Meitheal Pharmaceuticals Announces Launch of Heparin Sodium Injection, USP in the United States 

Chicago, Ill. – September 12, 2019 – Meitheal Pharmaceuticals (“Meitheal”), a fully integrated generic injectables company today announced the launch of the Company’s eight presentations of heparin sodium injection, USP in the United States (US).


“We are pleased to be able to provide a vital anticoagulant for patients across the country,” said Tom Shea, founding Chief Executive Officer of Meitheal Pharmaceuticals. “With increasing challenges in manufacturing and supply concerns in the global heparin market, our launch will help provide additional product for patients from a safe and dependable source. We take pride in offering a vertically integrated heparin portfolio in the US, and our operations are optimized to ensure dedicated manufacturing of heparin and consistent supply of the finished product to the US market.”  


Meitheal’s partner, Nanjing King-Friend Biochemical Pharmaceutical Company (NKF) is an FDA-approved manufacturer of both active pharmaceutical ingredients (API) and finished dosage form (FDF), supplying 15-20% of the finished dosage heparin market in the US. Meitheal is NKF’s exclusive commercialization arm for the US market, ensuring consistent and dedicated supply of heparin.


Meitheal primarily specializes in the development, manufacture, procurement, and sale of generic injectable pharmaceuticals, with 12 FDA-approved products covering indications for anti-infective, oncolytic and intensive care. Furthermore, Meitheal has an expanding product portfolio and robust pipeline, including single and multi-dose vials, ready-to-use prefilled syringes and premixed bags. As of the end of June 2019, Meitheal, directly or in combination with its partner(s), had 49 products in the research and development phase, 24 products under review by the FDA, and 8 products to be launched in 2019.


Heparin is an intravenous or subcutaneous anticoagulant derived from porcine intestinal mucosa used to decrease the clotting ability of blood and help prevent harmful clots from forming in blood vessels. It is indicated for:

  • Prophylaxis and treatment of venous thrombosis and pulmonary embolism.
  • Prevention of postoperative deep venous thrombosis and pulmonary embolism in patients undergoing major abdominothoracic surgery or who, for other reasons, are at risk of developing thromboembolic disease.
  • Atrial fibrillation with embolization.
  • Treatment of acute and chronic consumptive coagulopathies (disseminated intravascular coagulation).
  • Prevention of clotting in arterial and cardiac surgery.
  • Prophylaxis and treatment of peripheral arterial embolism.
  • Use as an anticoagulant in blood transfusions, extracorporeal circulation, and dialysis procedures.


Heparin Sodium Injection, USP is contraindicated in patients with history of Heparin-Induced Thrombocytopenia (HIT) and Heparin-Induced Thrombocytopenia and Thrombosis (HITT), known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions), those whom suitable blood coagulation tests, e.g., the whole blood clotting time, partial thromboplastin time, etc., cannot be performed at appropriate intervals, and patients with uncontrolled active bleeding state, except when this is due to disseminated intravascular coagulation. 

Fatal Medication Errors: Do not use Heparin Sodium Injection as a “catheter lock flush” product. Heparin Sodium Injection is supplied in vials containing various strengths of heparin, including vials that contain a highly concentrated solution of 10,000 units in 1 mL. Fatal hemorrhages have occurred in pediatric patients due to medication errors in which 1 mL Heparin Sodium Injection vials were confused with 1 mL “catheter lock flush” vials. Carefully examine all Heparin Sodium Injection vials to confirm the correct vial choice prior to administration of the drug. 

Hemorrhage: Avoid using heparin in the presence of major bleeding, except when the benefits of heparin therapy outweigh the potential risks. 

Heparin-Induced Thrombocytopenia and Heparin-Induced Thrombocytopenia and Thrombosis: Heparin-induced thrombocytopenia (HIT) is a serious antibody-mediated reaction. HIT occurs in patients treated with heparin and is due to the development of antibodies to a platelet Factor 4-heparin complex that induce in vivo platelet aggregation. HIT may progress to the development of venous and arterial thromboses, a condition referred to as heparin-induced thrombocytopenia with thrombosis (HITT). 

Thrombocytopenia: Thrombocytopenia in patients receiving heparin has been reported at frequencies up to 30%. It can occur 2 to 20 days (average 5 to 9) following the onset of heparin therapy. Obtain platelet counts before and periodically during heparin therapy. Monitor thrombocytopenia of any degree closely. If the count falls below 100,000/mm3 or if recurrent thrombosis develops, promptly discontinue heparin, evaluate for HIT and HITT, and, if necessary, administer an alternative anticoagulant.  

Coagulation Testing and Monitoring: When using a full dose heparin regimen, adjust the heparin dose based on frequent blood coagulation tests. If the coagulation test is unduly prolonged or if hemorrhage occurs, discontinue heparin promptly [see Overdosage (10)]. Periodic platelet counts and hematocrits are recommended during the entire course of heparin therapy, regardless of the route of administration. 

Heparin Resistance: Resistance to heparin is frequently encountered in fever, thrombosis, thrombophlebitis, infections with thrombosing tendencies, myocardial infarction, cancer, in postsurgical patients, and patients with antithrombin III deficiency. Close monitoring of coagulation tests is recommended in these cases. Adjustment of heparin doses based on anti-Factor Xa levels may be warranted.  

Hypersensitivity Reactions: Patients with documented hypersensitivity to heparin should be given the drug only in clearly life- threatening situations. Because Heparin Sodium Injection is derived from animal tissue, it should be used with caution in patients with a history of allergy.  

Benzyl Alcohol Toxicity: Use preservative-free heparin sodium in neonates and infants. The preservative benzyl alcohol has been associated with serious adverse events and death in pediatric patients. The minimum amount of benzyl alcohol at which toxicity may occur is not known. Premature and low-birth weight infants may be more likely to develop toxicity.

Most common adverse reactions are hemorrhage, thrombocytopenia, HIT and HITT, hypersensitivity reactions, and elevations of aminotransferase levels.
