Drug Class

• Nitrate vasodilator

What Experts Say

Glyceryl trinitrate belongs to a group of medicines called nitrate vasodilators. It relaxes the smooth muscle inside blood vessel walls, which widens veins and arteries throughout the body. This lowers the amount of blood returning to the heart and reduces the pressure the heart must pump against.

Because this injection acts within minutes, hospitals use it as a continuous intravenous infusion for angina that has not responded to other treatment, acute heart failure with fluid buildup in the lungs, and dangerously high blood pressure that needs fast control. Trained staff adjust the infusion rate slowly while watching blood pressure and heart rhythm closely.

Extended use over several days can lead to reduced effectiveness, known as nitrate tolerance, so doctors often plan short nitrate free periods. Sudden drops in blood pressure, headache and flushing are the most common effects reported during infusion. This medicine should never be combined with erectile dysfunction drugs, since the combination can cause a severe and dangerous fall in blood pressure.

Drug Interactions

Risks and warnings

• Low blood pressure: Can cause a sudden and significant drop in blood pressure, especially when starting the infusion.
• Recent heart attack: Requires close monitoring since blood pressure can fall sharply in this setting.
• Head injury or bleeding in the brain: Avoid use, as it can raise pressure inside the skull.
• Severe anemia: Use with caution as it may worsen oxygen delivery to tissues.
