Nitro-Dur is a vasodilator which is used in the prevention of angina (chest pain). This type of medication relieves an attack which is occurring if taken when the attack begins, prevents attacks from happening if taken before an attack is expected to occur and reduces the number of attacks if taken on a regular basis.
Nitro-Dur is a topical ointment which is applied to the skin. The nitroglycerin in the ointment is absorbed through the skin to relax the blood vessels and increase the supply of blood and oxygen to the heart. Only apply as much as your doctor prescribes. Taking too much or too little can compromise the healing process.
Common side effects associated with this type of medication include dizziness, lightheadedness, headache, flushed appearance, fast heartbeat, nausea and vomiting. If you begin experiencing more severe side effects, contact your doctor immediately.
Nitro-Dur may occasionally be prescribed for other purposes as well, as suggested by your doctor.
