Abstract: The novel sustained release dosage form comprising an active agent and a combination of a non-swelling pH dependent release retardant and a non swelling pH independent release retardant polymer which provides pH-independent drug release for a considerable period of time after administration.

Abstract: The present invention provides a controlled release oral pharmaceutical composition having a therapeutically effective amount of one or more pharmacologically active agent having low bioavailability; one or more solubilizers; one or more biocompatible swelling agents; and a swelling enhancer. The swelling agent, in combination with swelling enhancer, swells in the presence of water in gastric fluid such that the size of the dosage form is sufficiently increased to provide retention of the dosage form in the stomach of a patient, which gradually erodes within the gastrointestinal tract over a prolonged time period.

Abstract: The present invention relates to the method of increasing the bioavailability of Angiotensin II Receptor Blockers (ARBs) by preparing a composition of an ARB with at least one solubility enhancing agent. The invention is particularly focused to provide a novel or modified dissolution profile where the release of ARB in the GI tract is independent of physiological pH conditions.

Abstract: The present invention describes a directly compressible composite prepared by co-processing a water-soluble excipient and calcium silicate. The present invention further describes the incorporation of the co-processed composite into a tablet formulation. The orally disintegrating tablets are of optimal mechanical strength and disintegrate within 60 seconds in the oral cavity.

Abstract: A novel solid oral dosage form comprising a therapeutically effective amount of hydrophobic pharmacological active ingredient and at least one particle separating agent preferably selected from a class of wetting agents, prepared without or with minimum amount of a disintegrating agent. The hydrophobic pharmacological active ingredient active ingredient belongs to the class of angiotensin receptor blocking agents preferably is valsartan optionally in combination with hydrochlorothiazide. The active ingredient may also be a class of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors preferably atorvastatin. The ratio of hydrophobic active ingredient to particle separating agent is about 20:1 to about 1:20. The process for the preparation of the novel solid oral dosage form comprises treating a hydrophobic active ingredient with at least one particle separating agent, and incorporating the treated hydrophobic active ingredient into a solid dosage form.

Abstract: The novel sustained release dosage form comprising an active agent and a combination of a non-swelling pH dependent release retardant and a non swelling pH independent release retardant polymer which provides pH-independent drug release for a considerable period of time after administration.

Abstract: The present invention provides a controlled release formulation comprising an therapeutically effective amount of pharmacologically active substance having high water solubility, at least one non-polymeric release retardant, and at least one pH independent non-swelling release retarding polymer. The said dosage form provides controlled release of the active agent with reduced initial burst release.

Abstract: The invention relates to a multifunctional fiber rich fraction (FRF) useful as an excipient for pharmaceutical dosage forms for various routes of administration. This excipient can be used as binder, disintegrant, filler, dispersing agent, coating agent, film forming agent, thickener etc for preparation of variety of dosage forms. This FRF can also be used in a controlled release, targeted release and other specialized delivery systems, as well as in food and cosmetics formulation.

Abstract: The present invention is for an oral osmotic controlled drug delivery system for a sparingly soluble drug comprising: a. a core comprising (i) finely particulate anhydrous carbamazepine (ii) a polymeric swelling agent consisting of one or more swellable hydrophilic polymers selected such that the polymeric swelling agent exhibits controlled swelling and the wall does not rupture or burst, (iii) a crystal habit modifier in whose presence, upon contact with an aqueous medium, the anhydrous carbamazepine being transformed into cuboidal or rod-shaped crystals of the dihydrate of carbamazepine, or mixtures thereof, and (iv) water-soluble compounds for inducing osmosis, b. a wall made of acylated cellulose which is impermeable to the components of the core, but permeable to water, and c. a passageway through the wall for releasing the components present in the core to the surrounding environment.
