Therapeutic indications

Hirudoid is indicated for the treatment of superficial thrombophlebitis and the soothing relief of superficial bruising and haematoma.

Pharmacodynamic properties

Heparinoid 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).

Pharmacokinetic properties

Radiochemical studies of absorption following cutaneous application of heparinoid (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.
