Which adverse effect may occur with the use of nitrates?

Nitrates, commonly used as antianginal agents, work by dilating blood vessels to relieve chest pain associated with angina. One of the main adverse effects of nitrates is hypotension. This occurs because the vasodilation can lead to a decrease in blood pressure, particularly when a person stands up or after physical activity. Patients might experience symptoms like dizziness or lightheadedness due to the drop in blood pressure. It's important for healthcare providers to monitor blood pressure in patients using nitrates, especially when initiating therapy or increasing the dose.

Other potential adverse effects like hyperkalemia, constipation, and nausea are not typically associated with nitrates. Hyperkalemia is more related to medications affecting renal function or potassium levels. Constipation can be linked to other medications or lifestyle factors, whereas nausea is a more general side effect that can occur with various medications but is not specific to nitrates. Understanding the specific adverse effects associated with different drugs helps manage patient care effectively.
