Heparin - Unfractionated heparin (UH) is a heterogenous preparation of anionic, sulfated glycosaminoglycan polymers with weights ranging from 3000 to 30,000 Da. It is a naturally occurring anticoagulant released from mast cells. It binds reversibly to antithrombin III (ATIII) and greatly accelerates the rate at which ATIII inactivates coagulation enzymes thrombin (factor IIa) and factor Xa. UH is different from low molecular weight heparin (LMWH) in the following ways: the average molecular weight of...
Sodium Chloride - Pharmacological action Ions of sodium and chlorine are the major inorganic components of the extracellular fluid, maintaining an appropriate osmotic pressure of blood plasma and extracellular fluid. Isotonic solution of Sodium Chloride fills a deficit of body fluids during dehydration. Hypertonic solution of sodium chloride for IV injection provides a correction of osmotic pressure of extracellular fluid and blood plasma. When applied topically in ophthalmology sodium chloride has...
