Characterization and in vitro drug release studies of a natural polysaccharide Terminalia catappa gum (Badam gum).

abstract：:Solubility challenge for a poorly water-soluble drug gets further intensified when it is weakly ionic because the most common solubility enhancement technique, salt formation, becomes less feasible. Salt screening for such drugs often concludes with either a difficult to crystalize salt or an unstable salt, leading th...
