Clinical Pharmacokinetics

The aim of the Clinical Pharmacokinetics Research Group is to determine and use pharmacokinetic parameters to optimise dosing, pharmacodynamic response, and ultimately patient outcomes in specific patient subgroups. Research is multidisciplinary involving medical, nursing, clinical pharmacy and analytical expertise. Research interests include:

  • Assessing the effect of renal replacement therapies on the pharmacokinetics of commonly used antimicrobials in the intensive care setting
  • Exploring the impact of patient and clinical characteristics on distribution and clearance of antimicrobials
  • Dose optimisation through pharmacokinetics of antimicrobials, patient characteristics and clinical response.

Research is currently focussed on two clinical areas - ICU (critical illness) and Haematology.

Current Research Projects & Funding

Clinical Pharmacokinetics Research group- ICU

Academic PI Dr Deirdre D’Arcy. Collaborating academic researcher: Prof. Owen Corrigan and Clinical PI Tallaght University Hospital Dr. Maria Donnelly

Determination of Pharmacokinetic Parameters of commonly used drugs, such as Amphotericin B in critically ill patients. Research emphasis to date has been on the effect of continual renal replacement therapies on pharmacokinetics of antimicrobials. Amphotericin B research component was part-funded by (formerly) Cephalon Ireland Ltd. through the Intensive Care Unit, Tallaght University Hospital.

Clinical Pharmacokinetics Research group- Haematology

Academic PIs Dr Deirdre D’Arcy, Sheila Ryder. Clinical PI Tallaght University Hospital: Dr. Johnny McHugh

An investigation to determine an appropriate teicoplanin dosage regimen for the treatment of Gram-positive infection in patients with haematological malignancy. Funded by the Meath Foundation through Tallaght Hospital. Commenced 2012.
This project is a collaborative project between the Clinical Pharmacokinetics Research Group and the Pharmacy Practice Research Group
