Bioanalytical part is the most important step in clinical pharmacokinetic studies. Employed bioanalytical methodology is one of the key success factors for the studies concerned.

Measurement of concentrations of drug substances in biological media can be performed during the following types of studies:

  • bioequivalence studies;
  • phase I pharmacokinetic studies;
  • additional pharmacokinetic part in phase II-IV studies.

The bioequivalence studies and phase I studies are primary scope of work performed by the bioanalytical laboratory Quinta-Analytica Yaroslavl. Nevertheless, considering the versatility of methodological approaches applied in different types of pharmacokinetic studies, the laboratory is ready for cooperation in the field of other aspects of research work.

The services of Quinta-Analytica Yaroslavl LLC performed within the scope of bioanalytical part of pharmacokinetic studies include the following:
