Wet granulation is the most commonly used technique in the pharmaceutical industry for delivering oral solid dosage forms. In wet granulation, the binder solvent is one of the critical factors affecting granule properties. In the current study, an attempt was made to investigate the effect of solvents (aqueous and hydro-alcoholic) on thermal and flow properties of Microcrystalline Cellulose (MCC) granules prepared using two different grades of Hydroxypropyl Methylcellulose (HPMC), which served as an effective binder.

A Design of Experiment (DoE) methodology was adopted to investigate and optimize process parameters and formulations variables for preparing an amorphous clotrimazole (CLT) nanosuspension by sonoprecipitation technique. The amorphous nanosuspension can provide a synergistic effect of increase in dissolution velocity and kinetic solubility which can be advantageously used to improve bioavailability of low-solubility drugs. A Box-Behnken design was utilized to study the effect of formulation parameters (drug concentration, polymer concentration, and surfactant concentration) and process parameter (antisolvent: solvent ratio) on particle size, polydispersibility index (PDI), and zeta potential of amorphous CLT nanoparticles.

The hot melt extrusion (HME) technology was explored and optimized to solidify an amorphous nanosuspension using Quality by Design (QbD) methodology. A design of experiments (DoE) approach was used to perform a set of 15 experiments, varying independent variables (feed rate, input temperature, and screw speed) within a design space. Redispersibility index (RDI), moisture content, and process yield constituted the critical quality attributes (CQAs) of the experimental design.

Wet milling is a multifunctional and the most common method to prepare a drug nanosuspension for improving the bioavailability of poorly water soluble drugs. A suitable way of preparing a high drug-loaded nifedipine nanosuspension using wet stirred media milling was investigated in the present study. Nifedipine, a poorly water soluble drug, was selected as a model drug to enhance its dissolution rate and oral bioavailability by preparing an appropriate crystalline nanosuspension.

The objective of the present study was to investigate the influence of processing methods on the physical and mechanical properties of formulations containing Ibuprofen and HPC-SSL. The powder blends, containing Ibuprofen and HPC-SSL in ratio of 9:0.5, were processed using melt granulation (MG) by hot melt extrusion (HME) and wet granulation (WG) by high shear mixer.
