The pharmacokinetics of dihydroquercetin (DHQ) in the forms of parent substance and a new liposomal formulation (Flamena D) have been studied in rats upon single peroral administration in a dose of 50 mg/kg. DHQ concentration after enzymatic hydrolysis in the blood plasma was determined by HPLC with UV detection. The elimination half-life of DHQ introduced in the form of Flamena D was about T(1/2) = 1.3 h. The relative bioavailability of DHQ after the administration of Flamena D amounted to 159% in comparison to that of the parent substance of DHQ.
