摘要:
A dispenser for use in a fluid environment which is capable of delivery of plurality of discrete drug containing layers in any desired delivery pattern or profile. The dispenser comprises a rigid housing containing a plurality of drug layers which may be separated by drug-free layers. An outlet is provided at one end of the housing and a fluid actuated driving means is provided between the other end of the housing and the drug layers. The portion of the housing in proximity to the driving means has a controlled permeability to water whereby, upon immersion in a fluid environment the drug layers are driven towards the outlet. Various delivery patterns are possible by appropriate selection of the comparison and dimensions of the drug and drug-free layers.
摘要:
An osmotic system is disclosed comprising a wall comprising in at least a part of a semipermeable material that surrounds a compartment. The compartment contains an osmotic composition comprising a beneficial drug selected from the group consisting of nifedipine, prazosin and doxazosin, and a second and different osmotic composition. A passageway in the wall connects the first composition with the exterior of the system.
摘要:
An osmotic delivery system is disclosed for delivering a useful agent at a controlled and constant rate modulated by a pulsed delivery of the useful agent to an environment of use.

摘要:
The present invention includes an expandable osmotic layer and a coating suspension for providing an expandable osmotic layer, both of which are useful for the manufacture of controlled release dosage forms. The expandable osmotic layer of the present invention may be produced using the coating suspension of the present invention. Advantageously, the coating suspension of the present invention can be used to coat expandable osmotic layers under both wet and dry process conditions without sacrificing the quality of the expandable osmotic layers produced, and therefore provides a relatively robust coating suspension that facilitates commercial production of controlled release dosage forms including a coated expandable osmotic layer.
摘要:
A dosage form manufactured from an extruded polymer tube and method for manufacturing the dosage form are disclosed. The dosage form is preferably an osmotic dosage form and includes a therapeutic agent and an expandable composition contained within the lumen of the extruded polymer tube.
