1. An oral active agent delivery system for delivering to a patient discrete units of active agent formulation in admixture with a fluid, said system comprising:
- a tubular active agent formulation chamber, said chamber having a first end and a second end and containing an active agent formulation in the form of discrete units, said first end being adapted for fluid communication with a fluid and said second end being adapted for oral application of suction by the patient; and
a fluid passing active agent formulation retainer in said active agent formulation chamber for preventing release of the discrete units from the first end of the chamber while permitting fluid entry into the chamber, said retainer being transportable toward said second end of said chamber with the fluid entering said first end of said chamber upon application of suction at said second end.

15. A method for observing the delivery to a patient of a dose of active agent formulation in admixture with a liquid from a delivery system comprising a tubular member containing the active agent formulation and a transportable active agent formulation retainer positioned between the active agent formulation and the liquid, wherein the method comprises:
-
observing a first position of the active agent formulation retainer within the tubular member and observing a second position of the retainer within the tubular member after suctioning liquid through the tubular member upon oral application of sucking by the patient, and removing the suction.
