In titrimetric analysis costlier organic solvents are more often employed to solubilize the poorly water-soluble drugs. Volatility and pollution are drawbacks of such solvents. Various techniques are employed to enhance the aqueous solubility of poorly water-soluble drugs. Hydrotropic solubilization phenomenon has been widely used to enhance the aqueous solubility of large number of poorly water-soluble drugs. Aqueous solubility of aceclofenac bulk drug [a poorly water-soluble NSAID] was enhanced to a great extent i.e., 400 folds with 2.5 M sodium salicylate. The primary objective of the present investigation was to employ this hydrotropic solution to extract the drug from its dosage forms, precluding the use of costlier organic solvents. The proposed method of analysis is new, simple, accurate, environmentally friendly and reproducible. Statistical data proved the accuracy, reproducibility and the precision of the proposed method. The results of titrimetric analysis by use of hydrotropy compared very well with the results of Pharmacopoeial method.

The supercritical antisolvent (SAS) method can effectively improve the bioavailability of poorly water-soluble drugs. However, the current supercritical equipment and processes were not fully developed, making industrialization difficult to achieve. Therefore, an externally adjustable annular gap nozzle and its supporting equipment were designed.

Introduction: Liquisolid (LS) technology is particularly advantageous for poorly water-soluble drugs administered in very low doses because of the improved dissolution rate and superior content uniformity. However, there is a lack of research papers describing the application of this concept on an industrial scale. Thus, we present trials conducted to develop tablets containing 0.

Background/objectives: Selective laser sintering (SLS) is one of the most promising 3D printing techniques for pharmaceutical applications as it offers numerous advantages, such as suitability to work with already approved pharmaceutical excipients, the elimination of solvents, and the ability to produce fast-dissolving, porous dosage forms with high drug loading. When the powder mixture is exposed to elevated temperatures during SLS printing, the active ingredients can be converted from the crystalline to the amorphous state, which can be used as a strategy to improve the dissolution rate and bioavailability of poorly soluble drugs. This study investigates the potential application of SLS 3D printing for the fabrication of tablets containing the poorly soluble drug carvedilol with the aim of improving the dissolution rate of the drug by forming an amorphous form through the printing process.
