    Abstract:
    BACKGROUND AND OBJECTIVE: Fufang Danshen formula, a famous Chinese patent medicine containing Salvia miltiorrhiza, Panax notoginseng and borneol, has been widely used in the treatment of coronary heart disease. The application is restricted by low bioavailability partly due to Panax notoginseng saponins (PNS) instability and low in vivo absorption. Thus, adhesive pellets were developed to improve bioavailability. The objectives of the present study were to evaluate the adhesive preparation by describing PNS's plasma pharmacokinetics in vivo and compare adhesive micro pills with normal preparation. METHOD: LC-MS/MS method was established to analyze five ingredients, notoginsenoside R1 (R1), ginsenoside Rg1 (Rg1), ginsenoside Rb1 (Rb1), ginsenoside Re (Re), and ginsenoside Rd (Rd), in rats' plasma to describe the pharmacokinetic parameters of PNS. RESULTS: The pharmacokinetic parameters were significantly different after oral administration three formulations. The results show adhesive formulations are superior to Fufang Danshen tablet (FDT); there are differences between the two adhesive, but not obvious. CONCLUSIONS: It was found that the modification with adhesive materials improved PNS bioavailability in Fufang Danshen formula. These findings provide a way for further in vivo evaluation of different formulations.
