Patent number: 5997902Abstract: The present invention is concerned with improving the delivery of a drug from a ruminal delivery device to give a consistent delivery of drug to the ruminal environment. Thus, the invention is directed to an improved ruminal drug delivery device comprising a semipermeable membrane having an exit orifice and defining a compartment, the compartment containing a swellable osmotic agent expandable driving member, a drug to be dispensed, a density element and, optionally, a partition layer between the osmotic expandable driving member and the drug formulation, wherein the improvement comprises an essentially gas-impermeable barrier means that separates the density element from the other components within the delivery device for isolating gases evolved from the density element from the other components within the delivery device. The barrier means further includes a coupling to transfer osmotic pressure to the semipermeable wall.Type: GrantFiled: August 3, 1998Date of Patent: December 7, 1999Assignee: Alza CorporationInventors: Frederick H. Maruyama, Judy A. Magruder

Patent number: 5985305Abstract: 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.Type: GrantFiled: October 2, 1997Date of Patent: November 16, 1999Assignee: Alza CorporationInventors: John R. Peery, Keith E. Dionne, James B.

Patent number: 5318558Abstract: A drug delivery capsule from which the delivery of the drug is driven by the osmotic infusion of moisture by the capsule from a physiological environment is provided with a delivery orifice which opens intermittently to achieve a pulsatile delivery effect. The wall in which the orifice is formed is constructed of an elastic material, preferably an elastomer, which stretches under a pressure differential caused by the pressure rise inside the capsule as the osmotic infusion progresses. The orifice is small enough that when the elastic wall is relaxed, the flow rate of drug through the orifice is substantially zero, but that when the elastic wall is stretched due to the pressure differential across the wall exceeding a threshold, the orifice expands sufficiently to allow the release of the drug at a physiologically beneficial rate.Type: GrantFiled: December 1, 1992Date of Patent: June 7, 1994Assignee: ALZA CorporationInventors: Andreas Linkwitz, Judy A.
