Heparin calcium is a widely used anticoagulant medication that helps prevent and treat blood clots. For decades, it has played a vital role in saving lives during surgeries and for various medical conditions where blood clotting needs to be stopped or reduced. In this article, we will explore what heparin calcium is, how it works, its uses and benefits, precautions, and more.
What is Heparin Calcium?
Heparin calcium belongs to a class of drugs known as anticoagulants or "blood thinners." It is a glycosaminoglycan that acts as an anticoagulant by inhibiting certain clotting factors in the blood. Chemically, heparin calcium is a salt form of heparin sodium and is comprised of polysaccharide chains made of repeating disaccharide units.
How Does it Work?
Heparin calcium works by binding to and activating antithrombin III, a plasma protease inhibitor. This activated complex then inactivates coagulation enzymes such as thrombin and Factor Xa. By inhibiting these clotting factors, heparin prevents new clots from forming and enlarging existing clots. It works systemically to inhibit both arterial and venous thromboembolism. Importantly, heparin's action is immediate but reversible through binding to antithrombin III.
Uses and Medical Benefits of Heparin Calcium
- Preventing deep vein thrombosis and pulmonary embolism during and after surgeries
- Treating pulmonary embolism, deep vein thrombosis or thromboembolic disorders
- Managing unstable angina or non-Q-wave myocardial infarction
- Used during hemodialysis to prevent clotting in the dialysis circuits
- Preventing clot formation in indwelling catheters or intravenous lines
- Administered during heart attacks to prevent new clots
Routes of Administration
Heparin calcium can be administered via several routes depending on the condition being treated. The most common routes include intravenous injection or infusion, intravenous bolus injection, and subcutaneous injection. For long-term use, subcutaneous injections at set times daily are usually recommended.
Monitoring and Precautions
As heparin acts quickly, regular monitoring of aPTT levels is required to determine dosage adjustments. Over-anticoagulation can lead to bleeds so dosages need careful titration. Risks include bleeding, heparin-induced thrombocytopenia (HIT), osteoporosis with long term use. Patients on heparin also need close monitoring for signs of bleeding and bruising.
Adverse Reactions
- Bleeding from any site - the most serious side effect
- Thrombocytopenia (low platelet count) in case of heparin-induced thrombocytopenia
- Increased risk of osteoporosis and bone loss with long term use
- Skin necrosis or ulceration at injection sites in some patients
- Hyperkalemia (high potassium levels) in rare cases
- Allergic reactions like rashes, itching, hives in sensitive individuals
Drug Interactions
- Other anticoagulants like warfarin increase bleeding risk when used with heparin
- Platelet inhibitors augment the anticoagulant effect and raise bleeding risk
- Non-steroidal anti-inflammatory drugs inhibit platelet function and increase bleeding
- Selective serotonin reuptake inhibitors also pose an increased bleeding risk
Precautions for Special Groups
- Pregnancy: Heparin is considered safe but needs monitoring due to increased bleeding risk
- Kidney disease: Dose adjustments may be needed due to impaired elimination
- Liver disease: Caution is required in patients with hepatic impairment
- Surgery: Withhold heparin prior to elective surgery or dental procedures
- Elderly: Seniors are more prone to adverse effects due to changes in kidney function
