The heparin-related health crisis in — called for better ways of manufacturing safe, anticoagulant heparin. In addition, there is a growing concern about a shortage of porcine heparin given the enormous number of animals that must be slaughtered in order to meet the current need.
To this end, effort has been directed towards developing and improving techniques and approaches towards the synthesis of heparin as described above. To date, some degree of success has been achieved. However, more work is required in specific approaches including improving anticoagulant profiles of the engineered heparinoids, improved scalability for better yield, more preclinical and clinical trials to establish efficacy and safety profiles.
The specific structures responsible for the anticoagulant properties of heparin have been studied. Several chemical, chemoenzymatic, and metabolic engineering techniques for structural modification of heparin have also been developed over the years, again with varying degrees of success.
Moreover, more studies will be required both at the preclinical and clinical stages to study the in vivo effects of these heparin- and HS-like molecules to determine their pharmacokinetic and safety profiles. In conclusion, within a century of its discovery, heparin has been successfully applied in several clinical scenarios and continues to be one the most commonly used anticoagulants today.
Several advances have been made towards understanding the mechanisms of action and spectrum of its biological activities. New insight has also been gained into potential ways for bioengineering and synthesis of heparin and heparin-like molecules geared towards meeting the current need for safety and mitigating the concern for shortages in the current supply. In spite of these advances, there remain opportunities for improvement.
Surface modification of nanoparticles with heparin can also be used for diagnostic and therapeutic purposes in the field of oncology, although nanomedicine in general is an emerging field and more research into safety and efficacy are still required both at the preclinical and clinical levels.

Abstract Heparin, the most widely used anticoagulant drug in the world today, remains an animal-derived product with the attendant risks of adulteration and contamination. Keywords: heparin, heparan sulfate, heparin-like molecules, bioengineering, UFH, low molecular weight heparin, anti-inflammatory, antitumor, Chinese hamster ovary cells.
History and Background Heparin is the oldest anticoagulant used in clinical medicine. Open in a separate window. Figure 1. Figure 2. Chemoenzymatic Approaches Successful chemical synthesis of heparin and related substances is manifest in the drug fondaparinux, a synthetic analog of the pentasaccharide sequence for AT binding required for Factor Xa inhibition. Novel Applications of Heparin Apart from its use as an anticoagulant, over the years there has been growing interest in the potential applications of heparin for other purposes.
Inflammatory and Allergic Disorders Interest in the anti-inflammatory effects of heparin dates back several decades. Malignancies The potential role of heparin in the management of malignancy has been under investigation in recent decades. Infectious Diseases The potential application of heparin derivatives in the field of infectious disease is less studied compared to inflammatory and oncologic conditions.
Heparin Molecules as Nanocarriers for Drug Delivery Due to the antitumor properties of heparin, there is a growing interest in the use of heparin for functionalization of nanocarriers for targeted drug delivery in cancer treatment. Structural Modifications of Heparin to Achieve Better Profile for Non-Anticoagulant Functions Different modifications of heparin and HS molecules influence the spectrum of their anticoagulant, antitumor, and anti-inflammatory properties.
Future Perspectives and Directions Heparin is a naturally occurring substance with several identified physiologic properties and potential for more diverse applications than currently employed.

What special dietary instructions should I follow? What should I do if I forget a dose? What side effects can this medication cause? What should I know about storage and disposal of this medication?
Brand names. Other uses for this medicine. What special precautions should I follow? Before using heparin, tell your doctor and pharmacist if you are allergic to heparin, any other medications, beef products,pork products, or any of the ingredients in heparin injection.
Ask your doctor or pharmacist for a list of the ingredients. Be sure to mention any of the following: other anticoagulants such as warfarin Coumadin ; antihistamines in many cough and cold products ; antithrombin III Thrombate III ; aspirin or aspirin-containing products and other nonsteroidal anti-inflammatory drugs NSAIDs such as ibuprofen Advil, Motrin and naproxen Aleve, Naprosyn ; dextran; digoxin Digitek, Lanoxin ; dipyridamole Persantine, in Aggrenox ; hydroxychloroquine Plaquenil ; indomethacin Indocin ; phenylbutazone Azolid not available in the US ; quinine; and tetracycline antibiotics such as demeclocycline Declomycin , doxycycline Monodox, Vibramycin , minocycline Dynacin, Minocin and tetracycline Bristacycline, Sumycin.
Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Your doctor may tell you not to use heparin. Also tell your doctor if you have or have ever had a bleeding disorder such as hemophilia condition in which the blood does not clot normally , antithrombin III deficiency condition that causes blood clots to form , blood clots in the legs, lungs, or anywhere in the body, unusual bruising or purple spots under the skin, cancer, ulcers in the stomach or intestine, a tube that drains the stomach or intestine, high blood pressure, or liver disease.
If you become pregnant while using heparin, call your doctor. Smoking may decrease the effectiveness of this medication. Unless your doctor tells you otherwise, continue your normal diet.
Heparin may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away: redness, pain, bruising, or sores at the spot where heparin was injected hair loss Some side effects can be serious.
