PK by ICP-MS may be an excellent choice to analyze these types of compounds. WinNonlin from Certara is the most widely used softare for PK/PD analysis. 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. ICP-MS has the benefits of low detection levels (as low as 1ppb) and high specificity. Pharmacokinetic Studies Utilizing ICP-MSįor compounds containing metals, ICP-MS may be used to perform PK bioanalysis. PBL has supported bioanalysis for many clients from exploratory research, preclinical studies to Phase I through Phase IV clinical trials.Īdditionally, PBL provides in vivo dosing and sampling in multiple animal species, and can coordinate PK studies to perform all aspects including in vivo dosing and sample collection in animals, bioanalysis, and preparation of PK data using WinNonlin. PBL’s chemists have experience working with plasma, serum, urine, CSF, and tissues, and they will optimize the extraction conditions to provide a reproducible and robust method. PBL can quickly perform bioanalytical method development and validation of sensitive, accurate and robust PK assays in a number of biological matrices. Over 6,000 researchers at 1,500 global biopharmaceutical companies, academic institutes and regulatory agencies rely on WinNonlin for their biosimulation studies.
WINNONLIN OPTIMIZER SOFTWARE
The IVIVC Toolkit is a software tool that creates and substantiates the Level A correlation outlined in the FDA guidance to correlate the in vitro dissolution proÞle of a dosage form with the in vivo pharmacokinetic (PK) proÞle. Phoenix® WinNonlin ® is the trusted industry standard biosimulation software tool for pharmacokinetic and pharmacodynamic (PK/PD) modeling, non-compartmental and compartmental analysis. Pacific BioLabs’ analytical and bioanalytical laboratory contains GLP-compliant systems and qualified instrumentation, including multiple LC/MS/MS systems as well as ELISA and MSD platforms to provide sensitive, high throughput evaluation of drug concentration in a variety of biological matrices. WinNonlin ¨ on a daily basis to support formulation optimization. Understanding the bioavailability, exposure, half-life, clearance and metabolism of a drug may be the difference between success and failure in the clinic. These studies may be exploratory in nature or more extensive and formal. Pharmacokinetic (PK) and Toxicokinetic (TK) bioanalysis is a critical aspect of drug development. bioanalysis, and preparation of PK data using WinNonlin. The goal of animal model studies is to mimic the infectious diseases seen in humans to allow for robust PK/PD studies to find the optimal drug exposures that lead to therapeutic success.Pharmacokinetic (PK) and Toxicokinetic (TK) Bioanalysis serum, urine, CSF, and tissues, and they will optimize the extraction conditions to provide. The rationale for PK/PD-modelling is to link pharmacokinetics and pharmacodynamics in order to establish and evaluate dose-concentration-response relationships and subsequently describe and predict the effect-time courses resulting from a drug dose.Īnimal infection models in the pharmacokinetic/pharmacodynamic (PK/PD) evaluation of antimicrobial therapy serve an important role in preclinical assessments of new antibiotics, dosing optimization for those that are clinically approved, and setting or confirming susceptibility breakpoints.

The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. Pharmacokinetics describes the drug concentration-time courses in body fluids resulting from the administration of a certain drug dose, pharmacodynamics the observed effect resulting from a certain drug concentration. The IVIVC Toolkit is an optional add-on to WinNonlin that extends its capabilities beyond pharmacokinetic, pharmacodynamic, and non-compartmental analysis to the development and application of in vivo-in vitro correlations. Pharmacokinetics (from Ancient Greek pharmakon 'drug' and kinetikos 'moving, putting in motion' see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to determine the fate of substances administered to a living organism. Pharmacokinetic (PK) and pharmacodynamic (PD) information from the scientific basis of modern pharmacotherapy.
