Toward improving the in vitro in vivo correlation of lipid-based formulations using a simplified gastro-intestinal lipolysis protocol
AAPS - Oct 2024
Lipid-based formulations (LBF) enhance the oral bioavailability of poorly water-soluble drugs by maintaining them in a solubilized state during digestion. This study aims to establish a robust protocol to evaluate the impact of gastro-intestinal lipolysis on LBF performance, using cinnarizine as a model drug.
Rheology as a tool for characterizing topical product formulations: impact of solubilizer variation on stability and structure
CRS - Jul 2024
The use of solubilizers in a topical formulation helps solubilization of poorly soluble APIs. Therefore, it is essential to have a formulation chassis that can be modulated to incorporate this quantity of solubilizer. In this poster, the influence of different excipients as solubilizers and their variation on the stability and rheological properties of topical creams is investigated.
Formulation forum – A Quick Approach for Evaluation of Drug-Excipient Compatibility: Case of Acetylsalicylic Acid
Drug Development & Delivery - 2021
In this study, the authors monitor acetylsalicylic acid (ASA) hydrolysis in different formulations using UPLC and TAM with the objective of comparing these methods for agreement, speed, and efficiency in predicting drug stability. In parallel, we assess the impact of the excipient choices on the stability of the ASA.

TAM Technique for Identifying API-Lipid Excipient Compatibility Issues Upstream in the Development Process
AAPS PharmSci 360 – Washington DC (USA) - Nov 2018
In this study the authors showed that Thermal Activity Monitoring is a useful technique to detect at early stage potential interaction between APi and excipients, using less time and resources than conventional techniques.
TAM technique is used routinely in Gattefossé North America Technical Center of Excellence to speed up formulation development.
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 - Feb 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.
