Description
11 DESCRIPTION Heparin is a heterogenous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans having anticoagulant properties. It is composed of polymers of alternating derivations of alpha-L-iduronic acid 2-sulfate (1), 2-deoxy-2-sulfamino- alpha-D-glucose 6-sulfate (2), beta-D-glucuronic acid (3), 2-acetamido-2- deoxy-alpha-D-glucose (4), and alpha-L-iduronic acid (5). Structure of Heparin Sodium (representative subunits): Heparin Sodium in 5% Dextrose Injection is a sterile, nonpyrogenic solution prepared from Heparin Sodium USP (derived from porcine intestinal mucosa and standardized for use as an anticoagulant) and Hydrous Dextrose USP. It is to be administered by intravenous injection. The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram. The pH range is 5.6 (4.5 – 7.0) and the osmolarity mOsmol/L (calc.) is 315. The concentration of electrolytes is 38 mEq/L Sodium, 30 mEq/L Phosphate, and 15 mEq/L Citrate. 40 USP units/mL: Each 100 mL of the 20,000 USP units per 500 mL preparation contains: 4,000 USP units of heparin sodium, 5 g Hydrous Dextrose USP, 0.41 g Dibasic Sodium Phosphate, 0.093 g Citric Acid Anhydrous USP, 0.0686 g Sodium Metabisulfite NF (antioxidant), and Water for Injection USP until quantity sufficient. 50 USP units/mL: Each 100 mL of the 25,000 USP units per 500 mL preparation contains: 5,000 USP units of heparin sodium, 5 g Hydrous Dextrose USP, 0.41 g Dibasic Sodium Phosphate, 0.093 g Citric Acid Anhydrous USP, 0.0686 g Sodium Metabisulfite NF (antioxidant), and Water for Injection USP until quantity sufficient. 100 USP units/mL: Each 100 mL of the 25,000 USP units per 250 mL preparation contains: 10,000 USP units of heparin sodium, 5 g Hydrous Dextrose USP, 0.41 g Dibasic Sodium Phosphate, 0.093 g Citric Acid Anhydrous USP, 0.0686 g Sodium Metabisulfite NF (antioxidant), and Water for Injection USP until quantity sufficient.

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hemorrhage [see Warnings and Precautions (5.2) ] Heparin-Induced Thrombocytopenia and Heparin-Induced Thrombocytopenia with Thrombosis [see Warnings and Precautions (5.3) ] Thrombocytopenia [see Warnings and Precautions (5.4) ] Heparin Resistance [see Warnings and Precautions (5.6) ] Hypersensitivity [see Warnings and Precautions (5.7) ] Hyperkalemia [see Warnings and Precautions (5.8) ] Elevations of Serum Aminotransferases [see Warnings and Precautions (5.9) ] Most common adverse reactions are: hemorrhage, thrombocytopenia, HIT or HITT, heparin resistance, hypersensitivity reactions, hyperkalemia, and elevations of aminotransferase levels. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact B. Braun Medical Inc. at 1-800-227-2862 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Postmarketing Experience The following adverse reactions have been identified during post-approval use of heparin sodium. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency. Hemorrhage – Hemorrhage is the chief complication that may result from heparin therapy [see Warnings and Precautions (5.2) ] . An overly prolonged clotting time or minor bleeding during therapy can usually be controlled by withdrawing the drug [see Overdosage (10) ] . Gastrointestinal or urinary tract bleeding during anticoagulant therapy may indicate the presence of an underlying occult lesion. Bleeding can occur at any site but certain specific hemorrhagic complications may be difficult to detect: Adrenal hemorrhage, with resultant acute adrenal insufficiency, has occurred with heparin therapy, including fatal cases. Ovarian (corpus luteum) hemorrhage developed in a number of women of reproductive age receiving short- or long-term anticoagulant therapy. Retroperitoneal hemorrhage. Vascular Disorders – Contusion, Vasospastic reactions (including episodes of painful, ischemic, and cyanosed limbs). HIT and HITT, including delayed onset cases, and Thrombocytopenia – [see Warnings and Precautions ( 5.3 and 5.4 )] Histamine-like reactions – Such reactions have been observed at the site of injections. Necrosis of the skin has been reported at the site of subcutaneous injection of heparin, occasionally requiring skin grafting. Hypersensitivity – Generalized hypersensitivity reactions have been reported with chills, fever, and urticaria as the most usual manifestations, and asthma, rhinitis, lacrimation, headache, nausea and vomiting, and anaphylactoid reactions, including shock, occurring more rarely. Itching and burning, especially on the plantar site of the feet, may occur [see Warnings and Precautions ( 5.7 )] . Musculoskeletal, Connective Tissue and Bone Disorders – Osteoporosis with long-term administration of heparin. Metabolism and Nutrition Disorders – Hyperkalemia. General Disorders and Administration Site Conditions – Erythema, mild pain, ulceration. Elevations of serum aminotransferases – Significant elevations of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels have occurred in patients who have received heparin. Others – Osteoporosis following long-term administration of high-doses of heparin, cutaneous necrosis after systemic administration, suppression of aldosterone synthesis, delayed transient alopecia, priapism, and rebound hyperlipemia on discontinuation of heparin sodium have also been reported.
Drug Interactions
7 DRUG INTERACTIONS Drugs that interfere with coagulation, platelet aggregation or drugs that counteract coagulation may induce bleeding. ( 7 ) 7.1 Oral Anticoagulants Heparin sodium may prolong the one-stage prothrombin time. Therefore, when heparin sodium is given with dicumarol or warfarin sodium, a period of at least 5 hours after the last intravenous dose or 24 hours after the last subcutaneous dose should elapse before blood is drawn if a valid prothrombin time is to be obtained. 7.2 Platelet Inhibitors Drugs such as NSAIDS (including acetylsalicylic acid, ibuprofen, indomethacin, and celecoxib), dextran, phenylbutazone, thienopyridines, dipyridamole, hydroxychloroquine, glycoprotein IIv/IIa antagonists (including abciximab, eptifibatide, and tirofiban), and others that interfere with platelet-aggregation reactions (the main hemostatic defense of heparinized patients) may induce bleeding and should be used with caution in patients receiving heparin sodium. To reduce the risk of bleeding, a reduction in the dose of antiplatelet agent or heparin is recommended. 7.3 Other Medications that May Interfere with Heparin Digitalis, tetracyclines, nicotine, antihistamines, or intravenous nitroglycerin may partially counteract the anticoagulant action of heparin sodium. Intravenous nitroglycerin administered to heparinized patients may result in a decrease of the partial thromboplastin time with subsequent rebound effect upon discontinuation of nitroglycerin. Careful monitoring of partial thromboplastin time and adjustment of heparin dosage are recommended during coadministration of heparin and intravenous nitroglycerin. Antithrombin III (human) – The anticoagulant effect of heparin is enhanced by concurrent treatment with antithrombin III (human) in patients with hereditary antithrombin III deficiency. To reduce the risk of bleeding, a reduced dosage of heparin is recommended during treatment with antithrombin III (human).
Contraindications
4 CONTRAINDICATIONS The use of HEPARIN SODIUM in 5% Dextrose Injection is contraindicated in patients with the following conditions: History of heparin-induced thrombocytopenia (HIT) and heparin-induced thrombocytopenia and thrombosis (HITT) [see Warnings and Precautions (5.3) ] Known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Warnings and Precautions (5.7) and Adverse Reactions (6.1) ] In whom suitable blood coagulation tests – e.g., the whole blood clotting time, partial thromboplastin time, etc., – cannot be performed at appropriate intervals (this contraindication refers to full-dose heparin; there is usually no need to monitor coagulation parameters in patients receiving low-dose heparin) [see Warnings and Precautions (5.5) ] Uncontrollable active bleeding state except when this is due to disseminated intravascular coagulation [see Warnings and Precautions (5.2) ] History of heparin-induced thrombocytopenia (HIT) or heparin-induced thrombocytopenia and thrombosis (HITT) ( 5.3 ) Known hypersensitivity to heparin or pork products ( 5.7 ) In whom suitable blood coagulation tests cannot be performed at appropriate intervals ( 5.5 ) Uncontrollable active bleeding state, except when this is due to disseminated intravascular coagulation ( 5.2 )
Overdosage
10 OVERDOSAGE An overdose requires immediate medical attention and treatment. Symptoms Bleeding is the chief sign of heparin overdosage. Easy bruising, petechial formations, nosebleeds, blood in urine or tarry stools may be the first signs or symptoms of a heparin overdose. In the event of symptomatic heparin overdose, consider stopping heparin infusion. Treatment Neutralization of heparin effect: When clinical circumstances (bleeding) require reversal of heparinization, protamine sulfate (1% solution) by slow infusion will neutralize heparin sodium. No more than 50 mg should be administered, very slowly , in any 10 minute period. Each mg of protamine sulfate neutralizes approximately 100 USP Heparin units. The amount of protamine required decreases over time as heparin is metabolized. Although the metabolism of heparin is complex, it may, for the purpose of choosing a protamine dose, be assumed to have a half-life of about 30 minutes after intravenous injection. Ideally, the dose required to neutralize the action of heparin should be guided by blood coagulation tests or calculated from a protamine neutralization test. Because fatal reactions often resembling anaphylaxis have been reported, protamine sulfate should be given only when resuscitation techniques and treatment of anaphylactoid shock are readily available. For additional information, consult the prescribing information for Protamine Sulfate Injection, USP. Blood or plasma transfusions may be necessary; these dilute but do not neutralize heparin.
