About the Project
This project aims to develop novel carrier particles capable of protecting biologics from acid and enzymatic degradation and improving the absorption by increasing the contact time with the absorptive epithelium. The developed particles must be able to satisfy the required enteric and mucoadhesive properties to achieve above stated goals. This study will include the development of composite particles using layered silicates such as natural or synthetic smectites and natural polymers such as alginate, gelatine, dextrin and glucomannan to obtain particles with required properties. The active will be encapsulated during or after the formulation of these particles and their suitability as potential oral delivery carriers will be examined. Furthermore, incorporation of mucolytic agents and/or cell penetration enhancer will also be studied to potentially improve the absorption of biologics through GI tract.
This project will involve formulation and physicochemical characterisation of developed carrier systems. The formulation of micro or nanoparticles will be based on our previous experience with similar systems where interaction between layered silicates and polymers at favourable conditions (pH, ionic strength and ratio) followed by crosslinking of the polymer results in highly stable and porous structures capable of adsorbing or encapsulating biologics within them. The developed particles will be evaluated via various analytical techniques including DSC, ATR-FTIR, SEM/TEM, BET and texture analysis. The efficacy of these particles as carrier systems will be evaluated by establishing drug encapsulation/adsorption capabilities and mucoadhesive properties. The stability of active will be evaluated after the incubation of active containing particle in various media emulating GI tract. The composite particles with most promising characteristics will then be used to develop the drug delivery system for the potential oral delivery of a pharmacologically active biologic.
This project will give applicant the opportunity to research into the highly important area of oral delivery of biologics and develop potentially clinically relevant drug-delivery technology capable of making oral administration of biologics a viable option by applying their knowledge of formulation and analytical science.
