Which medication should be monitored for tachycardia as a side effect?

Monitoring for tachycardia is particularly important with albuterol, a medication that is a bronchodilator commonly used in the treatment of asthma and other conditions causing bronchospasm. Albuterol works by stimulating beta-2 adrenergic receptors in the lungs, leading to relaxation of bronchial smooth muscle and dilation of airways, which facilitates easier breathing.

However, stimulation of beta-adrenergic receptors can also lead to increased heart rate, as these receptors are present in the heart as well. Therefore, tachycardia can occur as a side effect when using albuterol, particularly in patients who might be sensitive to its cardiovascular effects or in those who may be using it in high doses or frequently. It's essential for healthcare providers to monitor their patients for signs of increased heart rate and other cardiovascular responses when prescribing this medication to ensure patient safety and appropriate management of any potential side effects.

In the context of the other medications listed, amantadine is primarily an antiviral and a dopaminergic agent used in Parkinson's disease and certain viral infections but is less commonly associated with tachycardia as a side effect. Haloperidol, an antipsychotic medication, may have side effects on the cardiovascular system, but tachycardia is
