PHARMACOKINETIC STUDIES OF NEW SILVER-BASED COMPLEX

Objective: Investigation of pharmacokinetics parameters of the new silver-based compound of general formula C 6 H 19 Ag 2 N 4 LiO 6 S 2 , called “Argosil”, with high antiviral activity. Methods: Water solution of complex administered intragastrically in the dose rate of 100 mg/kg body weight of mice BALB/c (males) aged 1.5-2.0 mo. Blood and tissues samples analyzed by mass spectrometry. Results: Half-life of the drug was about 4 h at the initial stage. About 5% of the initially introduced silver detected after 24 h. Maximum drug concentration observed in the lung tissues. Conclusion: Results make the basis for further test and clinical implementation. Taken into account low toxicity and antiviral properties of this compound, it looks especially effective for lung infections treatment.
