Novel Polyvinylpyrrolidones To Improve Delivery of Poorly Water-Soluble Drugs: From Design to Synthesis and Evaluation

Novel polyvinylpyrrolidones to improve delivery of poorly water-soluble drugs: from design to synthesis and evaluation.

Polyvinylpyrrolidone is widely used in tablet formulations with the linear form acting as a wetting agent and disintegrant, whereas the cross-linked form is a superdisintegrant. We have previously reported that simply mixing the commercial cross-linked polymer with ibuprofen disrupted drug crystallinity with consequent improvements in drug dissolution behavior. In this study, we have designed a...

Novel Strategies for Poorly Water Soluble Drugs

Solubility of drug plays critical role in achieving the optimum therapeutic levels of the drug in blood and thus bioavailability. There are many drugs of various therapeutic categories fall in BCS class II and IV as they lack solubility. For all these drugs dissolution is the big hurdle for the absorption process. Present review’s focus is mainly on novel techniques of improving the solubility ...

Nanosized Technological Approaches for the Delivery of Poorly Water Soluble Drugs

      A major hurdle in pharmaceutical formulation is water insolubility of most of drugs affecting their stability and bioavailability. If the drug is also insoluble in organic medium, it is difficult to deliver it in a sufficiently bioavailable form and hence it is a great challenge to formulation researchers to overcome such difficulty. Although some approaches are available for enhancing th...

Nanocrystal Technology For Oral Delivery of Poorly Water-Soluble Drugs

Nanotechnology has been improving and has a variety of application fields. One of the major application areas of nanotechnology in pharmacy is nanoparticular drug delivery systems. Preparation of drug nanocrystals to improve the solubility of poorly water-soluble drugs for oral delivery is also one of the important applications. Nanocrystal dispersions comprise water, active drug substance and ...
