We investigated the RESS process as a means of simultaneous micronization and cocrystallization of a model drug with poor aqueous solubility. 1:1 cocrystals of ibuprofen (IBU) and nicotinamide (NA) were produced with a pilot scale unit for RESS processing.IBU and NA were dissolved in scCO2 at 30 MPa and 50°C. After 24 h, the supercritical solution was(More)
Laminar extrusion of wet masses was studied as a novel technology for the production of dosage forms for oral drug delivery. Extrusion was carried out with a ram extruder. Formulations contained either microcrystalline cellulose (MCC) or dicalcium phosphate (DCP) as diluent, hydroxypropyl methylcellulose (HPMC), lactose, and water. Extrudates were(More)
Design of a new dosage form manufactured by laminar extrusion for oral administration of drugs. Different mixtures of materials (microcrystalline cellulose [MCC], hydroxypropyl methylcellulose [HPMC], lactose [LAC], dicalcium phosphate [DCP], coumarin [COU], propranolol hydrochloride [PRO], water [W]) were prepared prior to laminar extrusion. Mono, bi and(More)
