Clinical dalteparin can be used to treat thrombophlebitis, myocardial infarction, pulmonary embolism, lower limb deep venous embolism and other cardiovascular diseases. What does dalteparin do? Can heparin sodium cause adverse reactions to patients? Dalteparin can prevent thrombosis or embolic disease, but there are some adverse conditions and patients who need to take it should be cautious.

　　Dalteparin API is the main component of heparin sodium injection, which is a sodium salt of aminoglycan sulfate extracted and refined from pig intestine mucosa or postage, belonging to mucoglycan.

　　After dalteparin enters the human body, its strong charge and rich physical and chemical properties can interfere with many links in the coagulation process, and have anticoagulation effect on both inside and outside the human body. Therefore, for some cardiovascular diseases, such as thrombophlebitis, myocardial infarction, pulmonary embolism, lower limb deep vein thrombosis and other diseases, it has the function of preventing thrombosis and embolic diseases.

　　During the use of Dalteparin, there will be some adverse reactions, especially bleeding. Therefore, clotting time should be monitored before each injection. If severe bleeding occurs after injection, protamine sulfate should be injected for first aid.

　　In addition, other patients will appear chills, fever, urticaria and other allergic reactions, a small number of patients will appear asthma, rhinitis, tearing, headache, nausea and vomiting. If subcutaneous deep injection is used, local stimulation appears erythema, edema, ulcer and so on. May also occur, as well as rare thrombocytopenia. These adverse reactions, though rare, are serious and caution must be exercised.

　　Dalteparin plays a very important role in the prevention of thrombosis in the treatment of cardiovascular diseases, but this drug should not be used arbitrarily, especially for patients with allergies, bleeding, slow coagulation and traumatic ulcers, so it should be used with caution or forbidden. It is imperative to follow the guidance of professional doctors to ensure drug safety.
