Popis: Pharmacokinetics of compound M-11 (main metabolite of afobazole) after administration via different routes was studied in rats. After oral and intravenous administration, M-11 exhibited weakly pronounced bioconversion with the formation of a few metabolites that could be detected in plasma samples for about 3 hours. The absolute bioavailability of M-11 after oral administration was 68.3%. It was found that M-11 was completely absorbed from gastrointestinal tract of rats and characterized by "the first pass effect", after which approximately 70% of administered dose entered the circulation. The parent substance was determined neither in urine nor in feces.
