Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Apart from using unfractionated heparin instead, it may be possible to reduce the dose and/or monitor the anti-Xa activity to guide treatment. [3] The most common side effects include bleeding, which could be severe or even fatal, allergic reactions, injection site reactions, and increases in liver enzyme tests, usually without symptoms.

Side effects from intra-articular administration can include joint pain, swelling, lameness, and, rarely, infection of the joint. Intramuscular injection can cause dose-dependent inflammation and bleeding, since PSGAG is an analogue of the anticoagulant heparin. [4] In dogs, this may manifest as bleeding from the nose or as bloody stools. [7]
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
Heparin may be used for both prevention and the treatment of thrombosis. It exists in two main forms: an "unfractionated" form that can be injected under the skin (subcutaneously) or through an intravenous infusion, and a "low molecular weight" form that is generally given
Dalteparin is not superior to unfractionated heparin in preventing blood clots. [5] Heparins are cleared by the kidneys, but studies have shown that dalteparin does not accumulate even if kidney function is reduced. [6] Approximately 70% of dalteparin is excreted through kidneys based on animal studies. [7]
Endogenous heparin is localized and stored in secretory granules of mast cells. Histamine that is present within the granules is protonated (H 2 A 2+ ) at pH within granules (5.2–6.0), thus it is believed that heparin, which is highly negatively charged, functions to electrostatically retain and store histamine.

Parnaparin is an antithrombotic and belongs to the group of low molecular weight heparins.In the prevention and therapy of thromboembolic pathologies, the advent of this class of drugs represented a medical development, since they retain the same effectiveness of unfractionated heparin but with simpler dosing regimens and decreased side effects.
