Laboratory of Pharmacology and Toxicology

Research mission

The main research mission of the Laboratory of Pharmacology and Toxicology (Prof. dr. S. Croubels, Prof. dr. M. Devreese) consists of generating and communicating insights in in vivo ADME processes (absorption, distribution, metabolisation and excretion) and PK/PD modeling of human and veterinary drugs and toxins in a variety of animal species. The Laboratory is OECD GLP compliant for the conduct of in vivo ADME trials, pharmacokinetic modeling, safety studies, and bio-analysis of human and veterinary drugs. The Laboratory has over 20 years of experience in the development of analytical methodologies for the detection and quantification of xenobiotics (drugs, mycotoxins and their metabolites) in different biological samples such as plasma and tissues, using (UHP)LC-MS/MS and HR-LC-MS, and in pharmacokinetic (PK) and toxicokinetic (TK) modeling of these compounds.  The laboratory has 4 (UHP)LC-MS/MS instruments, 1 UHPLC-UV instrument and access to 3 HR-LC-MS instruments.

Doctoral research topics veterinary pharmacology

The research within the veterinary pharmacology group is related to optimization of antmicrobial dosage regimens for reduced resistance selection on the one hand, and the development of a juvenile piglet model as a pediatric preclinical model for PK/PD.

Doctoral research topics veterinary toxicology

The research within the veterinary toxicology group is related to the mycotoxin problem in livestock. More specifically, bioanalytical method development for quantification in animal matrices; the toxicity, toxicokinetics and residues of (emerging) mycotoxins in livestock; interactions between mycotoxins and pathogens in livestock and models for in vitro and in vivo safety and efficacy testing of mycotoxin detoxifiers. The laboratory is also a member of the interdisciplinary research association group MYTOX.
