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

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

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.

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.

Toward improving the in vitro in vivo correlation of lipid-based formulations using a simplified gastro-intestinal lipolysis protocol

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.

Lipid-based excipients, which are often liquid at room temperature, can enhance solubility and permeation. This study aims to incorporate a liquid lipid excipient into a solid dosage form for the poorly water-soluble drug ondansetron hydrochloride dihydrate (OHD).

Comparing the effect of adding Gelucire® 48/16 and Gelucire® 50/13 in amorphous solid dispersion: a case study with ticagrelor

Lolie Chéron, Cédric Miolane, Philippe Caisse

When amorphous solid dispersion (ASD) are produced by hot melt extrusion (HME), the use of a neat polymer requires high process temperatures, and the drug release is not always complete. Adding Gelucire® in the formula is a promising strategy to address these issues.

Rheology as a tool for characterizing topical product formulations: impact of solubilizer variation on stability and structure

  • Poster

CRS - jui 2024

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

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.

Implementation of an at-line nanoparticle size analyzer in a continuous nano-manufacturing line considering critical measurement and process conditions
