Abstract: The present invention relates to an extended release formulation of an antiepileptic agent. More particularly, the present invention relates to an extended release formulation of divalproex sodium. The present invention also relates to a process for the preparation of extended release formulation of divalproex sodium.

Abstract: An improved stable pharmaceutical composition for controlled release of an active ingredient comprises a betalactam antibiotic such as cephalexin, cefaclor or their pharmaceutically acceptable hydrates, salts or esters as active ingredient, a calcium salt and a mixture of hydrophilic polymers selected from the group consisting of at least one sodium alginate and one xanthan gum and with or without hydroxypropyl methylcellulose, said composition optionally containing probenecid. The composition may also contain one or more of a water soluble and/or water dispersible diluent, wherein the quantities of the hydrophilic polymers and water soluble and/or water dispersible diluents are such that the therapeutically effective active ingredient is released at a rate suitable for once or twice daily administration of the pharmaceutical composition.

Abstract: The technical field of the present invention relates to stable solid dosage form comprising combination of antihypertensive agents. More particularly, the present invention relates to stable solid dosage form comprising combination of angiotensin converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) and calcium channel blocker (CCB).

Abstract: A pharmaceutical composition in the form of a tablet for controlled release of an active ingredient comprises a betalactam antibiotic such as cephalexin, cefaclor or their pharmaceutically acceptable hydrates, salts or esters as active ingredient, and a mixture of hydrophilic polymers selected from the group consisting of at least one sodium alginate and at least one xanthan gum as controlled release matrix; and optionally probenecid as an antibiotic adjuvant as either immediate release or controlled release part. The composition may also contain one or more of a water soluble and/or water dispersible diluent, wherein the quantities of the hydrophilic polymers and water soluble and/or water dispersible diluents are such that the therapeutically effective active ingredient is released at a rate suitable for once or twice daily administration of the pharmaceutical composition.
