摘要
Low bioavailability of rifampicin, one of the main antituberculous agents, stimulates searches of its new optimized formulations. The present study has shown a possibility of rifampicin incorporation into nanoparticles from plant phosphatidylcholine (diameter of 20-30 nm). Addition of sodium oleate to the phospholipid system caused a 2-fold increase in the percent of rifampicin incorporation. The maximal concentration of rifampicin assayed in plasma samples by LC/MS was observed 1 h after oral administration to rats (6 mg/kg) and represented 0.5 and 4.2 μg/mL for free rifampicin and rifampicin incorporated in the phospholipids-oleate nanoparticles, respectively. These levels were maintained for more than 2 h of the experiment. High rifampicin bioavailability in the oleate containing phospholipid nanosystem suggests its prospects for practical use. © Pleiades Publishing, Ltd., 2014.
