Non Compartmental Analysis Pharmacokinetics Testing
The non-compartmental analysis (NCA) method in pharmacokinetics is a fundamental approach used to analyze drug concentration-time profiles, which are critical for understanding how a drug behaves within the human body. This method provides key insights into bioavailability and bioequivalence by quantifying parameters such as area under the curve (AUC), maximum plasma concentration (Cmax), time to reach Cmax (tmax), half-life (t1/2), and total systemic clearance (CL/F).
At our laboratory, we offer comprehensive non-compartmental analysis services tailored to meet the stringent requirements of pharmaceutical testing. Our expertise lies in providing accurate, reliable, and compliant data that support the development, approval, and monitoring of new drug formulations. NCA is particularly useful for early-stage drug candidates where rapid turnaround times are essential.
The process begins with sample collection, which involves obtaining blood or plasma samples from subjects at specified intervals after administration of the test substance. Proper specimen handling is critical to ensure accurate results. Our laboratory adheres strictly to Good Laboratory Practices (GLP) and International Conference on Harmonisation (ICH) guidelines, ensuring that all procedures are validated and reproducible.
After collection, the samples undergo rigorous pre-processing steps, including centrifugation and storage in appropriate conditions to prevent degradation or contamination. We then employ advanced analytical techniques such as liquid chromatography-mass spectrometry (LC-MS/MS) for precise quantification of drug concentrations. This ensures that we obtain robust data points necessary for reliable NCA.
The NCA analysis itself involves statistical calculations based on the collected concentration-time profiles. Software tools like WinNonlin or Phoenix are used to perform these analyses, which help in deriving important pharmacokinetic parameters. These parameters provide detailed information about drug absorption, distribution, metabolism, and excretion, thereby aiding in optimizing therapeutic efficacy and safety.
Our laboratory offers additional services that complement NCA testing, including population pharmacokinetics (PPK) analysis and bioequivalence studies. This holistic approach allows us to offer a comprehensive suite of services that cater to various stages of drug development, from preclinical research to post-market surveillance.
