Background and Date of Approval
Alteplase, under the brand name Activase, received FDA approval on November 10, 1987, for treating acute myocardial infarction (heart attack).
Mechanism of Action of undefined
Alteplase converts plasminogen enzyme to plasmin, which helps in breaking down of fibrin present in blood clots, which leads to restoration of blood flow. So it is used in acute ischemic stroke; it dissolves clots, minimizing damage.
Uses of undefined
Alteplase is used to dissolve blood clots and restore blood flow in conditions such as acute ischemic stroke, acute myocardial infarction (heart attack), and pulmonary embolism.
undefined Drug administaration and Dosage available
Alteplase is administered intravenously (injection in a vein) under medical supervision. Your healthcare professional will determine the specific dosage and administration guidelines based on your condition and needs.
Warnings, Precautions and Side Effects of undefined
Alteplase carries several warnings that should be considered before use. Serious allergic reactions, including anaphylaxis, can necessitate immediate medical attention if symptoms like difficulty breathing or facial swelling occur. This medication significantly increases the risk of bleeding. Serious bleeding events can occur at various sites in the body, including the brain, gastrointestinal tract, and other critical locations. It can lead to bleeding in the brain, resulting in a condition called intracranial hemorrhage. This is a severe and potentially life-threatening complication.
In some cases, blood vessels may re-occlude (re-form blood clots) after initial treatment. This may necessitate additional interventions to address the recurrent clotting. It can cause a drop in blood pressure (hypotension), leading to symptoms such as dizziness, lightheadedness, or fainting.
It is essential to avoid using alteplase in patients with active bleeding or a history of recent significant bleeding events. Due to the risk, this medication is contraindicated in patients with a history of intracranial hemorrhage or known structural cerebral vascular lesions. Close monitoring of blood pressure is crucial during treatment.
Alteplase may cause several side effects, the most significant being an increased risk of bleeding, which can lead to serious and life-threatening complications. Other common side effects include fever, headache, nausea, vomiting, and bleeding at the injection site. Serious allergic reactions and hypersensitivity may occur in some individuals.
