Form changes during drug product processing can be a risk to the final product quality in terms of chemical stability and bioavailability. In this study, online Raman spectroscopy was used to monitor the form changes in real time during high shear wet granulation of Compound A, a highly soluble drug present at a high drug load in an extended release formulation. The effect of water content, temperature, wet massing time and drying technique on the degree of drug transformation were examined.

ABSTRACT: Bosentan is an endothelial receptor antagonist (ERA) indicated for the treatment of Pulmonary arterial hypertension (PAH). The aim of the present study involves the development of controlled release tablets of bosentan1. The tablets were prepared to release the drug for a prolong period of time within the GIT, to enhance the bioavailability, to minimize the dosing frequency, and to improve the patient compliance2. The tablets were formulated by using various polymers like hydroxyl...

Abstract Aim: To prepare BSA loaded chitosan nanoparticles by polymerization technique and to study the effect of initiator concentration upon particle size, product yield, entrapment efficiency, loading capacity and drug release from the formulation. Methodology: In the present study BSA loaded chitosan nanoparticles were prepared by polymerization technique. Three formulations were prepared by varying the concentration of Initiator. The concentration of Initiator (Ammonium per sulphate) was...

Abstract: The purpose of the present study was to prepare floating matrix tablets of clarithromycin employing simplex lattice design. Hydroxypropyl methylcellulose (HPMC) and Ethyl Cellulose (EC) were used as matrix forming agents; sodium bicarbonate and citric acid as effervescence producing agents. Simplex lattice design was used as optimization technique employing three independent formulation variables viz. concentration of HPMC (X1), Citric Acid (X2), EC (X3) whereas floating lag time,...
