Development and optimization of dispersible tablet of Bacopa monnieri with improved functionality for memory enhancement
2017
Introduction: The Bacopa monnieri is traditional Ayurvedic medicine, and reported for memory-enhancing effects. The Bacoside is poorly soluble, bitter in taste and responsible for the memory enhancement action. Memory enhancer is commonly prescribed for children or elder people. Objective: Poor solubility, patient compliance and bitterness were a major driving force to develop taste masked β-cyclodextrin complex and dispersible tablets. Materials and Methods: The inclusion complex of Bacopa monnieri and β-cyclodextrin was prepared in different molar ratios of Bacopa monnieri by Co-precipitation method. Phase solubility study was conducted to evaluate the effect of β-cyclodextrin on aqueous solubility of Bacoside A. The characterization was determined by Fourier transformation infrared spectroscopy (FTIR),Differential scanning calorimetry (DSC) and X-ray diffraction study (XRD).Crospovidone and croscarmallose sodium were used as super disintigrant.The 3 2 full factorial design was adopted to investigate the influence of two superdisintegrants on the wetting time and disntegration time of the tablets. Conclusion: The result revels that molar ratio (1:4) of inclusion complex enhance 3-fold solubility. Full factorial design was successfully employed for the optimization of dispersible tablet of B. monnieri . The short-term accelerated stability study confirmed that high stability of B. monnieri in inclusion complex.
