Suscard buccal tablets contain the active ingredient glyceryl trinitrate, which is a type of medicine called a nitrate. It is used to help the heart work more easily. (NB. Glyceryl trinitrate is also available without a brand name, ie as the generic medicine.)
Glyceryl trinitrate works by being converted in the body to a chemical called nitric oxide. This chemical is made naturally by the body and has the effect of making the veins and arteries relax and widen (dilate). When the blood vessels dilate in this way there is more space inside them and hence less resistance. This makes it easier for the heart to pump blood around the body.
Widening the veins also decreases the volume of blood that returns to the heart with each heartbeat. This makes it easier for the heart to pump that blood out again.
As a result of both these actions, the heart does not need as much energy to pump the blood around the body and therefore needs less oxygen.
Glyceryl trinitrate also widens the arteries within the heart itself, which increases the blood and oxygen supply to the heart muscle.
The pain of angina is caused by too little oxygen reaching the heart when its workload increases, such as during exercise. Glyceryl trinitrate improves the oxygen supply to the heart, as well as decreasing the amount of oxygen that the heart needs by making it easier for the heart to pump blood around the body. It can therefore be used to treat angina.
Glyceryl trinitrate can also be used in the treatment of heart failure, where the pumping action of the heart has become less effective.
Suscard buccal tablets should be placed high up between the upper lip and gum, to either side of the front teeth. They should be left there to dissolve. The medicine is absorbed into the bloodstream through the large supply of blood vessels in this area. The medicine starts to work rapidly and will keep working for as long as it takes the tablet to dissolve. This is normally between three and five hours.
Suscard tablets can be taken in this way when needed to provide rapid relief from the pain of an angina attack. They can also be used when needed to prevent an anticipated attack, for example before exercise or physical effort, emotional stress or exposure to cold.
Suscard tablets can also be used on a regular basis to help prevent angina attacks. If an acute attack of angina happens while a tablet is in place, an additional tablet may be positioned on the opposite side of the mouth.
