A medication storage and dispensing workstation for use in a medication management system administering the inventory and distribution of pharmaceuticals and medical supplies in a healthcare environment is disclosed. The workstation incorporates a linear drawer assembly having a plurality of discrete, removable, storage modules for containing medications and/or other medical supplies. The storage modules are arranged in a linear array extending longitudinally along the travel path of the linear drawer assembly. Each storage module, in turn, comprises a drawer that is extensible laterally relative to the linear arrangement of the storage modules. As such, the drawer assemblies comprise a compartmentalized “drawer-in-drawer” arrangement that provides an efficient use of storage space and enables a user to utilize the workstation in a workspace having a smaller footprint that traditional storage cabinet apparatus.
