What happens if nitroglycerin is infused too quickly?

Nitroglycerin administered too quickly may cause symptoms such as dizziness, worsened hypoxia, and decreased blood pressure in patients.

1. Dizziness

Nitroglycerin is a medication used for intravenous infusion. If the infusion rate is too fast, it can easily lead to cerebral vasodilation, resulting in dizziness. In particular, patients with cerebral hemorrhage should use this drug cautiously.

2. Worsened Hypoxia

Nitroglycerin has a vasodilatory effect. When infused too rapidly, it may cause an imbalance between blood flow and ventilation, thereby exacerbating hypoxia in the patient.

3. Decreased Blood Pressure

If nitroglycerin is infused too quickly, it may also trigger certain adverse complications, such as bradycardia or tachycardia, and even lead to a significant drop in blood pressure.

In addition to the above symptoms, excessively rapid administration of nitroglycerin may also induce nitroglycerin tolerance. It is recommended to strictly follow medical instructions when using this medication. Patients with inferior wall myocardial infarction or right ventricular infarction should use this drug with caution.
