Introduction
In general, sodium enoxaparin refers to enoxaparin sodium injection, which does not require air expulsion. Enoxaparin sodium injection is an anticoagulant commonly used for the prevention and treatment of deep vein thrombosis and pulmonary embolism. Due to its small volume and high cost, expelling air bubbles can lead to wastage of the medication and inaccurate dosing.
Under normal circumstances, enoxaparin sodium refers to enoxaparin sodium injection, which does not require air expulsion before use. Enoxaparin sodium injection is an anticoagulant commonly used for the prevention and treatment of deep vein thrombosis and pulmonary embolism. The detailed explanation is as follows:
Enoxaparin sodium injection works by inhibiting coagulation factors in the blood. The injection device comes as a pre-filled syringe, a ready-to-use single-dose system that requires no preparation or drawing medication from a vial. Each syringe contains approximately 0.1–0.2 mL of air, which does not need to be expelled. This is because enoxaparin sodium injection has a small volume and is relatively expensive; expelling the air bubble may lead to wastage of the medication and inaccurate dosing. Additionally, retaining the air bubble helps ensure complete delivery of the drug into the body. After injection, the air bubble can seal the subcutaneous space, preventing leakage of medication from the injection site and reducing local bleeding at the puncture site.
If patients experience any discomfort, they should seek timely medical attention at a hospital to avoid delays in diagnosis and treatment.
