This study highlights that combining offline, at-line, in-line, and online DLS methods enables thorough monitoring across the entire lipid nanoparticles production process. This integrated approach streamlines operations, supports real-time process adjustments, and ensures dependable quality control both post-production and during storage.

In Vitro In Silico Correlation of Lidocaine HCl Skin Permeation - A Comparative Study of Gel Cream and Bigel formulations

  • Poster

ECP - Mar 2025

Manon Rossano, Delphine Pélisson, Malaury Ducros, Elise Dauphin-Chanard, Philippe Caisse

In this work, the effectiveness of Skin-in-Silico™ software for simulating dermal absorption and permeation of lidocaine hydrochloride in gel, cream, and bi-gel forms was evaluated. By combining in silico predictions with in vitro experiments, we explore the correlation between these methods and their role in optimizing topical drug formulations.

  • Scientific publication

Molecules - Jan 2025

Alessio Gaggero, Viktoria Marko, Dalibor Jeremic, Carolin Tetyczka, Philippe Caisse, Jesús Alberto Afonso Urich

This article showcases the development and validation of a robust UPLC-ELSD method, using analytical Quality-by-Design principles, to accurately quantify medium-chain triglycerides in a lipid-based excipient for nanoemulsion applications, ensuring compliance with regulatory standards.

Understanding Microemulsions and Nanoemulsions in (Trans)Dermal Delivery

  • Scientific publication

AAPS PharmSciTech - Jan 2025

Jasmine Musakhanian, David W. Osborne

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.

Bigels: case studies of an innovative topical dosage form

  • Poster

ABCF Congress - Nov 2024

Delphine Pélisson, Manon Rossano, Paulo Cunha, Kelly Bueno, Philippe Caisse, Elise Dauphin-Chanard

Adherence to treatments is a key challenge for topical formulations. Bigels, formulated with Emulfree® Duo are an innovative dosage form that can combine both hydrophilic and lipophilic active ingredients in a stable, moisturizing, and easily spreadable formulation. This study showcases three different placebo bigels formulations.
