Velix Introduction
Velix is a recombinant tissue-type plasminogen activator (tPA) that is used in acute myocardial infarction to restore blood flow in the heart muscle. It is a derivative of native tPA, and is a protein manufactured by recombinant DNA technology and administered intravenously.
Uses for Velix
Velix is primarily used to treat acute coronary syndrome, which is a heart complication that occurs when a blood clot blocks a coronary artery. It is also used to treat patients with non-ST-elevation myocardial infarctions (NSTEMIs) and other thrombolytic indications.
Velix Mechanism of Action
Velix works by activating plasminogen, a protein found in plasma. This activates the formation of plasmin, an enzyme that breaks down fibrin, a protein responsible for forming blood clots. By breaking down clots, Velix reopens blocked arteries and restoring regular blood flow to the heart.
How Long Does It Take to Work?
Velix works very quickly. It takes about 90 minutes to reach peak concentration in the bloodstream and can cause a decrease in clot size in as little as five minutes.
Velix Absorption
Velix is rapidly and virtually completely absorbed after administration. It is hydrolyzed to inactive metabolites, with only trace amounts of intact tenecteplase being present in the bloodstream.

Velix is eliminated primarily through renal clearance, with approximately 40% of the drug being excreted unchanged in the urine.
