the formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a hydroph...

Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubili...

      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...

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...

The solubilizing ability of two aromatic hydrotropes, N,N-diethylnicotinamide (DENA) and N,N-dimethylbenzamide (DMBA), was investigated using a set of 13 poorly soluble, structurally diverse drugs. The number of aromatic rings in the solute molecule has a very strong effect on the solubility enhancement produced by either hydrotrope. However, although solubility enhancements in the order of 100...

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 ...
