1. What Urokinase Teofarma 250,000 U.I. is and what it is used for
Urokinase Teofarma belongs to a group of medicines called antithrombotics.
Urokinase is an enzyme extracted from human urine and is used to lyse thrombi (break down blood clots) and prevent obstruction of blood vessels.
Urokinase Teofarma is indicated in:
- Thromboembolic treatment of: peripheral arterial thromboembolism and deep vein thrombosis.
- Massive or hemodynamically unstable acute pulmonary embolism.
- Thrombosis of arteriovenous shunts.
- Intraocular hemorrhages.
- Coronary thrombosis: Urokinase has been used for the destruction of the acute thrombus that obstructs the coronary arteries associated with transmural myocardial infarction. Most patients who receive urokinase by intracoronary infusion within 6 hours after the onset of symptoms show recanalization of the affected vessel.
It has not been demonstrated that intracoronary administration of urokinase during transmural myocardial infarction achieves recovery of the affected myocardial tissue, nor that it reduces mortality. The characteristics of patients who could benefit from this therapy have not been defined.
- Metapneumonic pleural effusions and complicated empyemas.
2. Before using Urokinase Teofarma 250,000 U.I.
Treatment with urokinase should always be carried out in a specialized institution and under strict medical supervision.
Do not use Urokinase Teofarma if you are in any of the following situations:
- Major bleeding at present or during the last 6 months.
- Treatment with oral anticoagulants and an INR > 1.3 (laboratory parameter).
- History of central nervous system injury (e.g., neoplasia or tumor process, aneurysm or vascular dilation, intracranial or spinal surgery).
- Known predisposition to bleeding.
- Uncontrolled severe hypertension.
- Major surgical procedures, biopsy, or sampling of organs or significant trauma during the last 2 months (including any trauma associated with the current acute myocardial infarction).
- Recent head or skull trauma.
- Prolonged cardiopulmonary resuscitation (> 2 minutes) during the last 2 weeks.
- Pericarditis or acute pericardial inflammation and/or endocarditis or infectious cardiac endocarditis of bacterial origin.
- Pancreatitis or acute pancreatic inflammation.
- Severe liver disorders, including insufficiency or liver failure, cirrhosis, portal hypertension (esophageal varices), and active hepatitis.
- Active peptic ulcer.
- Aneurysm or arterial dilation and known arteriovenous malformation.
- Tumor process with increased risk of bleeding.
- Known history of stroke or cerebral vascular accident, transient ischemic attack, or dementia.
- If you are allergic (hypersensitive) to the active substance or to any of the other components of Urokinase Teofarma.
Be careful with Urokinase Teofarma
If you are in the following situations:
- Systolic blood pressure above 160 mmHg.
- Cerebrovascular disease.
- Recent bleeding (within the last 10 days) of gastrointestinal or genitourinary origin.
- High probability of thrombi in the left heart cavities, e.g., in occlusion or stenosis of the mitral valve of the heart with altered heart rhythm or atrial fibrillation.
- Any recent intramuscular injection (within the last 2 days)
- Advanced age, e.g., over 75 years.
- If you are being treated with Urokinase Teofarma for pulmonary embolism, your doctor should perform a series of tests at least every four hours.
Intramuscular and intraarterial injections should be avoided during treatment.
Use of other medicines
If administered together with antiplatelet agents (acetylsalicylic acid, indomethacin, phenylbutazone, etc.), oral anticoagulants, or heparin, blood coagulation parameters should be frequently monitored, as the risk of bleeding increases.
Tell your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription.
Pregnancy and breastfeeding
The safety of use during pregnancy and breastfeeding has not been established, so it should be used with caution.
If you are pregnant or think you may be pregnant, inform your doctor before starting treatment.
If you are breastfeeding or plan to breastfeed, inform your doctor.
It is not known whether Urokinase Teofarma is excreted in breast milk. Breast milk should be discarded during the first 24 hours after treatment.
Driving and using machines
Urokinase Teofarma does not interfere with the ability to drive and use machines.
Important information about some of the components of Urokinase Teofarma
This medicine contains less than 23 mg (1 mmol) of sodium per dose, so it is considered essentially "sodium-free".
3. How to use Urokinase Teofarma 250,000 U.I.
Follow exactly the administration instructions of Urokinase Teofarma indicated by your doctor. Consult your doctor or pharmacist if you have doubts.
The usual method of administration is by continuous intravenous infusion, dissolved in isotonic saline solution.
Urokinase should not be administered in the same mixture with other medicines.
Massive or hemodynamically unstable acute pulmonary embolism
The recommended regimen for pulmonary embolism is: 4,400 U.I./kg in 10 minutes, as an initial dose, followed by continuous infusion of 4,400 U.I./kg/hour for 12 hours.
Anticoagulant therapy
In the treatment of pulmonary embolism, it is usually indicated to follow therapy with continuous infusion of heparin to prevent recurrence of the thrombus. Treatment with heparin, if initiated, should not begin until the thrombin time value is less than twice the normal control value (approximately 3-4 hours after discontinuing urokinase infusion).
Arteriovenous shunt occlusions
Use 5,000 - 10,000 U.I. dissolved in 0.5-1 ml of isotonic saline solution.
Intraocular hemorrhages
From 5,000 to 25,000 U.I., in direct intraocular instillation.
Metapneumonic pleural effusions and complicated empyemas
The usual dose is 100,000 U.I. three times a day for a period of 2 to 6 days approximately.
Once the catheter is placed, all possible pleural fluid is aspirated. Then, 100,000 U.I. of Urokinase Teofarma dissolved in 10 ml of physiological serum are instilled, closing the catheter valve for 2 hours. Then, a new aspiration of pleural fluid and a new instillation of urokinase are performed, repeating this operation a total of three times a day, until the complete resolution of the pleural effusion and/or when the flow of the same is scarce in the last 24 hours (< 20 ml) and/or when the biological marker of fibrinolytic activity (D-dimer) demonstrates the ineffectiveness of the treatment.
Use in children
The safety and efficacy of the use of Urokinase Teofarma in children have not been established.
Elderly patients
In patients over 75 years of age, the benefit should be evaluated against the potential risk of an acute cerebrovascular accident. It is recommended to carefully select patients and monitor them.
If you use more Urokinase Teofarma than you should:
It may cause bleeding that can disappear when treatment is interrupted. If necessary, in cases where bleeding persists, it is advisable to administer substances that neutralize the effect of urokinase, such as aprotinin, aminocaproic acid, or tranexamic acid. In other cases, administration of human blood plasma, complete plasma, or whole blood may be required.
A characteristic of urokinase to be taken into account is that it remains in the body for a short time and is rapidly eliminated.
In case of overdose or accidental ingestion, consult the Toxicology Information Service. Telephone 915 620 420.
4. Possible side effects
Like all medicines, Urokinase Teofarma can cause side effects, although not everybody gets them.
Bleeding may occur at the injection site and, in isolated cases, generalized bleeding.
Treatment with urokinase may rarely cause mild allergic reactions, bronchospasm (contraction of bronchial muscle that causes difficulty breathing), skin reaction, and fever.
If an allergic reaction occurs, the infusion should be discontinued.
As with other thrombolytic agents (antithrombotics), some possible cardiovascular effects have been described, such as hypotension (decrease in blood pressure), alterations in heart rhythm and frequency, recurrent cardiac ischemia, or pulmonary embolism.
If you consider that any of the side effects you are suffering from is serious or if you notice any side effect not mentioned in this leaflet, inform your doctor or pharmacist.
