Raj Badhan joined Aston University in June 2010 as Lecturer in Pharmacokinetics following over 3 years of extensive pharmacokinetics training with the world-renowned Centre for Applied Pharmacokinetics Research as a post-doctorate research associate, within the School of Pharmacy at the University of Manchester.

Raj has a broad background and interest in applying the principles of clinical pharmacokinetics to challenging pre-clinical and clinical scenarios in the context of medicines optimisation. As a pharmacokineticist and practicing pharmacist, he has a singular vision of developing tools and approaches which provide clear end-user/clinical benefits. This approach has driven successes in developing research tools to predict oral drug absorption and central nervous system drug biodistribution in addition to medicines optimisation for a range of disease conditions (e.g. tropical disease, cardiovascular disease, drug abuse).

Improving the use of methadone for drug users with tuberculosis to prevent withdrawal

Medical Xpress  online


Dr. Raj K. Singh Badhan, Lecturer in Pharmacokinetics, Aston University said: "We found that rifampicin significantly alters the level of methadone in the blood and necessitates dose adjustments, with daily doses of almost double those commonly used in clinical practice required for optimal levels of methadone in the blood.

Drug dosing during pregnancy—opportunities for physiologically based pharmacokinetic models

Journal of Pharmacokinetics and Pharmacodynamics

2020 Drugs can have harmful effects on the embryo or the fetus at any point during pregnancy. Not all the damaging effects of intrauterine exposure to drugs are obvious at birth, some may only manifest later in life. Thus, drugs should be prescribed in pregnancy only if the expected benefit to the mother is thought to be greater than the risk to the fetus. Dosing of drugs during pregnancy is often empirically determined and based upon evidence from studies of non-pregnant subjects, which may lead to suboptimal dosing, particularly during the third trimester.

Quetiapine dose optimisation during gestation: a pharmacokinetic modelling study

Journal of Pharmacy and Pharmacology

2020 The second‐generation antipsychotic quetiapine has been demonstrated to undergo gestation‐related changes in pharmacokinetics. This study applied pharmacokinetic modelling principles to investigate the mechanism of these changes and to propose new dosing strategies to counteract these changes.

Precision dosing‐based optimisation of paroxetine during pregnancy for poor and ultrarapid CYP2D6 metabolisers: a virtual clinical trial pharmacokinetics study

Journal of Pharmacy and Pharmacology

2020 Paroxetine has been demonstrated to undergo gestation‐related reductions in plasma concentrations, to an extent which is dictated by the polymorphic state of CYP 2D6. However, knowledge of appropriate dose titrations is lacking.

A dynamic perfusion based blood-brain barrier model for cytotoxicity testing and drug permeation

Scientific Reports

2020 The blood-brain barrier (BBB) serves to protect and regulate the CNS microenvironment. The development of an in-vitro mimic of the BBB requires recapitulating the correct phenotype of the in-vivo BBB, particularly for drug permeation studies. However the majority of widely used BBB models demonstrate low transendothelial electrical resistance (TEER) and poor BBB phenotype.

Intracellular uptake of EGCG-loaded deformable controlled release liposomes for skin cancer

Journal of Liposome Research

2019 Caucasian population groups have a higher propensity to develop skin cancer, and associated clinical interventions often present substantial financial burden on healthcare services. Conventional treatments are often not suitable for all patient groups as a result of poor efficacy and toxicity profiles. The primary objective of this study was to develop a deformable liposomal formulation, the properties of which being dictated by the surfactant Tween 20, for the dermal cellular delivery of epigallocatechin gallatein (EGCG), a compound possessing antineoplastic properties.
