Generic Name: Alteplase
Product Name: Actilyse
Alteplase belongs to a group of medicines known as fibrinolytics. Alteplase breaks down unwanted blood clots, for example, in the lungs (called a pulmonary embolism). It is also given intravenously as soon as possible after the onset of a heart attack to dissolve clots in the arteries of the heart wall. This reduces the amount of damage to the heart muscle. Actilyse can be given to dissolve clots in the vessels in the brain, for example, those which cause strokes.
Alteplase belongs to a group of medicines known as fibrinolytics. It works by attaching to a blood clot and stimulating extra production of a substance produced naturally by the body called plasmin. Plasmin is produced in the blood to break down the major constituent of blood clots (fibrin), thereby dissolving clots once they have fullfilled their purpose in stopping bleeding. Extra production of plasmin caused by alteplase breaks down unwanted blood clots, for example, in the lungs (pulmonary embolism).
