can lead to heart palpitations, which are sensations of having a fast-beating, fluttering, or pounding heart. This side effect occurs because the increased heart rate and contractility can create a feeling of heightened awareness of heart activity.

While other potential cardiovascular effects can include issues like bradycardia or hypertension, these are not typical outcomes associated with albuterol usage. Bradycardia would involve a slowing of the heart rate, which is counter to the expected effects of a stimulatory agent like albuterol. Hypertension, while possible due to the increase in cardiac output, is not as commonly reported as heart palpitations. Similarly, constriction does not apply as albuterol is primarily associated with dilation of the bronchial passages rather than vascular constriction.

Therefore, heart palpitations are a well-documented potential side effect of albuterol related
