Improving oral bioavailability of drugs those given as solid dosage forms remains a challenge for the formulation scientists due to solubility problems. The dissolution rate could be the rate limiting process in the absorption of a drug from a solid dosage form of relatively insoluble drugs. Therefore increase in dissolution of poorly soluble drugs by solid dispersion technique presents a challenge to the formulation scientists. Solid dispersion techniques have attracted considerable interest of improving the dissolution rate of highly lipophilic drugs thereby improving their bioavailability...

The shoot apex, leaf, nodal stem and internodal stem of Stevia rebaudiana, a natural substitute for artificial sweetener having glycosides upto 400 times sweeter than sugar, were cultured on 21 different media having different concentrations and combinations of auxins (2,4-D, IBA, NAA) and cytokinins (KIN, BA) supplemented to MS basal medium. Besides these explants the formed callus and developed shoot were also cultured. The tissue culture experiments resulted in establishment of cultures, swelling of explants, elongation of existing shoot, callus formation, caulogenesis, rhizogenesis and...
