Common side effects of which medication include tachycardia?

Theophylline is a medication often used for the treatment of asthma and chronic obstructive pulmonary disease (COPD). It acts as a bronchodilator, relaxing the muscles of the airways to improve breathing. One of the common side effects associated with theophylline is tachycardia, or an increased heart rate. This occurs due to its action as a methylxanthine, which can stimulate the central nervous system and heart.

Theophylline can also lead to other cardiovascular effects; it increases cardiac output and can stimulate the heart, potentially resulting in an elevated heart rate. Such side effects are often dose-dependent; higher levels of theophylline in the blood can exacerbate these symptoms, leading to tachycardia.

While gabapentin, alprazolam, and ezetimibe have their own sets of side effects, tachycardia is not commonly associated with them. Gabapentin is typically used for neuropathic pain and seizure disorders and is more likely to cause sedation or dizziness. Alprazolam, a benzodiazepine, primarily causes sedation or drowsiness and can lead to dependency with chronic use. Ezetimibe, which is used to lower cholesterol, does not typically result in tach
