Abstract
To study features of pharmacokinetics of ofloxacin as a part of anion PEGylated niosomes on a basis of sorbitan monostearate (Span 60) to experimental white mice per os. Ofloxacin was entrapped in niosomes consisting of Span 60, cholesterol, PEG 4000 and dicetylphosphate. Sizes of niosomes estimated by means of probe microscopy. Efficiency of inclusion of an antibiotic in niosomes defined after removal of free drug by a centrifugation. The analysis of the quantitative contents of ofloxacin in samples carried out a method of a high performance liquid chromatography. We studied the main pharmacokinetic parameters of ofloxacin when used free and niosomal forms of antibiotic to experimental white mice per os. It is shown that use of oral niosomal forms leads to decrease of maximal concentration in serum and increase of ofloxacin half-life by 7,4 times in average compared to the free form. It is determined that bioavailability of ofloxacin in the niosomal form is 154% relative to the free form of the antibiotic. Niosomal microcontainers are perspective technology of encapsulation and the directe transport of antibacterial preparations through biological barriers. Using of niosomal formulation of ofloxacin is able to afford to increase considerably efficiency of treatment in comparison with a free form and significantly decrease negative effects of antibiotic therapy.
