Metoprolol succinate (M.succinate), a BCS Class I drug is the most widely prescribed anti-hypertensive drug and is considered to be safe. Owing to its high solubility, fabrication of an extended release matrix formulation becomes extremely challenging. Hydrophilic matrix polymers are the preferred systems for developing an extended release formulation. However, for highly soluble drugs, it fail...
In this study, a novel approach for compression of matrix pellets into disintegrating tablets has been studied in an attempt to overcome the issues pertaining to rupture of polymer coat during compression of reservoirtype pellets. Extended release matrix pellets were prepared by the extrusion/spheronization technique using commercially available aqueous dispersions of ethyl cellulose, acrylic p...
megaloporous controlled release tablets of diclofenac sodium (ds) were prepared with two kinds of granules. one of them is the restraining-phase matrix granule (rmg) and it controls the release rate of the drug. the other one is the soluble housing-phase matrix granule (hmg) and controls liquid penetration into the system. carnauba wax and eudragit l 100 polymers were used to constitute the res...
Formulations for sustained medication release are very useful in the treatment of chronic disorders. The oral route has selected matrix tablets as most likely type prolonged drug release. In order to generate therapeutic activity a protracted duration, maintain stable plasma concentration and sustain rate throughout time. preparations with short half-life high dosage frequency, extended-release...
FocalinTM XR (dexmethylphenidate hydrochloride) extended-release capsules is an extended-release formulation of dexmethylphenidate with a bi-modal release profile. FocalinXR uses the proprietary SODASTM (Spheroidal Oral Drug Absorption System) technology. Each bead-filled Focalin XR capsule contains half the dose as immediate-release beads and half as enteric-coated, delayed-release beads, thus...
The aim of this study was to develop and optimize a segregation-free ethyl cellulose-coated extended release multiparticulate formulation to be compressed into tablets without affecting the drug release. Standard tableting excipients (e.g., microcrystalline cellulose, lactose or sorbitol) were layered onto ethyl cellulose-coated propranolol hydrochloride pellets to form a cushion layer in order...
