Bradycardia is a potential side effect of which medication?

Bradycardia, which is a slower than normal heart rate, is commonly associated with the use of digoxin. This medication is a cardiac glycoside primarily used to treat heart conditions such as atrial fibrillation and heart failure. Digoxin exerts its effects by increasing the force of cardiac contractions and also slowing the conduction through the atrioventricular (AV) node. This slowing effect can often lead to bradycardia, especially if the dosage is too high or if the patient has underlying conditions that make them more sensitive to the effects of the drug.

Other medication classes listed, such as antibiotics, ACE inhibitors, and statins, do not have a direct association with causing bradycardia as a common side effect. While they may have various cardiovascular effects, they generally do not slow the heart rate to the degree that digoxin does. Therefore, digoxin is the most relevant choice when considering medications that can lead to bradycardia.
