Systemic and Local Diffusion of Ethanol After Administration of Ethanol 96% Formulated in a Gel and Ethanol 98% Solution by the Percutaneous Route, in Patients With Congenital Venous Malformations:Pharmacokinetic, Pharmacodynamic and Clinical Study.

Completed · Phase 2

Conditions studied: Congenital Venous Malformation

In brief

Absolute ethanol has been used "off-label" as an unmodified formulation (solution) in Congenital Venous Malformations (CVM). Despite its effectiveness, absolute ethanol appears difficult to handle because of its high diffusion capacity outside the CVM and in the blood circulation. A less diffusible ethanol-based product (ethanol gel) has been developed in order to minimize systemic and local diffusion capacities of ethanol. Therefore, the pharmacokinetic parameters and their clinical and paraclinical outcomes between ethanol gel 96% and absolute ethanol need to be carried out.
