Metalyse and Actilyse

Metalyse and Actilyse are both thrombolytic drugs, those indicated to dissolve blood clots in cases of myocardial infarction.

Both drugs are applied intravenously (into the vein) and have a similar action in the treatment of heart attack.

However, the Actilyse package insert also indicates that the drug can be used to treat cases of acute ischemic stroke and acute pulmonary embolism – pulmonary artery blockage due to a clot.

The choice of which drug to use must be made by the responsible physician, who will evaluate the best option for each clinical picture.

Both are expensive drugs and must be administered by a trained health professional.


Heart attacks are more common than you think. Only in Brazil there are about 150 thousand cases per year.
