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.

Successful oral delivery of poorly water-soluble drugs both depends on the intraluminal behavior of drugs and of appropriate advanced drug delivery systems

In this excellent review article issued from the UNGAP program (European Network on Understanding Gastro-intestinal Absorption-related Process) you will find relevant and up-to-date information on:


Poorly water soluble drugs and the link between physico-chemical properties and solubility, lipophilicity and permeability
Technologies to increase solubility and dissolution rate: salt formation, amorphous solid dispersions, lipid-based formulations
How to avoid precipitation and create a concentration gradient to improve absorption
Methods for modelling the performance such as Molecular Dynamics Simulations
In vitro methods for solubility and dissolution assessments
Methods to explore the absorption in the GI tract: GI concentration-time profile, in vitro digestion, in vitro models coupling dissolution and permeation, mucus diffusion
Impact of molecularly dissolved drug versus apparently dissolved drug (ie in colloidal structure)

Investigation of the permeation enhancer strategy on benzoylaconitine transdermal patch: the relationship between transdermal enhancement strength and physicochemical properties of permeation enhancer

In this study several permeation enhancers are evaluated for their ability to permeate high molecular weight benzoylaconitine. The results showed that Plurol® Oleique CC 497 enabled the highest permeation. FT-IR studies demonstrated that the enhancer had strong interactions with the Stratum corneum, both in the hydrophilic and lipophilic regions. The optimized patch formulation showed excellent analgesic and antiinflammatory effect.

Vithani K, Goyanes A, Jannin V, Basit AW, Gaisford S, Boyd BJ

In this study, the authors show that solid SMEDDS can be produced with a 3D printing  process and solid and semi-solid lipid excipients. The proof of concept is established with cinnarizine and fenofibrate as model drugs.

Colloidal aspects of dispersion and digestion of self-dispersing lipid-based formulations for poorly water-soluble drugs

In this review article, the authors explain the importance of the colloidal structures formed during dispersion and digestion of self emulsifying lipid-based formulations on drug solubilization and absorption.

A review of the techniques used to characterize the colloidal structures is also carried out.
