摘要:
The present invention relates to delayed release coated cores comprising an active substance in their core and a polymer coating comprising at least one or more ammonio methacrylate copolymer, characterised in that the core comprises at least a surfactant; to monolithic or multiparticulate pharmaceutical dosage forms comprising such delayed release coated cores and to their method of manufacture.
摘要:
The invention concerns a pharmaceutical composition with gastric residence and controlled release, characterised in that it comprises two or three layers and contains: (a) an active principle associated with a excipient modifying its release; (b) a system generating carbon dioxide in a swelling polymer hydrophilic matrix; (a) and (b) capable of being included in a common layer or in separate layers.
摘要:
The present invention relates to timed dual release dosage forms of short acting hypnotics or salts thereof adapted to release the short acting hypnotic over a predetermined time period, according to a profile of dissolution characterised in that it comprises two release pulses, the first being immediate (lasting up to 30 minutes) and the second being delayed by a fixed time (this fixed time being between 50 and 200 minutes).
