In this study Labrasol® ALFwas investigated as an intestinal permeation enhancer in isolated rat colonic mucosae in Ussing chamber and in rat in situ intestinal instillations.

Labrasol® ALF (4 and 8 mg/mL) enhanced the transport of the paracellular markers  across colonic mucosae. The enhancement was non-damaging, transient, and molecular weight-dependent.
