Abstract: The invention relates to the use of a preparation containing a first group of particles and at least one other group of particles which is not identical to the first group of particles for achieving controlled release of an active ingredient present in the cores of the particles, in particular in the human and veterinary medical sectors. The preparation is administered orally, rectally, vaginally etc. The release of the active ingredient then takes place in the appropriate medium, and there is transmucosal absorption of the active ingredient.
Abstract: A once-a-day controlled release drug delivery system of diltiazem hydrochloride is provided, which is bioequivalent in plasma profile of Cardizem CD. The fast, medium, and slow release fractions are prepared using various compositions and weight gains. The individual fill weights are computed and then are filled into the same capsule using specialized encapsulation equipment using a triple-filling process. A preferred membrane dispersion that is used for preparing the fast release fraction contains 0.2% of sodium lauryl sulfate along with 20% of water soluble plasticizer (triethyl citrate), and 2% silicone dioxide, based on quaternary polymethacrylate on the weight basis. This combination provides an initial pulsatile burst after a lag time of 2 hours, leading to in-vivo bioequivalence. The preferred membrane dispersion that is used for preparing the medium release and the slow release fractions contain 16% of water soluble plasticizer along with 5% silicone dioxide, based on quaternary polymethacrylate.

Abstract: The present invention is directed to an active agent dosage form which is adapted for retention in the stomach and useful for the prolonged delivery of a liquid, active agent formulation to a fluid environment of use. The liquid, active agent formulation is sorbed into porous particles that are dispersed in a polymer matrix that swells upon contact with the fluids of the stomach. A portion of the polymer matrix may be surrounded by a band of insoluble material that prevents the covered portion of the polymer matrix from swelling and provides a segment of the dosage form that is of sufficient rigidity to withstand the contractions of the stomach and delay expulsion of the dosage form from the stomach until substantially all of the active agent has been dispensed.
Abstract: The present invention relates to oral dosage forms comprising
a) one or more active ingredients
b) a formulated mixture of polyvinyl acetate and polyvinylpyrrolidone
c) where appropriate other excipients customary for producing the dosage form,
wherein they float on gastric fluid and display delayed release of active ingredient, and to the use and production thereof.

Abstract: The invention is directed to a device for delivering an active agent formulation for a predetermined administration period. An impermeable reservoir is divided into a water-swellable agent chamber and an active agent formulation chamber. Fluid from the environment is imbibed through a semipermeable plug into the water-swellable agent chamber and the active agent formulation is released through a back-diffusion regulating outlet. Delivery periods of up to 2 years are achieved.
