Wet Granulation to Overcome Liquisolid Technique Issues of Poor Flowability and Compactibility: A Study to Enhance Glibenclamide Dissolution

The aim of this study is to apply wet granulation on liquisolid powders to overcome issues of poor powder flowability and compressibility especially with using high viscosity liquid vehicles. Different liquisolid formulations were made using three excipients where the effect of each excipient used in the dissolution of the model hydrophobic drug (Glibenclamide) was evaluated. The Glibenclamide tablets were formulated using PEG 400, Synperonic PE/L44 and Cremophor ELP, at a 10 %w/w in liquid vehicle drug concentration. The carrier (Avicel®PH102) was used followed by colloidal silicon dioxide (coating material) that converted the wet mixture into dry powder. Potato starch, 5%w/w, as a disintegrant was mixed with the mixture manually for 10 minutes and was finalized by adding 0.75% of magnesium stearate as a lubricant.

Improvement in Latent Fingermark Detection on Thermal Paper using 5,6-Dimethoxy-1,2-indandione/PVP

A new method for improvement of 1,2-indandione-treated latent fingermarks on thermal paper will be described in this paper. Treatment with conventional techniques like ninhydrin in petroleum ether or DFO solution produces a black color on the thermosensitive side of thermal paper.
