Understanding Microemulsions and Nanoemulsions in (Trans)Dermal Delivery
AAPS PharmSciTech - jan 2025
Microemulsions and nanoemulsions are explored in pharmaceuticals for their potential in delivering clinically relevant drug doses across biological membranes. Despite extensive literature, there's a lack of clear distinctions between the two in terms of definitions and mechanisms: this review aims to uncover less obvious yet important mechanisms in transdermal drug delivery.
Labrafac™ MC60 is an efficacious intestinal permeation enhancer for macromolecules: Comparisons with Labrasol® ALF in ex vivo and in vivo rat studies
International Journal of Pharmaceutics - jui 2024
In this article, demonstration on how Labrafac™ MC60 acts as a safe intestinal permeation enhancer is given, with insulin as a model molecule. Studies were conducted in vivo and ex vivo, using isolated muscle-stripped rat jejunal and colonic mucosae.
Size characterization of lipid-based self-emulsifying pharmaceutical excipients during lipolysis using Taylor dispersion analysis with fluorescence detection
International Journal of Pharmaceutics, Volume 537, Issues 1–2, Pages 94–101 - fév 2018
In this work, the lipolysis of Labrasol® and Gelucire® 44/14 , two lipid based self-emulsifying drug delivery systems, by pancreatic enzymes and under conditions mimicking the gastrointestinal tract is followed by Taylor dispersion analysis. Results show that, Labrasol® droplets decrease exponentially in size with lipolysis time, whereas Gelucire® 44/14 droplets increased sigmoïdally in size. Even after 120 min lipolysis, both systems maintain a solubilizing capacity of the hydrophobic marker.
Hydrodynamic size characterization of a self-emulsifying lipid pharmaceutical excipient by Taylor dispersion analysis with fluorescent detection
International Journal of Pharmaceutics, Volume 513, Issues 1–2, Pages 262-269 - nov 2016
In this study the size of microemulsion droplets is carried out using Tailor Dispersion Analysis in comparison to Dynamic Light Scattering. The size evolution of a Labrasol® self emulsifying drug delivery system as a function of concentration and temperature is evaluated. The influence of physical parameters and polydispersity is discussed.
