【Contraindication】 1. Forbidden for patients with history of thrombus
2. It is forbidden for those who are allergic to this product or similar drugs.
【Attentions】 1. Bleeding caused by damaged arteries and large veins must be treated with timely surgery.
2. Disseminated intravascular coagulation (DIC) and bleeding caused by blood diseases are not the indication of Hemocoagulase For Injection.
3. After dissolution, if turbidity or precipitation occurs, do not used.
4. When there is a lack of platelets or some coagulation factors in the blood (such as prothrombin, etc.), there is no compensatory effect of Hemocoagulase For Injection, which should be applied on the basis of supplementation of platelets or lack of coagulation factors, or infusion of fresh blood.
5. In the case of primary fibrinolytic system hyperfunction (such as endocrine glands, cancer surgery, etc.), Hemocoagulase For Injection should be used in combination with anti-fibrinolytic drugs.
6. Patients' bleeding and coagulation time should be observed during use.
7. Intravenous infusion is recommended.
【Drugs for pregnant women and lactating women]】Pregnant women should not use them unless there is an emergency.

【Drug interaction】Currently, there are no reports of interactions with other drugs, but it is not suitable to mix with other drugs for intravenous injection in order to prevent the drug effect from decreasing.
【Drug overdose】According to the literature, at large doses (50-100ku/time), it has a strong effect of defibrinogen, which can significantly reduce the fibrinogen in the blood, and reduce the blood viscosity and coagulation.
【Pharmacology and toxicology】This drug is a Hemocoagulase which extracted from Agkistrodon blomhoffii ussurensis, It contains batroxobin and thromboplastin, two kinds of enzymes for a similar enzyme action, in the presence of Ca2+, can activate factor Ⅴ, Ⅶ and Ⅷ, and stimulate platelet agglutination; in the presence of platelet factor Ⅲ, thromboplastin can induce prothrombin into thrombin, can also activate factor Ⅴ, and influence factor X. The results of animal experiments showed that the drugs had a pro-coagulant effect in small dose and had an anticoagulant effect in large dose.
【Pharmacokinetics】The drug can be absorbed by intravenous, muscular, subcutaneous and intraperitoneal administration.Hemostatic effect can be produced 5~30 minutes after administration, lasting for 48~72 hours. The drug can be combined with plasma protein and gradually become an inactive compound. Its metabolites are excreted slowly by the kidney and can only be completely eliminated in 3 to 4 days.
【Storage】 Sealed and stored in a cool, dark place (not more than 20℃ away from light).
