Pharmacokinetic (PK) and Toxicokinetic (TK) Bioanalysis
Pharmacokinetic (PK) and Toxicokinetic (TK) bioanalysis is a critical aspect of drug development. These studies may be exploratory in nature or more extensive and formal. Understanding the bioavailability, exposure, half-life, clearance and metabolism of a drug may be the difference between success and failure in the clinic.
PK/PD Bioanalysis at Pacific BioLabs
Pacific BioLabs’ analytical and bioanalytical laboratory contains GLP-compliant systems and qualified instrumentation, including multiple LC/MS/MS systems as well as ELISA platforms to provide sensitive, high throughput evaluation of drug concentration in a variety of matrices. Stability studies and metabolite identification can be conducted to understand the strengths and liabilities of your compound.
PBL can quickly perform bioanalytical method development and validation of sensitive, accurate and robust PK assays in a number of different matrices from different species. PBL’s chemists have experience working with plasma, serum, urine, CSF, and tissue, and will optimize the extraction conditions to provide a reproducible and robust method.
Additionally, PBL provides in vivo dosing and sampling in multiple species, and can coordinate PK studies to perform all aspects including in vivo dosing and sample collection, bioanalysis, and preparation of PK data using WinNonlin.
Pharmacokinetic Studies Utilizing ICP-MS
For compounds containing metals, ICP-MS may be used to perform PK bioanalysis. ICP-MS has the benefits of low detection levels (as low as 1ppb) and good specificity. Many classes of drugs contain metals – copper, iron, platinum, gold, and cobalt are just of few examples of the many metals that can be integrated into drug molecules. PK by ICP-MS may be an excellent choice to analyze these types of compounds.
