Adeola is a Lecturer in the Department of Pharmacy. She graduated from the University of Ibadan, Ibadan, Nigeria with a degree in Pharmacy and then obtained a Master’s degree in Pharmaceutical Science at Aston University, Birmingham, UK. She was awarded a PhD in 2014 by the University of Huddersfield. Her PhD thesis was titled, “Design of gastro-retentive systems for the eradication of helicobacter-pylori infections in the treatment of peptic ulcer” and was supervised by Professor Barbara Conway. Adeola worked on various research projects and teaching upon completion of her PhD in the Department of Pharmacy prior to her appointment by the University of Huddersfield as a Post-doctoral Research Assistant in May 2015, then Research Fellow in August 2016. She is a Fellow of the Higher Education Academy.
Adeola’s research interests are primarily in the area of targeted drug delivery with emphasis on mucoadhesive and gastroretentive drug delivery systems in the form of surface-modified or conjugated microparticles and nanoparticles to enhance the gastro-retention of delivery systems. In addition, recent research focuses on modification of natural or synthetic polymers to enhance their mucoadhesive and physicochemical properties. Other areas of interest include particle engineering of poorly soluble drugs to enhance their solubility and stability profiles, design of in vitro drug diffusion models and assessing the pharmaceutical applications of natural polymers.

Drug delivery systems directly targeted to the organs or absorption membrane for local or systemic delivery enhances the therapeutic efficacy of the delivered drug. One of the strategies used in drug targeting is mucoadhesive drug delivery. Mucosal layers are found in various regions of the body including the eyes, respiratory tract, gastrointestinal tract and the reproductive tract. These mucoadhesive devices adhere to mucosal layers maintaining an intimate contact with the surface while delivering its drug contents in a controlled manner for local effect or for transmucosal absorption. This direct delivery offers several advantages such as the ability to directly target local disorders such as infections, thereby enhancing the therapeutic effect, reduction of accumulation of drugs in areas where they are not required and minimising side effects. Current research have been focused on the use of mucoadhesive polymers, which have weak and non–specific interactions with mucosal layers, and in most cases such interactions are inadequate for localization of a drug delivery device to a target mucosal site. Therefore, there is increasing interest in the development of mucoadhesive polymers, which have stronger and more specific (site-specific) interactions with mucosal target sites. The aim of this research is to develop novel mucoadhesive polymers that can be used in the design of targeted buccal, nasal and gastroretentive drug delivery systems for treatment of disorders such as oropharyngeal candidiasis, allergic rhinitis and Helicobacter-pylori infection.
Keywords: Mucoadhesive polymers, site-specific delivery, buccal delivery, nasal delivery, mucus model
Natural materials are playing an increasing role as alternatives to synthetic pharmaceutical excipients. This is due to their biocompatibility, low cost, and relative abundance. These natural polymers are now being widely used in the pharmaceutical industry as polymers in various drug delivery systems. Examples of such polymers include sodium alginate, guar gum, chitosan, gum karaya etc. This project involves the extraction of gums and mucilages from different parts of suitable plant materials and the characterization of the extract. In addition, these polymers will be assessed against commercially available polymers in their native form or with some modification to tailor their use for various pharmaceutical applications.
Keywords: Natural polymers, synthetic polymers, gums, plants, polysaccharides
The use of drug delivery technologies that improve drug pharmacokinetics and facilitate local drug delivery to target tissues can enhance the efficacy of various drug therapies. Drug delivery to target mucosal surfaces such as those of the lungs, GI tract, nose, eye etc. is of great interest however, the viscous, elastic and the sticky nature of mucus present in these target sites make drug delivery challenging as the mucus could trap and clear foreign particles such as conventional drug and gene nanocarriers from these surfaces. Mucus-penetrating particles (MPP) avoids rapid mucus clearance and/or reach the underlying epithelia where the drug is required or absorbed. MPP offer advantages of sustained drug delivery at the mucosal surfaces therefore providing improved efficacy and reduced therapeutic side effects. This is achieved by several methods such as modification of particle surface with polymers such as Pluronic F-127 or by disrupting the mucus barrier with chemicals such as N-acetyl-l-cysteine (NAC). This research aims to develop muco-penetrating particles to enhance delivery of drugs and macromolecules to the GI tract.
