Imagine how scary it would be if you suddenly had a heart attack or stroke. The biggest problem at such times is the dangerous blood clots that form inside the blood vessels of our body. If this blood clot gets stuck in a vein that carries blood to the heart or brain, it can cause serious damage. At such a critical moment in life, we are talking about a very powerful, special medicine that can dissolve those blood clots and save lives.
What is Alteplase?
Simply put, Alteplase is a drug that is injected into a vein and is used only in emergencies. Its main function is to dissolve blood clots that have formed in dangerous places in the body. That's why it is sometimes called a "clot buster".
When a heart attack occurs, the blood vessels supplying blood to the heart become blocked by a blood clot. Similarly, when a stroke occurs, a blood clot often blocks a blood vessel supplying blood to the brain. If this blood clot is quickly dissolved by administering the drug Alteplase, it can minimize damage to the heart or brain, increase the patient's ability to recover, and reduce the risk of disability.
The important thing is, this is not a medicine you can buy at a pharmacy and keep at home. It is only given in a hospital, under the direct supervision of doctors and nursing staff.
Things you need to tell your doctor before giving this medicine
Because Alteplase is a very powerful drug, it is essential that your doctor knows your complete medical history before prescribing it to you. This is because it can be dangerous to give this drug to someone with certain medical conditions. If you have any of the following conditions, you should definitely tell your doctor.
| Your health condition | Why is notification important? |
|---|---|
| Weakening of the wall of a blood vessel (Aneurysm) | There is a risk of the weakened vein bursting due to the action of the medicine. |
| Bleeding disorders or blood clotting problems | This medicine further increases the risk of bleeding. |
| Recent surgery or biopsy | Surgical wounds may bleed excessively. |
| Uncontrolled high blood pressure | Serious conditions such as brain bleeding can occur. |
| A head injury, brain tumor, or previous stroke | The risk of bleeding inside the skull is very high. |
| Eye damage caused by diabetes (Diabetic Retinopathy) | Bleeding in the eyes may occur. |
| Being pregnant, trying to get pregnant, or breastfeeding | The doctor must decide on the potential risks to the mother and baby. |
| Allergies to any other medicine or food | To prevent an allergic reaction to the medicine. |
How to use this medicine and what to be careful about
This medicine is given as an injection through a cannula inserted into a vein. This is done entirely in a hospital or clinic.
While taking the medicine
When you are given Alteplase, your condition will be closely monitored by doctors and nurses. Your heart rate, blood pressure, and other vital signs will be checked regularly. You will be advised to rest in bed to reduce the risk of bleeding.
Risk of bleeding
The main and most serious risk of this medication is bleeding. Alteplase works by dissolving blood clots and temporarily weakening the body's natural blood clotting process.
- Therefore , when brushing your teeth and cleaning your nose, you should do it very gently and carefully.
- Even a small wound on the body can cause more bleeding than normal.
- Never take other painkillers (especially NSAIDs) such as Aspirin and Ibuprofen , and other blood thinners such as Warfarin and Heparin without your doctor's permission.
What if the dose of the medicine increases?
Since this medicine is given in a hospital setting, you do not need to worry about the dosage. It is accurately calculated and administered by medical professionals. In case of any suspicion of an overdose, the hospital staff will immediately inform the hospital's Emergency Treatment Unit (ETU) or, if necessary , the National Poisons Information Centre at the Colombo National Hospital .
Possible side effects
Like any medicine, Alteplase can cause side effects. Some are serious and some are common.
| Side effect | Explanation |
|---|---|
| Side effects that should be reported to your doctor or nursing staff immediately | |
| Allergic Reactions | Skin rash, itching, swelling of the face, lips or tongue, difficulty breathing. |
| Bleeding symptoms | Black or tarry stools, red or dark brown urine, vomiting a substance that looks like coffee grounds, red spots on the skin, unusual bleeding from the gums, eyes, or nose. |
| Symptoms of a stroke | Vision changes, confusion, difficulty speaking or understanding, severe headache, sudden numbness or weakness in the face, arm or leg, difficulty walking, dizziness. |

👩🏽⚕️ Additional questions (FAQs)
💬 What is the Alteplase / tPA / Activase vaccine used for?
This is the most powerful 'clot buster / thrombolytic' drug in the world! Whether a patient has a sudden 'heart attack' or a brain clot that causes paralysis (ischemic stroke) within minutes (if brought to the hospital within 3 to 4.5 hours), it is a life-saving injection that is administered in the emergency department (IV) of a hospital to dissolve the blood clot and save the patient's life 100%!
💬 How can this injection (Alteplase) instantly dissolve a blood clot stuck in the brain/heart?
What this does is forcefully turn on our own body's own dissolving machine (Plasmin)! A blood clot is formed when blood cells are entangled in a mesh called 'Fibrin'. Once this injection enters the body, it finds that blood clot (Tissue Plasminogen Activator) and activates the enzyme called plasmin inside it to the maximum. Then, the mesh (Fibrin) is cut into pieces, dissolved, and blood circulation begins again.
💬 Even if a patient is saved by this vaccine (tPA), what is the most serious fatal risk (Black Box Warning)?
The biggest danger is 'Intracranial Hemorrhage'! This dissolves blood clots, so if there is a small wound anywhere in the body, it will continue to bleed and the bleeding will not be able to stop. Sometimes a blood vessel in the brain bursts and the paralysis improves, but even if the patient bleeds into the brain, it is fatal and can cause immediate death! (That is why bleeding disorders/pressure are definitely checked before giving this).
