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...
متن کاملNanonization strategies for poorly water-soluble drugs.
Poor water solubility for many drugs and drug candidates remains a major obstacle to their development and clinical application. Conventional formulations to improve solubility suffer from low bioavailability and poor pharmacokinetics, with some carriers rendering systemic toxicities (e.g. Cremophor(®) EL). In this review, several major nanonization techniques that seek to overcome these limita...

Objective(s): Development of an oral sustained-controlled release vehicle which, slowly releases the drug and maintains an effective drug concentration for a long time is aimed.Materials and Methods: A biodegradable magnetic polymeric drug delivery vehicle, using superparamagnetic iron oxide nanoparticles encapsulating by polyvinylpyrrolidone-block-polyethylene glycol-block-poly methacrylic aci...
متن کاملNovel 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 ...
متن کاملInfluence of particle design on oral absorption of poorly water-soluble drug in a silica particle-supercritical fluid system.
The physicochemical characteristics and oral absorption of a poorly water-soluble drug, K-832, adsorbed onto porous silica (Sylysia 350), were compared with those of K-832 adsorbed onto non-porous silica (Aerosil 200). K-832 and silica were treated with supercritical CO(2) (scCO(2)) to produce K-832-Sylysia 350 and K-832-Aerosil 200 formulations. Scanning electron microscopy, polarizing microsc...
