Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans possessing anticoagulant properties. It is composed of polymers of alternating derivations of α-D-glucosamido ( N -Sulfated O -Sulfated or N -acetylated) and O -sulfated uronic acid (α-L-iduronic acid or β-D-glucoronic acid). Structure of Heparin Sodium (representative subunits): HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION is a sterile preparation of heparin sodium (derived from porcine intestinal mucosa) for intravenous administration. It contains no bacteriostatic or antimicrobial agent or added buffer. The solution may contain sodium hydroxide and/or hydrochloric acid for pH adjustment. The pH range is 6.1 (5.0 – 7.5) and the osmolarity mOsmol/L (calc.) is 155. The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram. Each mL of the 50 USP Units per mL preparations contains: 50 USP Units of heparin sodium, 4.5 mg sodium chloride and 0.1 mg edetate disodium, anhydrous added as a stabilizer. Each mL of the 100 USP Units per mL preparations contains: 100 USP Units of heparin sodium, 4.5 mg sodium chloride and 0.1 mg edetate disodium, anhydrous added as a stabilizer. structural formula for heparin
