The invention relates to a method for coating a vascular endoprosthesis wherein the vascular endoprosthesis is at least partially wetted with a first solution of an active substance and the areas of the vascular endoprosthesis that are wetted with the first solution of the active substance are at least partially wetted with a liquid containing water and/or at least one alcohol. The additional wetting with a liquid containing water/alcohol has the effect that the layer of active substance acquires another property namely becoming less transparent and varnish like and instead more chalk like and non transparent. It has been found that such a layer of active substance ensures an improved transfer of the active substance to the vessels into which the vascular endoprosthesis is implanted.
