Croscarmellose Sodium Efficiency in the Development of a Generic Capsule Formulation of Piroxicam, Comparable Dissolution Profile to the Innovator Product, Feldene

The objective of this study was to evaluate the encapsulation performance of Croscarmellose sodium, a superdisintegrant in a low-dose, poor-solubility drug formulation and the in-vitro dissolution performance of the Piroxicam capsules. Preparation, characterization and evaluation of the effects of the different concentrations of carmellose sodium and the amount of dried starch on in-vitro dissolution of Piroxicam capsules. Piroxicam was chosen for its very low solubility in biological fluids, which result in poor systemic bioavailability after oral administration. Piroxicam can be categorized as Class II drugs according to the Biopharmaceutics Classification System.

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.
