A sustained-release composition for oral administration of a drug, comprising the drug, a mixture of sodium alginate and xanthan gum as a carrier for sustained release and a mixture of hydroxypropyl methylcellulose and propylene glycol alginate as a gel hydration accelerator, which is capable of maintaining a constant drug level in blood for 24 hours or more. Due to rapid gel hydration without forming a non-gelated core, the drug release rate follows zero order kinetics and does not significantly vary with the degree of gastrointestinal motility.

Sustained release composition for oral administration of drugs

Amlodipine camsylate of the present invention is a crystalline salt of amlodipine suitable for pharmaceutical formulation, which is prepared by using low toxic camphor sulfonic acid to meet required pharmaceutical properties for treating cardiovascular diseases.

Amlodipine camsylate and method for preparing thereof

A non-crystalline cefuroxime axetil solid dispersant showing no absorption peak on a Differential Scanning Calorimetry scan is prepared by (a) dissolving cefuroxime axetil and a surfactant in an organic solvent; (b) suspending a water-insoluble inorganic carrier in the resulting solution; and (c) drying the resulting suspension to remove the organic solvent, said solid dispersant having an improved bioavailability and stability of cefuroxime axetil and being useful for the preparation of a pharmaceutical composition for oral administration.

Non-crystalline cefuroxime axetil solid dispersant, process for
