Three processed lactose-cellulose blends of similar composition, particle size and true density were compared as direct compression excipients: one was prepared by dry granulation, one by extrusion-spheronization, and the commercial product Cellactose. Differences among their flow properties depended solely on their different sphericities. Unlike those of the other blends, Cellactose particles ...
The main aim of the present study was to evaluate the potential of orally disintegrating pellets (ODPs) as an approach for taste masking of bitter drugs, namely, Ambroxol hydrochloride (A-HCl) and Cetirizine dihydrochloride (C-DHCl). Pellets were prepared by extrusion/spheronization with Eudragit EPO, kyron T-134, Kyron T-314, mannitol, sorbitol, MCC (Avicel PH-101), sucralose, chocolate flavor...
Budesonide, a potent glucocorticoid, is used for the treatment of inflammatory bowel diseases. Current available oral formulations of budesonide have low efficacy against ulcerative colitis because of the premature drug release in the upper part of the gastrointestinal tract. In this paper a pH- and time-controlled colon-targeted pellet-based tablet of budesonide was established. Pellet cores w...
The present study was designed to investigate the effect of different types of coating polymers such as Eudragit RL 30D, Eudragit RS 30D, Eudragit NE 30D, Surelease, and Kollicoat SR 30D on physical properties and release pattern of salbutamol sulphate (SS) pellets which were prepared by Extrusion-Spheronization technology. All the polymers used in coating solution were in aqueous dispersion fo...
Purpose: Triple solid dispersion adsorbates (TSDads) and spherical agglomerates (SA) present new techniques that extensively enhance dissolution of poorly soluble drugs. The aim of the present study is to hasten the onset of hypoglycemic effect of glimepiride through enhancing its rate of release from tablet formulation prepared from either technique. Methods: Drug release from TSDads or SA tab...
*To whom all correspondence should be addressed. uring the past few decades, various types of oral controlled-release (CR) formulations have been developed to improve the clinical efficacy of drugs having short half lives as well as to increase patient compliance (1, 2). These formulations are designed to deliver drugs at a predetermined rate over a wide range of conditions and durations of the...
