ABSTRACT:
A system and method for manufacturing oral osmotic drug delivery devices including the use of a mathematical model in deriving relationships between parameters used in manufacturing the devices for a desired release rate of the active drug substance contained therein. The derived relationship is then used to control the parameters so that the active substance within the device is delivered at a desired rate. Methods of administering the oral osmotic drug delivery devices are also provided. Use of a mathematical model in deriving relationships between parameters used in the drug granulation process for a desired range of percentage fines of the drug granulation substance. The derived relationship is then used to control the parameters in the drug granulation process so that the desired percentage fines are obtained in the drug granulation substance.
