Unfractionated Heparin

Unfractionated Heparin Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Unfractionated Heparin is a brand name. Its generic name is Heparin.

Unfractionated Heparin Introduction

Unfractionated Heparin is a blood-thinning medication, also known as an anticoagulant, which helps prevent the formation of blood clots. It is used to prevent and treat a wide variety of conditions in which clots can be a problem, such as deep vein thrombosis (DVT), pulmonary embolism (PE), myocardial infarction (heart attack) and stroke. It is also used to prevent clot formation in extracorporeal circulation of blood in patients undergoing heart surgery. It is available in different forms, such as injections, intravenous and subcutaneous injections, and topical.

Uses for Unfractionated Heparin

Unfractionated Heparin is used to prevent and treat a wide variety of conditions in which clots can be a problem, such as deep vein thrombosis, pulmonary embolism, myocardial infarction (heart attack) and stroke. It can also be used to prevent clot formation during open heart surgery, dialysis and other extracorporeal circulation of blood.

Mechanism of Action

The mechanism of action of heparin is not completely understood, but it is thought to work by inhibiting the action of thrombin, an enzyme involved in clot formation. Unfractionated Heparin binds to and inactivates thrombin, thereby preventing the conversion of fibrinogen to fibrin and the formation of a clot. By inhibiting thrombin, heparin also reduces the activity of Factors Xa and XIa, two other enzymes involved in clot formation.

How Long Does It Take to Work?

The time it takes for heparin to work depends on the dose and type of heparin used. Low molecular weight heparin (LMWH) begins to work within minutes, while unfractionated heparin (UFH) begins to work within 30 minutes to 4 hours. The effects of heparin can last for several days.

Absorption

Unfractionated Heparin is not absorbed from the gastrointestinal (GI) tract and is given only by intravenous, subcutaneous or topical routes of administration.

Route of Elimination

Unfractionated Heparin is quickly eliminated from the body by the kidneys. The majority of a dose is excreted within 6 hours of administration.

Dosage, Administration, Side Effects, Toxicity

Unfractionated Heparin is available in different forms, including intravenous, subcutaneous, and topical, and in different doses depending on the indication. It is usually given as an injection into a vein (IV) and may also be given as a subcutaneous injection (under the skin). Side effects of heparin may include bleeding, bruising, and pain at the injection site. Other side effects can include nausea, vomiting, dizziness, headache, and low blood pressure. In rare cases, heparin can cause a severe, life-threatening allergic reaction (anaphylaxis) in which the body goes into shock.

Precautions

Unfractionated Heparin should be used with caution in people with kidney or liver disease and those who are pregnant or breastfeeding. It should not be used in people with active bleeding disorders, as it can increase the risk of bleeding. People taking heparin should discuss all their medications with their healthcare provider, as some drugs can interact with heparin and increase the risk of bleeding. In addition, heparin should not be taken within 14 days of any surgery.

Interactions

Unfractionated Heparin can interact with other drugs, including aspirin, warfarin, and certain antibiotics. Therefore, it is important to tell your healthcare provider about all the medications you are taking, including over-the-counter and herbal medications. In addition, heparin can interact with certain supplements and foods, so it is important to tell your healthcare provider about all supplements and foods you are consuming, including herbal or natural remedies.

Disease Interactions

Unfractionated Heparin is contraindicated in people with active bleeding disorders, as it can increase the risk of bleeding. People with kidney or liver disease should also use heparin with caution, as these conditions can decrease the body’s ability to excrete heparin. In addition, heparin should be used with caution in people with cystic fibrosis, as this condition can increase the risk of bleeding.

Drug Interactions

Unfractionated Heparin can interact with other drugs, including aspirin, warfarin, and certain antibiotics (e.g., ampicillin, cephalosporins). Other drugs that can increase the risk of bleeding, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and anticoagulants, should also be used with caution while taking heparin.

Food Interactions

Unfractionated Heparin can interact with some foods, including green leafy vegetables, which contain vitamin K. Eating foods that are high in vitamin K can make heparin less effective, so it is important to discuss your diet with your healthcare provider. In addition, eating foods that are high in dietary fiber, such as beans and whole grains, can cause heparin to be less effective.

Pregnancy Use

Unfractionated Heparin is generally considered safe for use during pregnancy, but it should be used with caution as there may be an increased risk of bleeding in pregnant women. It should not be used in pregnant women with active bleeding disorders or those with a risk of complications from bleeding, such as pre-eclampsia or eclampsia.

Lactation Use

Unfractionated Heparin is generally considered safe for use while breastfeeding, but it should be used with caution as there may be an increased risk of bleeding in lactating women. It should not be used in lactating women with active bleeding disorders or those with a risk of complications from bleeding, such as pre-eclampsia or eclampsia.

Acute Overdose

In case of an acute overdose of heparin, seek immediate medical attention. Symptoms may include severe bleeding, which may require blood transfusion or surgery. Treatment may include monitoring for bleeding, administration of fresh frozen plasma and other clotting factors, and dialysis for elimination of heparin from the body.

Contraindications

Unfractionated Heparin is contraindicated in people with active bleeding disorders, as it can increase the risk of bleeding. It is also contraindicated in people with a risk of complications from bleeding, such as pre-eclampsia or eclampsia. In addition, heparin should not be used within 14 days of any surgery.

Use Direction

Unfractionated Heparin injections should be given by a healthcare provider or by a person trained in its administration. It should be given either intravenously (into a vein) or as a subcutaneous injection (under the skin). Injections should be given at the same time each day or as instructed by your healthcare provider.

Storage Condition

Unfractionated Heparin should be stored at room temperature, away from heat and moisture, and out of reach of children. It should not be exposed to extremes of temperature or direct sunlight.

Volume of Distribution

The volume of distribution of heparin is 0.6-0.8L/kg. This means that a dose of heparin is distributed evenly throughout the body.

Half Life

The half-life of heparin depends on the heparin used. Unfractionated heparin (UFH) has a half-life of about 1 hour, while low molecular weight heparin (LMWH) has a half-life of approximately 4-5 hours. The half-life can also be affected by kidney and/or liver function.

Clearance

Unfractionated Heparin is quickly cleared from the body by the kidneys. The majority of a dose is excreted within 6 hours of administration.

Dosage Information

The dosage of heparin depends on the indication, route of administration, and type of heparin. For intravenous (IV) administration, the dose is usually lower than for subcutaneous (SC) administration. Low molecular weight heparin (LMWH) has a higher bioavailability than unfractionated heparin (UFH), so a lower dose is required. SC administration has a slower onset of action than IV, but the effects are longer lasting. The usual dose of heparin is 2,500-10,000 units/day for IV and 3,000-20,000 units/day for SC. Your healthcare provider may adjust the dose depending on your condition.
