At BOC Sciences, we perform dissolution testing to evaluate drug release rates in various media. This testing is applied to tablets, capsules, and modified or extended-release formulations, providing detailed comparative insights into formulation performance and in vitro release behavior for preclinical bioequivalence evaluation.

We establish in vitro-in vivo correlation models by linking dissolution data with animal pharmacokinetic profiles. This approach predicts in vivo absorption behavior, evaluates formulation performance, and supports preclinical bioequivalence assessment by providing a quantitative understanding of drug release and systemic exposure relationships.

Our permeation and diffusion testing services evaluate drug absorption from topical and transdermal formulations. Using skin diffusion cells or simulated skin models, we measure drug permeation rates, providing detailed data on formulation performance, tissue penetration, and absorption kinetics for preclinical bioequivalence and formulation optimization.

We conduct pharmacokinetic studies in preclinical models, including mice, rats, rabbits, and dogs. Blood samples are analyzed to determine absorption rates, Cmax, AUC, half-life, and other key PK parameters, enabling detailed assessment of systemic exposure and comparative evaluation between test and reference formulations in preclinical bioequivalence studies.

For modified or extended-release formulations, we perform multi-timepoint blood sampling to generate detailed pharmacokinetic profiles. This approach enables precise characterization of concentration–time curves, evaluates absorption dynamics, and provides comprehensive data for comparative preclinical bioequivalence and formulation performance assessment.

We conduct tissue distribution studies for topical and transdermal formulations by analyzing drug concentrations in target tissues and organs. This testing provides detailed insights into drug absorption, local exposure, and distribution characteristics, supporting comprehensive preclinical bioequivalence evaluation and formulation development strategies.

Bioequivalence studies are designed to evaluate whether two drug formulations exhibit similar absorption rates and extents in the body. By comparing pharmacokinetic parameters between a reference drug and a generic or alternative formulation, these studies help determine if the two products can be considered equivalent in vivo. Such studies provide critical insights for formulation development and optimization. BOC Sciences offers expertise in designing and executing BE study protocols, providing tailored experimental design and data analysis support.
Bioavailability studies primarily measure how much and how quickly a drug is absorbed into the bloodstream from a single formulation. Bioequivalence studies, on the other hand, compare the absorption profiles of two formulations to confirm whether they are essentially equivalent. In short, BA studies assess “how efficiently a drug enters the bloodstream,” while BE studies verify “whether two formulations perform similarly in vivo.” Understanding this distinction is critical for rational drug development and formulation strategy.
BE (Bioequivalence) and BA (Bioavailability) studies are both essential tools for evaluating drug behavior in vivo. BA studies provide quantitative information on drug absorption from a single formulation, while BE studies compare absorption between different formulations to determine interchangeability. Well-designed BE/BA studies reduce development risks and provide actionable data for formulation improvement. BOC Sciences has mature processes for BE/BA studies and can provide professional solutions tailored to the properties of your drug.
The primary objective of a bioequivalence study is to confirm that two drug formulations have comparable absorption profiles in the body, ensuring that a substitute product delivers predictable efficacy. By precisely measuring pharmacokinetic parameters such as Cmax and AUC, companies can make informed decisions in formulation development and optimization, directly enhancing product competitiveness.
BE studies provide critical scientific data to guide formulation design and the development of alternative drug products. For companies aiming to optimize product lines or accelerate market entry, these studies help reduce development risks while enhancing product reliability and competitiveness.
