Abstract: A pharmaceutical drug sample tracking and control method. Pharmaceutical drug manufacturers send pharmaceutical drug samples bearing pharmaceutical drug sample indicia to dispensing locations where an indicia reader is used to read the pharmaceutical drug sample indicia into a dispensing location database. As pharmaceutical drug samples are dispensed to patients, an indicia reader is used to read the pharmaceutical drug sample indicia on pharmaceutical drug samples thus dispensed into the dispensing location database. Inventory software tracks inventory levels by subtracting pharmaceutical drug samples dispensed to patients from the previous recorded inventories. Pharmaceutical drug manufacturers can access inventory levels at dispensing locations remotely. Practitioners enter patient information, practitioner information, adverse reaction information and patient outcomes in the dispensing location database. Interested parties can access this information.
