title: Preparation, characterization and evaluation of Marsupsin-phospholipid complex.
abstract: The aim of this research was to formulate Marsupsin-phospholipid complex (M-P Complex) in attempt to increase the bioavailability of marsupsin and to characterize this new formulation along with its evaluation. Marsupsin-phospholipid complex was formulated by mechanical dispersion method. In this new formulation, complex formation was confirmed by carrying out transmission electron microscopy (TEM), IR, (1)H-NMR and RP-HPLC analysis. TEM showed M-P Complex diameter range of 0.05-0.5 microm. The entrapment efficiency of M-P Complex was found to be 44%. In vitro release study revealed its first order release profile. Mean blood serum concentration vs time curve of marsupsin was of first order after oral administration of M-P Complex in albino rabbits which clearly showed remarkably increased bioavailability of M-P Complex than standardized marsupsin. The average value of C(max) and T(max) of M-P Complex were found to be 3.02 mg/ml and 10.2 h, respectively. Hence the findings demonstrate that complexing marsupsin with phospholipids results in better oral bioavailability and improved biological response than free form of standardized marsupsin.
