Low dose aspirin helps reduce blood stickiness, the tendency of blood to clot. Cartia is used to help protect against some of the problems which can be caused by clotting in the blood stream. Cartia may be useful if you are at risk of coronary artery disease, angina, transient ischaemic attacks (TIAs or mini strokes), stroke (due to a blood clot) or heart attack. Cartia contains 100mg of aspirin and has a special Duentric coating. Experts recommend low dose aspirin as it keeps the blood from clotting and doing so reduces the risk of heart attack or stroke. The aspirin in Cartia is released in the upper intestine where it is absorbed gradually into the bloodstream. This slow absorption is believed to be necessary to maximise the anti-clotting effect.
