Nitroglycerin belongs to a class of drugs known as nitrates.How to use nitroglycerin rect

Cover your finger with plastic wrap, a disposable medical glove, or a finger cot. Using the measuring guide that comes with your product, squeeze out the prescribed amount of ointment onto your finger. Gently insert your finger inside the anus, up to the first finger joint. Spread the ointment around the inside of the anus. If you cannot do this because it is too painful, you may apply the ointment to the outside of the anus.
