In the field of nanomedicine, the global trend over the past few years has been toward the design of highly sophisticated drug delivery systems with active targeting and/or imaging capabilities, as well as responsiveness to various stimuli to increase their therapeutic efficacy. However, providing sophistication generally increases complexity that could be detrimental in regards to potential ph...

Cefpodoxime Proxetil (Poorly water soluble drug), when prepared as solid dispersion showed improved solubility and dissolution. So the main purpose of this investigation was to increase the solubility and dissolution rate of Cefpodoxime Proxetil by the preparation of its solid dispersion with urea using solvent evaporation method. Physical mixtures and solid dispersions of Cefpodoxime Proxetil ...

The solubility, bioavailability and dissolution rate of drugs are important parameters for achieving in vivo efficiency. The bioavailability of orally administered drugs depends on their ability to be absorbed via gastrointestinal tract. For drugs belonging to Class II of pharmaceutical classification, the absorption process is limited by drug dissolution rate in gastrointestinal media. Therefo...

Characterization and Evaluation of the Release Kinetics a Model Poorly Water-Soluble Low Dose Drug from Matrix Tablets Composed Blends Swellable Erodible Polymers: Implications for Controlled Complete ReleaseAiman A. Obaidat

Development in the field of pharmaceutical administration has resulted in the discovery of highly sophisticated drug delivery systems that allow for the maintenance of a constant drug level in an organism. Contrary to these revolution biopharmaceutical results, over the last ten years, the number of poorly soluble drugs has steadily increased. Estimates state that 40% of the drugs in the pipeli...

The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioav...
