🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is not absorbed from the gastrointestinal tract and must be given by injection. After subcutaneous injection, it is absorbed slowly and variably, with bioavailability around 30%. After intravenous injection, it is completely bioavailable.
DistributionThis medicine distributes mainly in the plasma and does not cross the placenta or enter breast milk in significant amounts. It has a volume of distribution of about 0.07 L/kg.
Protein BindingThis medicine is highly bound to plasma proteins, including antithrombin III and other proteins, with a binding rate of about 95%.
MetabolismThis medicine is metabolized in the liver and reticuloendothelial system. It undergoes depolymerization and desulfation.
Half-LifeThe elimination half-life is dose-dependent and ranges from 1 to 2 hours after intravenous administration, but can be longer at higher doses.
ExcretionThis medicine is excreted primarily in the urine as metabolites and unchanged drug.
Bioavailability100% for intravenous route; approximately 30% for subcutaneous route.
Onset of ActionImmediate after intravenous injection; within 20-60 minutes after subcutaneous injection.
Peak Plasma TimeImmediately after intravenous injection; 2-4 hours after subcutaneous injection.
Duration of ActionThe anticoagulant effect lasts for 2-6 hours after intravenous injection, depending on the dose.

How It Works

This medicine works by binding to antithrombin III, a natural anticoagulant protein in the blood. This binding causes a conformational change that dramatically accelerates antithrombin III's ability to inactivate thrombin (factor IIa) and factor Xa. By inhibiting these clotting factors, it prevents the conversion of fibrinogen to fibrin and thus stops clot formation. It also inhibits the activation of factors IX, XI, XII, and plasmin. The effect is immediate when given intravenously and depends on the presence of antithrombin III.

Mechanism Steps

1
Binding to antithrombin III: This medicine binds to antithrombin III, causing a conformational change that exposes its active site.
2
Inactivation of thrombin: The activated antithrombin III rapidly inactivates thrombin, preventing the conversion of fibrinogen to fibrin.
3
Inactivation of factor Xa: It also inactivates factor Xa, reducing the generation of thrombin from prothrombin.
4
Inhibition of clot formation: The overall effect is the prevention of clot formation and the extension of existing clots.

Dosage Information

Adult DosageThe dose of this medicine is highly individualized and depends on the indication, patient weight, and clinical condition. It is given by a healthcare professional. For therapeutic anticoagulation, a common regimen is an initial intravenous bolus of 5000-10000 IU followed by a continuous infusion of 1000-2000 IU per hour, adjusted to maintain aPTT at 1.5-2.5 times control. For prophylactic use, 5000 IU subcutaneously every 8-12 hours may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the anticoagulant effects of this medicine and are at higher risk of bleeding. Doses should be carefully adjusted based on renal function and clinical response. Close monitoring is required.
Renal ImpairmentIn patients with renal impairment, the elimination of this medicine may be prolonged. Dose reduction and close monitoring of aPTT are recommended. Consult a clinician for specific dosing.
Hepatic ImpairmentIn patients with severe hepatic impairment, the effect of this medicine may be enhanced due to reduced synthesis of clotting factors. Use with caution and monitor closely.
Maximum Daily DoseThe maximum daily dose is not fixed and depends on the clinical situation. It must be determined by a qualified clinician.
