Controlled release matrix tablet formulation using synthesized N-acyl Thiolated Chitosan derivatives

Formulation of Controlled Release Pelubiprofen Tablet Using Matrix-Forming Polymers

Formulation of sustained release matrix tablet using Chitosan/Ghatti gum polyelectrolyte complex

Chitosan/ghatti gum polyelectrolyte complexes were synthesized using different proportions of chitosan (CH) and ghatti gum (GG). The optimum CH: GG ratio was 20:80, which produced highest product yield. Polyelectrolyte (PEC) samples were characterized by differential scanning calorimetry (DSC) and FT-IR spectroscopy. Matrix tablets using PEC as matrix and Diltiazem Hcl as a model drug were form...

Formulation of Controlled Release Matrix Tablet of Diclofenac Sodium Using Cross Linked Starch Urea

The présent works aims to develop controlled release matrix tablet of diclofenac sodium with modified starch cross linked starch urea as an sustained release polymer and to evaluate the prepared dosage form for physical parameters like weight variation, hardness, friability and drug content. Cross linked starch urea is modified starch introducing desirable alterations in the starch structure so...

Formulation and evaluation of theophylline sustained release matrix tablet

In the present study sustained release matrix tablets of Theophylline were prepared by direct compression method using different grades and ratios of hydroxy propyl methyl cellulose in presence of ethyl cellulose to examine their influence on tablet properties and drug release profile. Theophylline is used to treat chronic obstructive pulmonary disease (COPD) and asthma. The drug has a narrow t...

Formulation and In-vitro Characterization of Sustained Release Matrix Type Ocular Timolol Maleate Mini-Tablet

The purpose of this study was preparation and evaluation of sustained release matrix type ocular mini-tablets of timolol maleate, as a potential formulation for the treatment of Glaucoma. Following the initial studies on timolol maleate powder, it was formulated into ocular mini-tablets. The polymers investigated in this study included cellulose derivatives (HEC, CMC, EC) and Carbopol971P. Mann...
