Clinical Description

Overview of Nitroglycerin

Nitroglycerin is a medication commonly used to treat angina pectoris (chest pain) and heart failure. It works as a vasodilator, relaxing blood vessels to improve blood flow and reduce the heart's workload. However, it can also have toxic effects, particularly when used improperly or in excessive amounts.

Toxic Effects

The toxic effects of nitroglycerin and other nitric acids and esters can manifest in several ways, including:

• Cardiovascular Effects: Overdose can lead to hypotension (low blood pressure), tachycardia (rapid heart rate), and syncope (fainting). These effects occur due to the vasodilatory properties of nitroglycerin, which can cause excessive dilation of blood vessels.

• Neurological Symptoms: Patients may experience headaches, dizziness, or confusion. These symptoms are often due to the rapid drop in blood pressure and reduced cerebral perfusion.

• Gastrointestinal Distress: Nausea and vomiting can occur as a result of systemic toxicity.

• Respiratory Issues: In severe cases, respiratory depression may occur, particularly if the individual has underlying respiratory conditions.

Mechanism of Toxicity

The toxicity associated with nitroglycerin and similar compounds is primarily due to their action on the vascular system. When administered inappropriately, these substances can lead to an excessive release of nitric oxide, resulting in profound vasodilation and subsequent cardiovascular collapse.
