The present invention is directed to a fluid-imbibing drug delivery device which is useful for the initial delayed delivery of an active agent formulation to a fluid environment of use, the initial delay period to startup or activation being of a predetermined length of time. The dispensing device is formed of a first and second housing that are in reversibly sliding telescoping arrangement with each other. The first housing contains the active agent formulation and has an aspect ratio less than 1. The housings are preferably. ovoloid in shape.

The present invention is directed to an active agent dosage form which is useful for the prolonged delivery of an active agent formulation to a fluid environment of use. The active agent dosage form is a matrix that has on its surface two or more insoluble bands. The invention is also directed to the method for making the active agent dosage form.
摘要:
Oral active agent delivery system having improved flow controllers. A hollow tubular member containing the active agent formulation and having a fluid passing controller is placed at one end into a fluid and at a second end into a patient's mouth. The active agent is delivered when the patient sips on the end of the chamber. The improved controllers prevent leakage of the active agent formulation.
摘要:
The present invention is directed to a mixing system for an active agent delivery device. The device comprises an elongate tubular member having first and second ends and a mixing system. The mixing system enables the entire dose of active agent to be entrained in a liquid. In use, liquid is drawn into the first end of the device, the mixing system mixes the liquid and active agent within the device and the active agent entrained in the liquid is drawn out of the second end of the member and into the patient's mouth.

The present invention is directed to a closure system for an oral active agent delivery device. The device comprises an elongate tubular member having first and second ends. The closure system includes a deformable closure means adapted to allow delivery of the active agent upon deformation. The closure system prevents spillage and maintains the integrity of the dose within the device. In use, the closure system is deformed and separated from the second end of the tubular member, liquid is drawn up into the first end of the member, and the liquid and active agent are drawn out of the second end of the member and into the patient's mouth.
