- QUESTION: Can you tell me about the new ways to take nitroglycerin?
-

-
- ANSWER: Nitroglycerin is the drug most often given for angina, which is chest
- pain and pressure caused by coronary artery disease. In coronary artery
- disease, arteries that supply the heart with blood are blocked by plaques
- (also known as "atheroma") which are composed of fatty materials like
- cholesterol. The blocked heart arteries can't carry as much blood as the
- heart muscle needs, and the result is angina. Nitroglycerin temporarily
- widens those blocked arteries, allowing more blood to flow to the heart
- muscle.
- You are probably most familiar with the tiny "nitro" pill that is placed
- under the tongue and allowed to dissolve there. This immediate-acting
- nitroglycerin is also available in a spray that can be sprayed under the
- tongue, or it can be injected straight into a vein. Any of these forms of
- nitroglycerin are short-acting, effective for only about 15-20 minutes.
- Intermediate-acting nitroglycerin lasts for a few hours and is used to
- prevent angina instead of to treat it. This pill or capsule is either
- swallowed or placed in the mouth between the cheek and jaw. It begins to work
- within about half an hour.
- Longer-acting nitroglycerin is prepared as an ointment that is absorbed
- through the skin. It is supplied in a tube like toothpaste and is squirted
- onto a piece of paper that is printed with a ruler. The exact prescribed
- amount of ointment is applied to the ruler paper, then the paper is used to
- spread the ointment on an area of skin that is about six inches long by at
- least three inches wide. Most people apply it to the chest, but it can be
- applied to any nonhairy part of the upper body. Do not apply the ointment to
- your legs or feet, because many people with heart disease have decreased
- circulation there. If the circulation is poor, the nitroglycerin won't be
- absorbed properly.
- Another way to use nitroglycerin is in the form of a patch that is
- already prepared, requiring no ointment or preparation by the user. Many
- people prefer these "transdermal patches" because they are convenient. These
- patches are available in several doses, and should be used as packaged, and
- not cut in half.
