Title: Structure - Function Relationship of Lipid-Based Excipients in Advanced Pharmaceutical
Sharareh
Salar-Behzadi is assoc. professor at the department of pharmaceutical
technology and biopharmacy, University of Graz, and key researcher at Research
Center Pharmaceutical Engineering GmbH, Graz, Austria. She studied pharmacy and
received her PhD from University of Vienna in pharmaceutical formulation and
process development.
Her interest is
in pharmaceutical material science, solid state, structure-function analysis of
pharmaceutical excipients, with a focus on lipid-based drug delivery systems,
particle engineering for different routes of administration and patient-centric
product development.
The following three factors play an important role on the gradually
increased expenses of global pharmaceutical R&D: a) rising number of new FDA
approvals in the recent years, b) increased awareness of pharmaceutical
companies of the sustainability of their production, c) increased awareness of
the specific requirements of patients as individuals. These trends are closely
associated with the demand for innovative and robust dosage forms with stable
performance. Using excipients with desired functionality is the key parameter for
realizing this demand. In this context, lipid-based excipients (LBEs) have been
increasingly applied due to their advantages such as being naturally occurring
materials, low-toxic, biocompatible, and easily available. The serious
challenge, however, is their unstable solid state, which affects the stability
and robustness of pharmaceutical products.
In this work, the structure-function relationship of LBEs and its
effect on the performance of pharmaceutical products are discussed. Moreover,
the ideal properties of LBE are defined from molecular to macroscopic level,
taking a group of advanced LBEs as an example. Case-studies are shown to
discuss their functionality as matrix agents and solubility enhancer in preparation
of stable nano-lipid suspensions, spray-dried engineered particles, lipid-based
extruded filaments and 3D-printed forms for a variety of pharmaceutical dosage
forms.
