Floating matrix tablets of Glimepiride were developed to enhance its bioavailability by prolonging the gastric residence time in which Glimepiride was chosen as a model drug because of its has incomplete absorption due to its low gastric residence time. Floating matrix tablets were prepared using melt granulation technique. Bees wax was used as a hydrophobic meltable material. Hydroxypropylmeth...

In the present work, the optimization of different structural and process parameters of a divided wall column (DWC) for the energy efficiency has been presented. The optimal design and operation of divided wall distillation columns involve a number of variables and is a non-linear problem. Rigorous simulation of a DWC was carried out using Multifrac model of ASPEN Plus software. Box–Behnken des...
