The key ingredient in successful pharmaceutical fulfillment is order accuracy. Incorrect fulfillment of an e-commerce order is typically just a nuisance to the customer. In the pharmaceutical world, however, an incorrectly filled order can be a matter of life-and-death if a life-saving product is not delivered in time or the wrong product is shipped. Pharmaceutical fulfillment can include everything from generic unit storage on shelves and carton flow, refrigerated storage of products that must be maintained at a specific temperature, to secure storage areas where narcotics and other regulated or high-valued drugs are stored. There are various systemic checks and balances throughout the process to ensure order accuracy is maintained. All FDA regulations regarding serialization and traceability, as required by the Drug Supply Chain Security Act (DSCSA), are met.
