The present work was to prepare and evaluate colon specific meloxicam loaded microspheres for the treatment of rheumatoid arthritis. Sodium alginate microspheres were prepared by using emulsification method using different ratios of sodium alginate (1:1, 1:2, 1:3 and 1:4). Prepared microspheres were coated with eudragit S100. The microspheres were characterized for different physical parameters...

Objective: The present research is focused on developing flurbiprofen colon-specific tablets based on timed release and pH-sensitivity. Methods and Material: This study is designed to study the effect of eudragit coating on the drug release from hydroxypropyl methylcellulose matrix to achieve the colon-specific release. Hydroxypropyl methylcellulose matrix tablets were prepared by wet granulati...

Shellac is an important coating material for food products. Since the introduction of aqueous ammoniacal solutions it also regained importance for pharmaceutical applications. Because of the comparatively high dissolution pH of this material, further additives are required if shellac is used as enteric coating material. However, this dissolution behaviour of shellac may be of interest for susta...

In the present investigation, pulsatile release beads were prepared by ionic gelation technique. Lornoxicam dual cross-linked beads were prepared by dropping dispersed phase of lornoxicam, pectin, and sodium alginate into the dispersion phase of different concentrations of calcium chloride solution followed by aluminium chloride solution. The formulated beads were further coated by Eudragit L &...

The aim of the present study is to investigate the effect of Ammonio Methacrylate Copolymer Type B (Eudragit RS 30 D) on the release kinetics study of diclofenac sodium form coated pellets. The effect of the incorporation of xanthan gum into the coating formulation was also the goal of this study. Eudragit RS 30 D and xanthan gum was added into the formulation at 5:1 ratio. Different percent of...

the influence of various polymers on the release rate of lithium carbonate from matrix-type tablets was investigated in an attempt to formulate a sustained release solid dosage form. for this purpose, tablets containing 450 mg of lithium carbonate along with various amounts of carbopol 934p, 971p, 974p, pemulen and eudragit rlpo as retarding agents and inactive ingredients (e.g. pvp, avicel or ...
