Eur J Pharm Sci. 2019 Oct 1;138:105009. doi: 10.1016/j.ejps.2019.105009. Epub 2019 Jul 12. - Jul 2019

In this study several permeation enhancers are evaluated for their ability to permeate high molecular weight benzoylaconitine. The results showed that Plurol® Oleique CC 497 enabled the highest permeation. FT-IR studies demonstrated that the enhancer had strong interactions with the Stratum corneum, both in the hydrophilic and lipophilic regions. The optimized patch formulation showed excellent analgesic and antiinflammatory effect.

A Proof of Concept for 3D Printing of Solid Lipid-Based Formulations of Poorly Water-Soluble Drugs to Control Formulation Dispersion Kinetics

  • Scientific publication

Pharmaceutical Research volume 36, Article number: 102 doi: 10.1007/s11095-019-2639-y. - May 2019

Vithani K, Goyanes A, Jannin V, Basit AW, Gaisford S, Boyd BJ

In this study, the authors show that solid SMEDDS can be produced with a 3D printing  process and solid and semi-solid lipid excipients. The proof of concept is established with cinnarizine and fenofibrate as model drugs.

Colloidal aspects of dispersion and digestion of self-dispersing lipid-based formulations for poorly water-soluble drugs

  • Scientific publication

Advanced Drug Delivery Reviews, Volume 142, Pages 16-34 https://doi.org/10.1016/j.addr.2019.01.008 - May 2019

Kapilkumar Vithani, Vincent Jannin, Colin W. Pouton, Ben J. Boyd

In this review article, the authors explain the importance of the colloidal structures formed during dispersion and digestion of self emulsifying lipid-based formulations on drug solubilization and absorption.

A review of the techniques used to characterize the colloidal structures is also carried out.

High shear blending with glyceryl distearate provides individually coated drug particles for effective taste masking

  • Scientific publication

In this study the authors used:
– A design of experiment, to evaluate the effect of process parameters (blending speed, chopper speed and coating time) on drug particle size.
– Potassium chloride as model drug.

The study showed:
– Individual particle coating was achieved at 450 rpm with 20% glyceryl distearate (Precirol® ATO 5) at 48°C
– High shear coating is as efficient as fluid bed coating for taste masking
– A trained sensory panel confirmed the effectiveness of the process on taste masking
