What is Activase used for?

Activase (Alteplase) is a thrombolytic medication used to treat acute ischemic stroke, deep vein thrombosis (DVT), and pulmonary embolism. It works by breaking down blood clots that have formed in the blood vessels, restoring blood flow to the affected areas [1].

How does Activase compare with tPA?

Activase is a recombinant tissue plasminogen activator (tPA), which is similar to tissue plasminogen activator (tPA). However, Activase has a slightly different mechanism of action and is more commonly used to treat DVT and pulmonary embolism [2].

When should Activase be administered?

Activase should be administered as soon as possible after the onset of symptoms to maximize its effectiveness. It is typically given intravenously over a period of several minutes, and patients must be closely monitored for potential bleeding complications [3].

What are the side effects of Activase?

Common side effects of Activase include bleeding, headache, nausea, and vomiting. Rare but serious side effects include hemorrhagic stroke, intracranial hemorrhage, and anaphylaxis. Patients should be closely monitored for these potential complications [4].

Can biosimilars enter before patent expiry?

The patent for Activase expired in 2019, allowing generic versions of the medication to enter the market. However, biosimilars, which are highly similar copies of biologic medications, have not yet been approved for Activase [5].
