Polidocanol is a sclerosing agent indicated to treat uncomplicated spider veins and uncomplicated reticular veins in the lower extremity.
- Associated Conditions
Polidocanol has a concentration and volume dependent damaging effect on the blood vessel endothelium.
- Mechanism of action
When administered, polidocanol locally damages blood vessel endothelium. Following the endothelial damage, platelets aggregate at the site and attach to the venous wall eventually resulting in a dense network of platelets, cellular debris, and fibrin that occludes the vessel. Eventually the vessel is replaced by connective fibrous tissue.
When given intravenously, the maximum blood concentrations were reached in 15 mins.
- Volume of distribution
When given intravenously, the volume of distribution was 35-82L.
- Protein binding
Plasma protein binding was not measured.
Metabolism was not measured.
- Route of elimination
Route of elimination was not indicated.
- Half life
The half-life is approximately 1.5 h.
Sytemic clearance was 0.2-0.4 L/min.
Most adverse reactions are related to the intravenous administration such as local irritation, pain, and hematoma. Extravasation can also be an issue.
