Urokinase
CAS No. : 9039-53-6 (Plasminogen activator;fibrinolytic; enzyme)

Short Description:

Source: Extracted from fresh male urine
Function and use: Urokinase is a fibrinolytic drug, which can hydrolyze protein, has no antigenicity, and can directly activate plasminogen. This product is mainly used for the treatment of acute myocardial infarction, acute cerebral thrombosis, cerebral vascular occlusion, peripheral arteriovenous thrombosis, central retinal vein thrombosis and other infarct diseases caused by the formation of new blood clots.

Specification

Urokinase
Source			Fresh human urine
Process description			This product is an enzyme obtained from fresh human urine that activates plasminogen. It consists of a mixture of low-molecular-mass (LMM) (33 000) and high-molecular-mass (HMM) (54 000) forms.
Manufacturing requirements			This product should be extracted from healthy human urine. The production process should conform with the requirements of current version of Good Manufacturing Practice. This product should have virus safety control measures in the production process, and the process needs to be heated at 60℃ for 10 hours to inactivate the virus.

Category			Thrombolytic drugs

Indications

The product is mainly used for thrombolytic therapy of thromboembolic diseases. These include acute generalized pulmonary embolism, coronary artery embolism and myocardial infarction within 6-12 hours of chest pain, acute cerebrovascular embolism with symptoms shorter than 3-6 hours, retinal artery embolism and other peripheral artery embolism symptoms of severe skeletal vein thrombosis. It is also used to prevent thrombosis after prosthetic heart valve surgery, and to keep vascular cannulation and thoracic and pericardial drainage tubes unobstructed. Thrombolytic efficacy requires subsequent heparin anticoagulation to maintain.

The product is an enzyme thrombolytic drug, which can activate the conversion of plasminogen into plasmin in the body, thereby hydrolyzing fibrin to dissolve the freshly formed thrombus. For acute myocardial infarction, acute cerebral thrombosis and cerebral vascular embolism, perilimb arteriovenous thrombosis, central retinal arteriovenous thrombosis and other fresh thrombo occlusive diseases. The product has no obvious effect on old thrombosis. It is also suitable for the treatment of cerebral thrombosis, peripheral vascular embolism, central retinal vascular embolism, acute myocardial infarction and other fresh thromboembolic diseases, as well as kidney transplantation, plastic surgery and other thrombosis, all have good efficacy.
