Abstract
An important stage in the preclinical study of a new drug is the study of its pharmacokinetics: absorption, distribution, metabolism, and excretion of the drug compound.
The purpose of this study was to study the pharmacokinetics in healthy animals of a new analgesic based on hexaazaisowurtzitane (thiowurtzine).
Materials and methods. A technique for determining the concentration of thiowurtzine in the blood plasma and rat excreta has been developed and validated. Using high-performance liquid chromatography and tandem mass spectrometry, concentrations of thiowurtzine in plasma and rat excreta were determined after a single intragastric dose of 100 mg/kg.
Results. The peak concentration of thiowurtzine in the blood plasma of rats accounts for 2 hours, which is consistent with the pharmacodynamic data of the analgesic, the average retention time of the substance in the body reached 17.15 h after administration. Thiowurtzine is believed to be actively metabolized.
