This paper describes a new strategy to generate nanocrystalline drugs through the precipitation of drug molecules in attoliter nanowells. We controlled the size of arsenic trioxide (ATO) nanocrystals by simply changing the concentration of ATO solution in the nanowells; particles with sizes ranging from 55 to 175 nm were formed. This approach only requires the drugs to be soluble in a solvent a...

Gold nanoparticles functionalized with water-soluble zwitterionic ligands form kinetically stable complexes with hydrophobic drugs and dyes. These drugs and dyes are efficiently released into cells, as demonstrated through fluorescence microscopy and cytotoxicity assays. Significantly, there is little or no cellular uptake of particle, making these low toxicity particles promising for delivery ...

Pharmacological approach to heart failure with reduced ejection fraction (HFrEF) is evolving, as recently published large randomized clinical trials have implemented the disposal of HFrEF treatments four new classes drugs, namely angiotensin receptor/neprilysin inhibitor , sodium-glucose co-transporters 2 inhibitors soluble guanylate cyclase modulators and myosin activators, which proved furthe...

Context: Nigella sativa Linn. (Ranunculaceae) is native to southwest Asia. This tree species has been of interest to researchers because it has a long history of folklore usage in various systems of medicines. Objective: Pharmacognostic Standardization, Physico and Phytochemical Evaluation of the seeds of N. sativa were carried out to determine its macro-and microscopical characters and also so...

Based on the large number experiments on solubilization of poorly watersoluble drugs, the author is of the opinion that hydrotropy is another type of cosolvency and all water soluble substances whether solids, liquids or gases have solubilizing properties. Therefore, aqueous solutions containing small quantities of several water-soluble excipients giving a concentrated solution, may act as a so...

A target of best dissolution improvement of poorly soluble drugs is a necessity for the success of formulation in industry. The present work describes the preparation, optimization, and evaluation of a new spherical agglomeration technique for glimepiride as a model of poorly soluble drugs. It involved the emulsification of a drug solution containing a dispersed carrier that tailors the crystal...

       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 ...

Sustained release of thermal-instable and water-soluble drugs with low molecule weight is a challenge. In this study, sodium bicarbonate was encapsulated in ethyl cellulose microspheres by a novel solid-in-oil-in-oil (S/O/O) emulsification method using acetonitrile/soybean oil as new solvent pairs. Properties of the microspheres such as size, recovery rate, morphology, drug content, and drug re...
