What does a gtn spray do to the body?

Glyceryl trinitrate (GTN) spray is primarily used to relieve angina pectoris, a type of chest pain caused by reduced blood flow to the heart. When administered, GTN dilates blood vessels, improving blood flow and oxygen delivery to the heart muscle. This vasodilation also helps to lower blood pressure and reduces the heart's workload. As a result, GTN spray alleviates the symptoms of angina and can provide quick relief during episodes of chest pain.
