🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to antithrombin III, a natural protein in the blood that inhibits clotting factors. This binding enhances antithrombin III's ability to inactivate factor Xa, a key enzyme in the coagulation cascade. By inhibiting factor Xa, this medicine reduces the conversion of prothrombin to thrombin, thereby decreasing fibrin formation and clot development. It has a higher ratio of anti-factor Xa to anti-factor IIa activity compared to unfractionated heparin, which makes its anticoagulant effect more predictable and reduces the need for frequent monitoring.

Strength: Injection: 4500 IU per 0.45 mL (as tinzaparin sodium)
Dosage Information
| Adult Dosage | The dose of this medicine varies depending on the indication. For prophylaxis of deep vein thrombosis, a common dose is 4500 IU subcutaneously once daily. For treatment of DVT or PE, the dose is based on body weight, typically 175 IU/kg subcutaneously once daily. For hemodialysis, the dose is individualized based on the procedure. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may have reduced renal function and are at higher risk of bleeding. Dose adjustment may be necessary based on renal function. Monitor closely. |
| Renal Impairment | In patients with severe renal impairment (creatinine clearance <30 mL/min), the dose may need to be reduced or the medicine avoided, especially for treatment doses. Consult a clinician for individualized dosing. |
| Hepatic Impairment | No specific dose adjustment is established for hepatic impairment. Use with caution and monitor for bleeding. |
| Maximum Daily Dose | The maximum daily dose depends on the indication and patient factors. For treatment, doses up to 175 IU/kg once daily are used. Do not exceed the prescribed dose. |
