Abstract

A pharmaceutical order filling system receives pharmaceutical orders and uses an automated dispensing device to dispense pharmaceuticals into containers. The automated dispensing device is configured with a filling cabinet that stores and dispenses measured quantities of pharmaceuticals and is further configured to stage measured quantities of pharmaceuticals in buffer tubes to enable efficient fulfillment of the pharmaceutical orders. Containers may be disposed on a pallet which may be moved within an automated dispensing device to place the containers under buffer tubes to receive measured quantities of pharmaceuticals from the buffer tubes into appropriate containers in an efficient manner.

9. The system of claim 1, wherein the automated dispensing device is configured to generate an alert when the available quantity of the pharmaceutical in the cell is less than a pre-determined level.

10. The system of claim 1, wherein the system further comprises a pallet assembly, wherein the container is disposed on a pallet, and wherein a pallet assembly comprises an x-y movement apparatus adapted to engage and move the pallet within the pallet assembly such that the container is positioned below the buffer tube to receive the first measured quantity of the pharmaceutical.

11. The system of claim 10, wherein an opening of the container is less than approximately 0.01 inches from a buffer tube exit of the buffer tube when the first measured quantity of the pharmaceutical is dispensed into the container.

3. (canceled)
