Abstract

Formulation of poorly water-soluble and lipophilic drugs in lipid-based delivery system is recognised as a potential strategy for improving their oral absorption. With only 2–4% oral lipid-based formulations available in the pharmaceutical market worldwide, the development of lipid-based products is clearly behind the rate of discovery of new chemical entities exhibiting poor aqueous solubility. A novel silica-lipid hybrid (SLH) microcapsule system for enhancing the oral absorption of low solubility and high permeability (BCS Class II) drugs has been developed and demonstrated for the model drug celecoxib (CEL). This thesis describes (i) the fabrication of the SLH microcapsule system, (ii) the systematic in vitro characterisation of its dissolution and lipolysis properties and (iii) the in vivo pharmacokinetic investigation of various CEL formulations in a rat model.
