Thrombolytic Medicines for Pulmonary Embolism
Thrombolytic medicines, such as streptokinase, urokinase, or tissue-type plasminogen activator (t-PA), interfere with the action of thrombin, which is needed to form blood clots. These medicines help to dissolve blood clots and may be used to treat pulmonary embolism in life-threatening situations.

Bleeding inside the brain is a particular danger that can cause a stroke or death. In general, thrombolytics are used only where the risk of bleeding can be balanced against the risks of not dissolving the blood clot rapidly. Thrombolytics might be used when you have a large blood clot that is:
