Wirkstoffmatrix in Form eines biologisch resorbierbaren porösen Vlieses, Verfahren zu ihrer Herstellung und Verwendung

摘要

The invention relates to an active ingredient matrix in the form of a biologically resorbable porous non-woven made of collagen fibrils in a dry frozen state with delayed release of said active ingredients. The matrix contains at least one homogeneously divided active ingredient that is difficultly soluble in water and body fluids. A difficultly soluble active ingredient in a finely divided form is added to a collage suspension produced in a certain manner in order to produce the inventive active ingredient matrix.
