An oral dosage form comprising a pharmaceutical tablet of one or more layers, one of which carries a biologically active substance; the formulation of said tablet includes different percentages of hydrophilic and lipophilic polymeric materials, and adjuvant substances. The tablets of the present invention show a release rate which is independent from the amounts of active substance present in the tablet.

Hydrophilic/lipophilic polymeric matrix dosage formulation

Pharmaceutical tablet, capable of delivering the active substance or the active substances, according to a predeterminable release profile, comprising a core with an external partial coating in which said core consists of 3 layers, wherein the upper layer contains an amount of the active substance with suitable excipients, the intermediate layer consists of polymeric material with retarding barrier function and the lower layer contains the remaining amount of the active substance with suitable excipients and said external coating consists of controlled permeability polymeric materials, applied by compression to the lower surface and to the lateral surface of the core.

Pharmaceutical tablet suitable to deliver the active substance in subsequent and predeterminable times

It is described a new method for the preparation of pharmaceutical tablets carrying poorly soluble in water principle; this method allows to obtain tablets with fast and/or slow release of the active principle. The peculiar feature is the fact that the poorly soluble in water active principle (es: nifedipine) is treated with a surfactant, during the granulation phase or whatever during the preparation process; the obtained product, subjected to a compression, produces pharmaceutical tablets which show high bioavailability of the carried active principle. This procedure can be used to prepare polymeric matrixes (with modified release), formed by tablets with one or more layers. The procedure of manufacture and the characteristics of the new finished tablet are described.

Controlled release pharmaceutical tablets containing an active principle of low water solubility

Pharmaceutical tablet consisting of a first layer containing one or more drugs with immediate or controlled release formulation, a second layer containing one or more drugs, either equal to or different from the first layer, with slow release formulation, and a low-permeability barrier-type layer coating said second layer or, alternatively, placed between the first and second layer and, if necessary, containing a drug.

Pharmaceutical tablet capable of liberating one or more drugs at different release rates

Tablet with controlled release of alfuzosine chlorhydrate

Described herein is a particular type of pharmaceutical tablet, for oral use, which is formed by one or more layers, and is specifically designed for controlled release of active principles that present problems of bio-availability linked to absorption in the gastro-intestinal tract, and in particular active principles that present an erratic and unpredictable absorption linked to the presence or absence of food at the level of the stomach and/or of the first portion of the small intestine, the said pharmaceutical form being characterized in that it is completely coated with one or more films of a biocompatible and biodegradable polymeric material.

Pharmaceutical tablet, completely coated, for controlled release of

A process is described for preparing pharmaceutical compositions by co-grinding or dry mixing the active substance with cyclodextrins or with hydrophilic polymer materials which swell on contact with water. Homogeneous compositions are obtained from which the active substance is released very rapidly into an aqueous medium.

Process for preparing pharmaceutical composition having an increased

A description is given of a pharmaceutical form for oral administration consisting of a two- or three-layers tablet, wherein at least one layer can rapidly swell by contact with biological and/or aqueous fluids, said swelling resulting in a considerable increase in the tablet volume. Said phenomenon determines a prolonged residence of the pharmaceutical form at the gastric level and therefore allows a slow release of the active ingredient from said pharmaceutical form to the stomach and/or the first tract of the intestine.

Pharmaceutical tablet characterized by a showing high volume increase

Pharmaceutical tablet capable of liberating one or more drugs at

Multilayered controlled-release oral solid pharmaceutical forms

A pharmaceutical tablet capable of releasing the active ingredients contained therein at subsequent times produced via the steps of: a) preparing a tablet consisting of three superposed layers, the upper layer containing an active ingredient, the intermediate layer not containing any active ingredient and forming a barrier-type layer, and the lower layer containing an active ingredient, said upper layer presenting a raised top, b) coating the tablet entirely with an impermeable polymeric film, and c) removing said raised top and thus allowing contact of the abraded upper layer surface with the environment.

Pharmaceutical tablet capable of releasing the active ingredients

Controlled release pharmaceutical tablet having a lenticular form consisting of three layers of which the central one or core (a) contains the active principle and the two outer layers or barriers (b) and (c) comprise gellable and/or erodible polymeric material, said barrier layers being equal or different among themselves for composition and/or thickness, while the central layer has a limited external annular surface exposed to the dissolution medium, through which the active principle is released.

Controlled release pharmaceutical tablet having lenticular form

Controlled release pharmaceutical compositions administrable by oral route, containing as the active principle at least one salt of the gamma hydroxy butyric acid with a pharmaceutically acceptable cation, for the treatment of alcoholism, opium like substances addiction, heroin addiction, food and nicotine addiction, depressive and anxious states, composed by:
