Unfractionated heparin (UFH) is a natural protein in human body which supports to thin the blood by combining with antithrombin.  Unfractionated heparin binds to antithrombin, which enhances the ability of inhibiting the most potential clotting factors in the body, which are factor Xa and factor IIa, within minutes. Unlike other heparins that break the clot, unfractionated heparin inhibits the formation of new clots. This allows the body to dissolve the existing blood clots.

Unfractionated heparin (UFH) is highly preferred for patients at high risk of bleeding complications due to its short activity and reversibility. It is less dependent on the kidneys for excretion when compared to other heparins, which makes it the choice for morbidly obese patients, underweight patients, and known or potential renal diseases. This heparin has more advantages than disadvantages, which makes it more potential heparin than others. Advantages such as rapid access in the blood stream, which prevents clot formation. . It quickly diminishes when the infusion or injections are stopped and it is the most cost-effective heparin formulation when compared to others. These factors are expected to drive growth of the U.S. unfractionated heparin market over the forecast period.

Market Dynamics

The U.S. unfractionated heparin market is expected to witness significant growth over the forecast period, owing to increasing incidence of thromboembolic disorders. For instance, as per the data published by the Centers for Disease Control and Prevention (CDC) in February 2018, 900,000 people are affected (1 to 2 per 1,000) each year with deep venous thromboembolism and pulmonary embolism (DVT/PE) in the U.S.

Favorable regulatory framework for unfractionated heparin is also expected to drive the market growth. For instance, American Society of Health-System Pharmacists (ASHP) issued a policy for safe and effective use of heparin in neonatal patients. This policy was reviewed and approved in 2014 by the Council on Therapeutics and by the Board of Directors. The policy supported development and use of nationally standardized concentrations of heparin while using for maintenance and flush of peripheral and central venous lines in neonatal patients.
