Slow release capsule

The use of nitroglycerin in sustained-release capsules is preferred for the prevention of angina in the long term. Here are the dosages:


The initial dose is 2.5–6.5 mg, taken 3-4 times a day. If necessary, the dose may be increased to 26 mg, 4 times daily.

Infusion fluid

During treatment with nitroglycerin, do not rush to stand up when getting up from sitting or when getting up from a lying position, as this can cause severe dizziness and fainting.
