Pharmacokinetics (PK) is the analysis and description of the disposition of a drug in the body. PK includes development of the mathematical description of all dispositional processes in the body, defined as ADME – absorption, distribution, metabolism, and elimination. PD describes what the drug does to the body, whereas PK describes what the body does to the drug.
Pk definition: Pharmacokinetics (PK) is defined as the analysis and description of the disposition of a drug in the body, encompassing development of the mathematical description of all dispositional processes in the body. Closely-related fields include clinical pharmacokinetics, pharmacodynamics, pharmacology and toxicokinetics. The PK sciences are intrinsic to all aspects of pharmaceutical therapy: development and registration; optimization of therapy; study design; therapeutic drug monitoring.
Pharmacokinetics is the study of the movement of drugs through the body, including their absorption, distribution, metabolism and excretion. These processes will influence how quickly the body is exposed to a drug and how long the effects of that drug last. Pharmacokinetics is an important aspect of patient safety because it helps doctors understand how their patients will respond to different doses of a drug. Pharmacokinetics are also important for physicians because they may allow them to choose alternative medications for use in people who cannot tolerate certain drugs due to their pharmacokinetic properties.
Preclinical research services involve multiple studies critical to assess drug efficacy and safety in animal models, complete Investigational New Drug (IND) filing studies, and apply for regulatory approvals such as Investigational New Drug applications. Successful completion of the drug IND package is the first milestone towards clinical development. Many drugs are rejected during preclinical stage due to subpar treatment effects or adverse outcomes including toxicity. Hence it is imperative to look for a preclinical CRO with competent personnel who have relevant scientific expertise and regulatory awareness. Preclinical CRO is the first step in drug development. Preclinical studies involve animal testing and advancing a drug candidate into the clinical phase. If these studies are not appropriately designed, your medication can be dismissed by the regulatory authorities in error. Hence, it is imperative to look for a preclinical CRO with competent personnel who have relevant scientific expertise as well as regulatory awareness.
Preclinical research services are critical studies to ensure drug efficacy, safety and dosing in animals. If the studies are not adequately designed or the personnel with expertise on animal models or regulatory awareness are not available, your drug can be dismissed prematurely by the regulatory authorities in error. Hence, it is critical to seek out a preclinical CRO with competent personnel who have relevant scientific expertise as well as regulatory awareness.
Drug research is a complex and meticulous process. There are many unique challenges that must be handled with the utmost accuracy, care, and prudence. If you want to move your drug candidate from preclinical to clinical trials, it’s essential to partner with a CRO that has expertise in handling drug development programming. Preclinical CRO services are offered by Biomarker Labs to ensure that your researchers are proceeding according to plan.
