Dr. Deirdre D'Arcy

Associate Professor (Pharmacy)
25/6/7 WESTLAND ROW


Deirdre D'Arcy (M Pharm, PhD, MPSI); Deirdre is a qualified pharmacist (1999) and holds post graduate diplomas in both Clinical Pharmacy and Quality Improvement, and a PhD in Pharmaceutical Technology. She is a registered pharmacist with the Pharmaceutical Society of Ireland and the General Pharmaceutical Council (UK). After spending 3 years training as a specialist clinical pharmacist, during which time she developed an interest in Clinical Pharmacokinetics, Deirdre spent some time in community pharmacy. Following this she undertook a PhD in Pharmaceutical Technology, exploring methods to mathematically simulate pharmaceutical processes. Concurrently, she undertook a diploma in quality improvement and also worked part-time as a community pharmacist. She embarked on her academic career in 2005, in the School of Pharmacy and Pharmaceutical Sciences (SOPPS) TCD. This unique combination and breadth of experiences, and her professional status as a qualified, registered pharmacist, has equipped Deirdre with a distinctly valuable perspective on the interplay between clinical aspects of pharmacy practice and the use of pharmaceutical technology in medicines development. This extensive background has facilitated a range of teaching roles, didactic and experiential, at undergraduate and postgraduate level. Furthermore, it has enabled her to develop and lead the novel role of Integration Co-ordinator for the new Pharmacy (Integrated) Programme, promoting integrative teaching and learning between core science, clinical, and experiential learning; and the embedding of graduate attributes and competences within the curriculum. Context for Integration Co-ordinator role: The new Pharmacy (Integrated) Programme (first intake 2015) results from a change in the national pharmacy education requirements of the Pharmaceutical Society of Ireland. A minimum of 12 months experiential placement-based learning, which used to take place post-graduation and before pharmacist registration, is now integrated within the core 5-year academic programme. Thus the new Pharmacy (Integrated) programme represents a mammoth shift in educational delivery by the SOPPS, with significantly different, advanced programme learning outcomes. Formal, structured integration of campus-based and experiential placement-based learning was thus novel to SOPPS pharmacy education. Furthermore, modern pedagogical perspectives on education in all health care settings have a focus on the integration of core science learning with more applied therapeutics/clinical learning content. Deirdre has been involved in 3 International EU-funded educational projects (Institutional lead on one of these), prompting innovations in Technology Enhanced Learning and assessment methodologies. These roles and innovations are fully aligned with the recommendations of the Trinity Education Project. Deirdre is also an active researcher, again supported by her unique combined experience of Patient-Facing practice and Pharmaceutical Technology. Current research includes 2 main strands: 1: Application of computational modelling and simulation techniques in pharmacy and pharmaceutical technology to improve processes and practice, including pharmacokinetic and dissolution modelling 2: Clinically relevant drug development and delivery to special populations. She was an academic PI on several clinical PK research projects in collaboration with associated teaching hospital She is involved in several international collaborations, with relevance to access to medicines and personalised medicines. Research outputs have resulted in peer reviewed publications, invited presentations at national and international level, partaking in national policy submission groups, and tangible outputs in the form of changes to medicines dosing policy and software development. Research funding sources include IRCSET, the Meath Foundation, Pharmaceutical Industry.

My research interests can be presented as 2 main themes: 1. Application of computational modelling and simulation techniques in pharmacy and pharmaceutical technology, to improve processes and practice. I have used a number of different computational modelling and simulation approaches and packages in 2 main contexts: A) Clinical Pharmacokinetics: Clinical pharmacokinetics (PK) involves modelling the time course of a medicine in the body, in order to understand the medicine's journey through the body. This then facilitates design of optimal dosing regimens (dose and interval) to achieve therapeutic goals. My clinical PK work to date has focussed on optimising antibiotic use. I am the academic PI for the Clinical Pharmacokinetics Research Group, a collaboration with Tallaght Hospital. I have worked with both the Intensive Care Unit and Haematology Departments, and the hospital Pharmacy Department. B) Pharmaceutical Drug Development: My modelling and simulation in Pharmaceutical Drug Development has focussed on dissolution modelling. Dissolution testing involves determination of the rate and extent of drug dissolution and release from any dosage form. It is an essential component of early stage drug formulation development, and also quality control (QC). Of global research interest are i) the development of dissolution testing methodologies which best reflect the in vivo environment for drug release, to support early stage formulation development, and ii) understanding sources of variability in dissolution testing to minimise risk of failure to meet specifications in QC testing of manufactured batches. I have developed significant expertise in computational fluid dynamics (CFD) modelling of fluid dynamics within different dissolution test apparatuses, assisting determination of sources of variability from a QC perspective and also in vivo relevant dissolution method development. Furthermore, I have co-developed a dissolution simulation package with Dr. Tim Persoons (Dept. of Mechanical and Manufacturing Engineering, TCD). We have accompanied this simulation package with a novel investigational tool for visualisation of dissolution, based on the principles of shadowgraph imaging. 2. Clinically relevant drug development and delivery to special populations. The dual concepts of access to medicines and personalised medicines are highly relevant in today's global pharmaceutical environment. Based on a combination of my clinical and pharmaceutical technology experience and expertise, my research addresses both of these concepts.Relevant international collaborations include those with Cambridge University and University of Bath, UK, exploring the development of dissolution and drug release testing methodologies which will support drug development for two specific populations: critically ill patients and neonates/infants. My collaboration with Cambridge University focussed on the development of a dissolution testing environment from a nipple shield designed specifically with the aim of drug delivery to neonates while breastfeeding. My collaboration with University of Bath focusses on the development of dissolution testing for lipid-based parenteral formulations, with the dissolution medium representing the characteristics of plasma in critically ill patients. Of topical significance is my collaboration with the National Centre for Pharmacoeconomics and the School of Medicine, TCD, investigating the role of pharmacokinetic "boosting" drugs in reducing dosing (cost) of expensive medicines. Finally I have had an intereset in investigating the potential for provision of breastfeeding support in a community pharmacy environment. Primarily this focusses on support for medication use (in either baby or mother) during breastfeeding, but with a general health promotion angle also.
