If you have coronary artery disease and have episodes of chest pain (angina), a healthcare provider may prescribe Nitro-Bid. This medicine is specifically designed to prevent angina attacks from occurring. It is not helpful for treating an attack that has already started. Some possible "off-label," or unapproved, Nitro-Bid uses may include treating anal fissures and Raynaud's phenomenon.
What Is Nitro-Bid Used For?Nitro-Bid® (nitroglycerin ointment) is a prescription skin ointment specifically approved for preventing angina pectoris associated with coronary artery disease. This means that this drug is approved to help prevent episodes of chest pain caused by coronary artery disease (also known as coronary heart disease), a condition in which the small blood vessels that supply oxygen to the heart become too narrow to adequately supply the heart with enough blood and oxygen.
Nitro-Bid does not work quickly enough to stop an angina attack that is already occurring. Therefore, this medicine is not appropriate for people who have only occasional or rare episodes of angina. It is also inappropriate for people who have angina due to other causes.
How Does Nitro-Bid Work?Nitro-Bid works by relaxing the veins and arteries in the body. With the arteries and veins relaxed, the heart does not need to work so hard and does not require as much oxygen. Because angina is usually caused when there is not enough oxygen to meet the heart's needs, using Nitro-Bid can help prevent angina attacks.
Because the body rapidly becomes accustomed to the effects of nitroglycerin when it is used around the clock, it is essential that a 10- to 12-hour break from Nitro-Bid occurs every day (see Nitro-Bid Dosage). Without this break, the drug will become ineffective within 24 hours.
