5. Pharmacological Properties

5.1 Pharmacodynamic Properties

Mucopolysaccharide polysulphate ester is recognised as having:

A weak inhibitory effect on PGE₂ synthesis and an indirect effect on LTB₄ production based on in vitro studies.

Anti-coagulant activity: as a heparinoid.

Thrombolytic activity: through potentiation of urokinase activity.

Anti-exudatory activity: through inhibition of hyaluronidase.

Oxypolyethoxydodecane has both topical anaesthetic and anti-pruritic properties.

5.2 Pharmacokinetic Properties

Radiochemical studies of absorption following cutaneous application of mucopolysaccharide polysulphate have shown that between 0.3 and 4% of the mucopolysaccharide administered is absorbed by various tissues (other than the treated area) within the first 8 hours. Typically between 1.7% and 4.6% will be absorbed within 2 to 4 days. Animal studies have also shown that mucopolysaccharide is bound intracellularly within the subcutis. Peak serum concentrations following cutaneous application are below the threshold of physiological relevance for coagulation.

Mucopolysaccharide is excreted in the urine partly unchanged and partly as depolymerized, shorter chain length molecules.
