Claims
- 1. An oral active agent delivery system for delivering to a patient active agent in admixture with a fluid, comprising:
- a tubular active agent formulation chamber having a first end configured for fluid communication with the fluid and a second end configured for oral application of suction by the patient, wherein said first end is crimped to form a restriction in a cross-sectional area of said first end of said active agent formulation chamber that prevents release of active agent; and
- a removable tab, wherein said removable tab prevents release of active agent from said second end of said active agent formulation chamber prior to use by the patient.
- 2. The oral active agent delivery system of claim 1, further comprising:
- a quantity of discrete units that comprise the active agent disposed in said active agent formulation chamber, wherein each of said discrete units has a diameter greater than said restriction.
- 3. The oral active agent delivery system of claim 1, further comprising:
- a fluid passing plug disposed in said active agent formulation chamber, wherein said plug has a diameter greater than said restriction, said plug being transportable toward said second end upon application of suction by the patient.
- 4. The oral active agent delivery system of claim 3, further comprising:
- a quantity of discrete units that comprise the active agent disposed in said active agent formulation chamber between said second end and said fluid passing plug, wherein each of said discrete units has a diameter less than said restriction.
- 5. The oral active agent delivery system of claim 3, further comprising:
- a protrusion proximate said second end of said active agent formulation chamber, wherein said protrusion prevents release of said fluid passing plug from said second end.
- 6. The oral active agent delivery system of claim 2, wherein said quantity of discrete units comprises oral dosage forms that comprise an osmotic layer and an active agent layer.
- 7. The oral active agent delivery system of claim 4, wherein said quantity of discrete units comprises oral dosage forms that comprise an osmotic layer and an active agent layer.
- 8. The oral active agent delivery system of claim 1, further comprising:
- an end cap concentrically surrounding said first end of said active agent formulation chamber.
- 9. The oral active agent delivery system of claim 2, wherein said quantity of discrete units comprises an active agent selected from the group consisting of antibiotics, antiviral agents, anepileptics, anti-inflammatory agents, and bronchodilators.
- 10. The oral active agent delivery system of claim 4, wherein said quantity of discrete units comprises an active agent selected from the group consisting of antibiotics, antiviral agents, anepileptics, anti-inflammatory agents, and bronchodilators.
- 11. An oral active agent delivery system for delivering to a patient active agent in admixture with a fluid, comprising:
- a tubular active agent formulation chamber having a first end configured for fluid communication with the fluid and a second end configured for oral application of suction by the patient, wherein said first end is crimped to form a restriction in a cross-sectional area of said first end of said active agent formulation chamber that prevents release of active agent; and
- a removable seal, wherein said removable seal prevents release of active agent from said second end of said active agent formulation chamber prior to use by the patient.
- 12. The oral active agent delivery system of claim 11, further comprising: a quantity of discrete units that comprise the active agent disposed in said active agent formulation chamber, wherein each of said discrete units has a diameter greater than said restriction.
