Nitroderm TTS general information

What is Nitroderm TTS used for?

Nitroderm TTS 10 (transdermal therapeutic system) is a transdermal patch that is used to treat angina pectoris to prevent or reduce the frequency of angina attacks, to relieve symptoms including chest pain or discomfort and breathlessness on exertion.  Angina is usually an indication of coronary heart disease (CHD) cause by clogged arteries in the heart (atherosclerosis), and angina attack can occur in response to activities or situation known to trigger angina, like physical effort, emotional stress or exposure to cold.  Nitroderm TTS 10 can be used as monotherapy or in conjunction with other anti-angina medications such as beta blockers or calcium antagonists.  Nitroderm TTS 10 is also used to treat congestive heart failure (CHF) in patients who are not responding adequately to conventional treatment with other medication for CHF.  Symptoms of CHF include swelling due to water retention in the tissues, particularly the feet and ankles, also the lungs, caused by weakened heart muscles so that the heart cannot pump blood efficiently, resulting in blood collecting in the smallest blood vessels, the capillaries, which become leaky.  Nitroderm TTS 10 is not intended for rapid and immediate relief of an acute angina attacks.  For acute angina attack you should use a rapid acting medication such as a sublingual nitrate (under the tongue) preparations. 

How does Nitroderm TTS work?

Nitroderm TTS 10 is a transdermal adhesive patch that contains nitroglycerine (glyceryl trinitrate) 50mg, a potent vasodilator used to relax and widen peripheral arteries and veins, to treat acute angina and congestive heart failure.  Angina is caused by insufficient blood to the heart due to a reduction of blood flow.  This is usually caused by narrowing of the arteries of the heart (coronary arteries) because of a blockage due to deposition of cholesterol in the vessel walls (atherosclerosis).  Nitroglycerine in Nitroderm TTS 10 is converted to nitric oxide in the blood vessel walls and this acts directly on the vascular smooth muscle in the blood vessel walls, causing them to dilate and widen (vasodilation).  This action reduces pooling of blood and resistance to blood flow in the peripheral veins which means that the heart does not need to work so hard to pump blood.  This reduces the workload on the heart and also the need for oxygen at rest and during exertion, thereby enhancing the capacity for exercise.  Nitroglycerine in Nitroderm TTS 10 also causes widening of the coronary arteries, which helps get more oxygen to the heart muscle and relieves symptoms of acute angina attack including pain in the chest, referred pain to the arms or neck and breathlessness on exertion.  The vasodilatory action of nitroglycerine in Nitroderm TTS 10 on peripheral veins reduces the left ventricular filling pressure of the heart, which improves the pumping efficiency of the heart and reduces congestion of the pulmonary vein that causes symptoms of congestive heart failure.  Nitroderm TTS 10 is a multilayer system that delivers nitroglycerine continuously through a release membrane, through the skin and directly into the blood. 

What does Nitroderm TTS contain?

Nitroderm TTS 10 contains the active ingredient nitroglycerine (50mg), used to treat angina pectoris and congestive heart failure.  The Nitroderm TTS 10 transdermal system delivers 10mg nitroglycerine directly into the blood circulation every 24 hours.  Nitroderm TTS 10 also contains silica aerogel, silicone oil 360 medical adhesive.

Treating angina with Nitroderm TTS

Nitroderm TTS 10 is a transdermal adhesive patch that contains nitroglycerine (glyceryl trinitrate) 50mg, a vasodilator that is used to treat angina and prevent angina attacks.  Angina is usually an indication of coronary heart disease (CHD) and is caused by insufficient blood to the heart due to a reduction of blood flow.  This is usually due to narrowing of the arteries of the heart (coronary arteries) because of a blockage caused by deposition of cholesterol in the vessel walls (atherosclerosis).  Spasm of the coronary arteries can also cause reduced blood flow to the heart and induce an angina attack.  Nitroglycerine in Nitroderm TTS 10 is converted to nitric oxide in the blood vessel walls and this acts directly on the vascular smooth muscle in the blood vessel walls, causing them to dilate and widen (vasodilation).  This action reduces pooling of blood and resistance to blood flow in the peripheral veins which means that the heart does not need to work so hard to pump blood.  This reduces the workload on the heart and also the need for oxygen at rest and during exertion, thereby enhancing the capacity for exercise.  Nitroglycerine in Nitroderm TTS 10 also causes widening of the coronary arteries, which helps get more oxygen to the heart muscle and relieves symptoms of acute angina attack including pain in the chest, referred pain to the arms or neck and breathlessness on exertion.  Nitroderm TTS 10 is a multilayer system that delivers nitroglycerine continuously through a release membrane, through the skin and directly into the blood.  Nitroderm TTS 10 is not intended for rapid and immediate relief of an acute angina attacks.  For acute angina attack you should use a rapid acting medication such as a sublingual nitrate (under the tongue) preparations.
