Alteplase
(Redirected from Actilyse)
What is Alteplase?[edit | edit source]
- Alteplase (Activase) is a tissue plasminogen activator (tPA) used used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure.
- Alteplase is used under brand name Cathflo Activase for the treatment of blocked central venous catheter.
What are the uses of this medicine?[edit | edit source]
Alteplase (Activase) is used for the treatment of
- Acute Ischemic Stroke (AIS).
- Acute Myocardial Infarction (AMI) to reduce mortality and incidence of heart failure.
- Acute Massive Pulmonary Embolism (PE) for lysis.
Limitation of Use in AMI:
- The risk of stroke may be greater than the benefit in patients at low risk of death from cardiac causes.
How does this medicine work?[edit | edit source]
- Alteplase is a recombinant therapeutic agent which is chemically identical to or similar to endogenous tissue plasminogen activator (tPA).
- tPA is a serine protease which converts plasminogen to plasmin, a fibrinolytic enzyme.
- Upon administration, alteplase increases plasmin enzymatic activity, resulting in hyperfibrinolysis and potential dissolution of a thrombus or embolism.
Who Should Not Use this medicine ?[edit | edit source]
Do not administer Activase to treat acute ischemic stroke in the following situations in which the risk of bleeding is greater than the potential benefit:
- Current intracranial hemorrhage
- Subarachnoid hemorrhage
- Active internal bleeding
- Recent (within 3 months) intracranial or intraspinal surgery or serious head trauma
- Presence of intracranial conditions that may increase the risk of bleeding (e.g., some neoplasms, arteriovenous malformations, or aneurysms)
- Bleeding diathesis
- Current severe uncontrolled hypertension
Do not administer Activase for treatment of Acute Myocardial Infarction or Pulmonary Embolism in the following situations in which the risk of bleeding is greater than the potential benefit
- Active internal bleeding
- History of recent stroke
- Recent (within 3 months) intracranial or intraspinal surgery or serious head trauma
- Presence of intracranial conditions that may increase the risk of bleeding (e.g. some neoplasms, arteriovenous malformations, or aneurysms)
- Bleeding diathesis
- Current severe uncontrolled hypertension
What drug interactions can this medicine cause?[edit | edit source]
- Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
Be sure to mention if you are taking any of the following:
Is this medicine FDA approved?[edit | edit source]
- Alteplase was approved for medical use in the United States in November 1987 for the treatment of myocardial infarction.
How should this medicine be used?[edit | edit source]
Recommended dosage: Acute Ischemic Stroke:
- The recommended dose is 0.9 mg/kg (not to exceed 90 mg total dose) infused intravenously over 60 minutes with 10% of the total dose administered as an initial bolus over 1 minute.
- Administer Activase as soon as possible but within 3 hours after onset of symptoms.
- During and following Activase administration for the treatment of acute ischemic stroke, frequently monitor and control blood pressure.
Acute Myocardial Infarction:
- Administer Activase as soon as possible after the onset of symptoms.
- The recommended total dose is based on patient weight, not to exceed 100 mg.
Acute Massive Pulmonary Embolism:
- The recommended dose is 100 mg administered by IV infusion over 2 hours.
Administration:
- Activase is for [[intravenous] administration only.
- Do not add any other medication to infusion solutions containing Activase.

What side effects can this medication cause?[edit | edit source]
The most common side effects of this medicine include:
- bleeding
- Hypersensitivity
- Thromboembolism
- Cholesterol Embolization
What special precautions should I follow?[edit | edit source]
- Activase can cause significant, sometimes fatal, internal or external bleeding, especially at arterial and venous puncture sites. Avoid intramuscular injections and trauma to the patient while on Activase. Perform venipunctures carefully and only as required. Monitor for bleeding. If serious bleeding occurs, discontinue Activase.
- Hypersensitivity, including urticarial / anaphylactic reactions, have been reported after administration of Activase (e.g., laryngeal edema, rash and shock). Monitor patients during and for several hours after infusion for hypersensitivity. If signs of hypersensitivity develop, discontinue Activase.
- The use of thrombolytics can increase the risk of thrombo-embolic events in patients with high likelihood of left heart thrombus, such as patients with mitral stenosis or atrial fibrillation. Consider the risk of reembolization from the lysis of underlying deep venous thrombi in patients with pulmonary embolism.
- Cholesterol embolism has been reported rarely in patients treated with thrombolytic agents; the true incidence is unknown. It is associated with invasive vascular procedures (e.g., cardiac catheterization, angiography, vascular surgery) and/or anticoagulant therapy.
- Coagulation tests and measures of fibrinolytic activity may be unreliable during Activase therapy. Activase remains active under in vitro conditions, which can result in degradation of fibrinogen in blood samples removed for analysis.
What to do in case of emergency/overdose?[edit | edit source]
In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.
- Overdose related information is also available online at poisonhelp.org/help.
