This study explores the use of 3D printing, specifically fused deposition modeling (FDM), for personalized medicine by combining lipids and cellulosic excipients like hypromellose (HPMC). Hot-melt extrusion (HME) is employed to create filaments, with a focus on balancing processing temperatures and mechanical properties.

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

  • Poster

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.

Veterinary soft chews using Gelucire® 50/13 and Precirol® ATO 5. A proof of concept with wet extrusion

Fleur Guénard, Cécile Morin, Ceren Yuece, Philippe Caisse

This study aims to demonstrate the effectiveness of Gelucire® 50/13, a surfactant, and Precirol® ATO 5, a taste-masking agent, in producing veterinary soft chews using a wet extrusion process. These ingredients enable the development of high-drug load formulations with taste-masking capabilities and customizable drug release profiles, making them ideal for this innovative dosage form.

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.
