Exactly one hour after the addition of the calcium chloride solution, determine the extent of clotting in each tube, recognising three grades between zero and full clotting. The results demonstrated the validity of the anti-factor IIa assay that together with the anti-factor Xa are useful methodologies for the routine quality control of enoxaparin in pharmaceutical products. We've updated our privacy policy. HIT may progress to the development of venous and arterial thromboses, a condition referred to as Heparin-induced Thrombocytopenia and Thrombosis (HITT). You can read the details below. Heparin sodium does not cross the placenta, based on human and animal studies. 0000002510 00000 n
Although others may be present, the main sugars occurring in heparin are: (1) -L-iduronic acid 2-sulfate, (2) 2-deoxy-2- . Significant elevations of aminotransferase (SGOT [S-AST] and SGPT [S-ALT]) levels have occurred in a high percentage of patients (and healthy subjects) who have received heparin. For additional information consult the labeling of Protamine Sulfate Injection, USP products. To the Editor: Plasma is usually chosen for cell-free circulating DNA studies because ex vivo release of DNA from hematopoietic cells was demonstrated in serum during the clotting process from whole blood ()()().Among the most commonly used anticoagulants, EDTA, heparin, and citrate, heparin was suggested by some investigators to be an unsuitable anticoagulant because it could inhibit PCR ()()(). xb```sR cc`a84""CqB[`# :l&]>5@$4Kh@Z"X600pahga"f61 b7
b5.kbwGJAbfCq2s0'30; fc`p BIOASSAY OF HEPARIN SODIUM Heparin Sodium is a preparation containing the sodium salt of a complex organic acid present in mammalian tissues, and having the characteristic property of delaying the clotting of shed blood. The agency is continuing to aggressively investigate the situation. Frequently, a dose of 300 units of heparin sodium per kilogram of body weight is used for procedures estimated to last less than 60 minutes, or 400 units per kilogram for those estimated to last longer than 60 minutes.

No more than 50 mg should be administered, The method yielded good results with a detection limit of 0.01 IU/ml and a quantitation limit of 0.03 IU/ml. Local irritation, erythema, mild pain, hematoma or ulceration may follow deep subcutaneous (intrafat) injection of heparin sodium. Heparin Sodium intended for use in the manufacture of injectable preparations contains not less than 150 Units per mg and Heparin Sodium not intended for use in the manufacture of injectable preparations contains not less than 120 Units per mg, both calculated with reference to the dried substance. Dose: Prophylactic, by subcutaneous injection, 10,000 to 15,000 Units daily, in divided doses; therapeutic, by intravenous injection, 20,000 to 50,000 Units daily, in divided doses. WARNINGS, The potency is determined by a biological assay using a USP reference standard based endstream

It should be appreciated that gastrointestinal or urinary tract bleeding during anticoagulant therapy may indicate the presence of an underlying occult lesion. Carefully examine all Heparin Sodium Injection vials to confirm choice of the correct strength prior to administration of the drug. The low molecular weight heparin enoxaparin sodium is used clinically for the prevention and treatment of venous and arterial thrombosis. PRECAUTIONS, Leukocyte counts should be performed on heparinized blood within two hours after addition of the heparin.
